DELL Inspiron: Problem with projector under Linux

Try pressing CTRL-ALT-+(plus) or CTRL-ALT--(minus)
It should cycle through the available resoltions.

I can't change the resolution with CTRL-ALT-+(plus) or CTRL-ALT--(minus)

In your /etc/X11/XF86Config file there should be a Screen section as outlined below.

What you could try is changing the modes section so only the mode you want is listed, ie "1024x768", and delete "800x600" and "640x480"

Section "Screen"
        ...
        SubSection "Display"
                Depth     24
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection

Good Luck

i have a new 5150 3.20 Ghz p4m HT with the 5200 64mb card

i'm dual booting xp/fedora core(smp), and everything works great, except when i try to switch on an attached monitor.

the lcd jumps down to 640x480 (scrolling 1600x1200) and the second monitor is unreadably jumpy.

i'm using the latest driver installer from nvidia.

i've cut out extraneous resolutions (all but 1600x1200), no dice...

any thoughts?

Hmm your config files look right, I have a friend that has dual screen working happily in fedora on an i5100. I'll see if he has run into these sort of problems before.

i'ld love to know what your friend has done, this problem is driving me nuts. we do a lot a peer programming at our office, and i've had to boot into windows to attach another monitor. don't know if i can do it much longer.... :-)

got it working....

use the 4620 driver instead of the 4496, then add you options for twin view in the screen section

(for the 1600x1200 screen)

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1600x1200"
EndSubSection
Option "TwinView"
Option "SecondMonitorHorizSync" "31.5 - 90.0"
Option "SecondMonitorVertRefresh" "59.0 - 85.0"
EndSection

good to hear :-)
