I am running Suse Pro and have an Nvidia 4200 graphics card that seems to be recognized and initialized by Suse Pro. Dow anybody know how I'd go about changing the refresh rate? I'm sensitive to flicker and it's driving me nuts! Thanks!

A brief, practical add-on to the suggestions from , , and : the SUSE GUI tools they mention (YaST/SaX/xconfigurator) are fine for a quick fix, but there are two reliable approaches worth knowing now — an immediate, session-only change you can test, and a persistent X configuration change that survives reboots. Below are concise steps, sample commands, and troubleshooting pointers that work for Nvidia cards and generic X11 setups.

To test a refresh rate right away (no reboot): list current outputs and modes, then set the mode for the output. Example:

# list outputs and available modes
xrandr --query

# set a mode + refresh on an output (replace names with your output)
xrandr --output HDMI-0 --mode 1920x1080 --rate 75

# if the mode is not present, generate and add one:
cvt 1920 1080 75
xrandr --newmode "1920x1080_75.00" <modeline-from-cvt>
xrandr --addmode HDMI-0 "1920x1080_75.00"
xrandr --output HDMI-0 --mode "1920x1080_75.00"

xrandr is the standard, documented tool for this workflow. (x.org)

For a persistent, system-wide setting edit X config instead of relying on session commands. Create a small snippet in /etc/X11/xorg.conf.d (or save via nvidia-settings) that supplies Monitor HorizSync/VertRefresh, Modeline/Modes or a PreferredMode so X uses the preferred refresh at startup. The X config format and Monitor options are documented by X.Org; the Nvidia driver also exposes xorg options (ModeValidation/ExactModeTimingsDVI, UseEDID, etc.) that affect which modes are allowed. Use these with caution — forcing non‑EDID modes can break or damage hardware. (x.org)

Troubleshooting tips: check EDID and the X log to see which modes the monitor actually reports (xrandr --prop or read /sys/class/drm/*/edid and decode). If xrandr shows only 60Hz options you may be on Wayland (xrandr is X11-only) or the driver/EDID is restricting modes; Wayland compositors use their own tools. If a mode won’t stick, inspect /var/log/Xorg.0.log and try nvidia-settings (when using the proprietary driver) to write a working xorg.conf. (askubuntu.com)

Notes: pick only refresh rates the monitor supports (check the manual or EDID), and if using very old Nvidia cards confirm you have the correct driver package for your SUSE release before changing X configuration.

Try looking in Yast control centre

SaX should be able to do what you want with regards to changing all aspects of your X Configuration.

type the "xconfigurator" command on the command line

and change the sync and refresh rate of the monitor there.

it should bring up a gui for u to change it ok
