Hello ;=)

I’m using AMD Radeon HD 4850 GC and radeon driver but i have a bad display : lag when starting softwares, title bars blinking, slow displays …

here are some errors i found : ///// ////// Données issues de # cat /var/log/boot.msg | grep radeon > /hom - Pastebin.com](http://pastebin.com/ziAy4HjA)

i’m using opensuse 11.4, 2.6.37.6-0.7-desktop kernel and kde 4.7.2

how can improve this ?

upgrading the kernel ? from which repository ?

Thanks :wink:
