problem slackware-current kde 4.2
 

hello i am a newbie
i just install slackware from current. at first i use the desktop effects but when i use it everything seems kind of sluggish then turn off the desktop effect everything seems normal. my question is, is there any problem with the built in effects? i have used another distros like ubuntu, with its effects turn on, everything is allright.
and another problem, when i try to open the network configuration in system setting i can't open it. it said cant parse xml file(), sorry for my bad english hope someone can help me

1) You shouldn't really run current until you are familiar with Slackware. Slackware does things slightly differently, Use 12.2 preferably.
2) Slackware builds KDE 4 'as is', without all the patches the other distros apply to make it actually usable.
3) You probably don't have hardware acceleration enabled on your graphics card. What is the output of
4) KDE Network Manager is useless and has been useless for years. Use wicd, if you want something graphical, and only wicd, as it can conflict with the Slackware networks management scripts. It actually works quite well.

Happy Slacking!
