logicalHi, today when I turned on my pc in the pictures folder all images have some xmp file next to it, here is a screenshot http://pix.toile-libre.org/upload/original/1472644269.png11:52
rahtgazseems like something a picture manager would do. Have you installed anything from Adobe lately?11:59
rahtgazcheck this list for possible applications doing that stupid thing to your collection: https://en.wikipedia.org/wiki/Extensible_Metadata_Platform#Support_and_acceptance12:00
logicalemm no i didnt install anything12:01
rahtgazwell, you can safely delete those files, of course. Just keep an eye for a similar incident on the future and try to remember what you used that may have generated those files.12:04
rahtgazit's got something to do with photo managers or images in general12:04
mate|84147anyone about?12:18
mate|84147Ubuntu Mate 16.04  Running 1.12.1, Trying to make mouse cursor larger. Traditional gnome edits in org.gnome.desktop.interface do not seem to work12:23
* SuperEngineer resists temptation to suggest using binoculars ;-)12:39
SuperEngineer...7 instead recommends looking in accesibilty options,; perhaps there may be something there?12:44

mate|84147Tint... same boat as you.13:15
TintomaticI can put any picture up, but not a color or gradient. I see this o both Mate 1.12 and 1.14.13:16
Tintomaticis it a known problem?13:17
SuperEngineerI don't know if it's im/possible.  I do know that that taking a piccy of a solid colour & setting that piccy as your background seems plausible.13:17
TintomaticSuperE: yeah, I might go that route.13:18

RFlemingGreetings and other salutations!16:04
oswriterSame to you, RFleming16:06
RFlemingHow goes it?16:06
* RFleming hopes he doesn't get ticketed by the 'off-topic' police.16:06
ouroumovIt's loosely enforced here.16:10
ouroumovEspecially when there's no active help requests16:10
oswriterif we want to stay on-topic i have been testing the 16.10 beta.. so far the computer hasn't exploded, so that's a good sign.16:12
ouroumovThat's true. Good for you then. :D16:12
ouroumovActually Wimpy's described 16.10 as the most boring releases ever16:13
oswriterWimpy is always the master of the undersell lol16:14
ouroumovSo they're unlikely to cause unscheduled rapid combustions16:14
RFlemingWhat all is it?  The move to 1.14 and better gtk3 support?16:14
oswriteri noticed it does look a little sharper, i assume that's the gtk316:14
ouroumovRFleming, no, actually it's not GTK3 support, it's GTK3 transition, full on.16:14
Akulii wonder whats going to happen to all the awesome gtk 2 applications i ise16:15
Akuliuse16:15
RFlemingoswriter, the only thing I care about (MATE wise) are separate panel icon support, so I can have monochrome icons in my panel :)16:15
oswriterRFleming, I hear ya, I like a good monochrome icon set myself16:15
RFlemingI like pretty colour icons in caja, but I'd like all notification icons to look the same :)16:16
RFlemingbut I guess that's gnome2 style :)16:16
RFlemingis mir rolling out in 16.10?16:19
RFlemingor has it been pushed back again?16:19
oswriteri hadn't heard anything about mir in 16.1016:20
oswriteri know fedora is shipping wayland by default in its next release16:21
RFlemingHas anyone else noticed that when Canonical goes away from what everyone else does... they end up going back to what everyone else does?16:23
RFlemingupstart comes to mind16:23
RFlemingI understand they want a unified ds for cross-platform compatibility... but could that not have been achieved with wayland?16:24
* RFleming shrugs16:25
RFlemingSorry... should not talk politics in chat16:25
RFleming:)16:25
ouroumovIt's on-topic, and there's no "don't say bad stuff against canonical" rule.16:27
RFlemingouroumov: true, but it's one of those polarizing topics.16:27
RFlemingSo for giggles yesterday, I tried to upgrade an old production server... running Intrepid :)16:29
RFlemingI wanted to see how far I could get with it still functioning.16:29
oswriterHow did it go?16:30
RFlemingI went Intrepid->Jaunty->Karmic->Lucid ... then the wheels fell off16:30
RFlemingI could not get do-release-upgrade to go from lucid to precise16:30
ouroumovhaha16:30
oswriterheh16:30
RFlemingI've never had apt prompt me before to answer 'Yes, do as I say!'16:31
RFlemingit was fun though16:32
RFlemingI think what made it go as far as it did, was the fact it's an old Ubuntu Server install, with minimal modifications done to it.  It was running CVS with the xinetd superserver16:33
AkuliRFleming, getting apt to ask you do that is easy16:56
Akulijust remove some package that your system absolutely needs to run, like dpkg or apt itself16:56
Akuli(no, don't do that)16:56
