Bug Description
Binary package hint: xorg
Hello!
I recently updated to Lucid. I noticed this problem:
When I suspend the computer, everything seems OK. However, when I resume, the screen remains turned off. I can see the system turned on—for example, the numlock key turns the LED on and off—but the screen doesn't turn on.
The only thing that seems to work is pressing Alt-F6 and then Alt-F7. I tried pressing other keys (in case the problem was just the screensaver) but that doesn't work. Neither Alt-F7 directly nor other Alt-F# followed by Alt-F7 works.
Once the screen turns on (after Alt-F6 and Alt-F7), the password dialog of the screensaver* comes up and I can continue my session. (* I have my computer set up to lock the screen, but with no actual screensaver on other than turning off the screen.)
Note that after the session resumes I experience bug #528138 which might be related somehow.

I have a similar problem on a Dell Vostro 1500 (nVidia Corporation G86 [GeForce 8400M GS]), running Lucid Alpha 3 (2.6.32-15-generic) with nvidia-current (195.36.03).
Suspend works, but on resume the screen is blank. Switching to tty (Ctrl+Alt+F2) followed by Alt+F7 / Alt+F8 sometimes brings back the GDM login screen, but not always. When that doesn't work, it requires a hard reset.
