Did you manage to fix it?

[sr71684]

Can confirm I get the same result.

Did you manage to fix it?

still having the issue too

[bayasdev]

Is this a regression (it worked before with the same setup)?

[rstanuwijaya]

Is this a regression (it worked before with the same setup)?

It's my first time using envycontrol, so I cannot confirm

[bayasdev]

Could you attach the output of cat /usr/share/sddm/scripts/Xsetup after switching to Nvidia? no need to reboot so you can revert back to hybrid

[sr71684]

I get this:
sudo envycontrol -s nvidia
