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. I didn't do it because I'm not sure where to put it -- in the monitors section, the screen section, some other section ...)
