No actually you are right on the nose. That is the exact issue. When working with graphics (particularly in games) it is often necessary to change the monitor refresh rate, This is needed both for testing and for playing some games. I have found that some 3D linux games will not run unless I reset /etc/X11/XF86Config. This is a common thing with 3D graphics in general.

Hmmm, I have never had a game in Linux not play because of the refresh rate I had selected. In fact I can't remember a game in Windows not playing because of the refresh rate. I still fail to see how that has anything to do with games or 3d graphics. You sure you aren't referring to frame rates (FPS)? If so, that is a totally different issue which would be related to depth and resolution. I'm still confused.

I have had several people wonder why I messed with their settings. Not a one of them had bloody eyeballs when they thanked me the next day.

No I am not refering to FPS (Frames per Second). An FPS of 34 or greater will offer a smooth gaming play. 34 may be a bit slow but it will be smooth.

I am referring to a combination of 2 things that cause this problem.

1. Hardware incompatibility. All monitors don't work perfectly with all video cards. For that reason 3D can be problematic.

2. Graphic rendering engines. Certain engines do a very poor job of compensating for the compatibility issues mentioned in 1 above. A perfect example of that is Diablo II's 3D rendering engine. It offers great 2D but its 3D can be very bad depending on what video card and monitor combination you happen to use.

I theory DirectX and OpenGL should compensate for this problem but it does not always do so.

If you check the doc's of many games they will suggest that if you have problems change your refresh rate to default. In most cases that does fix the problem too. However as you pointed out once you get out of the game you want to easily change it back because defaults do cause flicker during normal (non-3D) operations.

That is why I would like to see the option to quickly and easily change your refresh rate with in X and the active desktop and not be required to restart X or reload the desktop.
It would also be nice to be able to switch desktops without having to log out. IE I am runnning KDE but I want to do X in Gnome because I find it easier. Instead of logging out and relogging in under Gnome it would be very nice to be able to click a button and instantly switch to Gnome. Then when I am done return to KDE with another click.

Wha? VGA is VGA... it's a simple analog signal. Only cheap-ass screens should give you fits, as they won't handle high refresh rates.

As for "hardware incompatibility" that only comes into play when you start talking about these newfangled digital display interfaces like DVI and ADC.

Centurian:
You are right VGA is VGA but your forgetting that VGA is limited to 256 colors. What we use today is a combination of VESA and SuperVga. Yes they are all still called VGA and they are all VGA compatible (that is why windows defaults is a 16 color VGA display) but todays monitors are a lot more than just simple VGA. They are very advanced and there are incompatibilities between monitors and Video Cards. Yours may or may not be 100% compatible. I have several comps here 1 is 100% compatible. The others are mostly compatible.

That is the reason why game companies always recommend using the default refresh rate should you have problems.
