I have a thinkpad T430 with nvidia NVS 5400 M graphics card.
I have two HP monitors, where one is connected via the VGA port and
another via the DVI port in the docking station.
However, the opensource drivers recognize only the VGA port. The
monitor on the DVI port is not even recognized.
I want to use only the two desktop monitors side by side as a single
big monitor and do not want the laptop monitor to be used when the
laptop is in the docking station.
I could get this setup working in Windows without any effort. But in
openSUSE 13.1 with the default opensource driver it failed.
With the proprietary nvidia driver from the nvidia repository in the
openSUSE repository, I could get both the monitors detected. But the
driver is very buggy. It freezes the entire display randomly and I
figured that it was doing so whenever it had to change the display
brightness for some reason. Also, another big problem is, it fails to
boot everytime and hangs the machine after the "setting up Plymouth
screen" (or some such message) in the bootscreen. If I boot via the
"Integerated graphics" setting in the bios to recover from this cpu
freeze on boot, I could realize that it was hanging during the
"setting up acpi display brightness" thing again.
I am not too sure if reporting a bug on the nvidia driver will make
any progress at all, considering that even Linus has not had much
progress with nvidia. Also I am not even sure where to report the bug
for the nvidia proprietary driver.
Now, is it possible to get the opensource driver to get the multiple
monitor support working somehow ? I do not mind installing
developmental patches or custom kernels if needed.
Any help ?
