[07:21] <Kevin[m]2> I have an external hdd connected to my Homeserver and shared it over nfs with multiple clients. After a certain time of inactivity the hdd goes into standby (spins down). Now if I open caja on any of the clients the hdd turns on again and I have to wait until it is done before caja is responsive again although I am not accessing any folder on my hdd.
[07:21] <Kevin[m]2> Does anybody know how I can prevent caja from waking up my hdd?
[07:21] <ouroumov_> Hi Kevin[m]2
[07:22] <ouroumov_> Kevin[m]2, I don't know, but this could be an interesting conversation to have on our forums
[07:23] <Kevin[m]2> Thanks, I may try it there if nobody knows about that here.
[08:39] <christ_> hi every one all of you . beginner on ubuntu mate on raspberry pi 3 . ubuntu mate still litlle slow .how can i make it faster ? thanks all .
[08:39] <alkisg> christ_: buy a real computer, for example an i3 is 50 times faster than rpi3 :)
[08:39] <alkisg> rpi3 is like a mobile phone, it can't run as fast as desktop systems...
[08:40] <alkisg> It's good for programming or for text mode applications or meteo stations though
[08:44] <christ_> well it is just for internet purpose check email ... enought for me , but i m looking to make faster and be comfortable .
[08:44] <Astro7467> christ_:
[08:44] <Astro7467> Are you using the latest Rpi3 image of 16.04.2? Some improvements there
[08:46] <christ_> yep
[08:47] <Astro7467> other gains can be had by boot to or from a USB (there are firmware updates to support this - have done with Raspbian but yet to test with UM)
[08:48] <Astro7467> Boot to USB mean using the SD for th eboot partion then handing over to USB stick - doesn't require firmware updates
[08:48] <christ_> i like very much ubuntu mate .look good
[08:49] <christ_> i just install yesterday on rpi3. i m ubuntu user still many years...
[08:51] <christ_> i love ubuntu . i was using compiz on other comp but under rpi3 i m scared it will be too much ressource system taking
[09:48] <christ_> can t open a video on facebook . ressource system too much not enought . i got 1GO of ram on rpi3 .not enought ? i think it is maybe ubuntu too fat too
[09:49] <alkisg> rpi doesn't have enough CPU to play youtube videos
[09:49] <alkisg> It does have enough GPU (graphics power), but firefox doesn't use GPU
[09:53] <ouroumov> alkisg, uh
[09:53] <ouroumov> alkisg, I've been watching Youtube on firefox with no issue on a rpi 3 with UM16.04.2
[09:54] <alkisg> ouroumov: click full screen
[09:54] <alkisg> Do you have more than 5-10 fps there?
[09:54]  * alkisg doubts it
[09:55] <ouroumov> I had enough fps to watch SpaceX CRS-10 mission without lag.
[09:56] <alkisg> Full screen?
[09:56] <ouroumov> Yes. Now granted, the resolution of said screen was SD but still...
[09:56] <alkisg> I think rpi3 cpu can decode up to something like 640x480 at 10 fps, no more than that
[09:57] <alkisg> The GPU can decode 1920x1080 @ 60 fps, but it's not used by linux
[09:57] <alkisg> (well, without special players like omxplayer)
[10:18] <vlt> There's a video player in something like /opt/vc/src/hello_pi/ that plays full HD jst fine.
[10:18] <vlt> On raspbian, that is.
[10:20] <alkisg> omxplayer, yes, special players that know how to use the rpi GPU
[10:20] <alkisg> It's there in mate too
[10:20] <alkisg> The problem is that it's not integrated with the rest of the graphics stack (it plays only in overlay mode), and that it doesn't come as a library that other software like firefox could use
[10:21] <alkisg> So you can't use it to e.g. watch youtube videos on firefox. You can use it to watch youtube videos in kodi, but kodi also doesn't integrate well with X11 so it doesn't play in mate etc etc
[10:21] <alkisg> A mess. Ubuntu isn't yet ready for GPU acceleration like Android is.
[10:27] <ali1234> that's not really true
[10:28] <ali1234> hardware video decoding is available as a library with gstreamer
[10:28] <alkisg> Does it support rpi?
