I've never had much luck with the KDE system config monitor tool. But one thing to notice - if only 3 resolutions such as 640,800, & 1024 are listed it may be an indicator you have only these VESA modes available. This is most likely due to not having the mfr's binary blob drivers installed, rather than using the open source variants. The open source versions (Nouveau for Nvidia) lag behind the mfr blob in terms of performance and feature support. KDE really demands having the best drivers runnning. Performance issues can be examined in a couple of areas. You can disable the Desktop Effects as well as change the rendering backend from OpenGL to XRender. XRender might be more suitable for older, really low end video cards while OpenGL is more horsepower intensive. I've used radeonhd driver before a couple of years ago, and nowadays use a Nvidia GTS 450. What I don't have experience with is the Intel graphics. However, the essential thing of getting off of VESA and into hardware accelerated via drivers might be something to look at. -Mike
