And here's X logs from around the same time: [ 520.969] (II) intel(0): resizing framebuffer to 3120x2751 [ 521.017] (II) intel(0): switch to mode 1920x1200@60.0 on DP1-1 using pipe 0, position (1920, 0), rotation left, reflection none [ 521.420] (II) intel(0): switch to mode 1920x1080@60.0 on eDP1 using pipe 1, position (0, 1671), rotation normal, reflection none [ 522.460] (II) intel(0): switch to mode 1920x1200@60.0 on DP1-8 using pipe 2, position (0, 471), rotation normal, reflection none
Something else interesting that I just noticed is that while the 3rd monitor has no image, it's there as far as X is concerned. Eg, I can mouse over to it, I can move windows to it with my window manager's shortcuts. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1104230 Title: DisplayPort 1.2 MST support is missing in the Intel driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1104230/+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
