How do I edit the xorg.conf file, when there isnt one in Kubuntu 11.10?
I want to alter the video driver, but how do i do this in 11.10? The reason is that i believe I am having issues after a recent upgrage in 11.10, and now my desktop effects no longer work when using the OpenGL compositing, even with the functionality checks disabled...
however, is there a way to alter this file and have they moved it to a new location?
Any ideas?
thanks
sudo updatedb
and thenlocate xorg.conf
./etc/X11/
directory, but only if your Graphics driver has created it, if its not, you need to create it manually like @queueoverflow said.
