I see something similar on my work machine with ATI (unsure of the
actual card specs). I've worked around this by switching to the TTY which I did startx from and sending it a ^C. This has worked for me flawlessly so far.
Hi, thank you for your suggestion but in my case, when the problem occours, keyboard and mouse are unresponsive
Right. Same here. I should have mentioned that the ^C sent to startx is the "logout" action here :) .
Sorry Ben, now it's clear, thank you :-) and I will do some tests and I'll let you know the result. However i think that by this way you have never correctly closed X environment. Do you suffer any collateral effects ?
