Comment 5 for bug 1635906

Hi! At last I... SOLVED!!!

Before I saw:

http://askubuntu.com/questions/436374/how-to-get-rid-of-the-gallium-0-4-on-llvmpipe-llvm-0x300-driver-intel-needed

...then I saw:

https://wiki.ubuntu.com/Kernel/LTSEnablementStack

...later, on a terminal, I've run:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial

...and, after a restart, my PC returned to work with the correct "Intel® Sandybridge Desktop" instead of "Gallium 0.4 on llvmpipe..."!

I hope that it can help you.
