Public bug reported: This is a regression of Bug #275285. The problem was caused by 965GM not working correctly with framebuffer compression (FBC). In #275285 the solution was to disable FBC in xserver-xorg-video-intel code on 965GM by default (http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=d24010b7b3f2419beb40dc5ae1e8aeb3e04b5a93) and add UMS option to enable it if needed. Since UMS were removed from Intel drivers and replaced by KMS now there is no user configurable option for FBC anymore. And disabling FBC by default was removed too along with UMS code (http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=b9b159c49854d8d9d2207946bb583537bb0d48d6). KMS enables FBC for this chipset by default and there is no configurable setting that I could find to disable it. The best solution that I could come up with was to rebuild kernel with the attached patch.
Please suggest a better solution if you know one or incorporate this patch into kernel.
