Hmmm - how do i concigure my LCD

[Diss]

Hi
I have Ubynutu/Dapper and have just changed from a CRT to a LCD (Viewsonic VX922).

One initial worry is that the preferences/screen resolution says its running at 75hz when i think it should be 60 - it says "WARNING: Do not set the graphics card in your computer to exceed a resolution of 1280 x 1024@75Hz or the maximum refresh rate of 85Hz at lower resolutions; doing so may result in
permanent damage to your LCD display."

So i seem to be just OK but if i lower the resoltion my freq will be too high and i only have the one option in the dropdwon of 75.

Moving on my very limitied knowledege thinks i may need to reconfiger the x-server? I tried that (though now can't recall where i got the command to do it" but it totally messed things up and i had to copy back my old xorg.conf file to restore things. The reason it messed up was that i did not understand a lot of what it was askng me to input.

I thought maybe i could jst edit xorg.conf manually but there doesn't seem to be anything in it that defines frequency.

Any suggestions?

Many thanks

run 'sudo dpkg-reconfigure xserver-xorg'.

this was generated using the gtf script this is correct for a 1280x1024@60Hz

you need to add something like this to your "monitor" section


# 1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync

Then in "screen" add the Modes line to Subsection Display.

Section "Screen"
Identifier "Screen0"
Device "NVIDIA GeForce 2 GTS (generic)"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024_60.00"
EndSubSection
EndSection

As always backup your config files before editing them
