Comment 2 for bug 261613

I dont know if your experiencing the same issue I did, I upgraded blah blah blah, noticed new nvidia in there, didnt think of anything till i restarted.

my settings were lost.

Well.
I fixed the problem by going into hardware drivers, and re-installing, and re-enabling NVIDIA graphix driver 173

I think the problem is when you upgrade/update it rewrites your configs, setting the drivers to default, then when you restart, you get low graphics mode.

ALthough i am not a dev, so I have no clue, i upgraded to see if the new kernel would break usb on hibernate (when hibernate dont even work lol)