[10:28] <alkisg> It's also there with va-api, not only gstreamer
[10:28] <alkisg> The usual mess of independed implementation that no software can really use :)
[10:28] <alkisg> Firefox dumped gstreamer ages ago
[10:29] <ali1234> yeah, that's why it doesn't have accelerated video on rpi
[10:29] <alkisg> But gstreamer doesn't support rpi, does it?
[10:29] <ali1234> yes, of course it does
[10:29] <ali1234> it supports damn near everything
[10:29] <alkisg> Link?
[10:30] <alkisg> I don't know of any software that can use the rpi GPU to play in an x11 window
[10:30] <alkisg> Not gstreamer, nothing
[10:30] <alkisg> They can only do overlays
[10:30] <ali1234> of course, that's how the video hardware in rpi works
[10:31] <alkisg> So how would firefox use gstreamer if it cannot draw in an X11 window?
[10:31] <alkisg> Nice library then :)
[10:31] <ali1234> it would figure out where the window is and then create an overlay in that position
[10:31] <ali1234> just like how all hardware video players do it, in fact
[10:31] <alkisg> And how would it hide the windows above it?
[10:32] <ali1234> the overlay would be clipped
[10:32] <vlt> That works?
[10:32] <vlt> Sounds great.
[10:32] <ali1234> what works?
[10:33] <alkisg> So, you're claiming that if I run a gstreamer command that plays a video in rpi, i'll have clipping and everything?
[10:33] <ali1234> no
[10:33] <alkisg> (vlc can't do that either)
[10:33] <alkisg> What's missing then?
[10:33] <ali1234> a proper X11 driver actually :)
[10:33] <alkisg> Because with va-api I can surely do it, both with gstreamer and vlc
[10:33] <ali1234> the thing anholt is working on
[10:33] <alkisg> Ah :D
[10:33] <ali1234> well, it will be DRM
[10:33] <ali1234> so not X specific... more useful for wayland
[10:34] <ali1234> but the reason that the overlays can't get clipped to X11 windows is because of the shitty software X11 driver they use... not a problem with the concept of overlays, which have been used for video for like 30 years
[10:34] <alkisg> I've also heard that they're working on gl support. If those 2 things land, it'll be great.
[10:34] <ali1234> yeah that's all part of the same thing
[10:35] <ali1234> if you've ever tried to take a screen shot of a video player and got a pink window instead: overlays
[10:35] <alkisg> I still won't be able to use rpi because it needs e.g. 2 minutes to open a gmail tab, but I'll be able to use it as a media center at least :)
[10:35] <alkisg> Yes, it was blue back in windows 95 days
[10:35] <ali1234> if you ever moved the player window and the video lagged behind: overlays
[10:35] <alkisg> I do know about vga programming; made a diploma in it like 25 years ago :D
[10:36] <ali1234> the rpi is slow for sure
[10:36] <ali1234> it is not a desktop computer
[10:36] <ali1234> it makes a good embedded video player / control panel though
[10:37] <ali1234> the GPU is far more powerful than the CPU attached to it
[10:37] <alkisg> ali1234: at some point, flexiondotorg was trying to upload a patched kodi version in a ppa, but I cannot find it any longer; do you know if there's any way to run kodi inside x11/mate?
[10:37] <ali1234> not inside x11
[10:37] <ali1234> on the pi, when you run kodi, the entire UI is drawn in an overlay
[10:37] <alkisg> So for now, it's best to use something like libreelec, right?
[10:37] <ali1234> i would use one of the kodi specific distros, yes
[10:38] <alkisg> ty :)
[10:38] <ali1234> or just raspbian
[10:38] <alkisg> Raspbian? How does that handle kodi?
[10:38] <ali1234> dunno, but stuff generally works on raspbian because everyone uses it
[10:38] <ali1234> kodi can run at the same time as X but it has a funny bug
[10:38] <ali1234> they implement the screen saver / dimmer by making the UI transparent
[10:38] <alkisg> Ah, also I was wrong to specify "inside x11/mate", because running the whole ui in an overlay "above" x11 would be fine as well
[10:39] <ali1234> normally that lets through the black nothingness
[10:39] <ali1234> but if X is running, you see your X desktop instead
[10:39] <alkisg> Haha, funny :D
[10:40] <ali1234> i actually have kodi installed on my desktop and my android tablet but never tried it on pi
[10:41]  * alkisg searches for the patched vlc that can run atop x11...
