Linux Screen Res

[ICGALN]

I'm new to linux (red hat 7.2) I only installed it to have a jk2 server run on it which works fine. The only problem is i want to transfer it from downstairs into my loft with a diff monitor from what i first had it on, but the monitor is old and naff and wont do more than 640*480 so i need to change my screens res only i have searched some FAQ's and documentation and it dont tell how to do that, i realise this is a place to help pll with server problems but i dont know where else to ask.

 

Any help would be apreciated.

 

Oh and i'm using KDE if thats important

Redhat should automatically pick up the different monitor. If it does not you are going to have to edit the following file by hand....

 

/etc/X11/XF86Config-4

 

You are going to need the Vertical and Horizontal refresh rates of the monitor.

 

 

In the XF86Config file look for the Monitor section. I have included a snippet from mine so you know what to look for:

 

Section "Monitor"

 

Identifier "Princeton Ultra 72"

 

# HorizSync is in kHz unless units are specified.

# HorizSync may be a comma separated list of discrete values, or a

# comma separated list of ranges of values.

# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S

# USER MANUAL FOR THE CORRECT NUMBERS.

 

HorizSync 30-70

# VertRefresh is in Hz unless units are specified.

# VertRefresh may be a comma separated list of discrete values, or a

# comma separated list of ranges of values.

# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S

# USER MANUAL FOR THE CORRECT NUMBERS.

 

VertRefresh 50-160

 

EndSection

 

Change the Horizontal and vertical refresh rates to those of your monitor. Now you are going to have to choose the default screen. Further in that same file you will see:

 

# Any number of screen sections may be present. Each describes

# the configuration of a single screen. A single specific screen section

# may be specified from the X server command line with the "-screen"

# option.

Section "Screen"

Identifier "Screen 1"

Device "Geforce 2 Ultra"

Monitor "Princeton Ultra 72"

DefaultDepth 24

 

Change the default depth to whatever you want it to be. 24 is 24 bit, 16 is 16 bit etc. Look further down in the file for the screens. You will need to make sure that 640x480 is listed first: For me I like 1024x768 so it is listed first.

 

Subsection "Display"

Depth 24

Modes "1024x768" "800x600" "640x480"

ViewPort 0 0

EndSubsection

 

If you have any further questions about the setup ask at the BBR Unix forum I post there and their are a lot of people willing to help
