Monitor/Display
Deep Color
- The lack-of quotes around
30
is intentional and required syntax - This may cause issues with programs not expecting 30-bit color 1)
- This can cause games in Wine to not start under some circumstances 2)
- There is no known benefit to enabling this as of 2019/10/22

radeon
- Expects pre-SI GPUs 3)
- For SI, CIK, and newer GPUs, use
amdgpu
, along with enablingsi_support
andcik_support
respectively for theamdgpu
kernel module 4) - Using the
radeon
DDX driver caused StepMania to crash with any fullscreen mode on openSUSE TW - This caused a blinking black screen and GDM unable to start on Ubuntu 20.04.1
- Overall, probably shouldn't use the
radeon
DDX driver
