I have been having some screen freezing issues on my new Ubuntu 16.04 system, and have been in the troubleshooting process for this issue. I thought it was a graphics driver problem, as I am running an AMD R9 380x card which was supposed to be fully supported by the open-source AMDGPU driver preinstalled with 16.04, but after looking around online, many people seem to have issues with. I thought the answer would be to install the recently released AMDGPU-Pro driver here, following the instructions from here. However, when I reboot I am getting a black screen. Is there an easy way to revert my changes back? My machine was semi-functional with the freezing issue but now with no video at all is useless to me. How to proceed?

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.

This may happen if you have installed both nvidia and AMD drivers. You must also remove NVIDIA drivers and restore native ones. This helped me after following the above linuxconfig.org/… Dec 26, 2021 at 5:08
- Power off your system.
- Power on the system, at the same time press on Shift key.
- Select advanced recovery option & enter your password
Then type the command:
mount -o remount, rw /
This will give read write permission.
Run command:
amdgpu-pro-uninstall
This will uninstall amdgpu-pro from your system.
To shutdown system, run command:
poweroff
& then power on the system.
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

1Do you have a reference for the --px option? I can't find documentation on what it does.– kalenpwDec 14, 2018 at 16:54

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.

Same for me. Problem continued to occur with amdgpu-pro uninstalled, until I manually uninstalled amdgpu-dkms. Running Linux mint 19.3, kernel version 5.4.0-73. Thanks!– MuckeeMay 24, 2021 at 11:01
I suggest to never use official AMD drivers with Debian-based distros like Ubuntu.
To remove them, from a terminal, run:
sudo apt remove firmware-amd-graphics
sudo apt remove firmware-linux-nonfree