RFleminglol16:57
Akulii do prefer aptitude though16:57
Akuliits just awesome in many ways16:57
RFlemingYeah...16:58
Akuliperfect translations to finnish, curses interface, built-in minesweeper...16:58
RFleminggcc needs minesweeper :)16:58
Akuliit doesn't moo, but it does have an easter egg :)16:58
Akulii mean aptitude16:59
RFlemingI would have beat it when I was compiling linux under Gentoo on a dual core AMD Athlon 64 X2 :)17:00
* RFleming is feeding cats as an easter egg on my Android 7 phone :)17:01
RFlemingan interesting easter egg in Nougat17:02
RFlemingone of these days I should just alias apt to aptitude17:04
RFlemingOh god... I need eye-bleach!17:05

RFlemingI can't believe we made web pages look like that17:05
RFlemingthe horror!17:06
blinkoHi, I want to install ubuntu mate on an old laptop that comes with two hard drives. I would like to configure the system to use lvm 2 volume groups. I can't do it via the gui is there a way to install everything manually from the terminal?17:17
Akuliyou can do anything from the terminal you can do from the gui17:22
Akuliyou could use this with ubuntu https://www.debian.org/releases/stable/i386/apds03.html.en17:23
Akulibut its going to be difficult17:23
Akuliso i'd just recommend getting an ubuntu mini.iso and using that17:23
Akulihttps://help.ubuntu.com/community/Installation/MinimalCD17:23
blinkook, thanks.17:24
blinkoI'll give it a shot17:24
Akuliafter installing with your mini.iso you want to change your /etc/apt/sources.list to ubuntu mate stuff17:24
Akuliand run a sudo apt-get dist-upgrade17:24
Akulithen you should be able to install ubuntu-mate-desktop and it should work17:24
blinkoAkuli: Thanks :)17:25
Akuliif you have any trouble with that ask me :)17:26
Akulii would actually recommend you do that with 14.04 if the computer is old17:29
Akuli14.04 will be supported until 201917:29
blinkoIt is not that old, my cousin got a new computer and he says that windows is slow so I am trying to get him to try linux :).17:30
Akulione problem you might run into is that the old computer probably doesn't boot from a usb stick17:31
Akulibut thats easy to work around17:31
blinkoIt does I already tried it17:31
Akulioh :) there you go17:31
Akuliits not that old then17:31
RFlemingCurious question.  Why would anyone still use LVM when filesystems like btrfs and zfs are available?18:20
RFlemingwasn't LVM kinda a stop-gap type measure to offer features missing in the EXT series of filesystems?18:21
RFleming... don't get me wrong, I'm still using EXT4 without LVM18:21
alkisgbtrfs has a lot of issues, it's not really ready for wide use18:26
Akulii don't really care about what filesystem i run :D18:27
Akuliits ext4 without lvm18:27
alkisgAh, you haven't yet lost 10 years of valueable data, that's why :D18:27
Akulii don't really have anything valuable18:28
Akuliall i care about is my programming projects and they're all in github and cloned on many computers18:29
RFlemingalkisg: if you've lost 10 years of valuable data, you haven't been doing backups18:30
RFlemingand if you've only had one backup source... well :)18:31
allanVikingI've been trying to google this to no avail, but is it possible to switch my stock ubuntu 16.04 LTS running mate-desktop into Ubuntu Mate 16.10 beta? I have everything mounted via chroot in livecd atm, because I totally destroyed everything whilst trying to upgrade from 14.04->16.04. I dont want to do a fresh install, as my mate is very heavily con18:34
allanVikingfigured and I have hundreds of apps installed18:34
allanVikingright now it doesnt even boot past initramfs, so im hoping to nail 2 flies with 1 stone so to speak: by upgrading to sth I've wanted for a while and during the process hopefully fixing my system18:36
alkisgRFleming: yes, when that happened I couldn't afford a second hard disk :)18:36
RFlemingallanViking: the only thing I can think of is do-release-upgrade -d18:36
RFlemingbut has 16.10 gone beta?  Last I knew it was still Alpha 218:37
allanVikingsorry, I meant alpha18:37
RFlemingI don't believe do-release-upgrade -d upgrades to alpha releases18:37
allanVikingit seems stable enough for me, I've used alphas in the past18:37
allanVikingit doesnt:18:37
allanViking# do-release-upgrade -d18:37
allanVikingChecking for a new Ubuntu release18:37
allanVikingNo new release found18:37
RFlemingallanViking: you can get the alpha iso and boot off of it and do an upgrade18:37
RFlemingI think the alpha installer will allow that18:38
allanVikingRFleming: will it keep all my current apps and settings for mate?18:38
RFlemingallanViking: it should18:38
RFlemingno promises though.  It is alpha :)18:38
allanVikinghaha :D18:38