[10:41] <alkisg> https://ubuntu-mate.org/blog/ubuntu-mate-xenial-raspberry-pi/ => Added OpemMAX IL hardware accelerated video playback to VLC. To enable hardware accelerated video playback go to Tools -> Preferences -> Video and select OpenMax IL.
[10:42] <alkisg> Eh cool, it's already there, I can use that
[10:44] <alkisg> ali1234: do you have a rough idea about when to expect a proper X11 driver? Like, 6 months, or a couple of years?
[10:44] <ali1234> i would say more like a couple of years
[10:44] <alkisg> ty :)
[10:45] <ali1234> its one of those things that always looks like it will be done in a couple of months ut never actually is
[10:45] <ali1234> like wayland, unity 8, app sandboxing etc
[10:45] <alkisg> Haha, good examples
[10:46] <alkisg> I really wonder how google managed to ship android in only a few years, with many such things already implemented
[10:46] <alkisg> How many programmers were they able to hire and coordinate...
[10:47] <ali1234> the answer to that is they hired everyone who worked on beos
[10:48] <ali1234> (nearly)
[10:48] <alkisg> Aaaaah didn't know that
[10:48] <ali1234> and early android is full of beos stuff
[10:48] <alkisg> That makes a lot of sense
[10:48] <ali1234> also android was developed by a startup which google bought
[10:49] <ali1234> i dont remember if the beos people worked for that startup, or if google brought them in
[13:10] <Guest49356> hi.i have some issue with laptop fan and heating. after all tweaking in here (http://askubuntu.com/questions/828967/limit-total-cpu-usage-using-tlp) no result!
[13:11] <Guest49356> just with limiting cpu usage in tlp to 30% its gets better result.
[13:14] <Guest49356> any idea?
[13:27] <ubuntu-mate> hello
[13:31] <ubuntu-mate> I'm battling here to make the partition tables on GPT to work. If anybody has a useful link it would be most appreciated
[13:38] <ouroumov> hello ubuntu-mate
[13:40] <ouroumov> ubuntu-mate, can you please describe what issue you're experiencing?
[13:42] <ubuntu-mate> Hello ouroumov I am trying to change the partition table from MBR to GPT in order to run boot-repair and be able to boot normally
[13:42] <ouroumov> Is this a dual boot setup?
[13:44] <ubuntu-mate> it probably was, it's my pc at work. Now is only linux
[13:47] <ouroumov> I think you should just redo the install process in that case. Unless you have specific partitioning requirement just use the "erase disk and install" option
[13:49] <ubuntu-mate> Do you think that formating the /dev/sda fully making a fresh install would help ?
[13:50] <ouroumov> Yes, you did use manual partitioning right?
[13:51] <ubuntu-mate> I haven't yet. I just used the computer with the system there was when I started my contract. ubuntu 14.04. Are there any particular things to select in the manual partitionning ?
[13:56] <alkisg> ubuntu-mate: do you have data inside the disk that you need to keep?
[13:58] <ubuntu-mate> nope.
[14:00] <ubuntu-mate> There are 2 other hard drives, one which has another boot sector, but it seems not to be detected by the BIOS nor EFI when booting
[14:01] <alkisg> Then you can run gparted and select "create new partition table", "msdos format"
[14:02] <ubuntu-mate> the installer will automatically create the booting sector for BIOS or EFI ?
[14:02] <alkisg> Are you booted in bios or in legacy mode?
[14:02] <alkisg> ls /sys/firmware/efi
[14:02] <alkisg> *or in uefi, sorry
[14:03] <ubuntu-mate> Lastly, At which point will I be able to chose between GPT or MBR  ? -- I boot on BIOS now, the ubuntu forum sais that EFI is better
[14:03] <alkisg> Leave if to bios, because not many people or tools know how to fix uefi problems now :)
[14:04] <alkisg> If you booted in uefi, you should use gpt
[14:04] <alkisg> If you booted in bios, then mbr
[14:04] <alkisg> You can choose it from the gparted menu I said
[14:04] <ubuntu-mate> I will then. in /sys/firmware/efi there is some stuff there
[14:04] <alkisg> Then you booted in uefi mode
[14:05] <alkisg> So, use gparted to format it to gpt
[14:05] <ubuntu-mate> Alright. I had a problem with MBR, it didn't allowed me to chmod the files. That was the root of all this. Will I be able to chmod ?
