About the 3.9 RC kernels - I will be able to test it when it hits the ArchLinux testing repository. Never compiled kernel from the source in my life and I know it would take a long time on this single core celeron CPU and it would render it useless / unusable during the process. Also my connection has a 20 gigs per month download limit and downloading kernel source from git repository would take a nice bite out of it. I hope it's ok. Installed the intel-gpu-tools as asked and downgraded kernel to the working 3.7.9-2 one and rebooted: [root@wishmacer ~]# pacman -Ss intel-gpu-tools community/intel-gpu-tools 1.3-2 Tools for development and testing of the Intel DRM driver [root@wishmacer ~]# pacman -S intel-gpu-tools resolving dependencies... looking for inter-conflicts...
