I am running PCLOS 2012.02 (KDE version) on Dell Latitude E6420. According to lspci, my video card is
VGA compatible controller: NVIDIA Corporation GF119 [Quadro NVS 4200M] (rev a1)I have used PCC to configure the video card to use the proprietary driver, so that my /etc/X11/xorg.conf says
Section "Device"
Identifier "device1"
BoardName "NVIDIA GeForce 6100 to GeForce 360"
Driver "nvidia"
Option "DPMS"
Option "DynamicTwinView" "true"
Option "AddARGBGLXVisuals"
EndSection
and according to rpm -qa | grep nvidia, I have x11-driver-video-nvidia-current-295.53-1pclos2012 installed.
When I boot away from my docking station, I get the correct behavior (displaying on the laptop screen). When I boot while docked to my docking station with my TV plugged into the VGA port, I get the correct behavior (TwinView across my laptop monitor and the TV). However, if I first boot away from the docking station and then dock, I cannot get the TV to display anything. It's as though the TwinView feature requires a reboot (or at least a restart of X server).
Isn't there a way to define something like "display profiles" using the NVidia driver? I just want to make docking and undocking easier. What do others do in this situation?