RFlemingallanViking: you have a good backup?18:38
allanVikingmaybe its better to upgrade my stock 16.04 into Ubuntu Mate 16.04 with the iso on then upgrade that into alpha?18:39
RFlemingUhh... maybe18:39
RFlemingI hate playing with different WMs though... it always screws something up18:39
allanVikingI only need mate anyways18:40
allanVikingI've been using it since 1.618:40
RFlemingyou poor thing you :)18:40
allanViking:D18:40
allanVikingbut installing ubuntu-mate-desktop into a stock ubuntu will not make it into 100% the same as Ubuntu Mate ?18:40
RFlemingallanViking: no, it won't18:40
allanVikingI want everything to be GTK3, because I have HiDPI screens18:40
RFlemingallanViking: oooh... you're going to have a hard time with that then :)18:41
allanVikingI already resolved it it with xrandr scripts - I have tons of monitors with tens of combinations18:41
allanVikingno way any display app can manage that18:41
allanVikinghopefully it will stay working18:41
RFlemingyou may need a tiling wm :)18:42
allanVikingI've resolved that aswell, with quicktile18:42
allanVikingthe HiDPI screen is just 15.4" though18:42
allanVikingbut I tile everything on my 3 screens18:42
RFlemingwhat sense is that?18:42
RFlemingwhy would anyone make a hidpi screen that small?18:42
allanVikingbusiness class laptop18:43
RFlemingit's like making a 24" TV 4K18:43
allanVikingi think 24" should be atleast 4K :D18:43
RFlemingit must be a Dell18:43
allanVikingI dont understand why people dont look at pixel densitu18:43
allanVikingnope, Thinkpad all the way18:43
allanVikingIPS 3K panel18:44
allanVikingall other laptop panels look like **** compared to this18:44
allanVikingbut my external monitors are old LCD's ~23", not hiDpi - configuring that was tricky at first18:44
RFlemingallanViking: going back to your question... I'd make a thorough backup of your system, and try to upgrade using the Mate 16.04 iso18:46
allanVikingRFleming: I am doing it as we speak18:46
allanVikinghopefully I dont loose my mate-panel settings18:46
RFlemingif it doesn't work out, you can just reinstall Ubuntu 16.04 and restore overtop18:46
allanVikingI'l try the 16.10 alpha2 upgrade route first18:47
allanVikingits not like its gonna break anything further on a broken system :D18:47
RFlemingthis is true18:47
RFlemingOK... back to fixing vulnerabilities18:47
allanVikingbacking up etc should be enough to keep my settings? I have my files on other disks and partitions18:47
RFlemingtoday it's mitigating a kernel bug.18:48
allanVikingthank you :)18:48
allanVikingI am hoping to one day contribute code to Mate aswell18:49
RFlemingallanViking: it depends on how you're backing up.  I have a shell script that makes a tar.gzip archive of everything on my system with the exception of /dev /proc and /sys... and a couple of other locatinos18:49
RFlemingif my system ever blows up, I install fresh, and extract over top the newly installed system and reboot.18:50
allanVikingI have home var and opt elsewhere and in the past I have installed a new system and then moved home and opt back, merging etc18:50
RFlemingallanViking: why move them?  Use bind in fstab and bind their locations to known ones18:51
RFleming(assuming they're on different disks)18:51
makkaHello! bit of a noob question i guess, but whats the best wau18:51
allanVikingI do use bind actually, I was just simplifying :p18:51
RFlemingWelcome makka!18:51
makkaway of SSH into the PI using mate?18:52
makkaHello o/18:52
RFlemingmakka: from Windows, or linux?18:52
makkalinux18:52
makkaubuntu to be exact18:52
Akulishould be pretty easy18:52
RFlemingssh pi@<ipaddress>18:52
Akuliof course, you want to install openssh-server on the pi first18:52
makkai read you needed to install a ssh client?18:52
Akuliyour ubuntu will tell you if you haven't installed it18:53
RFlemingmakka: on the Pi, you need an SSH server.  openssh-server to be exact18:53
Akuliyou also need to add your pi to /etc/hosts on the ubuntu18:53
makkaright, ill crack open a term and give it a shot18:53
Akulisounds like a lot of work, but it really is not18:53
RFlemingAny sys admins in here... https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-5696.  You'll want to patch that up18:54
ubottunet/ipv4/tcp_input.c in the Linux kernel before 4.7 does not properly determine the rate of challenge ACK segments, which makes it easier for man-in-the-middle attackers to hijack TCP sessions via a blind in-window attack. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-5696)18:54
Akulimakka, actually you don't need to have the pi in /etc/hosts if you type out its ip18:54
Akuliyou can find that out by running ifconfig on the pi18:54
