Package: arandr
Version: 0.1.9-1
Severity: normal

Dear Maintainer,

   * What led up to the situation?

Connect a projector via HDMI, projector still not powered on

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Started arandr, pushed Apply button

   * What was the outcome of this action?

Error message:

XRandR failed:
XRandR returned error code 1: xrandr: cannot find mode None

   * What outcome did you expect instead?

No error message, but no changes either.

I also tried to save a profile without powering on the device, getting
following exception:

If the issue really only surfaces when the display is disconnected in
suspend, can't be produced otherwise, and as it can then be resolved by
reloading the ARandR state ("new" button or restart ARandR), I'd close
this as out of scope for ARandR.
