I have a experimental station that has a dual screen setup. The main monitor is a LED monitor and the presentation monitor, a CRT. This station runs on Ubuntu 14.04, KDE 4.14.3. I have tested presentation on both screens seperately, and they are able to display the psychopy window (visual.Window) screen properly when there is only one monitor connected to the PC at any one time. The problem arises when both monitors are connected to the PC. While I'm still able to get the window to appear on the LED (experimenter) monitor properly when
screen=1 resulted in the CRT (participant) monitor displaying only a black screen if
fullscr=True, and a black box-like window when
fullscr=False. The KDE background was still visible around the black box when
fullscr was on
False mode, suggesting that the window was setup, but the CRT couldn't properly display the stimuli content.
Matlab works fine on dual screen setup on this station. I have updated to the latest nvidia graphics driver as well. Has anyone got a suggestion to this?
