Description of problem: Icons are not clickable and contextual menus doesn't work on icons when using dissimilar resolutions on multiple mirrored displays. Version-Release number of selected component (if applicable): gnome-shell-3.32.2-48.el8.x86_64 How reproducible: Always. Steps to Reproduce: 1. This requires 3 monitors to be connected to the system via GPU 2. Set a preferred resolution for display 1 3. Extended the screen area to display 2, mirror display 2 to display 3 4. Set a dissimilar resolution of display 3 from display 2. Example - Display 2 -> 1920x1080 ; Display 3 -> 1920x1200 5. The icons on the extended display (display 2) cannot be clicked anymore. Contextual menus also don't work on the desktop icons. Actual results: The desktop icons cannot be clicked when two mirrored displays are set to display dissimilar display resolutions. Expected results: The icons should be clickable irrespective of resolutions set for each display. Additional info: Read more about issue -> The customer states that they are unable to interact with the icons on the extended display connected to their workstation. The customer's configuration is as such - Workstation with Nvidia video card with three display outputs. Two outputs are used for monitors and the other is used for an IP video encoder. The monitors are laid out vertically. The outputs for the top monitor and the IP video encoder are mirrored so that people who tune in to the video feed can see whatever is displayed on the top monitor. They state that the display which they have mirrored to the IP encoder is causing issues. The icons are visible, but they cannot right-click on them to open them, or left-click on them to get contextual menu.
Can you provide a little more detail on what exact steps the customer is taking to change the resolution as well as mirror and extend the screens? As well, if they're running Wayland or Xorg for this? Wouldn't hurt to know which specific nvidia chip this is either. :) Gnome Settings GUI disables the button that lets you mirror monitors if you have more than 2 monitors, so I assume the customer is using a tool like xrandr or some kind of monitor config. I did check this on gnome-shell-3.32.2-48.el8.x86_64 with a fresh RHEL 8.7 image by extending and mirroring the monitors using xrandr, but I couldn't seem to reproduce the issue. Having a clearer idea of what the user is doing specifically would be very helpful!
Setting needinfo for the above and I would also asked you to attach the customer case to the bug.
Hello, I am the customer who opened the case with RH. The case number is 03538549. We are running Xorg and configuring the displays in xorg.conf. We have a /etc/xdg/monitors.xml in place to make sure what is set in xorg.conf cannot be changed dynamically. The GPUs are NVIDIA A2000. Lots more details in the case. I'm here if more info is needed. Thanks.
