Increasing the screen resolution of Ubuntu-7.10 on VirtualBox

Oops...finally i managed to configure my ubuntu screen resolution to the fullest.

I have a Dell Vostro 1400 laptop with Windows xp professional. Ubuntu runs on my machine on top of VirtualBox.

But I never enjoyed working with ubuntu, since all i was able to view the ubuntu desktop at the resolution "800x600" only.

After searching through the web, I finally managed to get the full resolution supported by my notebook. (1280x800).

These are steps i followed:

- installed the virtual machine add-ons provided by VirtualBox
- opened the /etc/X11/xorg.conf file and added the the resolutions "1280x800" and "1024x768" under the "Screen" section...

So here is how my xorg.conf file looks now...

----------------------------------------------------------------------------------------------
# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

And the only change i made was here:

Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Modes "1280x800" "1024x768" "800x600"
EndSubSection
EndSection

I just added "1280x800" "1024x768" under the SubSection "Display".

Fortunately this worked for me.

(Note: I actually got this information from a VirtualBox forum thread and I sincerely thank the guy who provided this information. Thank you very much really)

Whatmore, if you choose the "Full screen mode" in VirtualBox, you get a feeling of just running ubuntu...

Ya, now i feel, i can slowly leave behind windows xp behind me...
