Public bug reported:
Binary package hint: gnome-control-center
Having just upgraded to 9.10 successfully on my laptop, I plugged in an
external monitor, opened up the gnome-display-properties (belonging to
gnome-control-center 1:2.28.1-0ubuntu1) , and de-selected the "mirror
screens" checkbox. It offered by default that the external monitor
should have 1680x1050, with the laptop screen at 1024x768, but that it
needed to resize the virtual desktop before the settings would take
effect. I said okay.
On logging out, the laptop screen went to flickering without end, as in
a respawning X server, while the external stayed blank. I rebooted,
external monitor still connected, and the flickering display started
immediately after decrypting my drive, before X was even thinking of
starting. This new flickering prevented the startup process from going
forward, and persisted on my next reboot without the external monitor
connect. I restarted in recovery mode, and copied the old xorg.conf
into place to be able to file this report, but I haven't rebooted again
to see if the initial framebuffer death is still there. If so, I
imagine pulling the "splash" out of the boot options should be enough to
continue to use my computer.
