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:
it states permission denide.
If any one knows how to fix this reply.
If any one how has a GeForce FX 5200. tell me what settings you used at installation.
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.
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:
Now below that section, there will be one titled Screen. Make sure it lists your video card and that for Monitor, it points to the Monitor section that you just edited before. For the Modes entry, put in a low resolution to start out. It should look similar to this:
Device "RIVA TNT2" <----This will be your videocard
Monitor "Monitor0" <----This should point to your monitor section
Modes "800x600" "640x480"
Now go to the top of the file and look for the section titled Server Layout . It will look like this:
Screen 0 "Screen0" 0 0 <---make sure this points to the Screen section you just edited
InputDevice "Mouse0" "CorePointer"
InputDevice "Mouse1" "SendCoreEvents"
InputDevice "Keyboard0" "CoreKeyboard"
Don't worry about anything but the line that says Screen. Make sure that the Screen entry says Screen0
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.
The Monitor subsection will be towards the bottom of the XF86Config file. You can use a text editor to make the changes to the file, remember to save the file and that you'll have to be root to save any changes you have made.
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.
