X Hangs in UseFBDev
 

Hey everyone, I ran into a problem when using Xorg 7.1's radeon driver to start in framebuffer mode. My system is fedora 7 on ATI X600 mobile video card on a ThinkPad Z60m. Manual "modprobe radeonfb" succeeded, and then startx failed. The xorg.conf is:

Section "Device"
Identifier "Videocard0"
Driver "radeon"
Option "UseFBDev" "on"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

The keyboard is not locked when X hangs, and I can see a cursor is flashing in framebuffer console mode. but switch to any other virtual terminal does not work.

Any suggestions? Thanks a lot!
