flickering screen at 72 refresh rate

flickering screen at 72 refresh rate

Post by Paul » Mon, 15 Feb 1999 04:00:00



Hello,

If I want to have my resolution at a 800x600, it keeps flickering even
at a refresh rate of 72 Hrz. How can this happen. I tried all four
hsync/vsync possibilities, and -hsync +vsync gave the best result. Below
is what a X -pobeonly gives me. My Diamond Stealth 32 card isn't also
able to use the linear mode and I'm wondering what the SpeedUp code
means.

Can anybody help me? I use the Red Hat 5.2 distribution.

1. Screen refresh rate

Hello.  I'm a relatively new user of Linux.  I'm running Redhat 4.2 w/
fvwm95 and have a Diamond Stealth 3D 2000 video card w/ 2MB of memory
and a NEC A700 17-inch monitor.  I want to run X windows at 1024x768
resolution at 16bpp w/ a vertical refresh rate of 85 Hz.  What files
(I'm thinking the XF86Config file), if any, can I change so that I can
do this?  Thanks ahead of time.
