| moshe | bug confirmed by another friend | 08:26 |
|---|---|---|
| alkisg | It's possible that lightdm requires one of the missing stanzas, while other DMs do not require it. | 14:31 |
| alkisg | You could check which line makes the difference (starting from mate.desktop, changing Exec=i3), or you could directly file a bug against lightdm | 14:31 |
| moshe | I've looked at that already | 14:35 |
| alkisg | And you found the line? | 14:36 |
| moshe | didn't find anything obviously missing eyeballing i3.desktop against mate.desktop and jw.desktop | 14:36 |
| alkisg | Does it work if you start with mate.desktop and change just the Exec line to i3? | 14:37 |
| moshe | also, it's exactly the same file I had in 20.04 and lightdm has only received 2 minor updates since then | 14:37 |
| alkisg | I just tried apt install i3 in jammy-mate and it worked fine for me | 14:38 |
| alkisg | I selected it from the login screen and I'm now seeing the first configuration dialog | 14:38 |
| moshe | was the background of t he lightdm entries garbled ? | 14:40 |
| alkisg | no | 14:41 |
| moshe | not even sure if that's related tbh, I haven't messed about with that yet | 14:42 |
| moshe | https://paste.debian.net/plainh/c6aa72d6 | 14:42 |
| moshe | is your i3.desktop file the same ? | 14:42 |
| moshe | this is what 22.04 dropped in/usr/shar/xsessions after nuking and reinstalling i3 | 14:43 |
| moshe | oh wait I might have done a forced reinstall | 14:43 |
| moshe | but I do remember my friend's file being the same | 14:43 |
| moshe | purged, removed the files myself, reinstalled i3, nothing was put back into /usr/share/xsessions now lightdm can only find mate | 14:48 |
| alkisg | i3 installs i3-wm which has the session file | 15:01 |
| alkisg | If i3-wm is missing for you, something is wrong | 15:01 |
| moshe | the packages are installed | 15:02 |
| alkisg | My i3.desktop is termbin.com/2wyi | 15:02 |
| moshe | it's i3.desktop that didn't get put back in | 15:02 |
| alkisg | Use `sudo dpkg -V` to discover if you manually deleted files that you shouldn't have | 15:02 |
| alkisg | For example if you rm /usr/share/xsessions/i3.desktop, and then you apt install --reinstall i3, you're causing issues | 15:03 |
| alkisg | As that file is shipped by i3-wm, not by i3, so reinstalling i3 won't put it back | 15:03 |
| moshe | not what I did | 15:03 |
| moshe | uninstalled, purged, nuked the files, reinstalled | 15:03 |
| alkisg | What's the output of sudo dpkg -V | 15:04 |
| moshe | still running but so far nothing except ??5?????? c /etc/gnome/defaults.list | 15:04 |
| alkisg | Let it run. And you're saying you have no files in /usr/share/xsessions now? | 15:07 |
| moshe | a handful of files, most I don't recognize, and it's complaining about those 2 .desktop files | 15:07 |
| moshe | yes | 15:07 |
| moshe | reinstalling i3 didn't put them back in | 15:07 |
| alkisg | Run this: dpkg -S /usr/share/xsessions | 15:07 |
| alkisg | i3-wm, mate-session-manager | 15:08 |
| alkisg | These are the packages that you need to reinstall to get the desktop files back | 15:08 |
| alkisg | Not i3, not mate | 15:08 |
| alkisg | sudo apt install --reinstall i3-wm | 15:08 |
| alkisg | Also put the output of dpkg -V to pastebin | 15:08 |
| alkisg | Since the files that you don't recongnize might be importatnt | 15:08 |
| alkisg | s/importatnt/important/ | 15:09 |
| moshe | well I killed it to run the other command | 15:10 |
| moshe | and I fail to see how uninstalling i3 an following that up with an autoremove, to then install i3 and i3status, wouldn't put the files back in | 15:11 |
| moshe | and yet forcing a reinstall of i3-wm did put them back in | 15:11 |
| moshe | same content as what I pasted earlier | 15:12 |
| alkisg | It's what I'm trying to explain about package management | 15:12 |
| alkisg | When you uninstall or reinstall a metapackage, it doesn't automatically reinstall all its dependencies | 15:12 |
| moshe | autoremove | 15:13 |
| alkisg | So for example if you ever apt purge --auto-remove mate-desktop and then reinstall it, you completely break your installation | 15:13 |
| alkisg | As all the programs that depend on mate-desktop get removed by they don't automatically get back | 15:14 |
| alkisg | For me to help more, I'll need the output of `sudo dpkg -V` and `sudo dpkg -l` | 15:14 |
| moshe | anyway I'm going to log out and back in, see if that changed anything. If that did, then we still have a problem because the same thing happened on a clean install a few months ago, and inside a vm last night. | 15:14 |
| alkisg | In any case this isn't a development channel | 15:14 |
| alkisg | So you can't report bugs here, you can only get volunteer help | 15:15 |
| alkisg | So even if you are able to reproduce the issue in a clean installation (I wasn't, it worked fine for me), the next step is to report the bug | 15:15 |
| moshe | nope, fails and falls back to i3 | 15:15 |
| moshe | I have already | 15:15 |
| moshe | *falls back to mate | 15:16 |
| alkisg | > For me to help more, I'll need the output of sudo dpkg -V and sudo dpkg -l | 15:16 |
| moshe | I'm running them | 15:16 |
| alkisg | You may even test with a live cd if you wish | 15:16 |
| alkisg | apt install i3 in the live session | 15:16 |
| alkisg | Btw if you reported the bug, you may mention it here so that it helps with the discussion | 15:18 |
| moshe | I did it just as you started asking questions | 15:20 |
| moshe | I assumed it was why you were asking | 15:20 |
| moshe | https://bugs.launchpad.net/ubuntu-mate/+bug/1990771 | 15:21 |
| moshe | as for the output you asked for https://paste.debian.net/plainh/ab2de206 | 15:22 |
| alkisg | No dpkg -l output there | 16:06 |
| alkisg | You may run `dpkg -S filename` for the affected files | 16:06 |
| alkisg | It will show the affected package. By reinstalling it, you'll fix the dpkg -V issues | 16:07 |
| moshe | half of the dpkg -V output is on purpose | 16:07 |
| moshe | the other half I have absolutely no clue, I don't go around and nuke files willy-nilly so I can only assume they're leftovers from the previous install | 16:08 |
| alkisg | Installations and upgrades can't cause that dpkg -V output; in any case I've mentioned how to fix it | 16:10 |
| moshe | I'll look into it | 16:11 |
