Thank you very much indeed; this is very helpful. I understood that glxgears was not regarded as a reliable benchmark, but the number I was getting (60FPS or thereabouts) seemed low enough that it probably indicated that something was amiss. Since then I've been trying various 3D applications to see how things stood. The results have been mixed. Some (compiz-fusion, stellarium, extremetuxracer) have no problems; others (Google Earth, foobillard) freeze the X server a few seconds after startup (not the laptop itself, though; it remains possible to ssh in from elsewhere in the home network). I hadn't known about torcs; I'll try it as soon as I can. |> I should point out that Gallium 3D support in Mesa for Radeon |> cards has been making great strides since the beginning of the |> year.

Do the developers read those forums? Something I've been unsure about it is whether or not it would make sense to file a bug-report. The only 3D applications I care about at all are compiz and Google Earth, and I can live happily without either of them. I'm exploring all of this mostly out of curiosity and a desire/willingness to help with testing, reporting etc. |> HTH, It does indeed.
