I want to run the guest in 1920x1080 (16:9) so I can easily record screencasts in 'full-hd'.
After deactivating full screen two more options had been added to the resolutions dropdown list, 1920x1200 (16:10) and 1600x1200 (4:3). I then activated full screen mode (host+f) and got the guest running in native 1920x1200 (16:10) for my screen. After installing guest additions the options 1280x960 (4:3) and 1440x1050 (4:3) was added to the list. After installation I had the option of selecting 1024x768 (4:3) and 800圆00 (4:3) as resolution in display settings. I've a 12.04/precise host system and installed Ubuntu 12.04/precise as guest system as well.
There are many questions about resolution issues on askubuntu but no question/solution seems to solve my issue.
