For reference, here's the "really crappy graphics driver" on my (cheap) laptop where XRender is smooth and nice and OpenGL is horribly slow: Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) However, on my netbook -- where the performance of the two acceleration methods is exactly reversed -- lspci gives EXACTLY the same output for the display controller. Whatever. I'm not complaining, I've found settings that work on each machine. But it's very weird ... :) MEF -- Mary Ellen Foster -- http://homepages.inf.ed.ac.uk/mef/ Informatik 6: Robotics and Embedded Systems, Technische Universit?t M?nchen and ICCS, School of Informatics, University of Edinburgh
