| |

| 14:12 | <callan> hi guys. i was testing video stuff on my thin clients, and many programs respond with "libGL error: failed to load driver: i965". when I check running drivers with lspci, I get ast and radeon (which are the ones on my server)
| |
| 14:12 | any way to get the i965 driver to load client-side?

| 17:59 | <alkisg> vagrantc: I managed to get Unity in 14.04 running in both thin and fat clients :)
| |
| 18:00 | I'll put the necessary changes in X50-generate-env so that we won't need 2 files like 40-ltsp-client and 40-ltsp-server
| |
| 18:00 | I've only have one thing left... upstart in 14.04 requires /sbin in the PATH :(
| |
| 18:01 | It's strange that it does work :-/ Anyway I've pinpointed the "why it does work with lightdm but not with ldm" part down to su's pam
| |
| 18:01 | ssh, sudo etc pam read /etc/environment, su - doesn't
| |
| 18:02 | And I want to change the way we run the fat client session from `su -` to plain `su`, is that ok?
| |

| 18:27 | <alkisg> Proposed diff: http://paste.debian.net/181731/
| |
| 18:29 | Err, without this line, CLIENT_ENV="$CLIENT_ENV PATH=\"/sbin:\$PATH\""
| |
| 18:36 | Hmm, while it works fine without the "-", it does preserve some of the ltsp environment variables, like PWD, $SERVER etc
| |
| 18:37 | sudo would be OK but it's not installed in debian
| |
| 18:37 | Manually adding /sbin to the PATH would also be an option,
| |
| 18:37 | and finally sourcing /etc/environment would work too
| |
| 18:37 | championofcyrodi has left IRC (championofcyrodi!~cott@50-205-35-98-static.hfc.comcastbusiness.net, Quit: Leaving.) | |
| 18:41 | <alkisg> Ah and another one would be to manipulate the su defaults from init-ltsp.d
| |

| 18:49 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 18:51 | <vagrantc> alkisg: if you put it all in the same file then the packages will conflict with one another
| |
| 18:51 | <alkisg> vagrantc: no, I'm putting it to ldm
| |
| 18:51 | <vagrantc> alkisg: ldm and ldm-server?
| |
| 18:51 | <alkisg> No, only ldm
| |
| 18:52 | See the proposed .diff above ^
| |
| 18:53 | The final line is something like this, in init-ltsp.d:
| |
| 18:53 | sed 's,^ENV_PATH.*,ENV_PATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games,' -i /etc/login.defs
| |
| 18:53 | This, at least in Ubuntu, forces su - to give the same path as login, sudo, lightdm etc
| |
| 18:54 | Ah I'll use the value from /etc/environment for the sed
| |
| 18:56 | That sed line may go either in ldm or in ltsp-client... I think we should put it in ltsp-client as we'll need it in the future with other DMs too
| |
| 18:56 | I can keep the sed in the ubuntu init-ltsp.d subdir if you prefer
| |
| 18:57 | <vagrantc> alkisg: does this run after the .dmrc saving of the session?
| |
| 18:57 | <alkisg> su - runs at X95-run-x-session
| |
| 18:58 | The sed part can be ran whenever before that, but it only needs to run once
| |
| 18:58 | <vagrantc> no, i mean setting DESKTOP_SESSION
| |
| 18:58 | <alkisg> Right after dmrc
| |
| 18:58 | It's the next script
| |
| 18:58 | <vagrantc> this is all to workaround ubuntu bugs?
| |
| 18:59 | <alkisg> Not exactly... the trend is for DMs to provide DESKTOP_SESSION
| |
| 18:59 | <vagrantc> or is some of this necessary regardless?
| |
| 18:59 | <alkisg> I haven't seen any DE break if you don't define it though, except for ubuntu with upstart :)
| |
| 18:59 | If you are in debian now, can you check if you have $DESKTOP_SESSION and the other 2 vars?
| |
| 18:59 | I'll boot up a fedora vm to check there too
| |
| 19:01 | <vagrantc> yeah, i've got DESKTOP_SESSION=gnome with gnome3 (from gdm3)
| |
| 19:01 | <alkisg> And XDG_CURRENT_DESKTOP and SESSIONTYPE ?
| |
| 19:02 | <vagrantc> and the /sbin is so that upstart works?
| |
| 19:02 | <alkisg> Yes, I believe that's a bug
| |
| 19:02 | But we can keep the login.defs sed'ding ubuntu-specific
| |
| 19:02 | <vagrantc> no sessiontype
| |
| 19:03 | so, if i remember correctly, there were issues running "su" vs. "su -"
| |
| 19:03 | <alkisg> I'll keep it as `su -` and sed through login.defs to modify the PATH
| |
| 19:03 | <vagrantc> it leaves variables and such
| |
| 19:03 | <alkisg> I'll copy the path from /etc/environment to login.defs
| |
| 19:04 | In fedora I have DESKTOP_SESSION but no other vars
| |
| 19:06 | About XDG_CURRENT_DESKTOP: http://lists.freedesktop.org/archives/xdg/2011-July/012004.html
| |
| 19:07 | xfce and lxde seem to agree with canonical there
| |
| 19:07 | I don't think it will hurt to provide those 3 vars
| |
| 19:09 | <vagrantc> sure
| |
| 19:09 | <alkisg> Cool, I'll commit these 3 changes tomorrow :)
| |
| 19:09 | <vagrantc> though it is a little painful looking at the code needed to set them :(
| |
| 19:10 | <alkisg> That's because of ldminfod inefficiencies
| |
| 19:10 | First it started by sending only the exec line
| |
| 19:10 | Then someone added the desktop file name too
| |
| 19:10 | Now we also need the Name= line of the desktop file...
| |
| 19:11 | When we drop ldminfod and implement ltspd, it'll get a lot more simpler
| |
| 19:11 | No ssh needed, we'll be able to generate the xsession.desktop files for lightdm just by consulting ltspd
| |
| 19:11 | * vagrantc feels like all of the variable are workarounds for bad design | |
| 19:11 | <alkisg> Yeah :(
| |
| 19:12 | <vagrantc> layers upon layers of variables that all define nearly identical things
| |
| 19:13 | * vagrantc wonders how long lxde will last with new development shifted to lxqt | |
| 19:13 | <alkisg> pcmanfm seems to work on it full time
| |
| 19:14 | What I would like to see is kde decoupling its executables from its frameworks... i want to install kolourpaint and i have to get phonon too :(
| |
| 19:23 | Whoops, we need to read X-LightDM-DesktopName from the .desktop file too :-/
| |
| 19:23 | https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1212408
| |
| 19:26 | * alkisg hates that we have to maintain a DM in LTSP :-/ | |
| 19:27 | <alkisg> LightDM says X-LightDM-DesktopName, GDM says DesktopNames, and systemd says XDG_SESSION_DESKTOP
| |
| 19:27 | What a mess
