The most interesting part is probably:
Code:
Section "Monitor"
    Identifier     "VX2025wm"
    HorizSync      60.0 - 77.0
    VertRefresh    60.0 - 75.0
    Option         "DPMS"
EndSection
I copied this from one vx2025wm user except it was then
HorizSync 60-70
VertRefresh 60-70

but also my modified version works.

My problem is that monitor shows
H.Frequency 65 kHz
V.Frequency 59,7 Hz
And I would really like to see 75 Hz or as close to that as possible.
I tried to use
HorizSync 30.0 - 82.0
VertRefresh 50.0 - 75.0
but that resulted in "out of range"

Is it because linux likes to stick to the lower fps limits?
How can I get 75Hz out of my monitor?

Thanks in advance!

You can't get 75 Hz out of your monitor. It is an LCD. Linux doesn't "like" to stick to lower fps. It is a physical limit of your monitor.

stress_junkie is right, but in my opinion for the wrong reason. If you read the spec, it states
Quote:
COMPATIBILITY
PC
VGA up to 1680 x 1050 non-interlaced (max. 60Hz)

Mac®¹
Power Mac™ G3/G4/G5 up to 1680 x 1050 non-interlaced (max. 60Hz)
Your preferred resolution is 1680x1050 and that can only be achieved at 60 Hz. If you want a higher refresh rate, you need to lower the resolution.

So why did you change it?

Is that on the same hardware? Or a different computer at all? You might be able to compare the two config files (sections device, monitor and screen).

74mhz is very low value for anything that relates to video, either vertrefresh (roughly 1 refresh every 14 seconds) or horizsync (it takes 14 seconds to write one line on the screen)

Or it is 74Mhz which is a completely different animal and might make more sense.


Please post:
- your hardware config (specifically video card and monitor)
- the above mentioned sections of the X configuration file

And the same sections in your mepis box? And what is the monitor?

PS a lowercase m stands for milli and an uppercase for Mega. So is there really an M/m in the shown refresh rate? And if so, which one?

There are slight differences in the modelines. Although I'm not sure it it will solve it, I would remove all modelines from the sabayon xorg and see if that works.
If not, copy the necessary modelines (i.e. only 1024x768 ones) from the mepis box config to the (modified above) sabayon box config.

If that does not work, I'm lost.
