Message #121658
[Bug 1460551] Re: Random screen locking
** Tags added: bios-outdated-a12
** Description changed:
Random screen locking happens about once an hour. Mouse is not
responding, keyboard is, but GUI does not respond. To overcome the
problem I have to switch to terminal with ctrl+alt+1 and go back. In
dmesg I can see:

Title:
Random screen locking
Status in linux package in Ubuntu:
Incomplete
Bug description:
Random screen locking happens about once an hour. Mouse is not
responding, keyboard is, but GUI does not respond. To overcome the
problem I have to switch to terminal with ctrl+alt+1 and go back. In
dmesg I can see:
