1. I use ubuntu 16.04 / cuda 8.0 / gtx-1070 (nvidia-367.44 driver)
  2. I used two monitor and it worked well
  3. When I install nvidia-367.44 driver, one of my monitor doesn't work
  4. ubuntu 'setting'->'display' menu doesn't work.
  5. The two monitors are connected with main board (cpu intel graphic card. not gtx-1070)
  6. when I connect the one(not working) to gpu instead of cpu, the monitor detect it but it doesn't work well because of resolution problem

    7. How can I fix it? Actually, I want to connect two monitor to cpu not gtx. and I want to use dual monitor.

I already tried some methods
Cannot open "Display" settings, error "Could not get screen information"
Ubuntu 14.10(Utopic Unicorn), Displays menu is Broken?
Ubuntu "Could not get screen information" after upgrade
Graphics issues after/while installing Ubuntu 16.04/16.10 with NVIDIA graphics

How can I detect and use the another monitor well?
Thank you in advance!

  • Yeah same thing happened to me just 3-4 days ago, i spent days trying to figure it out but just couldn't. I finally completely wiped out ubuntu and reinstalled it that fixed the problem. I don't recommend installing any kind of Nvidia driver if you are using double graphic card(one integrated) dual monitor setup. – Mustafa Yılmaz Sep 29 '16 at 6:28
  • Thank you for your advice! But I want to use cuda and tensorflow. So I should install nvidia driver T.T – MTHL Sep 29 '16 at 6:33
  • That advice is only from my personal experience, maybe there is some way out. :) Good Luck. – Mustafa Yılmaz Sep 29 '16 at 6:37
  • I solved it. 1. I connect two monitors to GPU / 2.open NVIDIA X Server Setting (X-server Display Configuration) – MTHL Sep 29 '16 at 7:09
  • GT-1070 has dual-link? I can't connect two DVI/HDMIs, i'm gonna need a converter i think. – Mustafa Yılmaz Sep 29 '16 at 7:33
