Disable Green artificials

[draganvictor14 (Victor Dragan)]

I have an Asus FA617NS and I don’t want to have green artificials
Is there a way to disable on Fedora?

Thanks!

My goodness AMD has some fun flags hidden behind random numbers

This should do it:

sudo grubby --update-kernel='ALL' --args='amdgpu.dcdebugmask=0x200'

Or manually:

sudo -e '/etc/default/grub' && sudo grub2-mkconfig -o '/boot/grub2/grub.cfg'

GRUB_CMDLINE_LINUX="rhgb quiet amdgpu.dcdebugmask=0x200"

If amdgpu.dcdebugmask=0x200 doesn’t improve the situation, try amdgpu.dcdebugmask=0x10 instead.

@litemotiv

amdgpu.dcdebugmask=0x200

And for amdgpu.dcdebugmask=0x10

I want to use both!

Then the combination would either be amdgpu.dcdebugmask=0x300 or amdgpu.dcdebugmask=0x210 depending how the values associate… I’m guessing the latter (0x210), or they wouldn’t bother specifying the trailing zeroes at all.

(But it’s needlessly confusing that they write amdgpu.dcdebugmask=0x10 for the smaller value, instead of amdgpu.dcdebugmask=0x010 which would eliminate any possible confusion.)

It’s currently working but it still appears sometimes. Is it possible to disable it permanently?
