Package: nvidia-kernel-source
Version: 185.18.14-2
Severity: normal

after upgrading nvidia-kernel-source (and nvidia-glx) from 180.29-1 to
185-18-14-2 (and upgrading at the same time from kernel 2.6.26-2 to
2.6.30-1), i get the following behaviour:

My (dell) laptop is plugged in a docking station connected to lcd
monitor. I boot with the laptop screen closed, so the primary and only
display for X is the monitor. i then open the laptop screen, launch
nvidia-settings, activate the laptop screen (resolution set to auto)
and deactivate the monitor (resolution set to off). I then suspend to
ram, unplug the laptop, then resume the system. At this point all
works perfectly.

Then i suspend to ram again, plug back the laptop to the docking
station, resume the system, then with nvidia-settings, i reactivate
the monitor and deactivate the laptop screen. Again, this works well
but from then on i get some kinds of screen "flashes" or flickering
every 5 to 30 seconds or so. Sometimes they do not occur for a while.

if at this point i restart X without rebooting the laptop,
nvidia-settings is then unable to detect the external monitor.

GPU is a Quadro NVS 135M (laptop is dell D630)

suspend to ram method is hibernate, with the following configuration:

USuspendMethod ram
Include common.conf
EnableVbetool no
USuspendRamForce true
SwitchToTextMode false
DownInterfaces auto
UpInterfaces auto
FBSplash on
