Hi, i also have the X1 and i had the same problem today.
When my X1 didnt have an external monitor attached, everything was fine. When an external monitor in, everything went black (but mouse cursor visible). I had PhpStorm open.. so i closed it and tried again and it worked. Afterwards i could open PhpStorm again and everything was good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849484 Title: [X1 Carbon 7, i915, HDMI] Ultra-wide monitor recognized properly when plugged in only intermittently [Xorg only] To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1849484/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
