Hi all,
I'm trying to get my Toshiba 32WLT66 LCD TV to run at its native resolution (1366x768), or as close to that as I can get (1368x768), connected over a DVI-to-HDMI cable.
I'm trying to do this using the modeline at

The EDID data the TV is giving appears to be failing to return the native modes, and consequently nvidia-settings doesn't list it as a possible mode. The highest I can get is 1280x720 (which nvidia-settings appears to think is the monitor's native resolution).
Until last boot I was getting "No valid modes for 1368x768" when I examined my Xorg.0.log. I used nvidia-settings to tweak my xorg.conf so that 1280x720 was my default resolution (otherwise I was stuck in 800x600 hell), and now restarting X with logverbose 6 it doesn't seem to even attempt to validate the mode.
I've tried using "ExactModeTimingsDVI" "true", but that causes the monitor to go black on restarting X.
I've also tried the ignore EDID options, but they either make no difference or cause the display to drop back to 640x480 (as was teh case when I was using the nv driver; I had to use an alternative text-mode install CD as the GUI wouldn't run at >640x480, and the install window wouldn't fit on the damn screen).
Running Kubuntu Feisty Fawn with kernel 2.6.21.5 and nvidia driver version 100.14.11. Bug report log is attached in a tar.bz2.
Thanks,
Ed
