Kubuntu resolution stuck at (800x600) in VirtualBox

Question

Linux newbie - I have recently installed Kubuntu into VirtualBox (on my laptop) to play around with, but I cannot get Kubuntu to go to a higher resolution.

VirtualBox setup:

Base Memory = 4gb
Video Memory = 64Mb
Graphics Controller = VMSVGA

Any suggestions would be greatly appreciated cheers

Looks lke i have fixed it: Changed the VirtualBox Graphics Controller to VBoxSVGA - started Kubuntu again and this time it was accepted higher Resolutions and kept them. — Smac, Jul 25 '19 at 07:03
Switching the VirtualBox Graphics Controller to VBoxSVGA also fixed things for me. (I've never had this problem before with Ubuntu, first time I've install Kubuntu) @Smac - could you add you fix as a answer, then it can be upvoted. — Tom, Jul 28 '20 at 18:12

Just right click on the image of the monitor in the bottom right of your running VM and then change the resolution to the desired one.

I struggled too to figure it out ;)

Did you try to install the VirtualBox's Guest Additions CD image? This can resolve your problem I think.

If you didn't install it, follow this procedure:

Run your VM.
Then go to the Virtual Box's menu and under Devices select Insert Guest additions Cd Image.
Once the Image is inserted, go to /media/<your_user>/VBox_GAs_6.0.14/ and run the script VBoxLinuxAdditions.run with root privileges (sudo).

After the script execution your VM will (normally) adapt the resolution automatically.

Good answer. Note that VBoxLinuxAdditions will require gcc to be installed. You can install the most essential and used build tools using `sudo apt install build-essential` before running the script. – Mooncake Oct 30 '20 at 11:11
