Red Hat Bugzilla – Bug 508371
X session froze; only mouse pointer moves
Last modified: 2010-04-14 03:40:41 EDT
Description of problem:
I'm running KDE on F11 updated to the latest updates in updates/.
While writing out a mail in gmail on firefox, my X session just froze with only the mouse pointer being able to move around the screen but no input being accepted. No keypresses from the keyboard were going through.
I had KDE's windows desktops enabled.
Curiously, X hogged about 1-3% of my CPU all the time when I had seen 'top' output earlier. After this freeze, I could log into the machine via ssh and 'top' output didn't show using any cpu cycles at all.
There's nothing interesting in Xorg.0.log or dmesg. I also ran a 'grabtest' test (over ssh) from the grabtest.c file I got off some BZ. It could grab both the keyboard and the mouse successfully.
I'll attach my Xorg.0.log, dmesg output and 'ps fax' output.
One interesting thing to note: My laptop went into suspend-to-disk this evening after the battery ran out. I had faced similar issues of keyboard/mouse lockups in F10 as well and they also could have be because of suspend-to-disk. I routinely suspend-to-ram and resume and that hasn't landed me into any trouble. So after wakeup from S-T-D, there could be some inconsistent state that might cause this.
