linux – Can’t resize screen in VirtualBox

admin

I am using an Arch Linux VM in VirtualBox in Linux Mint 22.1.

Currently, the Arch Linux is not installed and I am using the Arch Linux installation ISO, so I can’t do much.

While the VM is running, in VirtualBox when I go to View > VirtualBox Screen 1, all “Resize to x” options are greyed out and I’m stuck on 1280×800. Since I use a 1366×720 Laptop, this is pretty annoying. I have tried several things:

  • Going to File > Preferences > Display and changing Maximum Guest Screen Size: That doesn’t do anything.

  • Changing Graphics Controller from VMSVGA: That does fix the issue, but it only introduces more issues that are worse. (e.g. Holding Enter causes not only VirtualBox but my entire computer to freeze, even if I don’t allocate much RAM.)

  • Installing Guest Additions: I’ve tried, but I just can’t do it. I’ve tried pacman -S virtualbox-guest-iso, that did nothing. I’ve also tried Devices > Insert Guest Additions CD image, but it doesn’t find the disk image file, and when it asks me to download it from the Internet and I click Download, it gets stuck at 100%.

Can someone please tell me how I can fix this issue? Or at least install VirtualBox Guest Additions?
