Is this still occuring on gutsy-beta?

It's possible this may just be a variant of 27667, in which case the fix for that bug (not in gutsy-beta, but to be released by gutsy-final) will fix this one as well.

I have a nx9010 notebook, and I tried the Gutsy beta Live CD on it. Monitor not detected, display is messed up (screen seems to be too small, and it looks as if a "wave" effect had been applied on it). The system is unusable as it is!

Feisty has detected the display w/o any problems. I could not find any significant differences in the xorg.conf files of my system, and the one used by Gutsy. Monitor was detected as "DPMS" and "Generic".

I have not installed the system to the notebook, only tried the Live CD (I could not installed it even if I had tried, because aside from the windows, I could not make anything out on the screen). I tried the Kubuntu version.

Anyway, I think this bug should receive a higher priority, as it really makes a bad impression, not to mention it prevents the user from installing it.

Hi David,

Can you test Gutsy-final? Like I mentioned, the patch that I think fixes this didn't make it in for Gutsy-beta so you'd definitely have the same problem there, however I suspect it should be fixed in -final. Please confirm. Thanks!

I have the exacly same problem with a nx9010 notebook as David and i use Gutsy/Final.
In my case ddcprobe shows no "monitorrange" at all...

This is fixed since Hardy alpha2, xresprobe is not used anymore so it's up to the driver to get the correct mode.
