Description Toni Helenius 2008-12-04 08:27:07 UTC 
Version:            (using KDE 4.1.3)
Installed from:    Ubuntu Packages

I attached TV to my computer. KDE didn't give any options in System Settings, just said I have one display. Even after reboot (after reboot it changed my TV to default display and my monitor off, no matter which of the 2 sockets I used).

I configured the displays with the NVIDIA tools. Some configurations didn't work at all, plasma crashed or corrupted. I finally found something that could. Extended display, dual-view in Windows (?).

But to my horror KDE thought that I was now using one display with monstrous resolution, 1600x1200 + 1024x768. Which is kinda correct, but it made all font scales and whatnot so small that it was barely readable.

This shouldn't happen? Only option to get this work, was to set the TV disabled. Which is not an desired option...

It looks like this is not really related to the KDE display settings.

If your TV was not detected once you plugged it in, it probably means that the video driver is not handling it using the X RandR extension.

As you mentioned you used some NVIDIA tools to configure the display, the configuration utility probably set your displays as a twinview (or xinerama) big panel, which is a setup that we can't really manage through krandr.

Just to make sure this is the case, can you please post here the output of xrandr when the display is set to the monstruous resolution?

Thanks in advance

Yeah further investigations of this matter reveal that neither the free NV nor the NVIDIA's propriety driver fully supports XRANDR extensions. And these are required by the KDE to configure the display settings. Am I right?
Comment 4 Gustavo Pichorim Boiko 2009-01-22 16:47:03 UTC 
Yes, usually if the display output is named as "default" in the xrandr output command it means that internally the driver only supports randr up to 1.1

There is not much we can do. krandr will work properly if the driver supports randr 1.2

So I'm closing this bug as INVALID.

Thanks for your report.
