I recently installed Ubuntu 12.10 on my new Lenovo G780. I followed these instructions to install the drivers for my graphics card. When I reboot I can log in, but nothing happens after. I switched to a virtual terminal and ran dmesg. I got this:

[ 202.106458] compiz[2028]: segfault at 30 ip 00007fb16b0b7576 sp 00007ffffa1d27f0 error 4 in libgrid.so[7fb16b0a5000+27000]

This was the error I got when I installed the drivers:

DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/dell_latitude

DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/put_your_quirs

I let the system do a bug report, but I was wondering if anybody has found a fix. Thanks for your time. If there's any other information about the computer you need, let me know.
