Posted: Fri Oct 11, 2002 9:38 pm Post subject: X11 display problem |
|
|
Hello! I have installed Gentoo Linux in the last week and have a few questions:
1. How can I find out, what X11 server is being used (I don't mean the version number)
2. Where and how can I specify the X11 server, that should be used?
3. Where can I set up the desktop size?
At the moment X11 starts in VGA mode but with a desktop of 1280x1024 (I guess)
I am using Gentoo Linux 1.4rc1 having a Diamond Viper V770 Ultra graphics card (NVidia Riva TNT2 Ultra Chip), 32MB memory.
Thanks
Christopher |

The configuration file of xfree is located in /etc/X11/XF86Config.
you must check two sections of this file.
#**********************************************************************
# Graphics device section
#**********************************************************************
#*****************************************************************
# Screen sections
#********************************************************************
If you don't want to edit this manuallly you have two options:
1) use xf86config. This is a script that is used to configure the xfree
2)xf86cgf -xf86config /etc/X11/XF86Config. This program run in graphic mode. |

Xfree86-4.x has only one server for all kinds of hardware.
The easiest way to create your configuration is:
It will create a configuration file in your home directory.

I have the same kind of card! You are running that tool as root, right? Anyway, examples are given at the end of this post. Make sure you're using either the "nv" driver (or "nvidia" if you've emerged the official nvidia drivers). Have a look at the "Screen" section of your XF86Config file. The Modes keyword lists the available resolutions. The first listed resolution on a Mode line is the one that will be used by default. In my case, I just want 1024x768 but supposing you had:
Code: | Modes "800x600 1024x768 640x480" |
then all those modes would be available, but X would use 800x600 by default. Maybe that's your problem. The other thing is that if you have not configured your monitor capabilities properly then X might not allow a certain resolution to be used. For best results, look up the vertical and horizontal sync ranges of your monitor model and make sure they're defined in the Monitor section, so X knows exactly what your monitor is capable of. Mine are reproduced below (which is exactly correct for my model of monitor, I got the info off Dell's site). The units are in Hz.
What else? Maybe the amount of RAM available on your video card chipset isn't being correctly detected, though I've never experienced that in practice.
xf86config can help you configure all of this stuff if you'd rather not edit your XF86Config, even if it isn't that user friendly.
BTW, you can switch dynamically between available resolutions with these keystrokes while X is running:
Ctrl / Alt / Num+
Ctrl / Alt / Num-
Examples follow:
Code: | Section "Screen"
Identifier "Screen 1"
Device "Riva_TNT2"
Monitor "Dell_ES17"
DefaultDepth 24
Subsection "Display"
Depth 8
Modes "1024x768"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1024x768"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1024x768"
ViewPort 0 0
EndSubsection
EndSection
Section "Monitor"
Identifier "Dell_ES17"
HorizSync 31-85
VertRefresh 48-100
EndSection
Section "Device"
Identifier "Riva_TNT2"
# Video driver to be used specifed below ...
Driver "nv"
# You can override the amount of RAM X will think your video card has
# This means 32Mb ...
VideoRam 32768
