[Bug 1942427] Re: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915
Update: after upgrading to 21.10 (Linux 5.13.0-21-generic #21-Ubuntu SMP Tue Oct 19 08:59:28 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux) the problem persists with a twist: The settings applet now sees all monitors, but trying to configure a setup with all three is not really feasible since selecting a setup leads to both external monitors going blank and the primary screen dimming, with no visible dialog for confirming that the new configuration is to be applied permanently (possibly displayed on one of the two blanked-out monitors). I hope this bug will be addressed shortly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942427 Title: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The system now runs 5.11.0-34-generic which still has the bug. Looking in my /boot the oldest I have is 5.11.0-31-generic which introduced the bug as far as I can tell (thanks apt autoremove). I do however update whenever the thing prompts me to so I would venture a guess that whatever preceded 5.11.0-31 worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942427 Title: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I would urge you to reconsider the importance of this bug.

[Bug 1942427] [NEW] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915
Public bug reported: upgrading to latest packages, my setup with 3 displays (internal plus 2 external, plugged into Lenovo USB-c base station) no longer works. the Settings -> Displays app does find all displays, but the system only displays on the internal one. Attempting to enable all displays fails, the third disappears from view in the Displays app just before it presents the "Keep settings" dialog. However no output appears on any of the external displays other than the display's own firmware messages.
