OpenGL all flickery-like


I'm using a Radeon Mobility 7500 with Slackware 10 (2.4.26 bare.i).
When I first installed, I was having the problem of anything using GL was slow&choppy-like. I followed the wiki to install CVS dri, drm and mesa... That made the uber-slow choppiness go away, but now I have a flickery-ness problem with certain screen savers (which I'm using as testing). Euphoria is smooth and perfect, while GLMatrix looks as though I have the refresh rate wrong (other than that, it looks pretty good).
I tried disabling dri per a good friend of mine, but that just brought back slow&choppiness.

I'd imagine this has been asked before, but after spending quite a number of hours over several days trying to find some suggestions to my specific issue, I decided I'd rather be verbally batterred a bit and get the issue solved than rely on my seemingly pathetic searching skills to find what I'm looking for. Plus I'm about 10 minutes for laying my head on my keyboard.

Could someone please offer any suggestions or advice to help point me in the right direction to resolve this issue, please?

I don't think that 3D HW acceleration for that chipset is available from the kernel-installed "radeon" driver.

You haven't said what make and model your notebook is, but according to the ATI site, drivers may be available from the manufacturer's site, or you might look at the lists on tuxmobil.org, or Linux on Laptops to get more information on how to set up this graphics chip.

Hope this helps.