[14:05] <alkisg> MBR and GPT are not related to chmod at all
[14:05] <alkisg> You are wrong to assume taht
[14:05] <alkisg> *that
[14:06] <ubuntu-mate> Oh, well. Trying is how we learn. That was the answer I found on an ubuntu forum.
[14:08] <ubuntu-mate> That's how we learn stuff ^_^ -- It seems that the GPT table is corrupt
[14:09] <alkisg> But you also need to follow some instructions
[14:09] <alkisg> E.g. I said "create new partition table", how can it be corrupt now? :D
[14:09] <alkisg> Trust gparted and parted. Don't trust other software. :D
[14:11] <ubuntu-mate> Alright alkisg. I'm on it now
[14:12] <alkisg> Also, it's nice to have a nickname of your own in irc, so that you can continue chatting with others some other day, and they remember your setup etc
[14:12] <alkisg> So, type /nick yourname
[14:13] <ubuntu-mate> right !! I hadn't noticed, i'm lhtd
[14:16] <lhtd> I have a question, how does the system decides weather devices are a,b,c, in /dev/sdx ?
[14:17] <alkisg> It's not deterministic, that's why UUIDs were implemented
[14:18] <lhtd> Alright. I think I'll need to clean all HDs of this computer and start a real fresh install.
[14:19] <lhtd> It's annoying that the IT just drop all aid when on any unix/linux system. They don't even format them
[14:27] <lhtd> 2 of the 3 HD have been formated, but gparted still says: The backup GPT table is corrupt
[14:32] <alkisg> When you say formatted, do you mean "device => create new partition table" from gparted?
[14:33] <alkisg> First you create a new partition table, then you format the partitions
[14:33] <alkisg> So you can't say "i formatted a partition table", it's wrong
[14:33] <lhtd> Yes, I did that for /dev/sda and for /dev/sdc. one at a time
[14:33] <alkisg> What's the output of: sudo parted -l | nc termbin.com 9999
[14:34] <lhtd> Error: The backup GPT table is corrupt, but the primary appears OK, so that will be used.
[14:35] <lhtd> http://termbin.com/umr7
[14:35] <lhtd> and that's it
[14:36] <alkisg> I can't believe that you create a new partition table from gparted and it still says it's corrupted after doing that
[14:36] <alkisg> Anyway, ok, try this: sudo dd if=/dev/zero of=/dev/sda bs=512 count=1
[14:36] <lhtd> I had never had this much trouble with partition tables. I feel too noob
[14:36] <alkisg> This completely clears the partition table; then re-created it with gparted and see if the error goes away
[14:40] <lhtd> I did the dd command, and then re-created it with gparted, then quited gparted. When I open again gparted the same error will still pop
[14:41] <alkisg> ok, now try with sudo gdisk /dev/sda
[14:41] <alkisg> And use its menus to clear the backup gpt too
[14:41] <lhtd> I tried to install ubuntu-mate, it prevented me that it would be installed in UEFI. Maybe i need to boot and start on BIOS
[14:41] <lhtd> Ok, on it alkisg
[14:46] <lhtd> Found invalid GPT and valid MBR; converting MBR to GPT format in memory
[14:48] <alkisg> Select to clear them all
[14:50] <lhtd> done
[14:50] <lhtd> GPT and MBR have been cleared
[14:52] <lhtd> I'm dying.. I opened gparted again and it tells me that the GPT table is still corrupt...
[14:53] <lhtd> I'm gonna reboot. I'll be back shortly
[15:02] <lhtd> back
[15:02] <ouroumov> wb
[15:03] <lhtd> thnx
[15:06] <gelvezz23> hola
[15:06] <gelvezz23> a todos
[15:06] <gelvezz23> alguien sabe como quitar Escritura de una usb
[15:06] <ouroumov> !es | gelvezz23
[15:07] <gelvezz23> thank you
[15:08] <lhtd> well, I rebooted on BIOS. Gparted still sais that the backup GPT table is corrupt. I'm creating a new primary partition in ext4
[15:09] <ouroumov> lhtd, may I ask why you don't just boot the USB into install mode and proceed?
