Unable to change resolution on OEL8

[TristanP]

Hi - I'm running Oracle Linux 8.10 on Virtualbox 7.2.4 r170995 with my host being an Mac M4 Pro.

My VM is running in graphics mode QemuRamFB with 256MB memory.

Guest additions is installed fine and everything works except I am unable to change the resolution.

I've tried adding new modes using cvt and xrandr and manually creating an xorg.conf file but nothing I tried works.

Here is the output from xrandr:

Code: Select all

[oracle@localhost ~]$ xrandr --verbose

        v: height  800 start    0 end    0 total  800           clock  76.00Hz

I found this old post from a year ago with the exact same issue, but no answer:

viewtopic.php?t=113386

I just have this one resolution listed:

download/file.php?mode=view&id=55437

Anybody know how to solve? Thanks
