It looks like with 17.04 it should be better. At least all three screens (Optimus in BIOS is on) are working again (as of 2017.03.28).
xrandr | grep " connec" LVDS-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm DP-1-2 connected 2560x1440+1920+0 597mm x 336mm DP-1-3 connected 2560x1440+4480+0 597mm x 336mm The only problem I could see within a few minutes of testing, is that on the primary screen the mouse cursor flickers. Fortunately in this setup it is not an issue for me. Can please everybody test if this issue is really "fixed" for all of us ("This bug affects you and 5 other people")? Should we close this issue then? What actions are still required (incl. crossreporting to other/upstream bugzillas)? Is this flickering on primary screen worth its own bugzilla entry? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1556459 Title: [Lenovo ThinkPad W530] Regression: cannot set up 3 display configuration any more (Optimus) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1556459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
