Currently Installed Video Driver
In Linux, there is two parts for the video driver, the kernel part and the X server part.
- Let's identify your hardware first. By typing lspci | grep VGA in a terminal, you should see a line with you graphic card description (even if not configured at all).
- Let's check the correct kernel driver is loaded find /dev -group video.
- Let's check the correct X driver is loaded glxinfo | grep -i vendor.
If you want more help, I would like the result of following commands: (Remember, never trust command line that people ask you to execute without knowing what it does.)
lspci | grep VGA lsmod | grep "kms\|drm" find /dev -group video cat /proc/cmdline find /etc/modprobe.d/ cat /etc/modprobe.d/*kms* ls /etc/X11/xorg.conf glxinfo | grep -i "vendor\|rendering" grep LoadModule /var/log/Xorg.0.log
