Reproducing this: $ xrandr -d :0.0 --output HDMI-A-0 --left-of eDP $ xrandr -d :0.0 --output HDMI-A-0 --right-of eDP
No problem with: $ xrandr -d :0.0 --output HDMI-A-0 --above eDP $ xrandr -d :0.0 --output HDMI-A-0 --below eDP The affected and unaffected laptops each have identical kernel log entries about IRQ 7 and SADs count so I don't think those are related to this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873895 Title: Regression: block staircase display with side-by-side monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libxcb/+bug/1873895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
