Changing XF86Config file
I need help changing my monitor and GPU settings. Well the problem is that when i boot up linux (redhat 9), i get all the [OK] 's but when it comes to firstboot my monitor switches off. i know how to get in to runlevel 3 and i have read the log file, it states no [EE] files.
When i try to run: /etc/X11/XF86Config it states permission denide. If any one knows how to fix this reply. or If any one how has a GeForce FX 5200. tell me what settings you used at installation. |
Xconfigurator OR xf86config is the syntax you are likely looking for ;)
Cool |
I think in redhat9, you want the redhat-config-xfree86 command. Also you'll need to be root to run the X-configurator. If you can't get any of the graphical configurators to work, you might have to manually edit the XFree86 file. Just make sure to look up the specs and then try a low resolution setting on your monitor, at least till you get X up.

i have tried Xconfigurator, it states that it is not a command and i have used upper and lower case correctly. I have not tried X-configurator.
I tried the redhat-config-xfree86 command and it stated after i pressed <ctrl> <alt> <f1> because my monitor switched off: bogus values id: "sorry i can not remember" name: none Hsync: none Vsync: none I will try X-configurator ut in the mean time does anyone else know what to do? |
X-configurator is the utility that is run by the redhat-config-xfree86 command. So trying to execute the command X-configurator won't help.
Look up the specifications for your monitor in the manual or at the manufacturers website. There are 3 important values you will need: horizontal and vertical refresh rates and maximum resolution. Make sure that you find the correct ones, if you have an older monitor and you put in values that are wrong you could cook your monitor (think smoke and flames). Once you found the right values, open the /etc/X11/XF86Config file using a text editor like pico or vi. Towards the bottom of the file, you will see a section called monitor. You will see places to enter the horizontal and vertical refresh rates. Put in the proper values. It will look similar to this: Code:
Section "Monitor" Code:
Section "Screen" Code:
Section "ServerLayout" Once you have edited the file, save it and try to start the Xserver, using the startx command. Once you get X working, you can change the maximum resolution and color depth to whatever your monitor/videocard can support using the redhat display manager or you can run the redhat-config-xfree86 command. |
Good morning, Capt_Caveman :)
Just a quick one: I want to reduce the refresh rate (from 120 to 90 hz). In what section should I look? I didn't find it like mentioned in DISCUSSION: Configuring XFree86 for a Non-Specific Linux Distribution. (And this guy is looking for it, too Test Hz settings for display). So, do you have any ideas? |
From the other posts, I'm assuming that you want to change the vertical refresh rate. So under the Monitor Subsection of the /etc/X11/XF86Config file:
Code:
Section "Monitor" Code:
HTH |
as i said in your post in http://www.linuxquestions.org/questi...adid=94493,you try 'xf86config'.i am sure that it can solve your problems.

I have changed the monitor settigns,
when i was looking at the videocard settings, they are not the setting i put in. the settings were for the generic vesa card. i have a geforce fx 5200 what shoud i change in the config settings? |
For the Geforce 5200, you want your XF86Config file to look like this:
code:Section "Device" Identifier "Videocard0" Driver "nv" VendorName "Videocard vendor" BoardName "NVIDIA GeForce FX (generic)" VideoRam 131072 EndSection Check out this thread for more info: http://www.linuxquestions.org/questi...threadid=92073 |
Thanks all.
every thing is working fine. after i changed the video card settings, my monitor when nuts, saying the refresh rates are out of range, so i went to the website abd got the correct settings. it was: HF: 30.0 - 70.0 VF: 50.0 - 150.0 Now every thing is working groovy. So once again thank you. |
Bill Hicks,
now that you have the config set correctly go to http://www.nvidia.com and get the latest Linux nvidia drivers. This give a little better perfomance... You willl have to install them with the X server not running so you may want to reboot into init level 3 for this. Also check out the docs for the drivers because there are some X server modules that you will want to comment out in the config file and you will also want to change Driver "nv" to Driver "nvidia" If you are going to keep this machine going for an extended period then you will be happy with the results... |
Just an FYI:
When monkeying with your XF86Config file, ALWAYS, ALWAYS, ALWAYS check that you have the right settings for the horizontal and vertical refresh rates of your model of monitor. If you have an older monitor and you put the wrong settings in, you can destroy your monitor. It can literally smoke and burst into flames (seriously). So don't just randomly stick any old number in there. |
@Capt_Caveman
Code:
VertRefresh 48.0 - 90.0 <-----Change To This For detailed explanation see this post :) |
Glad I could help.
