Well, I've got a second friend who has Ubuntu 7.04 on his laptop now. Everything was beautiful until he asked me to enable TV out. After hours of searching for a method, I found out that the 9100 and 9200 occupy a no man's land in driver country: The open drivers support them well, but don't do TV out, the new proprietary don't support the chipset anymore, the older proprietary drivers support it but only in limited 2D capacity -- no 3D and no TV out, and the patch to the Open Source drivers which someone created from the Gatos project is out of date and no longer builds. I worked for hours on getting the Gatos patch to work. Ugh!
I don't know what to tell my friend. I'm sure someone could get the Gatos patch updated, but my limited scripting skill don't transfer well to video driver programming in C. I think he may never get the TV out to work, in which case he'll be headed back to WinXP.
