I confirm the post above. I did not have any problems on 10.04. Alt+PrtScrn+REISUB won't work in this case. If I remove ATI proprietary drivers and use open source ones, laptop will not freeze, but crashes X and throws me to login instead... I can also confirm that the fan starts to spin faster when the system freezes / logs me out. If I login with the safe mode session or low-res failsafe Xorg, system works fine...
I tried to move to older / newer kernel than the default one, but with no luck. Going back to pm-utils v.1.3 didn't solve the problem...no difference if it's on battery or AC power, it freezes anyway... Strange thing is that, if I reboot / shut down the system a few times, it starts to behave normally till the next reboot... ============ Dell Studio 1558 Intel(R) Core(TM) i3 CPU BIOS version: A11 02:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 4500 Series] Ubuntu Maverick 10.10 Linux 2.6.36-1-candela x86 32bit =============== -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/662998 Title: System freezes when running on battery -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
