[Solved] LXQT desktop crashes.

ranurag · 2023-09-16 20:13:11

Message
When I open the lxqt-session with statx (via .xinitrc). Every thing is working fine but the warning " The desktop crashes too many times and the auto start fails.". From my observation to this is, it generates warning for the desktop features that it will not work. Because configuring desktop is not effective no changes relies. The output is blank screen. While the other features are working fine like panel, power management and other services.

Yup, and sounds very much like https://wiki.archlinux.org/title/PCManF … g_X-server

New error:

Segmentation fault (core dumped)

I tested it on new arch machine.
Got the same massage "Desktop crashes and autostart failed".
But this time error is different.. But instead of nouveau i have installed the nvidia driver.

You're more likely also running on the inte chip.
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General and the outputs of "glxinfo -B" and "printenv"

Are you *deliberately* running https://wiki.archlinux.org/title/Multih … te_screens ?
Are you trying to run lxqt on :0.0 or :0.1 ?

Please replace the oversized image w/ a link. It also doesn't tell much.

The server for which you posted a log btw. also failed to start:

Sorry, For the Xorg log here is the updated one.
http://0x0.st/HO1x.0.log

 
[    15.648] (EE) AIGLX error: dlopen of /usr/lib/dri/i965_dri.so failed (/usr/lib/dri/i965_dri.so: cannot open shared object file: No such file or directory)
[    15.648] (EE) AIGLX error: unable to load driver i965

I change the config (just to see), intel driver (i965) for screen :0.0.
same result.

You changed what config to what?

Remove xf86-video-intel.

Also you've still not answered whether you're deliberately using this kind of setup - there're no outputs attached to the nvidia chip, what makes all of this rather strange.

ranurag · 2023-09-18 08:43:09

I am using the default config generated by xorg/nvidia. (form arch wiki - ( Xorg :0 -configure/nvidia-xconfig)).

> xorg.conf
http://0x0.st/HOjz.conf

> xorg.conf.d/gpu.conf
http://0x0.st/HOji.conf

xorg log
http://0x0.st/HOjH.0.log

After removing xf86-video-intel the xorg session stucks and I have to kill it from tty2. Reinstalling it works fine, but the problem lies the same.

seth · 2023-09-18 09:09:37

The server fails because you still reference the intel driver.
Remove the config you generated, it's completely wrong for yor setup.
Also remove xf86-video-intel
Then post an updated xorg log.

https://wiki.archlinux.org/title/Xorg#Configuration wrote:

Note: Arch supplies default configuration files in /usr/share/X11/xorg.conf.d/, and no extra configuration is necessary for most setups.

your xorg conf has 8 lines that do something meaningful and that something is forcing X to use xf86-video-intel and the nvidiia proprietary driver.

The gpu.conf file has the same 8 lines .
remove both files.

Thank you for your time. Always appreciable.
So the problem starts with lxqt and end with xorg config. . It takes my lots of time to configure/debug the lxqt but I should take these expert advises from here first. Thank you and also welcome for my next issue soon .

ranurag · 2023-09-18 11:07:29

But the point arises, after removing the xorg.conf file and files form xorg.conf.d, the session works when restarts. But it not generates new xorg conf file so, don't xorg need these files?

seth · 2023-09-18 15:26:30

The Xorg server has decent autodetection abilities and generally does the right thing™ (ie. what Joe User wants/expects) for any given hardware.
Nudging and overriding the config is done via drop-ins that are usually provided by the related packages.

The only reasons to write a local server config are usually if you've very exotic hardware or very exotic ideas on how the server should be configured and think "jaja, I know this is for most people but I want something different and I know better than the Xorg server" and then you know better or show up here to ask why your config doesn't work

You *never* want to have a static server config "just because".
