I have a ThinkPad Ultra Dock 40A2: <a href="http://shop.lenovo.com/us/en/itemdetails/40A20090US/460/6D501EE899104FF9A362D739642CFC27">http://shop.lenovo.com/us/en/itemdetails/40A20090US/460/6D501EE899104FF9A362D739642CFC27</a> <a href="http://support.lenovo.com/us/en/documents/pd029622">http://support.lenovo.com/us/en/documents/pd029622</a> It's got a variety of connectors: VGA, DVI, 2xDP, HDMI. It has a standard and advanced mode that is selectable from the BIOS. I have read that in standard mode only one port is usable but in advanced any ports are. I have mine set to standard. I drive a pair of 2880x1620 displays with a DVI and a DP from the dock. I think the laptop and the dock use MST in order to use more than one display. Before using Linux 4.0 I had to drive one monitor with the dock and one with the VGA connector on the laptop itself. I don't know if nouveau is used for anything, 2880x1620 is mentioned next to intel and nouveau lines in the Xorg.0.log. In the past I did blacklist nouveau.ko once to diagnose the crashing and found that the crashing stopped but I could only get outout on the laptop display. So it seems to be involved somewhere. How does one find out which screen is driven by which card, etc? Thanks for the info regarding runpm, I have removed that option and am running with "nouveau.noaccel=1" now. It seems to be stable as it's up about 40 min so far. I have not used any reverse-prime stuff. $ xrandr Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 32767 x 32767 eDP2 connected (normal left inverted right x axis y axis) 2880x1620 59.96 + 50.00 2048x1536 60.00 1920x1440 60.00 1856x1392 60.01 1792x1344 60.01 1920x1200 59.95 1920x1080 59.93 1600x1200 60.00 1680x1050 59.95 59.88 1600x1024 60.17 1400x1050 59.98 1280x1024 60.02 1440x900 59.89 1280x960 60.00 1360x768 59.80 59.96 1152x864 60.00 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP2-1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 59.99 60.00 50.00 50.00 50.00 59.94 1600x1200 60.00 1680x1050 59.95 1280x1024 75.02 72.05 60.02 1440x900 74.98 59.89 1280x720 60.00 50.00 59.94 1024x768 75.08 70.07 60.00 800x600 72.19 75.00 60.32 720x576 50.00 720x480 60.00 59.94 640x480 75.00 72.81 66.03 60.00 59.94 720x400 70.08 DP2-2 connected 1920x1200+1920+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 59.99 1600x1200 60.00 1680x1050 59.88 1280x1024 75.02 72.05 60.02 1440x900 74.98 59.90 1024x768 75.08 70.07 60.00 800x600 72.19 75.00 60.32 640x480 75.00 72.81 66.03 60.00 720x400 70.08 DP2-3 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) $ $ xrandr --listproviders Providers: number : 2 Provider 0: id: 0x73 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 10 associated providers: 0 name:Intel Provider 1: id: 0x45 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 4 outputs: 2 associated providers: 0 name:nouveau $</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
