[Bug 1448761] Re: gray screen shown when external monitor connected on resume from suspend
I obtained the trunk like this:
%?master ~/lab> bzr branch lp:lightdm-gtk-greeter/trunk lightdm-gtk-greeter
You have not informed bzr of your Launchpad ID, and you must do this to
write to Launchpad or access private data. See "bzr help launchpad-login".
Branched 326 revisions.
Then I tried to build it:
%?master ~/lab> cd lightdm-gtk-greeter
lightdm-gtk-greeter:326 ~/lab/lightdm-gtk-greeter> ./autogen.sh
You need to install gnome-common from the GNOME CVS
exit 1
Then I installed dependencies:
lightdm-gtk-greeter:326 ~/lab/lightdm-gtk-greeter> sudo apt-get build-dep lightdm-gtk-greeter

Need to get 17.1 MB of archives.
After this operation, 105 MB of additional disk space will be used.
Do you want to continue? [Y/n]
...
After all that, I tried building again:
lightdm-gtk-greeter:326 ~/lab/lightdm-gtk-greeter> ./autogen.sh
You need to install gnome-common from the GNOME CVS
exit 1
Now I give up. Is there an easier way to test trunk?

Title:
gray screen shown when external monitor connected on resume from
suspend
Status in lightdm-gtk-greeter package in Ubuntu:
Confirmed
Bug description:
After resuming from suspend, the Xubuntu login screen is completely
gray if an external monitor is connected (see step 5 in the procedure
below). This problem started occurring after I upgraded to Xubuntu
15.04; it never occurred under the previous Xubuntu 14.10 version.
1. Connect external monitor to laptop's HDMI port.
2. Choose external monitor as the sole display to use (do not use
laptop's internal display at all: no mirroring or extending).
3. Suspend the laptop (put it to sleep) by closing the lid.
4. Wake up the laptop by opening the lid.
5. The screen is now completely gray on both the external monitor and
the laptop's internal display. The mouse pointer is also visible and
it responds to movements from the laptop's internal touchpad.
6. Disconnect the external monitor by unplugging the HDMI cable.
7. The regular login screen now appears.
8. Reconnect the external monitor by plugging in the HDMI cable.
9. The screen is now completely gray again, just like in step 5.
Please fix this gray screen issue! Thanks for your consideration.
