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

16.04amd-graphicsdriversfreezegraphics

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?

Best Answer

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.

You might try running the installer NOT as root.

So don't sudo -i or anything.

Don't sudo ./amdgpu-pro-install either.

Just run as unpriviliged user who can use the sudo command. The script will call sudo for you, but if you are already root it won't be able to "drop" privileges later. Buggy because it assumes a umask when it should define one specifically.

It tells you what to do if you read the next few sentences:

The script will use the package manager to install the components of the graphics stack, with a short delay during the DKMS (Dynamic Kernel Module Support) installation. From the directory where you extracted the archive, issue the following command:
amdgpu-pro-driver/amdgpu-pro-install

But it turns out these instructions are more than a little misleading and confusing.

Instead of following them, follow these:

Download the driver. At the time of this answer, the filename is amdgpu-pro-16.40-348864.tar.xz, but this will change.
Extract the driver.
- Enter the directory where you downloaded the driver file (default is ~/Downloads). Use cd dirname, where dirname is the name of the directory.
- Use the command tar -Jxvf filename to extract the driver in the current directory. filename is the name of the name of the driver file downloaded.
Install the driver.
- In the same directory, run cd foldername. foldername is the name of the folder that was created when the driver file was extracted. It should begin with amdgpu, so type cd amdgpu and then press Tab so that it completes the folder name
Reboot.
- Once the terminal returns to a prompt, restart the computer. AMDGPU-PRO will now be installed.
