HI,     I have a config file in /etc/X11/xorg.conf.d to start up DM's on Xorg in 4K monitor resolution, as in F31 both Xorg and Wayland would start up in 800x600 resolution and I would then have to minimize then maximize the VM window for the DM to switch into 4K resolution as I desired. After upgrading from F31 to F32 (there were lots of issues with the upgrade that I will detail in other threads), when the Gnome on Xorg DM starts up (I am using Virtualbox on Wndows 10) I get a message at the top of the DM screen specifying 'VBOxClient: Failed to Register Resizing Support'. What exactly does this message mean? Looking at dmesg I also get lots of the following messages: [ 2457.520753] Service: Shared Clipboard [ 2457.532708] Service: Host Version Check [ 2457.543366] Service: Seamless [ 2457.568504] Service: Drag and Drop (DnD) [ 2457.574146] Service: Display SVGA X11 [ 2457.593861] Running service failed: VERR_RESOURCE_BUSY [ 2458.363216] rfkill: input handler disabled [ 2476.932326] rfkill: input handler enabled [ 2477.087703] A fatal guest X Window error occurred.  This may just mean that the Window system was shut down while the client was still runn [ 2477.088440] A fatal guest X Window error occurred.  This may just mean that the Window system was shut down while the client was still runn [ 2477.089249] A fatal guest X Window error occurred.  This may just mean that the Window system was shut down while the client was still runn [ 2477.089476] Terminating threads ...
