I have been using the radeon driver on two PC running older Cooking versions but it appears there are problems with Slitaz 4 running radeon.
I booted off Slitaz 4.0 livecd installed radeon driver (default vesa driver gives me a shimmering screen which is almost impossible to read!) and modified /etc/X11/xorg.conf.d/60-Devices.conf to replace vesa with radeon. When I exit X session, I get black screen. Ctrl+Alt+F2 (or Ctrl+Alt+BKSP as someone else mentioned in another post) does not take me to a command prompt either.
I would appreciate any help with this. Thanks
