TNT/GeForce driver for Haiku
Please first verify if the problem you are having is not something that still is on the 'todo' list and that you are using the latest driver.
If it's not on the list and you're using the latest driver, please see if a matching bug report already exists at the Haiku website. If not, or if you are unsure, file a new one. Make sure you are as precise as possible because that will make things easier to trackdown and fix...
