I have a panasonic 50'' plasma display with a built in computer.  I have installed Ubunto 8.1 sucessfully but the resolution is limited to 640x480.  The graphics are Intel 855 embeded, and after reading the rather helpful article:

http://absolutebeginner.wordpress.com/2006/07/26/installing-intel-815852855-graphics-controller-drivers-on-ubuntu-debian/

I was able to use alien to convert the rpm to deb and install it.  After restarting I still had a 640x480 resolution so I looked in the Monitor resolution settings

In the settings I now have two screens showing, they are called Laptop(in green) and Unknown(in pink) the resolution for laptop is 640x480 (which seems to be what ubuntu is currently using) and the resolution of unkinow is 1366, 768 (which is the correct resolution for my display)

Obviously been new to Ubuntu I am not quite sure which information is key and which isn't so I have tried to include as much as possible, if anyone understands what I am talking about and or has any suggestions for me that would be great

seems like you need to run from a terminal apt-get install alien

sudo alien <filname.rpm>
sudo dpkg -i <filename.deb>
sudo apt-get update
sudo apt-get upgrade

but download file first (see link below) and then run commands as noted above.

If, in your case you still cant switch to the maximum resolution you should install Intel 915 drivers from the repositories.

Hope this helps.

Hi,  I got called away so sorry for not replying sooner.

The model of my screen is the panasonic th-50phd8ek
When I ran the Intel chip identification software it named the type as

82855 GME

I have already run the following as suggested:

sudo alien <filname.rpm>
sudo dpkg -i <filename.deb>
sudo apt-get update

but I have not run the line

sudo apt-get upgrade:

because last time  I ran the final upgrade statement, it completed the upgrade sucessfully but when I restarted my display went blank as soon as it entered the login screen and never returned.

to clarify, I tried running just the:

sudo apt-get update

without installing the intel driver,  just to check if it was the driver or one of the updates that was causing the problem and the result was the same.  After restart my screen went blank as soon as I entered the login page.  When I pressed ctr+al+ F1 the root prompt came up and I tried resotring the default settings using:

dpkg-reconfigure xserver-xorg

but with no sucess. So I am reluctent to go down this root again as I ended up reinstalling last time.

why not remove the 8255 .deb files you created and installed , then start over with a different chipset like the 915 chipset? the 915 may work better. <<If, in your case you still cant switch to the maximum resolution you should install 915resolution from the repositories. >> 

http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=1764&OSFullName=Linux*&lang=eng&strOSs=39&submit=Go!

to remove the drivers/package try:
" apt-get --purge <name of package you made with alien program> "

then do download different chipset link above and run the cmds:

sudo alien <filname.rpm>
sudo dpkg -i <filename.deb>
sudo apt-get update
sudo apt-get upgrade

i purged the original deb as you suggested and then downloaded the files from the chipset link

This gave me a file called: i915Graphics.tar.gz  which i unpacked and ran the contained install.sh file from termainal using the comman: sudo sh install.sh

I then got a message: Welcome to DRI Driver Installation Script and a description of the driver which seems to be correct.  After pressing Enter I get the option to install / uninstall driver and of course selected 2 to install the driver.

I then got the message :  The script will now compile the [: 1361: ==: unexpected operato DRM kernal modules for your machine.

Pressed enter to continue and got:

[: 1361: ==: unexpected operator
[: 1361: ==: unexpected operator

Compiling DRM module..install.sh: 1361: Syntax error: Bad fd number

It then just returned to the standard terminal promt

look inside the README though and see what it suggests. sometimes good pointers are in there.

i would suggest trying this route if you can

./configure
make
make install

There is no readme included in the download, the intel website

http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProductID=1764&DwnldID=8203&strOSs=39&OSFullName=Linux*&lang=eng

says:

Please download the README.TXT, as it is not included in the package

there is no readme file to download though!  I am really starting to rip my hair out now :)

yeah no kidding, me too.

hey i was going to say, why dont you try suse linux as the drivers are made for that distrobution? that way you could download the rpm and do an install. i know this may seem like a workaround but i would like for you to try it to see if that will work.

Ubuntu is based on Debian and that is why you need to use alien prgm to convert from .rpm -- .deb and this conversion process may be corrupting driver.

suse linux can instantly download rpm file along with any dependecy issues.

this may be a better solution for now.

so do you want to try suse just to pete's sake and to see if those drivers will run your computer correctly?

thats ok Susurrus. I am happy that it worked out for you!  

sometimes, its madatory that you choose a distro which has drivers which works with the certain hardware you have. thats a part of the 'lihn-ux' world!

have a good day.
