As said all works fine except for the screen that looks blurry. The LCD has a native resolution of 1400x1050 pixels but I could only configure a resolution of 1280x1024 with the 'System|Preferences|Screen resolution' tool. Searching the forums gave me the solution. See this thread http://ubuntuforums.org/showthread.php?t=27029&highlight=i810
So I downloaded the 855resolution from http://ftp.psn.ru/debian/pool/main/8/855resolution/855resolution_0.3-4_i386.deb and installed it.

Following the instructions from the forum thread did not really work for me. I discovered the trick is to stop X (GNOME/GDM) before running and configuring. Here are the steps I performed:

1. ctrl-alt-F1 to switch to a terminal
2. login
3. sudo /etc/init.d/gdm stop to stop GNOME
4. sudo /usr/sbin/855resolution -l to get a listing of possible resolutions. See the output.
5. sudo nano /etc/default/855resolution to put in mode 5c and resolutions XRES0=1400 and YRES0=1050. The mode is can be different for other systems so do check what your mode belongs to your wanted resolution.
6. sudo /etc/init.d/855resolution start to commit the settings
7. sudo dpkg-reconfigure xserver-xorg to reconfigure X and make sure you select the i810 driver and as maximum resolution the 1400x1050. Set your monitor also to 1400x1050@60. This is my xorg.conf file.
8. sudo /etc/init.d/gdm restart to start GNOME again.
9. ctrl-alt-F7 and you should see a clear screen.
10. I did not need to do anything special to keep this result after rebooting.



btw: `915resolution' is the successor of `855resolution'
