Reading this thread there seems to be 2 distinct bugs. I am getting the really bad one (frozen keyboard so no access to tty on the machine, only remote ssh and restart lightdm possible to get access again) on a HP 5750 AMD64 Athlon x2.
System hangup occurs when the screen locks after going idle for a while, or when switching between two logged on users. This didn't happen with 14.04 i386, so for this hardware it's specific to 16.04 (both with i386 and i686). I installed debug symbols for unity/compiz/lightdm. Attaching with gdb on unity or compiz doesn't yield any stack. Attaching to lightdm gives the same stack after and before system hangup (see attachment). Any help greatly appreciated! ** Attachment added: "gdb-lightdm.txt" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1301125/+attachment/4687971/+files/gdb-lightdm.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301125 Title: Lock screen after idle time freezes unity To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1301125/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
