Hello People,
I have an IBM thinkcentre with P4 2.6GHz, dual boot with Win XP and Ubuntu 5.04. My graphics card is Intel 82845GL with 64MB of Video RAM. I have installed and re-installed Ubuntu but my screen is always stuck at 640x480. My machine can support a max resolution of 1024x768. I have tried so many things to get this OK but none have worked. I tried chaning driver to vesa, I wrote all the correct info about my moniter's refresh rates into my xorg.conf file. Nothing seemed to work. Everytime, it would say X server failed to start and I will have to load the backup.
Here is the content of my xorg.conf file:

# /etc/X11/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 /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/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

I found this link which supposedly gives the driver of my graphics card for linux. I downloaded it and tried install it but couldnt. I cant post the link of that site as I havent yet made 5 posts. But it can be found in ubuntuforums.

Please help me with this.
Thanks,
sudarshan.

This may sound weird but have you tried changing your "DefaultDepth" to 24 instead of the current 16? I've that sometimes this could cause issues with screen resolution problems. Give that a shot. I also noticed something else about your xorg.conf file that doesn't seem quite right. In your device section you have the following

Where the bold is the driver that your graphics device would like to use. Yet in your module section that driver doesn't exist

So what I would try and do is put a line that says Load "i810" in there. Make sure though that you remove any current references to another driver. It looks like "int10" could be a video driver so you may want to comment that line out temporarily. I hope this helps. This is all I could come up with. Good luck.

Thanks,
I will try to include the driver thing. wrt defaultdepth, I already tried it. Didnt work.

will this make a difference: https://wiki.ubuntu.com/i915Driver

and this: http://users.skynet.be/thomasvst/linux-on-laptop/#wide

I am not sure if these links will help; but it sounds like a patch problem. BTW, is there a reason for using the hoary? Le us know if this helped or not?
