it's good to hear that Gnome (e.g.) is running fast. So it's possible. But we made a decision to use KDE in 2000! At this time, KDE was the most complete window manager and this was an important reason to migrate common users to a Linux desktop. Since then we have a userbase of 40-60 colleagues (scientists, technicians, administration) using a KDE-Linuxdesktop on thin clients. Around the middle of the 90s we switched to LTSP. It is no option to switch from KDE to Gnome, xfce or any other window manager only because a problem occurs. We have to solve it. Most of our users only want to manage their daily work efficiently. They don't have lots of computer skills. Rolling out a new window manager means a lot of work and likely yields new/other problems. > If you think that graphics in general are slower, and it's not a > window-manager/compositing issue, then try x11perf, gtkperf or something > similar to compare the results with the older installation. How can I know if it is an "window-manager/compositing issue"? The KDE window manager kwin uses either OpenGL or XRender. I found no significant differences between those. In my opinion this must be handled automatically. When I sometimes work with my same account on AMD-, Intel-, or VIA-based clients I (the users) don't want to always change some rather internal options like the composite type. I only can imagine some generic options either on the server or on the client side about things like compression, encryption, or general thin client options. I really would appreciate some hints, how to systematically get closer to the problem.
