I've got an Asrock Extreme 3 motherboard and a Nvidia 660ti GPU.
I was trying to configure dual monitor on debian 7 connecting one monitor to the mb and the other to the GPU. This configuration works perfectly on Windows 7 without installing any drivers.
With debian only the GPU monitor is working. When I try to connect the second to the motherboard it shows the following:
Decompressing Linux... Parsing ELF... done. [ 0.0000000] tsc: Fast TSC calibration failed Loading, please wait... [ 3.222458] sd 8:0:0:0: [sdc] No Caching mode page found [ 3.222518] sd 8:0:0:0: [sdc] Assuming drive cache: write through INIT: version 2.88 booting [info] Using makefile-style concurrent boot in runlevel S. [ ok ] Starting the hotplug events dispatcher: udevd. [ ok ] Synthesizing the initial hotplug events...done. [....] Waiting for /dev to be fully populated...
After a few minutes it turns off.
This only occurs when I hotplug it. If I start the system with the monitor connected it doesn't turn on.
How can I configure it?
