I'm running ubuntu 10.4 on an hp touchsmart 300-1000. The touchscreen is the NextWindow 1900. The touchscreen doesn't work at all. If someone can give me step by step instructions to get it working and the problem is resolved I'll give the "winner" a demonoid invite. It's not much, but sell it on ebay and you could easily get a few bucks. So yeah. First one to fix wins !
