Title:
Xorg freeze when pressing ctrl-alt-down arrow
Status in “nvidia-graphics-drivers” package in Ubuntu:
Confirmed

When pressing ctrl-alt-down arrow windows are listed, but only painted
halfway and the system locks. Moving between desktop with ctrl-alt
left/right arrows works fine. I recovered by using sysrq-k.
