[02:20] <edgar__> Good night everyone!
[02:20] <edgar__> starting today to use Ubuntu Mate 17.10!
[02:46] <EldonMcGuinness> I was thinking of installing mate on a lab of old computers, any gotchas I should be aware of? I'm familiar with Gnome and KDE, but not used Mate personally.
[02:46] <EldonMcGuinness> I'm loading it into a VM as we speak so I can try it out.
[02:49] <White_Light> what version of mate, and are you mainly talking about hardware support gotchas?
[02:50] <EldonMcGuinness> Well anything really, I've read it seems to work well on devices that do not have the horsepower for 3d acceleration is that true?
[02:50] <White_Light> yeah it does fine with or without 3D accel at least the desktop does
[02:50] <EldonMcGuinness> I'm was thinking of going with the ubuntu mate 16.04 LTS
[02:51] <EldonMcGuinness> but I'm ok with using something else if it offers better support for older devices
[02:51] <White_Light> what will the lab computers be used for and what specs roughly?
[02:51] <EldonMcGuinness> They will mainly be used by elementary kids to go on learning websites
[02:51] <EldonMcGuinness> Khanacademy, lexiacore5, etc.
[02:52] <EldonMcGuinness> The most intensive part of the sites is generally the flash, I know...I know, on Lexia's site.
[02:53] <EldonMcGuinness> They are all old Dell optiplex devices. Generally with 1GB of ram and more than enough HDD space for the installs
[02:53] <EldonMcGuinness> I think they are all 1.8GHz or higher
[02:53] <EldonMcGuinness> but certainly nothing lower than 1Ghz
[02:54] <EldonMcGuinness> I'm trying to get them to replace the hdds in them as majority of them are showing smart pre-fail messages, with any luck I can get them to order ssds for them
[02:54] <White_Light> it's worth a shot, I think it's fairly safe to say that web browsing will be the true test of the machines and not the Desktop Environment
[02:56] <EldonMcGuinness> yea I'd imagine the flash will, as it usually is, be the main issue
[02:56] <EldonMcGuinness> I'm thinking chrome might fare better than firefox on them
[02:57] <EldonMcGuinness> How well does it function without the 3d acceleration?
[02:58] <White_Light> I'm not sure, I've never really run flash on a web browser in recent years let alone without 3D acceleration on the machine I'm using
[02:58] <White_Light> I think it's best to just test it out, also see if you can pre-download the videos and play them locally
[02:58] <White_Light> if possible
[03:00] <EldonMcGuinness> yea, I'll give that a go
[03:00] <EldonMcGuinness> I'll be on the campus tomorrow and I'm gonna install a couple diff flavours, but I'm thinking mate is going to win
[03:00] <EldonMcGuinness> Though it does not help to have spinning disks that are prefail lol
[03:02] <White_Light> yeah that will be an impediment for any OS unless you plan to run something off a usb stick
[03:02] <White_Light> hardware support for Dell Optiplexes is generally perfect by the way
[03:02] <EldonMcGuinness> thanks for the info, yea, I'm just hoping I can get them to spring for new hdd
[03:03] <EldonMcGuinness> If I can get flash to work ok tomorrow on the boxes as they are then I'm sure sdd will help if nothing at least a little :P
[03:03] <White_Light> only issue I could see is that sometimes the BIOS has the disk set to "RAID" which is a terrible way for Windows to not bind its native disk drivers and instead use intel rapid store
[03:03] <White_Light> use AHCI instead
[03:03] <EldonMcGuinness> indeed and cheers
[03:03] <White_Light> good luck
[03:09] <EldonMcGuinness> Thanks!
[03:12] <EldonMcGuinness> Is there a way to do an automated install by any chance? I'm googling now but figured I'd ask.
[03:13] <White_Light> Given your use case, I'd look into creating a kickstart file
[03:13] <White_Light> I haven't created one for Ubuntu (just CentOS/RHEL), but I believe Ubuntu supports kickstart installations
[03:14] <EldonMcGuinness> cheers again
[03:14] <White_Light> http://gyk.lt/ubuntu-14-04-desktop-unattended-installation/
[03:14] <White_Light> this is for 14.04, but it should hopefully be pretty similar for 16.04
[03:15] <White_Light> http://gyk.lt/ubuntu-16-04-desktop-unattended-installation/
[03:16] <White_Light> instead of "ubuntu-desktop" under "Additional packages to install" you'd use "ubuntu-mate-desktop"
[05:27] <EldonMcGuinness> well lets see if this preseed thing works
[05:29] <EldonMcGuinness> Hey White_Light did not see your post until now, I happened across the preseed and replaced the one on the image with one I configured and am going to try it now
[05:29]  * EldonMcGuinness crosses fingers
[06:10] <EldonMcGuinness> meh kept getting dropped to a busybox cli, something must be amiss, o well
[11:33] <marlinc> Is there a package of Ubuntu MATE I can install on top of a existing Ubuntu Desktop 16.04 installation (with the default Unity environment) that wont impact Unity?
