Thanks for your reply, Chris. I think you meant...
echo 6 | sudo tee /sys/module/drm/parameters/debug ...and I will attach the sequential xrandr outputs, X l.ogs and Dmesg for all three cases. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1218224 Title: VGA Output not activated Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: If I carry my suspended laptop into work and then connect it to the external Dell U2410f the monitor seems to be identified (visible in Grandr) but activating it doesn't cause any image to appear (it seems the signal is not sent). In order to succeed at seeing anything, I have to reboot the machine entirely, with the monitor attached, at which point it not only sees the monitor, but also sends it a signal.