makkaopenssh-client is already the newest version (1:7.2p2-4).18:55
makkacomes preinstalled i see18:55
makkaderp, thats the client ^^18:56
makkaguess they both do actually18:57
makkaah awesome, that was much simpler that it looked on reading, Thanks guys!19:00
makkacan i use the pi's external ip?19:01
Akulimakka, i'd use the one the network is using19:01
Akulirun /sbin/ifconfig on the pi to find out19:01
makkaif for instance i wanted to use it from work?19:01
Akulii guess you can, i've never succeeded with that though19:02
Akuliyou also need to allow ssh through your firewall if you use one19:02
Akulie.g. sudo ufw allow ssh19:02
makkacan only see an internal here, suspose i can use a website to find my ip, but that19:03
makkathat's dynamic right?19:03
makkaheh, im sure ill figure it out, afterall i was doing this stuff 10 years ago as a kid with RS servers and noip.org DNS ^^19:04
makkathanks again for the help guys!19:04
blinkoHello, is there another way to install ubuntu mate with custom partitioning (raid / lvm) other than doing https://help.ubuntu.com/lts/installation-guide/amd64/apds04.html ? I am afraid the end result will differ too much from the GUI stuff.19:12
blinkoIs there a script or code I can look into? Thanks19:13
RFlemingblinko: I think the only way you'll be able to do this custom type of install, is to partition manually from the live cd, and then when you go to install chose the 'something else' option and just use the setup you've already created19:44
RFlemingSo basically, do what you need to from the live cd, then run the installer19:45

tioxI've already done it, but is there any reason why someone would need to add the PPA for UM's MATE 1.14 GTK3 aside from GTK3?21:55
ouroumovStill haven't found one21:59
tioxlol22:00
tioxWell, that's sort of what I wanted to know; Maybe Martin knows since he continues to build for it.22:01
ouroumovI think there's better hi-dpi support22:01
tioxHe has to be building the GTK3 MATE packages for some reason, right?22:01
ouroumovBut it's of limited interest for me because max res 1920x108022:01
tioxThat could probably be it.22:01
tioxI was hoping it would allow for truly transparent panels like on XFCE but nope.22:02
ouroumovWhat does "Truly Transparent" means? :o22:02
tioxEither with or without the PPA, the alpha on panels is faked unless you force the entire panel to have alpha, which would affect all parts of the panel rather than the background colour.22:03
tioxIf you make any panel use alpha with background colour, you don't see the content underneath the panel, but it still uses a portion of your desktop background.22:04
tioxNow, on DockX, Plank, and xfce4-panel, you can use alpha and see content underneath it.22:04
ouroumovBy faked you mean what's behind is redraw?22:05
tioxThat's what I consider "True transparency" or "True alpha"; being able to see the content underneath. It's like how some terminal emulators do with fakeargb; You see the desktop background when there is nothing else opened, but the moment there is another window under it you see the desktop background still instead of the content underneath.22:05
ouroumovoh22:06
tioxAlso, I guess it's redrawn, whatever you want to call it.22:06
tioxIt looks crap and dated af.22:06
tioxI should provide another example some time with a Ubuntu MATE live session and install xfce4-panel just to show what I am talking about. Backport compiz, enable screensaver, make the cube rotate and take a screencap.22:08
tiox(And it probably occurs in COmpton too but the cube's the easiest way I could show what I am on about.)22:08
tioxOr it could be a Compiz 0.8-specific problem, like what I encountered with the dock panel robint99 maintains.22:09
tioxs/dock/applet22:09
tioxGrgh.22:09
tioxDock applet, rather, not dock panel lol22:10
ouroumovNo actually you're right.22:13
ouroumovIcons behind panels get cut.22:14
ouroumovIn Compton22:14
ouroumovIt's only visible with an autohiding panel22:14
tioxWait what?22:14
ouroumovBecause when it's not autohide, you can't put the icon half through the panel22:14
tioxSo true alpha occurs ONLY with autohide?22:15
tioxThat seems like bullocks to me.22:15
ouroumovWhat? No22:15
ouroumovI'm saying you're right, it looks fake since the icon gets but by the background22:15
ouroumovSee https://i.imgur.com/uWlCR4S.png22:17
oswriterSo I'm using 16.10 Beta and trying to setup Keyboard Shortcuts. Everything works fine except when I try to set a shortcut for Caja. It simply doesn't work. I noticed this same issue in 16.04 but I worked around it by typing the full command path instead of just the command. But in 16.10 it doesn't work either way.23:00
