Cannot change screen resolution


Hi,
I cannot change my screen resolution from 800x600 to 1024x728. I'm using redhat 9 and I have a GeForce 440 MX 64mb VGA card.

Please help

OK. LCDs usually have a 60Hz refresh, so that should be cool.

Open /etc/X11/XF86Config in the editor of your choice.
Look for a line (or more probably two lines) that look like:
Code:
Modes    "800x600" "640x480"
and change it (them) to
Code:
Modes    "1024x768" "800x600" "640x480"

I got it to work. I actually did add 1024x728 and 1024x768 into the XF86Config file. I selected 1024x728 insteadof 1024x768 and that's why it wasn't working. So basically my monitor doesn't support 1024x728. Thanks for your help

Here is my XF86Config
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Generic Laptop Display Panel 1024x768"
HorizSync 31.5 - 48.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "nv"
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce 4 MX (generic)"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "1024x728" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x728" "800x600" "640x480"
EndSubSection
EndSection

I can't get KDE 3.3 to display the 1280x1024 resolution. I have an AOpen 17" LCD. The only refresh rate I have available is 73Hz.

The video card I have is the nVidia GeForce FX5600. I am using the driver nVidia provide on their website as well.

Hi.

Do you mean the only refresh rate your monitor can physically do is 73Hz, or is that the only rate you're able to get?

I don't think anything supports 1024x728, sounds like a typo'd resolution.

ilikejam: That is the only option that KDE gives me. In Windows I use 60Hz on 1280x1024.

Hi again.

Open /etx/X11/xorg.conf, and look for the "Monitor" section.
Change:
Code:
HorizSync xxx - xxx
VertRefresh xxx - xxx
to:
Code:
HorizSync 50 - 70
VertRefresh 50 - 70
Then look for the "Screen" section, and change the 'Modes' line(s) so that they read:
Code:
Modes "1280x1024"
Then restart X (log out, then back in, or maybe even reboot), and you should be in 1280x1024 at 60Hz. Hopefully.

Dave
