I am trying to determine why the host Linux OS is freezing while I’m running VirtualBox. The latest attempt is restoring the default display resolution for the host OS to 1920x1080.
I am able to successfully enlarge the VBox display resolution for both Plasma VBoxes (Cooker and Rolling), but have been unable to get the same (custom) resolution it’s using, for the Xfce Vboxes (also Cooker and Rolling) to persist between sessions.
I found directions on these two pages (which apply to Ubuntu - which is not the host OS):
After installing and running the
cvt command for the display resolution, the first two xrandr commands on each page, will add the resolution, 1680x931, which is what the OpenMandriva Plasma VBoxes now use and can select it in the Xfce Display setting, but the steps to make it persistent between Xfce sessions isn’t working. Once logging out of Xfce and back in, the display goes back to 1440x900. At this resolution, the screen takes up maybe the middle 75-80% of the screen, but if Plasma can natively accept 1680x931, I don’t see why Xfce isn’t. The VirtualBoxes are using the same GPU (VMSVGA (VMware)). Increasing/decreasing the amount of video memory for the VBox does not affect the display resolution.
The prior display resolution for the host when the OS was freezing, was 1680x1050, in which the 1440x900 resolution in the VBox took up more of the screen.
Thanks in advance for any suggestions.
