Ubuntu Natty 11.04 and Dell Latitude XT

Just got my Dell Latitude XT from eBay and now trying to make it do everything i want.

So far:
Natty installs pretty easy, pen and single touch works out of the box.

Problem 1:
No bootable device, but if you select F12-Boot menu and select hard drive it boots

Solution:
Go to BIOS and in Boot-Order make sure you activated the harddisk with "space". You will see a number displayed in front of the device name if its activated

Problem 2:
Multitouch does not work.  If you type "xinput --list" in a terminal, just touchscreen is displayed, not multitouch. This means, firmware is not up to date....

I am installing Win7 right now to update the firmware and then i will report.

So... took a while, but was worth it. I installed win7, had to perform a BIOS upgrade and then installed the latest Ntrig drivers from the dell website. I rebooted twice to be sure and then started natty live cd and... tada! multitouch is working. If you type xinput --list you see now there is the multitouch screen recognized and moving the window with 3 fingers works.

Problem 3: Multitouch screen somtimes makes random mouse clicks !!!

Solution:
1. Upgrade firmware to the one from the Ntrig website for latest windows 7 (not the dell website) So, currently im using Firmware 4.9.15.13.7 instead of  4.5.2.3.5.
This alone doesnt remove the mouseclicks, but now the ntrig-calibrator from: https://wiki.ubuntu.com/Multitouch/Calibration/Ntrig

works. So if the mouseclicks appear, run the calb.sh as root and dont touch the screen while calib is running. Afterwards it works like a charm.

Problem 4: Unity sucks! its not that bad, but it always crashes.
Solution: install gnome3 (warning, this will make unity unusable, and its also not that stable, so its just if you really want gnome3) You will find the commands at google, basically install the gnome3 repository and upgrade and install gnome-shell.
Then use ginn for customizing your gestures... works good as soon as you experiment with the "gesturetest" utility and write a nice wishes.xml

Problem 5: ginn crashes on java applications (at least jarnal doesnt work)

Solution: still looking for it ...
