Title:
Screen switches off some seconds after wake up from suspend
Status in “xorg” package in Ubuntu:
New
Bug description:
I was running Xubuntu 12.04 on a Thinkpad X40 which has an Intel 855GM
graphics chip. On 12.04 suspend worked flawlessly. Yesterday I
upgraded to 14.04 and this broke suspend. The problem is like this: I
close the lid, the laptop goes to sleep. After some time I open the
lid, the screen goes on and if I'm fast I can even start typing in the
password. However, some seconds later the screen switches off again,
though I can hear that the system continues working. I can still
switch to any TTY, only X has no graphical output. If I kill X from
TTY, it starts again, I can login and then the system works as
expected. In /var/log/Xorg.0.log I see following lines:
(II) AIGLX: Suspending AIGLX clients for VT switch
(II) AIGLX: Resuming AIGLX clients after VT switch
(II) AIGLX: Suspending AIGLX clients for VT switch
which exactly fits to my observations: On lid close the screen goes
off, on opening the lid it goes on and then after some seconds off
again.