[15:10] <ouroumov> lhtd, with "Erase disk and install" as your choice of partitioning, I don't think you'll have any problems.
[15:11] <lhtd> Very smart ouroumov I will, I'm trying to understand this a little bit, I've never been confronted to this. And I needed to boot on BIOS, some minutes ago i was on UEFI, so the boot was warning me about some incompatibilities while preparing the installaiton
[15:11] <lhtd> ouroumov, I'll finish the formatting the other HD, and i'll go for the install.
[15:18] <lhtd> I feel old. Some years ago we would make Install parties with my friends
[15:19] <ouroumov> That's still a thing
[15:19] <lhtd> with beers and pizza ?
[15:20] <lhtd> Maybe it's just my friends who don't do it anymore
[15:20] <ouroumov> Of course.
[15:20] <lhtd> That's fun !
[15:22] <pvl1> hey all, outside of this: https://ubuntu-mate.community/t/move-to-copy-to-in-caja/330/6 is there a way to add a destination to the caja copy-to right click menu list
[15:22] <vlt> alkisg: Hi!
[15:23] <vlt> I did some testing on a fresh Ubuntu 16.04 machine.
[15:24] <alkisg> vlt: and?
[15:24] <vlt> The Alt+Tab problem happens with marco. After switching within the same Xvnc session to openbox, for example, Alt+Tab works just fine.
[15:24] <alkisg> I'm using marco and I don't have the alt+tab problem
[15:24] <alkisg> Did you try another vnc like I proposed?
[15:24] <vlt> hmmm
[15:25] <alkisg> For example, now I'm remotely connected with x11vnc/xvnc4viewer
[15:25] <alkisg> I can alt+tab just fine
[15:25] <alkisg> And i'm running marco
[15:26] <vlt> I tested several vncviewers. All the same.
[15:26] <vlt> Can you help me change something on the server side?
[15:26] <alkisg> How?
[15:27] <vlt> What other than xvncserver should I run to test that?
[15:27] <vlt> -x
[15:27] <alkisg> I did write you exact commands before :)
[15:27] <alkisg> pc1: xvnc4viewer -listen
[15:28] <alkisg> pc2: x11vnc -connect pc1
[15:28] <vlt> alkisg: I know, sorry.
[15:28] <alkisg> f8 for full screen, then alt+tab
[15:28] <vlt> I didn't unserstand them fully.
[15:28] <alkisg> It's that easy
[15:28] <vlt> I'll do exactly that now.
[15:28] <alkisg> You need xvnc4viewer in pc1, and x11vnc in pc2
[15:28] <alkisg> pc1 is the "server"
[15:30] <vlt> The listening viewer is listening but the x11vnc command fails.
[15:30] <vlt> *** x11vnc was unable to open the X DISPLAY: ":0", it cannot continue.
[15:31] <alkisg> Are you running it from within X?
[15:31] <alkisg> Don't run it from ssh or vt1...
[15:31] <vlt> alkisg: No, there's no X.
[15:31] <alkisg> OK, test on a machin with X
[15:31] <vlt> It's "just" a headless server,.
[15:31] <alkisg> Test it on another pc then
[15:32] <alkisg> You want to test a software bug now, not solve your specific setup issue
[15:32] <alkisg> You'll verify that it's a problem with xvnc+marco, and not with just marco, so maybe a xvnc problem
[15:32] <alkisg> So that you'll know where to report the bug
[15:33] <alkisg> You can even do that between ltsp clients, take the screen of fatclient2 while working on fatclient1
[15:33] <vlt> Yeah, I am trying to find a real machine here ;)
[15:35]  * vlt installs ltsp-server on the 16.04 testing machine, builds an image and then points one of the clients to boot from that.
[15:35] <vlt> brb
[16:08] <lhtd> The menu to prepare the install for mate from a USBkey is quite slow :-S The install is not yet started
[16:11] <Akuli> lhtd, are you making the usb stick or have you booted from it already?
[16:11] <lhtd> i'm on the live-boot
[16:12] <Akuli> how much ram does your computer have?
[16:12] <lhtd> 64Gb
[16:13] <Akuli> that's 32 times more than i have, so shouldn't be a problem
[16:13] <pvl1> god the klondike bars id give for that much ram
[16:13] <Akuli> maybe ubuntu doesn't like your graphics card?
