====== Ubuntu - GPU - AMD GPU - Troubleshooting - Crashes the System ======

It seems GPU drivers from AMD are not great; and may crash the system.

Add the following to the **/etc/environment** file.

<file bash /etc/environment>
# Disable all hardware acceleration in Firefox, since OpenGL is causing crashing on Navi, WebGL is the culprit.
#AMD_DEBUG="nongg,nodma"
AMD_DEBUG="nongg nodma"
#AMD_DEBUG=nodma
#AMD_DEBUG="nongg"
#AMD_DEBUG=zerovram
</file>

<WRAP info>
**NOTE:**  Some sites say to use various variations of the above, but the uncommitted entry works for me.
</WRAP>

Add **amdgpu.noretry=0** to the **GRUB_CMDLINE_LINUX_DEFAULT** option:

<file bash /etc/default/grub>
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.noretry=0"
</file>

Then run:

<code bash>
sudo update-grub
</code>

Then reboot.

Try:

<code bash>
sudo sh -c 'echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level'
