I have been trying this for a while but no luck. I installed
ubuntu-11.10-desktop-i386 twice. Also installed guest additions. However I always get maximum screen resolution as,
1024 x 768.
Do I need to change anything in
/etc/X11/xorg.conf file (example) ? Presently there is no such file in that path. Also, please let me know what should be contents of the file for 11.10 version ? Thanks.
