I have been running two monitors with no problems for a while and picked up a 3rd when it went on sale today. Ive been trying to make it work for the past 4 hours. Xinerama works… but with its limitations of course. I use conky and not being able to use double buffer it flickers really bad and I cant have that. I can make monitor 1 & 2 work as screen0 and monitor 3 work as screen1… but that sucks too =P Monitors 1 & 2 are on gpu0 and monitor 3 is on gpu1
I don’t know if I’m just not googling the right thing… but anything I have come up with has not worked. I am using Xububtu 14.04 (x64) with 2 EVGA GTX580 SC 1.5gb cards and 3 AOC I2757FH 1080p monitors all connected with DVI->HDMI cables. I have tried various drivers (331-340) manually installed and the ones in ubuntu’s repos and all spit out the same “error”. I can completely configure what “should” work using the nvidia-settings gui no problem… it just wont start.
the attachment below has the output of nvidia-bug-report.sh. I also added in my Xorg.0.log of it falling on its face and a xorg.conf (that nvidia-settings made).
