Bug#730609: gdm3: Laptop does not suspend when lid is closed

[Andreas Tille]

Package: gdm3
Version: 3.8.4-6
Severity: normal

Hi,

when using gdm3 3.6.4 after closing the Lid my laptop went into suspend
to RAM which is the expected behaviour also when working with any
desktop environment I know also after loging in.  Since I upgraded to
gdm3 in Jessie this does not happen any more.

The following works: Loging in via ssh and suspend manually.  In this
case I can go back to the loginscreen by pressing a random key.
However, it does not work if I use the suspend (in German locale
"Bereitschaft") from the menu at the switch in the upper right corner.
If I suspend with this method  after reopening the lid the login screen
is not accessible and only the clock (screensaver mode???) and some
arrow animation running from bottom into the direction of this clock.
The only available control is a Battery symbol in the upper right
corner.  When I click on it I can adjust speaker and microphone but
nothing else.

When gdm is not working usually it worked to `/etc/init.d/gdm3 restart`.
I also tried this but even a `/etc/init.d/gdm3 stop` did not killed the
X screen.  I manually `kill -9`-ed any process displayed at
`ps ax | grep gdm` which left me with a black screen and a frozen mouse
cursor.  I now tried

$ sudo /etc/init.d/gdm3 start
[ ok ] Starting GNOME Display Manager: gdm3.

... but there is actually no successfull start of gdm.  Sometimes it
happens that switching to text console and than choosing <Alt>-F8 brings
you to the correct screen but this is not used and <Alt>-F7 remains at
the black non-working screen.

I tried to downgrade to the previous version of gdm3 3.6.1-2 which endet
up in a dependency djungle which does not sound like a clever idea.

Kind regards and thanks for maintaining gdm

    Andreas.