[16:13] <alkisg> Maybe he means the usb stick size :)
[16:13] <pvl1> ooh
[16:13] <Akuli> lol
[16:13] <Akuli> makes sense
[16:13] <pvl1> blah ive tried swap on a USB
[16:13] <pvl1> usb3 isnt tooo bad
[16:14] <lhtd> that's also 32x more than I have at home
[16:15] <lhtd> It´s probably that. It took it 10min to go from the ¨Do you want to install updates && third party software¨ to the next one
[16:15] <Akuli> that's not nice
[16:16] <Akuli> is it possible to check for better drivers before installing? i don't remember
[16:16] <lhtd> it´s friday, if I had known i´d called to vet delivered some pizzas to pass the time
[16:16] <lhtd> r/vet/get/
[16:18] <ouroumov_> I've seen that step take a while as well
[16:18] <ouroumov_> Not sure what's causing it.
[16:19] <lhtd> maybe it´s the closure of remote connection :-P
[16:23] <lhtd> well, it forced me to restart after the install, but Here it is all rolling
[16:24] <Akuli> is it still slow?
[16:25] <lhtd> so fat it seems quite reactive
[16:25] <lhtd> even typing is quite quick
[16:26] <lhtd> is there a package manager included or is it all apt-get ?
[16:28] <Akuli> well, apt-get is a package manager :) i believe the GUI thing is called software boutique nowadays
[16:29] <lhtd> That is so français
[16:31] <Akuli> yeah i would probably guess it's a mint thing if i didn't know that
[16:32] <lhtd> I used to have mint at home. i really liked XFCE, I discovered mate on my previous position
[16:33] <vlt> alkisg: back
[16:34] <vlt> Test setup: thin client running Ubuntu 16.04, plain marco and xterms.
[16:34] <vlt> x11vnc
[16:35] <vlt> Alt+Tab works there like you already observed.
[16:36] <vlt> So, x11vnc+marco OK, x11vnc+openbox OK, vnc4server+openbox OK, vnc4server+marco FAIL
[16:37] <lhtd> darn... I just noticed I just lost my .bashrc and other config files....
[16:37]  * lhtd 's brain is already gone on a week-end
[16:42] <lhtd> I will have to re-install a big bunch of software to do bioinformatics. Do you have an advise to try and install all those things in a single directory, available for all users ?
[16:51] <Akuli> is it all from apt-get?
[16:52] <Akuli> if you have a list of packages to install it's pretty easy to install things that way
[16:52] <lhtd> nope, I'll make a install.sh with all the apt-get stuff, but I need some softwares which either I need to compile myself, either to make them executables.
[16:52] <lhtd> I just want to keep a healthy system
[16:53] <Akuli> usually i install dependencies with apt-get build-dep when i compile things
[16:53] <vlt> Can someone confirm Alt+Tab not working for marco in a vnc4server session on Ubuntu 16.04?
[16:53] <lhtd> (if i get some free time i'll try to get involved in making ppa repositories for some bioinformatics software)
[16:59] <lhtd> O_O !!! after the re-install all the chmod that I had done do were effective.
[17:02] <Akuli> lhtd, yeah, the usb session is all temporary
[17:02] <Akuli> all in your 64gb ram :)
[17:04] <lhtd> It's my lab's computer, but it's fun. there are 24 proc
[17:04] <lhtd> I've never worked on a such powerful local machine !
[17:05] <lhtd> Akuli, i'll take a deeper look ti apt-get build-dep, thanks !
[17:25] <enrique> Well, guys, it's getting late. Thank you very much for the help. I'll probably be here on monday. Enjoy the Week end :-)
[17:42] <calamari> hi. something broke recently where my system no longer sets correct primary monitor. Settings claims it's right, but it's not. So, I have to set the primary to the other monitor, then set it back to the correct monitor. Is there a bug opened for this?
[18:33] <juupeli> evening
[19:59] <jeremy> gday
[20:24] <sparker_> running mate in a windows environment is about the best thing ever...
[20:33] <Eightynine> Hi. Can I install Ubuntu MATE on PC with Skylake processor?
[20:34] <alkisg> Yes
[20:38] <Eightynine> And it will boot with UEFI without any problems?
