I just gave nouveau a try and was surprised that it just works out of the box on Mandriva. Great work! However, I'm not sure how to set up a different resolution properly. With the closed nvidia driver, I usually just click on krandrtray in KDE and pick a different resolution. With nouveau driver, though, it works as well, but only partially. I can see the resolution is theoretically changed (fonts, windows are bigger when I change from 1280x1024 to 1024x768), but technically, in my LCD monitor info I can see the resolution is still 1280x1024. Why? Because of this issue, I can't use my beamer (dual-head), which only supports resolutions up to 1024x768. -- Tomasz Chmielewski http://wpkg.org

Then xrandr -s [the number of my favourite resolution in the list]. For further information look there: http://intellinuxgraphics.org/dualhead.html (or any xrandr 1.2 tutorial for that matter).

Tomasz, It sounds to me like what may be happening is the video card is doing the scaling instead of the monitor. This is evidenced by the fact that the resolution does change, but the LCD still sees the native resolution coming in. This shouldn't affect dual head, however. I'm not sure how to change this. It's also possible your monitor needs this. This should, however, give you a starting point on where to look for how to correct this. - Michael On Tuesday 30 September 2008 05:19:04 pm Tomasz Chmielewski wrote:> I just gave nouveau a try and was surprised that it just works out of > the box on Mandriva.
