Hello everybody,

since yesterday I hardly try to configure my Xfree86.
So I used the tool "xf86config" and entered the correct values for my graphic card and monitor.
I have a MSI Geforce4mx graphic card (64mb) and a Samsung Syncmaster 957df. The values for the frequency and sync I took from the samsung website.

Unfortunately when I start KDE, I only can use a resolution of 1024x768 @ 60Hz. But I want 1280x1024 @ 85Hz. What have I to configure to use this settings?

Thanks for help

As part of xf86config, you are asked to specify the set of resolutions that you want to use. (This question is asked for each color depth too BTW). It may simply be that you did not include 1280x1024 as one of your choices

Suggestions:

1. First, pressing "Ctl - Alt - +" simultaneously ("+" is the plus sign on the numeric keyboard) will toggle between all supported resolutions. Do this to loop through the resolutions you've selected. It may be that you just didn't make 1280x1024 the default.

2. If that doesn't work, post the contents of your XF86Config file, which should be in the /etc/X11 directory. Assuming that your card and your monitor are physically capable of supporting that resolution, manually editing the file to include an entry for that resolution is a trivial piece of work. Good luck with it -- J.W.

Hello,

thanks for your reply. Here is an excerpt of my Config-File (unfortunately your hints didn't work):

Does this help?

Hmm - well this looks pretty much OK to me - the only things I'd try doing would be to uncomment the following lines so that they look this way. (Just remove the # sign and any leading spaces) Using your favorite text editor, make these changes:
as well as
Exit X completely, either by logging completely out, or just rebooting. Hopefully that should do it -- J.W.

No sorry, this didn't work. The setting of which component is primarly responsible for the correct resolution? Graphic card or monitor? I never had problems under other distributions like SuSE etc. Unfortunately I never saved the settings in this config file :-((

Sorry it didn't work. I'm not sure what the issue is, because everything looks to be in order in your XF86Config, and so long as your video card and monitor are physically able to support that resolution, things look OK, at least to me. As for your question, in the XF86Config file, the default resolution is determined by the "DefaultDepth" setting in the "Screen" section (which is 24) and then the first entry in the "Modes" line corresponding to that depth (which is 1280x1024).

The only other thing to try I would try would be to set the DefaultDepth to 16 instead of 24, then exit X completely, startx again, and see if that makes a difference. Hopefully others will have other suggestions. Good luck with it -- J.W.

Hi J.W.,

it works now. I had two Device-entries in the config-file:

Section "Device"
Identifier "Standard VGA"
VendorName "Unknown"
BoardName "Unknown"
Driver "vga"

EndSection

# Device configured by xf86config:

Section "Device"
Identifier "nv"
Driver "nv"
#VideoRam 65536
# Insert Clocks lines here if appropriate
EndSection

When I comment out the "Standard VGA"-device, everything works perfectly. I lost sight of this, sorry.

Thanks so much for you help.
