why does my screen resolution keep changing

6.1.6 Guest Additions aren't working correctly with these new kernels, hence the resizing problem when the Graphics Controller in VM is set to VMSVGA. This issue with screen resizing didn't let go of me, so I went and searched on the web some more.įrom what I've read - and with my limited knowledge of inner workings of Linux systems, hopefully understood it at least somewhat correctly - the problem lies in relation between the graphic drivers included in Oracle's VM VirtualBox Guest Additions and the new Linux kernels that came with the recently released version of Ubuntu distro and others based on it. If someone knows how how to remedy the resolution issue with VMSVGA selected as Graphics Controller, I'd love to read it. 6.1.6, Extension Pack (with included Guest additions virtual CD) is also 6.1.6 Leave the option Enable 3D Acceleration unchecked, otherwise VirtualBox will revert the Graphics Controller back to VMSVGA when you confirm the settings.VirtualBox will warn you at the bottom of the Settings window about the invalid settings, you can ignore that. Select VBoxSVGA as your Graphics Controller.Open the Settings for your Ubuntu VM and select the Display section.I had the same problem with the new Kubuntu release.
