Kubuntu & Ubuntu 12.10 beta2 in my Virtual Box. Then I went o the friend who has a Mac and I asked him to run Ubuntu on his Mac. Unfortunately he had'nt VirtualBox, but Parallels. When Ubuntu boots it shows that the wrong screen resolution (1920x1080) has been detected,
although the Mac is only 1280x800 (poor one :)
We tried several times to adjust the resolution when an idea came to me. It is too simple to adjust the resolution inside the Ubuntu. Just open terminal and type the next commands:
then in the simple nano editor, write (or just paste) this:
Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device"
then save the file using Ctrl+O, then quit Ctrl+x;
Voila - logout and login again and resolution is fixed forever;
Thanks for the great wiki here:
