Ubuntu 5.10 is installed along with WinXP-Professional which came pre-loaded. (Straight install of UBUNTU from the source disk) and with `grub` boot loader.

The screen suupports 1024x768 and 800x600.

When I first installed UBUNTU, and after creating the users, the system automatically gave the correct (higher) resolution.

However, after the first cold boot, I noticed the following.
(1) System defaults to 800x600. (Even the login prompt). Once logged in, the configuration option in the menu (preferences-->screen resolution) does not allow other entries.
(2) Now when I go in to System-->Login again menu and login as the same user, it magically reverts to the correct resolution. (Including the login prompt).

This tells me that the boot process alone has a problem. How and what do I change to correct it?

Could somebody point me to which file(s) to correct?

There could be something wrong with your /etc/X11/xorg.conf. Try posting the contents of that up here.

Here is /etc/X11/xorg.conf

***********************
Thanks.

It looks as though it's okay. You could try regenerating it with the command 'sudo dpkg-reconfigure xserver-xorg'.

Try editing your config and change "i810" to "vesa" and reboot. This seems to fix my problem in Xubuntu.

Thanks a lot for the help. Changing the entry in the section gave the right result. But some real crispness was lost and I think that the font defaults in open office changed (possible?).

End

The Vesa is a generic video driver. That's why you probably noticed why it wasnt so sharp anymore, but atleast it works. Keep hunting around im sure someone will find a solution the problem oneday.
