-- Information about the crash:
I put my display on laptop down, recover from sleep, work a few minutes, again suspend to RAM by closing laptop and quick recover, but there was no response, so I started to pressing some buttons (Esc, Enter, numbers, letters, mouse...) and get crash instead password window.

This is the first time it happens to me.
