Graphical interface suddenly not working after update

Graphical interface suddenly not working after update

Postby jimg » Jan 6th, '19, 23:13

I recently did an update and when I rebooted I got a message saying "Sorry, but there has bee a problem starting your graphical display." And putting me into a terminal to log in as root and fix things, and then enter "systemctl default".

I poked around a bit, uninstalled and re-installed task-x11, but no luck. I'm no afraid of using the command line but I'm not really sure how to diagnose the issue. Any ideas?

Naturally I'll be happy to post more information, just not sure what information is relevant.

If it's helpful the package x11-server-common-1.19.5-1.2.mga6 is installed. I thought perhaps there should be a corresponding x11-client-common package, but there is none.

Thanks,

Jim

Look in /var/log/Xorg.0.log to see if there are any helpful error messages

Xorg.0.log indicates that module v4l doesn't exist and couldn't be loaded. Also the module "intel" does not exist and also couldn't be loaded. Then it said that no drivers were available. Finally, it said
Code: Select all
(EE) no screens found(EE)

and this was a fatal error.

Could you please attach the whole /var/log/Xorg.0.log here? Also please post the output of
Code: Select all
lspcidrake -v

That's a little challenging because I have to get the files from one compute to another, using BASH. Could you tell me where a USB drive would show up and be accessible via BASH? And remind me how to mount it, if necessary?

Thanks!

Plug in the USB stick, then
Code: Select all
dmesg

That will show you which device the USB stick has been assigned to, e.g. /dev/sdb. Then, as root
Code: Select all
mount /dev/sdb1 /mnt
cp /var/log/Xorg.0.log /mnt
umount /mnt
eject /dev/sdb

replacing /dev/sdb1 with the correct device+partition. You can use any directory in place of /mnt if you already have something mounted there.

Thanks for everyone's input. I'm attaching Xorg.0.log as a file, and the results of lspcidrake -v as the file lspcidrake-out.txt.

The log says "(EE) Failed to load module "intel" (module does not exist, 0)". Is the x11-driver-video-intel package installed?

Thanks. The x11-driver-video-intel package is in fact installed.

Maybe some files are missing or have wrong permissions. On my system I have
Code: Select all
% \ls -l /usr/lib64/xorg/modules/drivers/intel_drv.so
lrwxrwxrwx 1 root root 30 Jan 16  2018 /usr/lib64/xorg/modules/drivers/intel_drv.so -> /etc/alternatives/x11-intel-so
% \ls -l /etc/alternatives/x11-intel-so
lrwxrwxrwx 1 root root 57 Jan 16  2018 /etc/alternatives/x11-intel-so -> /usr/lib64/xorg/modules/drivers/intel-common/intel_drv.so
% \ls -l /usr/lib64/xorg/modules/drivers/intel-common/intel_drv.so
-rwxr-xr-x 1 root root 1729976 Jan 10  2018 /usr/lib64/xorg/modules/drivers/intel-common/intel_drv.so
