** Description changed: Laptop ASUS X51R freezes when battery powered with Ubuntu 10.04 No problems when AC powered. Two scenarios to reproduce the problem: a) 1. Boot up Ubuntu with AC supply disconnected but battery powered. 2. Ubuntu will freeze somewhere during boot process before login screen is displayed. I think it happens around the time X is started. In most cases get fancy patterns displayed on screen, more rarely screen stays blank. b) 1. Boot up Ubuntu with AC supply connected. 2. Logon to the system. 3. Gnome Desktop is displayed. 4. Pull the plug of AC. 5. It takes about 1 or 2 seconds. Screen freezes. Laptop is more or less useless for me without the possibility of using it battery powered. I am a quite experienced C/C++/Java application programmer, but know few to nothing about system programming. However you could come back to me and guide me in which logs to look or what to do to trace down the problem. - Thanks + Thanks Thomas ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: linux-image-2.6.32-23-generic 2.6.32-23.37 Regression: No Reproducible: Yes ProcVersionSignature: Ubuntu 2.6.32-23.37-generic 2.6.32.15+drm33.5 Uname: Linux 2.6.32-23-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
