I installed 11.1 on a Thinkpad W500 with XP dual boot, and found out that X windows doesn’t work everytime I come back from XP. Vice versa, the ATI driver stops working when I reboot from SUSE and go into XP. The only way to make it work is the take out the laptop battery each time when I switch between XP and SUSE.
Interesting bug, hope someone can fix it.
