Hi all. I filed a bug against opensource radeon driver: https://bugs.freedesktop.org/show_bug.cgi?id=49761 . I have to apply patch and see if it fixes my problem. But I don't know how to do it. Can anybody guide me through it (step by step) or point me to some good patching guide/wiki?
I am using Kubuntu 12.04.
Thank you in advance
