I'm running the Intel version (32 bit) of Fedora Core 6. Have been since the day it came up, and I keep it updated daily. The usual programs run fine--Firefox, OpenOffice, Evolution, etc. However, Mathematica 5.2 is VERY slow with screen opeations. Scrolling and moving windows around the screen, for example, take several seconds rather than virtually instantaneous as with other programs. You can see the "wiggling" around as the windows are being redrawn on the screen as they are moved! This happens even when Mathematica is the only program I have open. The "top" commands does not show exceesive CPU usage.

Any ideas why the GUI is so terribly slow?

Thanks.

I can't say much about locally installed Mathematica, but I'd like to say this: I run Mathematica 5.2 from time to time over SSH and it's awfully slow that way (works, yes, but I don't like moving windows around nor scrolling anything like you said too). I thought it was because I run it over SSH, but I guess that's not the case then; also the connection speed I'm running it over is 10MB (yes, megabytes) so it shouldn't bee too slow

Sidenote: I have also tried running Maple and the other big number crusher over SSH, but they were soooo slow that I never actually got more done in a day then draw up the main screen, if using X11 forwarding like with Mathematica. Text mode works great, but isn't really helpful when dealing with images. Compared to them, Mathematica is fast as lightning with X11 forwarded over SSH, but still slow enough to make me go mad occasionally.

Oh, by the way I have used Mathematica 5.2 (actually just the same installation that I run over SSH) on a FC6 pc "on site", and it ran flawlessly fast there. Really odd.
