Yesterday I noticed: my external video-output couldn’t accept the 1600×1050 resolution anymore (magically because it worked some time ago). So I started some unsuccessful searches along the google to find a possible solution. But.. the google doesn’t help me!

So I took more attention to my /var/log/Xorg.0.log and I see into it my video ram size reported wrong! My onboard video card just can provide 128MB of shared memory. But the Xorg log reported as 512MB! Uhhh, crazy! Another strange situation was about the EDID, my Xorg doesn’t report the EDID of my 22" LCD TV-Monitor correctly anymore. I don’t know why.

Then.. I just filled my /etc/X11/xorg.conf in the Device and Monitor section with:

My problem was solved. Probably there’s a bizarre bug in the Nvidia proprietary driver! Anyway the NV free driver doesn’t work with two monitors side-by-side (fist in 1600×1050 and second in 1280×800), so I must to use the proprietary driver unfortunately.
