I know similar questions have been asked before about setting the VirtualBox guest resolution, but I haven't been able to find an answer to my custom case.
I've installed VirtualBox on my Windows 7 laptop, and I'm trying to run Kubuntu as a guest. The windows resolution is 1366x768, and I'd like to have Kubuntu use the same resolution when in full-screen mode.
I have successfully installed the Guest Additions package. This lets me configure various high resolutions, but none of them are 1366x768.
I'd like to know if it is possible to add such a custom resolution to Kubuntu. In the old days, it was possible to edit xorg.conf, but I guess that file is no longer created.
I also tried to run "VBoxManage.exe controlvm Kubuntu 1366 768 32" from the host, but this didn't seem to do anything.
