ATI reboot and/or freeze

[Raph]

This is a serious bug, I am not sure if is fglrx, xorg or kde, but the problem appear on 10.04 and 10.10 that I had tested before downgrade kubuntu version, for looked if the bug persist.
If I enable the 3d effect my computer reboot about 3-4/day without any warning. And if I disable the 3d effect this decrease about 1-2/day reboot.
In 10.10 devel version it was more freeze than reboot but I have looked in the log the fglrx write lots of error log, unfortunately I have not the log to show. And this appear with all version of kernel.
