Kubuntu resolution stuck at (800x600) in VirtualBox

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

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.

Looks like i have fixed it: I have changed the VirtualBox Graphics Controller to VMSVGA - started Kubuntu again and this time it was accepted higher Resolutions and kept them.
