Public bug reported:
Hi,
I've installed 15.10 beta on a brand new ASRock beebox N3150 PC. This
device has three display connectors, 1x DisplayPort, 2xHDMI. I'm having
a Display with 2560x1600, and thus want to use with with DisplayPort for
full resolution.
When connecting screen and PC with DisplayPort, both the BIOS and the
Linux BootSplash/Console correctly recognize the screen to be connected
to DisplayPort and are displayed as usual. But as soon as X starts,
screen becomes black (and the screen itself somewhat confused, because
it does not even respond to the menu button anymore). Interestingly, the
same screen worked properly when connected with DisplayPort to another
Linux machine with 14.04.
Connecting the screen with HDMI instead works without any problems, but
gives a reduced resolution of 1920x1080 only.
regards
