I am having the same issue under 16.10 running 4.8.0-34-generic on an X230. BIOS is latest:
G2ETA7WW (2.67 ) 09/09/2016 X fails to start if I have both a VGA and mini DP (active clock, to DVI adapter) external monitors connected. I can use 2 external displays if I disable the LCD screen. I do not have a dock to test using 2x DVI or HDMI and not VGA. Trying to enable all 3 displays results in "Could not switch the monitor configuration could not set the configuration for CRTC 65" (or 64). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1409166 Title: Popup dialog "could not set the configuration for CRTC 65" steals keyboard, hinders login in 3-monitor configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1409166/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
