I just upgraded to TC 7.0 and got my apps working again, but I'm having an issue with low monitor resolution. The monitor has an optimal resolution of 1920x1080, and I was able to get this in TC 6.x using Xorg with the xf86-video-nv extension. However this extension is not available in TC 7.0, and anyway didn't resolve the problem when I downloaded it from the 6.x repository. Unfortunately I've got a 6 year old box that according to lspci uses an "NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev A2)" VGA compatible controller. Lots of entries in the forum about Nvidia and Xorg but I'm unsure if there's anything worth trying, or what I should try first.
