TFT Monitor out of Freqency problem

BACTRATE · 02-02-2005, 11:10 AM

I have just installed a new TFT Monitor (GNR) and it works perfectly under
Win95 but when trying to boot into Linux it says 'out of frequency' and shuts the monitor down.So I am unable to make any adjustments in Linux.
Any help much appreciated.

which distro are you using?
can you get to a terminal? (ctrl+alt+F1~6)

Thanks Tuttle.
I am using mandrake 10.1.I will try ctrl+alt+F1 -6.

Hello again Tuttle
Can also get the command line shell by pressing ctrtl.alt f1 etc.Dont know how to configure the monitor from shell.

First, find out the horizontal and vertical refresh rate range for your monitor, then log in as root and run:

Code:

/usr/X11R6/bin/xorgconfig

This will configure the X server, asking you several questions about your hardware.
Once you get X up and running you can configure the finer details from within the KDE control centre.

There is a program you can run to estimate a modeline:
example:
/usr/X11/bin/gtf 1280 800 60 --xorgmode
will give you an xorg style modeline for "1280x800@60Hz"

This example looks like this on my system:
[jschiwal@hpamd64 jschiwal]$ /usr/X11R6/bin/gtf 1280 800 60 --xorgmode

# 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
Modeline "1280x800_60.00" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync +Vsync

I think that you may want to run this program when your computer isn't heavily loaded to get a better result.
