Nick's PPA did sovled my low-graphic problem on a HP laptop (I7/6770M) for ubuntu 12.10/amd64

However there are 2 steps must to be taken, or-else still low-graphic( segmentation fault shown in Xorg.0.log):

1. run "sudo dpkg-reconfigure Xorg" before reboot

2. when linux kernel is 3.7 or higher, another patch must be apply to Nick's fglrx-updates_9.010-0ubuntu1~andrik7_amd64.deb
for deb file usr/src/fglrx-updates-9.010/firegl_public.c, add follow 4 lines to the head of file

// VM_RESERVED is deleted in 3.7 or higher kernels.
#ifndef VM_RESERVED
#define VM_RESERVED (VM_DONTEXPAND | VM_DONTDUMP)
#endif

then rebuild the deb and install it, which would resolved the error msg
