Hi.
I need help please.
Because I'd like to move to Debian, I have tried the Debian 6 Live
CD. However, because the screen refresh rate is fixed on 60hz, I
cannot proceed. I am unable to change the rate and leaving it on
that setting means I get migraine. My graphics card is a 256MB
NVIDIA 7600 PCI-Express which can handle much higher resolutions;
as can the monitor - an excellent Gericom CRT which can also handle
much higher frequencies. I've tried to find help but am lost in the
maze of topics none of which seem to relate. However, from a Google
search, this would seem to be a long standing problem and not just
with Debian. Interestingly Puppy has no problems in giving me the
needed screen and refresh options.
For Lenny (hopefully someone can confirm this method is valid for
Squeeze also), using the "gtf" command will output the HorizSync
and VertRefresh values needed for xorg to display different refresh rates.
For 75 Hz (change Hz and screen resolution values as needed, i.e. this example is for my monitor at 1280x1024 resolution), as root in terminal type:
gtf 1280 1024 75
Then add the last two lines in /etc/X11/xorg.conf
Section "Monitor"
Identifier "Configured Monitor"
HorizSync 80.17
VertRefresh 75
