Comment 25 for bug 1314787

Backup using Clonezilla (recommended).

STEP ONE: Remove proprietary AMD / ATI drivers.

STEP TWO:

What kernel are you using? Type in terminal:

uname -r

If you are not using this kernel (3.14.37) download it here as I know it
works very well:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.37-utopic/

You will need all three of the following packages (if your system is 64
bit; if 32 bit, download the corresponding i386 packages):

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.37-utopic/linux-headers-3.14.37-031437-generic_3.14.37-031437.201503261136_amd64.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.37-utopic/linux-headers-3.14.37-031437_3.14.37-031437.201503261136_all.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.37-utopic/linux-image-3.14.37-031437-generic_3.14.37-031437.201503261136_amd64.deb

KERNEL INSTALL INSTRUCTIONS (note, do this from a terminal in the folder
where the above kernel debs are stored):

INSTALL KERNELS:

sudo dpkg -i linux-headers-3.14.37-*.deb linux-image-3.14.37-*.deb

Reboot your system.

STEP THREE:

Do not use the drivers installed via the "Additional Drivers" app. Make
sure you are using these drivers for your AMD / ATI card:

http://www2.ati.com/drivers/linux/amd-catalyst-omega-14.12-linux-run-installers.zip

Here are the install instructions for the above drivers. Make sure you
are patient as the build and install procedures take a fair amount of time:

#prerequisite packages#
sudo apt-get install build-essential cdbs dh-make dkms
sudo apt-get install execstack dh-modaliases fakeroot libqtgui4

# If you are 64 bit, install these too
sudo apt-get install ia32-libs ia32-libs-multiarch:i386
sudo apt-get install lib32gcc1 libc6-i386

Correct dependency issues with:
apt-get install -f

# Create and install deb packages for trusty after unzipping the AMD
driver package:

sudo sh ./insert_amd_driver+package_name_here.run --buildpkg Ubuntu/trusty

sudo dpkg -i fglrx*.deb

# Enable new settings (make sure you do this before rebooting).
sudo aticonfig --initial -f

# Reboot your PC

Your problem should now be solved.

It is recommended you keep the install packages for both the video
drivers and the kernel. Keep the instructions as well as you will
repeat the process with new drivers etc..
