Title:
internal display does not show up in nvidia-settings nor in xorg.conf,
making it unusable
Status in nvidia-prime package in Ubuntu:
New
Bug description:
I have a Dell Inspiron N7110, with nvidia graphics card.
My problem is, that when I try to use my external monitor in a dual display setup via HDMI, the internal screen is unusable.
I can mouse over to the internal screen. In KDE I can drag windows there, but otherwise it acts as if it was not part of the desktop. Under unity the whole desktop (both screens) just show some disorted desktop.
What I expected to happen:
Internal screen shows up in nvidia-settings and I'm able to arrange the displays.
What happens:
Only the HDMI screen shows up in nvidia-settings (HDMI is rigged to the NVIDIA card, internal display is rigged to intel).
I can see and arrange both displays in the display managers, which affects the displays' position, but does not solve the effect described above.
More problems:
I can modify xorg.conf to force it to crt recognition (remove the line Option "IgnoreDisplayDevices" "CRT" from xorg.conf).
This causes a phantom crt display to appear in the display manager and the nvidia-settings. If i manage to get this crt overlapping with the internal screen in the display manager, everything looks good. The problem is, everything gets lost when switching to intel, because xorg.conf gets removed.
