Black screen on boot after AMDGPU-Pro install (16.04)

Solution 1:

When your system is booted and you're at the black screen issue the following keyboard command: CTRL-ALT-F2. Login with your account. Then, run the command:

amdgpu-pro-uninstall

This should uninstall the driver and hopefully get you back working again.

Solution 2:

1. Power off your system.
2. Power on the system, at the same time press on Shift key.
3. Select advanced recovery option & enter your password

4. Then type the command:

   mount -o remount, rw /    
   

   This will give read write permission.

5. Run command:

   amdgpu-pro-uninstall    
   

   This will uninstall amdgpu-pro from your system.

6. To shutdown system, run command: poweroff & then power on the system.

Solution 3:

For me fixed by entering command line with CTRL+F1 then removing the drivers

amdgpu-pro-uninstall

and reinstall using the --px option

./amdgpu-pro-install --px

Solution 4:

Press keyboard command: CTRL-ALT-F2 and Login with your account. Then, run the command:

amdgpu-pro-uninstall
sudo apt purge amdgpu*

Even after uninstalling amdgpu pro driver I still got black screen (even i executed the command X -configure), so I go to root shell by the option in recovery mode and removed the remaining driver. I guess it was amdgpu-dkms. I infer that Nvidia user should delete nvidia driver to get rid of black screen.
