But xserver-xorg-video-radeon would be the right driver to use. Now you're using the much simpler vesa driver. The Xorg.0.log file shows that X is searching for the ati driver (package xserver-xorg-video-ati) which will then use the radeon driver from the xserver-xorg-video-radeon package. Try the ati package and if it fails or not, let's look into the contents of the Xorg.0.log file of that again. >> Could you show us the contents of your Xorg.0.log (either >> ~/.local/share/xorg/Xorg.0.log or /var/log/Xorg.0.log)? > I'm attaching the file, as it has more than 1000 rows. >> >> How is the monitor connected to the computer (VGA, HDMI, Display Port, ..)? > Currently I am using an HDMI cable, but I also can use DVI, which > currently gives me glitchy screen.
