I also found something interesting : I can boot LIVE lastest ubuntu (32 or 64) using these steps :
- Boot on ubuntu CD (by pressing C key)
- Press F6, then ESC
- replace "quiet splash" by "nomodeset xforcevesa acpi=off"
Live is wroking. I tried to replace in /etc/X11/xorg.conf device "vesa" by "radeon", then log off / log on .... black screen.
let see what you suggest me. "Or boot from ubuntu 11.04 live cd... is that what you tried ? it worked well for me.". Yes, it's what I tried. still black screen. Jeremy told me patches are available here : https://bugs.freedesktop.org/show_bug.cgi?id=26891
Kapouer :
