what kind of desktop are you using and what version
what exact version of driver are you using
do you have a function key on it to switch between the normal screen view and projection mode?
A cheap workaround that is sometimes working: switch on the projector first with the laptop attached. Then boot up the laptop.
Check also if there is a manual channel switch for the projector. In this case it will be probably organized in a loop way:
one pressure channel one
second pressure channel two
third pressure video
this or similar. Such a routine might be detected by some proprietary protocol in Win7 but not in Linux. So then you will do have to press the button by hand.
I have found in the past that occastionally openSUSE does not detect the projector unless you reboot - sometimes the function key combination which some laptops have may also solve the problem. Having installed 11.4, these problems appear to have disappeared. So try rebooting/using function keys and if that doesn’t work try upgrading.
Hi, I’m not trying to hijack this thread, but I was wondering how to make these settings made using nvidia-settings permanent? I have to setup dual monitor settings each time I reboot, which is pretty inconvenient. (This is probably also relevant for the OP that’s why I felt free to ask here)
