[mandriva] Widescreen (15:9) Laptop Display Settings - cannot set resolution properly


Hi all.

I have tried numerous Google searches to resolve my problem. Some results are half helpful but I feel my problem may have two causes where other people have only had one cause to it!

Basically, I have a laptop with a 15:9 screen that is capable or running at 1280x768 rather than the usual 1024x768. In both the monitor and display configuration I have tried setting the resolution to 1280x800 and 1280x768. Both attempts result in the screen resolution staying at 1024x768, however, the "desktop" if you like is at 1280x768 and so the display cuts off the sides of the desktop unless I scroll across with the mouse.

Search results I have found suggest editing the xorg.conf file, and one instructs use of a modeline calculator. I have tried this and still dont seem to be getting anywhere.

Perhaps I have missed something?

Thank you to anybody that can offer help!

Steve

Check out 915resolution utility

Your display driver supports only the resolutions that are stored in video bios. Recent Xorg drivers do not patch the resolutions in the video bios.

Do a google search for "915resolution" and you will find the tool and instructions how to use it. (I would post the link, but since I'm new to the forum, system won't allow me post any links - I wonder what is the point in that??)

Thank you for this advice, I have now got it working exactly as I wanted it.

Thanks again!
