At at certain point enabling Mirror Display with another monitor will result in a crash.

test expression

```nix with import {}; let switchboard = enableDebugging (pantheon.switchboard.overrideAttrs(old: rec { mesonBuildType = "debug"; })); switchboard-plug-display = enableDebugging (pantheon.switchboard-plug-display.overrideAttrs(old: rec { mesonBuildType = "debug"; })); switchboard-wrapped = pantheon.switchboard-with-plugs.overrideAttrs (old: rec { paths = [ switchboard switchboard-plug-display ]; }); in switchboard-wrapped ```

Steps to reproduce

  1. Build and execute the test expression
  2. Connect another monitor through some means
  3. Switch on Mirror Display The display will be mirrored momentarily.
  4. Crash :boom: :car:

It's possible that this can be observed in different steps.

I have no issue with mirroring, but switchboard crashes, when it is opened (even in the overview) when i connect an external display to my notebook.

Since it's the same error, it's probably also the same problem.

Hardware is a Lenovo ThinkPad X230 with intel integrated GPU.

I've seen this recently so it's probably not related to mirroring display.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

  1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
  2. Ask on the NixOS Discourse.
  3. Ask on the #nixos channel on irc.freenode.net.

Probably fixed?

davidak commented 1 year ago

Yes. It does not crash. (It's still not working great https://github.com/elementary/switchboard-plug-display/issues/273)
