Dear all, after having bad experiences with nouveau (using fedora 15,16,17) , which resulted in an immediate lockup of my old server machine, i have given noveau another chance to run on a fedora kernel: Linux version 3.5.3-1.fc17.x86_64 (mockbuild@) The good is news is - it doesn't lead to immediate lockup of the machine anymore. The bad news. It still leads to a scrambled console screen, which does not contain any useful information. It seems that there is an "INVALID_CMD" issued by the noveau driver. Can anybody help me to resolve this problem? The hopefully useful information i have compiled in the attachements dmesg |grep nouveau >nouveau-grep.txt lspci |grep -i vga >vga-grep.txt cat /proc/version >version-grep.txt Kind Regards Dietmar