[11:33] <marlinc> So I can switch using the LightDM switcher
[11:39] <hoopotus> I don't think so. You can find instructions on how to remove Unity, I've done it once a few years ago but you will surely run into a lot of problems
[11:43] <marlinc> You know what, I'll just try, can just use a ZFS snapshot to rollback
[12:47] <Astro7467> @marlinc: believe just installing ubuntu-mate-desktop is enough as it's a meta package
[12:48] <Astro7467> definitely do a snapshot tho as MATE package will make changes to grub themes and beyond
[14:29] <Jack_Sparrow> !info abs-guide
[16:01] <EldonMcGuinness> I moved from ubuntu-gnome to kubuntu by basically comparing the two package lists and removing the difference and then installing the missing parts. Mind you this was all done via cli so there is that part
[16:03] <Jack_Sparrow> I mount just my Desktop on a spare partition so I can slide a fresh OS right under it, and a script to install the dowen apps I add in
[16:15] <voneus> how to use dual screen on ubuntu mate
[16:34] <hoopotus> do you guys know if it's bad, when I uninstall a package, because of the dependencies ubuntu-mate-desktop is also going to be uninstalled?
[16:34] <hoopotus> and ubuntu-mate-core is going to be uninstalled too
[16:35] <hoopotus> since I can't get that stupid avahi notification go away by using any of the instructions out there, I'd like to uninstall the whole avahi-daemon
[16:35] <hoopotus> but that would uninstall all of these:
[16:35] <hoopotus>   avahi-daemon avahi-discover avahi-dnsconfd avahi-utils libnss-mdns ubuntu-mate-core
[16:36] <hoopotus> does that mean that the compilation of packages that someone has desiced comes with ubuntu mate, wouldn't complete anymore and that's why ubuntu-mate-core gets uninstalled, or does it actually have an effect on something?
[16:42] <Jack_Sparrow> hoopotus, install inxi  and run this command Please Read, https://git.io/v1qUo  & share the link output here. Or
[16:42] <Jack_Sparrow> inxi -Fxxrzc0 | pastebin    in a terminal & share the link output here ..  If you dont have pastebin do it manually
[16:49] <hoopotus> Jack_Sparrow: ok here you go  http://taviuntelo.kirah.fi/~hoopotus/inxi
[16:51] <Jack_Sparrow> ok.. back
[16:51] <Jack_Sparrow> Updated kernel and only two ppas
[16:52] <Jack_Sparrow> so your trying to fix what by removing avahi
[16:52] <hoopotus> to disable that notification that comes everytime the wifi gets connected
[16:52] <Jack_Sparrow> Im guessing those are part of a meta package and removing them will resut in unexpected problems
[16:52] <hoopotus> there are plenty of instructions how to do it by googling for example disable avahi notification but nothing has worked yet
[16:53] <hoopotus> yes I thought so too. uninstalling ubuntu-mate-core doesn't sound good
[16:53] <Jack_Sparrow> the little popup top right ?
[16:53] <Jack_Sparrow> gpes away in 3 seconds
[16:53] <hoopotus> the one that talks about avahi yes
[16:54] <Jack_Sparrow> Im dont get that but gimme a sec..  save that info on your system for your own use later
[16:54] <hoopotus> mine doesn't go away until I click it. it seems like many other people get bothered by it too and that notification serves no purpose
[16:54] <Jack_Sparrow> Here I must confess, I use the mint version of mate..
[16:55] <Jack_Sparrow> I was going to see if I could figure out how to turn those off
[16:57] <hoopotus> ok
[16:57] <Jack_Sparrow> gsettings set org.gnome.nm-applet disable-disconnected-notifications "true"
[16:57] <Jack_Sparrow> gsettings set org.gnome.nm-applet disable-connected-notifications "true"
[16:57] <Jack_Sparrow> Or open dconf-editor and scroll down to org ▸ gnome ▸ nm-applet and check disable-connected-notifications and disable-disconnected-notifications settings there.
[16:57] <Jack_Sparrow> Is where I am looking now
[16:57] <hoopotus> that notification looks like this  http://2.bp.blogspot.com/_DPdQE6b-uQw/SsJG6W5QRYI/AAAAAAAAADM/mvDVjFva_LQ/s320/NetworkServiceDiscoveryDisabled.png
[16:57] <hoopotus> but I'll keep trying
[16:58] <hoopotus> that notification is not actually the normal wifi connected notification but some totally useless one
[16:58] <Jack_Sparrow> ok thats an important note
[16:58] <Jack_Sparrow> hold, dont just supress it
[16:58] <Jack_Sparrow> need to fix tha cause
[16:58] <hoopotus> are you serious
[16:59] <hoopotus> "Avahi is a system which enables programs to publish and discover services and hosts running on a local network. For example, a user can plug their computer into a network and have Avahi automatically advertise the network services running on the machine which could enable access to files and printers."
[17:00] <hoopotus> as far as I've read, it's used for example to share printers. might be good if you want to do that but if not, then that notification everytime is just annoying
[17:03] <Jack_Sparrow> hoopotus, get into your wireless setup
[17:03] <Jack_Sparrow> set ipv6 to ignore
[17:03] <Jack_Sparrow> in ipv4 set dns as 8.8.8.8   and secondary   8.8.4.4
[17:04] <Jack_Sparrow> restart and come back
[17:06] <Jack_Sparrow> hoopotus, is the router and connection yours? or shared
[17:11] <hoopotus> thanks for advice, I'll try those things a little later. I usually don't use any public network
[17:12] <Jack_Sparrow> hope something there will help
