Bug#625806: kernel erroneously reports continuous changes in the connected displays

[Paolo Scarabelli <paolo@msw.it>]

Hi Jonathan,

Thanks for looking in to this, I now use testing (wheezy) with kernel
3.1.0-1-686-pae and everything works fine.

In general I had no problem with display geometry with the 3.x kernels,
I tried all the available ones in testing, sid and experimental since
3.x became available.

Only a couple of times, after updating some gnome packages the display
size is set to 1024x768 instead of 1366x768. Just that, no flickering
and no crash. I assume that it's a gnome issue since it happened only
after upgrading gnome related packages and a reboot solved the problem
in both cases.

This is unrelated, I've been trying all the available kernels because in
the new gnome 3 interface (gnome shell) I can see the battery icon
appearing and disappearing every 30 seconds or so, as if after charging,
the battery starts discharging again for a few seconds and then
recharging again. I haven't reported this yet because I still don't
understand which package causes this issue.

Regards,

Paolo.
