Ubuntu 9.04 Jaunty & Nvidia video card resolutions

[Alberto1]

Hello,
I've got Ubuntu 9.04 Jaunty + lxde. My video card is Nvidia FX 5200 (Nvidia driver ver. 173.14.18). My monitor is a lcd Acer mod. x193w (widescreen). At present I cannot choose the 1280x800 resolution as I was used to when I was using Ubuntu 8.04 Hardy. Nvidia X Server settings offers several resolutions (included the native monitor resolution, 1440x900) but not 1280x800 as before. I wonder why. I even added mode 1280x800 in the Section "Screen" of xorg.conf but it was ignored.
Any suggestions?
Best Regards.
Alberto

n the meantime I had a look around in the web and noticed that you can add new ModeLines at your xorg.conf into the Section "Monitor", then into the Section "Screen" you have got to add Modes where you put the same resolutions you have put in the ModeLines that you have just added. So, by means of the Free86 Modeline Generator ( http://xtiming.sourceforge.net/cgi-bin/xtiming.pl ) I prepared this ModeLine: ModeLine "1280x800@60" 83.91 1280 1312 1624 1656 800 816 824 841. Now 1280x800 is available and works but there's something wrong about it, as, if I select it, not all the image is visible. It seems that the image is a little larger than the screen dimensions, and for this problem I don't know what to do, yet (By the way, have you got a suggestion?)
Best Regards,
Alberto

Try removing the line that says "Virtual" under the Display subsection of your xorg.conf

that one always bugged me as I can't think of why someone would want that 'feature'
