The wife's desktop is running KDE 4.3 on a fairly decent homebuilt machine: 2 gHz dual-core processor, 2 GB RAM, ATI graphics: $ lspci | grep ati 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200 Graphics The composting effects are terribly slow, and many effects (Wobby Windows, Cover Switch) refuse to start. I have tried googling KDE4 composting problems, but all I find are complaints and no solutions. Where can I start troubleshooting? The distro is Kubuntu 9.04, same as I run on my daily driver laptop with inferior hardware and no problems. Thanks in advance for any ideas. -- Dotan Cohen http://what-is-what.com http://gibberish.co.il ___________________________________________________ This message is from the kde mailing list.
