Monitor out of range after installation [was: ubuntu-users at lists.ubuntu.com]

[Andrew Kane]

Well, it didn't hose my xserver :)
Also, I have more screen resolution options available than before.
Oddly, the Screen Resolution dialog still seems to think this monitor
is only capable of 60Hz vert refresh instead of 160 Hz, but what the
hell, at least it's working, right?

I hope you have equal or better results.
