Actually it seems to me that the bug is a bad interaction with light- locker/lightdm locking system (which relies on vt switch) and the Intel driver. It only seems to happens on this driver, and I think it's also been reproduced just by doing vt-switches (but can't remember where it was reported). > > Switching to another greeter from the default gtk-greeter appears to help > according to that bug, which may mean that the bug is actually in > lightdm-gtk-greeter.

There are at least a gazillion bugs against light-locker and lightdm, or xfce. I tried to at least merge some of them (like #846278) but clearly failed to identify all of them. And people are still reporting new ones (or posting to -devel) so clearly they are hard to spot. Maybe locking through vt-switch is a bad idea, I noted Andreas raised the severity, but I hope someone has an idea how to fix that because I don't.
