Could you please test if this is still occurring for Gutsy-final? It's possible this may have been due to a bug in xresprobe that was fixed in Gutsy.
If not, are you able to see any other refresh rates beyond 60Hz? If not then this would be a dupe of 27508. If you are able to see other refresh rates, but 100Hz still is not showing up, please attach your /var/log/Xorg.0.log and the output of `xrandr` and `sudo ddcprobe`. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- missing 100 hz refresh rate in the "Screen Resolution Preferences" https://bugs.launchpad.net/bugs/16429 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
