[SOLVED] Cannot launch gnome using startx after trying multi montors

Hello All,

My system with single monitor was previously working well but I want to have a try with dual monitors with one nvidia-card.

After some modification, my dual monitor does not conf right and what's wrose: my single monitor gnome cannot launch any more.

Now I want to get back to my previous working single montor first. Please help me.

I have a nvidia card

18:00.0 VGA compatible controller: NVIDIA Corporation G86 [Quadro NVS 290] (rev a1)

I launched nvidia-xconfig to generate a xorg.conf

exec gnome-session

I have uncomment twm and xclock xterm lines and comment gnome-session, serveral windows can be launched.

Now the twm and xclock xterm has been commented and I left gnome-session there.

I checked /var/log/Xorg.0.log content as well. But I did not find much useful information.

Re: [SOLVED] Cannot launch gnome using startx after trying multi montors

The problem is gnome-session, the X11 server is running fine. => Check your journal on why gnome-session (likely gnome-shell) fails.

Re: [SOLVED] Cannot launch gnome using startx after trying multi montors

Hi Seth,

Thanks a lot for your guide.

I am re-launching the startx and get the last few lines from journalctl output.  I am not sure if I am doing it in the expected way ?

Also I previous has a xscreensaver installed and config in .xinitrc file as well. To make the problem isolate, I am delete the conf lines from .xinitrc and erase it (xscreensaver-arch-logo) completely from my system. I am not sure if this is relevant info or not ?

I saw there are some related logs with gnome-session, but I am still not sure how should I continue investigate this ?

Remove the nvidia-generated xorg.conf and downgrade libepoxy.

Re: [SOLVED] Cannot launch gnome using startx after trying multi montors

Hello Seth,

After I delete generated conf and downgrade the libepoxy from 1.5.0 to 1.4.3. My gnome can be launched successfully. And my dual monitors is working well automatically. Thanks a lot for this workaround.

I am going to marked my topic as solved.

By the way, I read <<KWin stopped working properly>> https://bbs.archlinux.org/viewtopic.php?id=235021 . I am not able to figure out how I could get the connection between my "software acceleration failure" and JonnyRobbie KWin problem.

If I want to learn more about this issue, would you please give me some links/guides I could do further study on this ? Thanks a lot.



Best regards,
wushuzh

Re: [SOLVED] Cannot launch gnome using startx after trying multi montors

I am not able to figure out how I could get the connection between my "software acceleration failure" and JonnyRobbie KWin problem.

- You're both on the same, very specific, driver (nvidia 340)
- You both have a failing compositor
- Both compositors use epoxy
- Both compositors have a wrong idea about the used driver

This is nothing I studied or would know how to study. There was a strong pattern and my synapses probably fired like wild ;-)
The issue is probably just a stupid bug in libepoxy (an abstraction for various GL versions) - you could git bisect https://github.com/anholt/libepoxy/commits/master
