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 Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA1 unknown connection (normal left inverted right x axis y axis) Identifier:
