help for compiz needed [solved]

[hawklord]

hi,

 

i am running mdv2009 one from a fresh install of a 'live' cd, problem is my compiz is not working,

 

i have tried all the configurations i know but as soon as i go to system settings > desktop-system settings > configure desktop effects > general and tick the box,

log-out and log-in, i am presented with a white screen then a dark gray screen - with no desktop,

 

the only way i can get out of this is by logging out and logging back into kde3, unticking the above box, logging out and logging back into kde4 (with no compiz in kde3 either)

 

i have tried changing the driver from the default ATI one, but my system becomes unusable and i have to use knoppix to re-edit my xorg.conf

 

i have also tried control center > hardware > configure 3D desktop effects > advanced settings and choosing xgl

with this i get compiz, but its very slow and 'jerky', infact everything is slow and i have to change back to native support

 

any help or pointers would ease my headache

 

i have 1gb ddr400 ram, p4 3.4 cpu and a radeon 9550 256ddr graphics card

 

thanks

after more headaches and configurations, i have finally solved the problem

 

believing that mandriva was not the problem, left me with one other option

 

i changed my graphics card for a radeon 9250, enabled compiz and it works,

configured compiz how i want it - changed back to the 9550, white screen only,

 

changed back to the 9250 - full compiz,

 

tried the 9550 in a pclinuxos box fully configured - white screen only

 

my conclusion is that i have a faulty radeon 9550 graphics card

 

this issue is solved,

 

thanks
