in /var/log/xorg.0.log file, shows error message. googled error message, no efficient solution found.

(ee) ast: pci device 0x2000 @ 06@00:00:0 has kernel module claiming it.

(ee) ast: driver cannot operate until has been unloaded.

i think following relevant one: (ee) failed initialize glx extension (compatible nvidia x driver not found) pixels@pixels-sys-7048gr:~$ cat /var/log/xorg.0.log
