Forwarding this bug from Ubuntu reporter rww: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/757141 [Problem] Intermittent failure (GPU lockup) booting live usb environment with Unity/Compiz. Out of 10 boot attempts, it experienced this gpu lockup 3 times. 4/10 times it booted properly. 2/10 times the monitor powered off. 1/10 times the kernel showed an oops message. [Original Description] I booted a LiveUSB of the current natty daily ISO. It got to the screen where it asks whether I want to Try or Install Ubuntu. I selected "Try". It switched back to the console, then loaded xorg with a cursor in the center of the screen and a black background and stopped. I could move the cursor around with my mouse, but Ctrl-Alt-F1 didn't do anything. I eventually did Alt-Sysrq-R and Alt-Sysrq-K to restart xorg, logged in on gdm, and got to a normal desktop. 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV620 LE [Radeon HD 3450] [1002:95c5] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
