Comment 5 for bug 1311838

Just built 3.14.1.
Same error occured.

Traced it down to the dkms module of fglrx.
in /var/lib/dkms/fglrx/13.350.1/build/
I ran the make.sh script manually. As it was 'currently' in 3.11 kernel - it did not apply the patch 'buildfix_kernel_3.14.patch' as the patch looks to see if the 'current' kernel is >= 3.14. well it isn't, it's 3.11. thus no patch, thus failed build dkms module and no unity desktop......
I booted into 3.14.1 kernel Runlevel 3.
ran the same make.sh - it worked perfectly.
Then ran sudo dkms autoinstall.
then a quick sudo reboot - and all is well. fully functioning 3.14.1 kernel WITH unity Desktop.

In summary:
Boot to required kernek - Runlevel 3 (or no desktop login)
#cd /var/lib/dkms/fglrx/13.350.1/build/
#sudo ./make.sh
#sudo dkms autoinstall
#sudo reboot

I will next try this on 3.15.0rc2
But now....
sleep.
