Public bug reported:
Binary package hint: xorg
I upgraded from Ubuntu Feisty to Gutsy. In Feisty I hadn't any problems
related to X. I easily ran the Laptop for 30 days with suspend/resume.
I am using a Thinkpad R40 with Radeon 7500.
>From time to time X freezes, i.e. no mouse cursor, nothing moves. Doing a
>SysReq + S works. In the kern.log I see after a reboot:
Mar 1 11:04:42 tp kernel: [95316.248000] sd 3:0:0:0: Attached scsi generic sg1

My Device Section from xorg.conf looks like:
Section "Device"
Identifier "card0"
Driver "radeon"
VendorName "ATI Technologies Inc"
Option "DynamicClocks" "on"
Option "monitor-VGA-0" "mon-vga"
Option "monitor-LVDS" "mon-lvds"
EndSection
