Bug Description
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.

Bogdan, please update the bug report with the output of
uname -a
Also, please run the following commands and attach their output to the report, one attachment per command:
sudo lspci -vv
sudo lspci -vvn
sudo dmidecode
Please be sure to attach as there will be a lot of output. Also please be sure to run with sudo, as these commands require root access to get to the required information.
It may also be useful to run
lshal -m
close the lid, get back to your session, then attach the output of the command.
Thanks!
