I had the same problem and managed to fix it: 1. sudo gedit /usr/src/fglrx-8.771/2.6.x/kcl_ioctl.c
Navigate to the end of this file. Change the line causing the problem from: return compat_alloc_user_space(size); to: return arch_compat_alloc_user_space(size); 2. Run a terminal cd /usr/src/fglrx-8.771/ sudo ./make.sh 3. Complete the fglrx installation that had failed: sudo dpkg --configure fglrx 4. Install the remaining packages of fglrx 8.771 cd /var/cache/apt/archives/ dpkg -i fglrx-modaliases_2%3a8.771-0ubuntu0sarvatt~lucid_amd64.deb dpkg -i fglrx-dev_2%3a8.771-0ubuntu0sarvatt~lucid_amd64.deb dpkg -i fglrx-amdcccle_2%3a8.771-0ubuntu0sarvatt~lucid_amd64.deb 5.
