Public bug reported:
Binary package hint: acpi-support
Hi! I have a Dell Latitude D620 laptop. It has some kind of Intel 9**
graphics and a widescreen monitor. I have set it to turn off the screen
when I close the lid instead of suspending, because I routinely leave
the laptop do stuff for long times.
This works well usually. The screen turns off when I close the lid, the
computer visibly works a bit afterwards (swapping; presumably it does
something to the X session) and when I open the lid it works a bit
again, wakes up in text-mode (you can see a cursor there, and the
resolution is clearly not native; this is annoying and should probably
be fixed, but it's not a problem), then turns to graphics mode and asks
for my password. (Sometimes the screen is blank until I move the mouse
or press a key; I think it's the screensaver that's the cause, I set it
to just blank the screen.)
Now the problem: if I close the lid and then I open it _quickly_, which
means approximately before the swapping stops, the screen remains turned
off. As far as I can remember, closing the lid and opening it ten or so
seconds later fixes this, but it's really annoying. I also had (some
time ago) problems with the laptop freezing when woken-up, and it's easy
to confuse the two.
Please let me know any information you might need (and how to get it) to
diagnose this.
