On Kernel 4.2.0-rc2 (compiled based on the stock kernel's config), the computer
just locks up:
I xscreensaver-command -lock, then logged back in (no issue there), then I
xscreensaver-command -lock again and the computer just locked up. Caps lock
light was unresponsive on the keyboard, Ctrl+Alt+Delete didn't work, RESIUB
magic keys either.
After hard rebooting the computer, here is what what in kern.log and syslog:
Jul 16 17:19:45 dioo-XPS rtkit-daemon[2678]: Supervising 4 threads of 1
processes of 1 users.
