Just installed Ubuntu, and writing this post from Ubuntu

The installation was pretty straight forward.
When i booted the OS for the first time, the default resolution was 640x480 and everything was looking crap. Even "Desktop Effects" (3D stuff) was not working.
To add to that the installation had not asked for the root password, so i couldn't change the resolution (it was showing only 640x480).
A little bit of googling saved me. Here's what i did:
1) booted in recovery mode and set the root password.
2) Used this command to set correct resolution (i.e. 1024x768):
Code:
# dpkg-reconfigure xserver-xorg
then i typed "exit" and voila! it presented me with the cool login screen with correct resolution. After that "Desktop Effects" worked fine
Summary: "All's well that ends well"
