Comment 16 for bug 309482

The kwin issue may be due to trying to use "vesa" (which doesn't support compiz, which kwin requires afaik). But report that separately as it's not an -nv issue.

If you want the -vesa crash investigated as well, file a new bug for that, with a full backtrace of the xserver when running with "vesa" (directions for this are available at http://wiki.ubuntu.com/X/Backtracing).

As far as it not using -nv, it looks like the GeForce 7100 is not listed as supported in -nv yet (despite what 'man nv' seems to claim). So yes this hardware will require using -nvidia for now. You can see what pci id's that the -nv driver supports by looking in /usr/share/xserver-xorg/pci/nv.ids. You can also try forcing it by inserting "10de016a" into that file; no idea if that will work though.

Anyway, that third issue is indeed an -nv problem, so we'll focus on that for this bug report.
