[Bug 1941937] Re: kubuntu focal.3 no wallpaper on one display, right-click not working on that display

Sat Aug 28 04:07:17 UTC 2021

** Description changed:

  ** Background

  Performing a QA-test install (Lubuntu impish) to
  - hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)

  testcase: install using existing partition (sda1)

  On the box existed
  - Lubuntu focal.3  (system selected for replacing with impish)
  - Xubuntu focal.3  (an install-alongside or auto-resize QA-test)
  - Kubuntu focal.3  (another install-alongside/auto-resize QA-test)

  I'm booting the Kubuntu focal.3 expecting no changes.. The QA-test done
  days ago was good and I passed it without issues. This will be it's
  first login after that initial-post-install checks where I noticed
  nothing wrong.

  ** What I see

  My displays are setup to match my config (one display set above the
  other), however

  wallpaper on my.bottom display is present & looks normal

  NO WALLPAPER appears on my.top display

  right-click on my.bottom display is pulling up menu allowing me
  Create.New..Configure.Desktop as expected.

  right-click on my.TOP display however does nothing

  Moving windows around is perfect..

  ** ACTUAL BEHAVIOR

  Wallpaper on both monitors, not just my.bottom display
  Right click of background pulls up menu on both displays, not just my.bottom

  ** EXPECTED BEHAVIOR

  Wallpaper on both monitors, and right-click works both displays.

  (It did this in the initial boot after QA-test install; this is now 2nd
  boot of system which is first time I've noted this behavior)

  ** Note (LXQt has exhibited same behavior in focal)

- I've had this behavior before with LXQt & I can't recall if this was put
- down to an issue in Qt 5.12.8 (fixed in later releases), or openbox
- (which won't apply here of course), but I've not time to chase up the
- bug report I'm thinking of currently sorry.
- 
+ This thought is likely red herring - it reminded me of https://bugs.launchpad.net/openbox/+bug/1845756 which is tagged against openbox thus doesn't apply here. Originally I said "I've had this behavior before with LXQt & I can't recall if this was put down to an issue in Qt 5.12.8 (fixed in later releases), or openbox (which won't apply here of course).."

  I'll complete this QA-test and aim to return and add more later.
- This box is only used for QA-test installs, so system may not exist for very long.  It's likely more useful if I repeated this with Kubuntu impish, but I suspect it won't be created (esp. if related to the Qt 5.12.8 bug I've alluded to earlier).. the Lubuntu issue this reminds me of doesn't occur in later releases.
