[Bug 706259] [NEW] [915GM] DVI output not working after laptop wakeup

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

I use an external TFT display (Dell U2410) connected to a Dell docking
station using the station's DVI output. My laptop is a Dell D410. I use
Ubuntu 10.04.1 LTS.

The DVI output works fine after a fresh boot but stops working when I
put my laptop into sleep mode (suspend to RAM) and wake it up again.
After the wakeup/resume the external TFT display reports "no signal".

I am not able to turn the TFT on again after that. Neither "xrandr
--output DVI1 --off" followed by a "xrandr --output DVI1 --mode
1920x1200" nor switching to another VT (Ctrl-Alt-F1 and -F7 again) will
bring the DVI output back to life. However, the machine is up and
running: I can use the laptop's internal display and reboot the machine
to get my DVI back.

I once tried a "vbetool post" on a textmode VT when the DVI output was
gone: it turned on the DVI output and gave me a black screen with
blinking cursor in the upper left corner but the X server was screwed
and eventually I had to reboot.

Please find attached the output of lspci, dmseg and the Xorg logfile
*after* I resumed my laptop (e.g. the state were DVI is not working). At
this very moment xrandr gives:

$ xrandr --verbose
