[Newbie]Please help: refresh rate too high in RH8 generated config.
Hi, I've installed RedHat 8 on my machine and am running into a bit of a problem with the xserver. I'm trying to run my monitor, a Viewsonic G810, at 1600x1200 but something (xserver ??) keeps insisting on using a refresh rate of 85.2 Hz, higher than that which my monitor supports at that resolution. Here are some details: >From Viewsonic's site, g810 characteristics: Horizontal refresh range: 30 - 97 kHz, Vertical refresh range: 50 - 180 Hz What I've tried: First, I used the Redhat setup configuration. When I restarted after install, I got the black screen of death. Then I ran /etc/X11/bin/xf86config manually and set the ranges above, restarted the xserver, and again black screen of death. Then I hand edited the config file, entered explicit values (as opposed to ranges) for Hor/Ver refresh rate of 94.848/76 (calculated from http://zaph.com/Modeline/), restarted the xserver, and black screen you get the idea. I know that the monitor will do 1600x1200 @ 76Hz, but for the life of me, I cannot find where (actually how) to explicitly set vertical refresh. I believe the rate based on the numbers entered in the file at /etc/X11/XF86config for horizontal and vertical ranges based on which mode you select. Unfortunately, it always tries to set 85.2 Hz which the monitor won't support. For some reason, it seems that the xserver is ignoring the values that I am using in the XF86config file. Oddly, I've changed the settings in the XF86config file to the explicit values of 94.848 kHz and 76 Hz, restarted the xserver, and it doesn't affect the rate that xserver attempts to set. Can anyone here help me with this? Thanks, --LB p.s. (As a side note, the above url says to put this in the XF86Config file.

When I Does this mean that you ran the redhat-config-xfree86 tool from the commandline as root? That tool enables you to enter the ranges and to select the resolution and it will calculate the max acceptable modelines. > restarted after install, I got the black screen of death.

I believe the rate based on the numbers entered in the file at IIRC, there are a set of preset VESA modes built-in to the XFree86. If your desired modes are in anyway determined to be incorrect then they will be used to override the XF86Config [snip] What does "ddcprobe" return?

Re: [Newbie]Please help: refresh rate too high in RH8 generated config.
I don't know RH 8 but RH 7.x generates two config files both located in /etc/X11. The one XF86Config is there for those who use X 3.3.6 the other XF86Config-4 for those who use X 4.x.x If you have such a setup, any change to the wrong config file won't have much effect...

Re: [Newbie]Please help: refresh rate too high in RH8 generated config.
Unless I'm mistaken, you should be editing the XF86Config-4 file.
