This *may* be related, though I'm not 100% sure. Today, I was running updates in synaptic and writing an email in Thunderbird at the same time.
I selected some text and tried to drag it to a new position in the email. X completely locked up. I could move the mouse pointer but couldn't click on anything. Ctrl-alt-backspace (I have it set to kill the X server) did nothing. Alt-sysrq-REISUB brought about a reboot, but a grub error ensued. /dev/sdb (sata disk 2) had completely disappeared from the BIOS listing!! Disconnecting power entirely for a few minutes solved that problem. Had something of this kind not happened to me previously, I'd have been in a first-class panic. Once the system was reloaded, the mouse pointer was still locked and another reboot was needed to fix that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/967905 Title: Xorg using excessive CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/967905/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
