xfce crashing and going back to lightdm

dr_light · 2019-08-21 15:57:59

I'm using xfce with a motherboard that has integrated Intel graphics and a PCI-E Radeon card. I use the Intel output as the main display and the Radeon as a second, not mirrored. In XUbuntu 18.04 I used to put x.conf files in /usr/share/X11/xorg.conf.d to configure these cards for accelerated graphics and no screen tearing. Now, in XUbuntu 19.04, I can't get past lightdm with this setup. Everytime I try it crashes and ends up back at lightdm's screen. If I remove the x.conf files I can login, but there is screen tearing and I'm assuming there isn't acceleration. I need acceleration, however. Can anyone help me though this?

I even installed a nightly build of Ubuntu, then installed the xubuntu-desktop metapackage, and still the same problem.

Here is the .xsession-errors file output:

And this in journalctrl, though I have no idea if it's relevant:

Hello and welcome.

(EE) unw_get_proc_name failed: no unwind info found [-10]

If you search google for this string you'll find many bug reports - many seem to be geared towards the mesa package. This looks like an issue between the graphics card driver and the mesa package.

If I remove the x.conf files I can login,

Compare the Xorg.0.log files between the two different setups to see what differences there are between the drivers being loaded and used.

dr_light · 2019-08-21 18:22:40

Thank you for the help, ToZ. I will do some research on the bug reports.

I diffed the X logs and it appears on a successful start that it loads the ati module instead of the intel. I'm guessing that means it's mistaking the integrated intel graphics for ati? On a crash it is trying to load the intel and radeon.

Here is that section from the successful start:

Is yours a fresh install, or did your desktop work until recently?

I mean, exactly the same problem happened to me (Arch Linux 32bit) a week ago. – It appeared this had nothing to do with lightdm, which I disabled and tried to start X from tty, without success. And this was because only parts of the xfce4 package group got updated at that time. Meanwhile it’s complete, and so far all components of XFCE are working like a charm again.

Maybe this is the similar case to you, or some drivers or deps you use also need an update. So you could use a light spare WM for not being completely without X until your XFCE issue gets fixed by your distro.

It's on a fresh install. I haven't tried starting it from the command line yet, maybe that will show me something.

cy · 2019-08-26 19:10:42

I don’t know how you currently gain access to your Xubuntu.

However, be sure to login on a tty for now. For this you need to stop and disable lightdm (in a terminal):

systemctl --user stop lightdm
systemctl --user disable lightdm

When your problems are resolved you can start and enable lightdm again just the same way.

Then you need to create the file ~/.xinitrc; if you already got one, move that to another name or place first. In your (fresh) ~/.xinitrc, include the (final) line

startxfce4

with an editor. Save and exit the file, then execute

startx

and see what happens.

Thanks, cy. I'll try that.
