Mouse does not work in AppVMs on rotated monitor

[davidad]

Qubes OS version:

R4.0

Affected component(s):

Probably related to qvm-start-gui --notify-monitor-layout

---

Steps to reproduce the behavior:

• Install Qubes R4.0
• Attach an external monitor
• Rotate the external monitor with xrandr --rotate left
• Launch Firefox in an AppVM
• Move Firefox window to external monitor
• Click inside the Firefox window

Expected behavior:

Firefox responds to mouse activity

Actual behavior:

Firefox does not receive mouse events correctly

General notes:

If I don't rotate, mouse works fine, and xrandr output in the AppVM looks like

Screen 0: minimum 64 x 64, current 7680 x 2160, maximum 32767 x 32767
DUMMY0 connected primary 3840x2160+0+0 325mm x 182mm
   QB3840x2160   23.10*+
DUMMY1 connected 3840x2160+3840+0 650mm x 365mm
   QB3840x2160   23.10*+  23.10* 
   QB2160x3840   59.98  

With rotation:

Screen 0: minimum 64 x 64, current 7680 x 2160, maximum 32767 x 32767
DUMMY0 connected primary 3840x2160+0+0 325mm x 182mm
   QB3840x2160   23.10*+
DUMMY1 connected
   QB3840x2160   23.10 +  23.10  
   QB2160x3840   59.98  

Also, running qvm-start-gui --notify-monitor-layout doesn't seem to have any effect.

I have the same issue, even without rotation. I have a layout, where the primary display is at an offset in the virtual screen, when adding a second monitor. Basically the primary monitor is to the left, but shifted down with --pos 0x520 and the external monitor is moved to the right with --pos 1920x0. Clicking only works in the upper half of the primary monitor, ie. on the originalSize-520 top pixels.

This is my full xrandr line (generated by arandr): xrandr --output HDMI-1 --off --output eDP-1 --primary --mode 1920x1080 --pos 0x520 --rotate normal --output DP-2 --mode 2560x1600 --pos 1920x0 --rotate normal

The app vm sees:

Screen 0: minimum 64 x 64, current 1920 x 1080, maximum 32767 x 32767
DUMMY0 connected primary 1920x1080+0+0 325mm x 182mm
   QB1920x1080   46.10*+
DUMMY1 disconnected
   QB2560x1600   59.99  

ie, the pos is missing and the second monitor appears disconnected.

I also have this issue without rotation. However, it only affects AppVMs that were started before the monitor was plugged in.

Going through the logs, I suspect this error is related:
