[kde-linux] KDE 4.2.4

[Louis Hinman]

I unchecked "Enable desktop effects", which makes a big difference.  Thanks sc.

Can't tell where to go removed the system tray.

Best Regards,

two things come to mind immediately

1) turn off compositing -- those desktop effects are expensive 
from a resource point of view

    Personal Settings --> Look & Feel --> Desktop
    uncheck Enable desktop effects

2) make sure you do not have the SysTray widget on your panel -- 
some people tweak it til it's not hogging your cpu, i recommend 
avoiding it altogether -- it's tough getting used to not having 
it, but it's buggy and can eat your box alive -- you can use 
'top' in a konsole to see plasma-desktop using 75-80% cpu before 
you get rid of this cycle stealer

hth,
