Ubuntu 21.04, Nvidia driver 470
1. Shutdown
2. Booted into UEFI: Configured Intel APU as primary graphics controller. Saved. Rebooted.
3. Removed HDMI cable from Nvidia card and plugged it into the mainboard
4. Booted into KDE, started Nightly, noticed it's still using Nvidia.
5. Nvidia X Server settings said PRIME offload is active. Selected "Intel (Power Saving Mode)", saved. It wanted a reboot. Rebooted.
6. Started Nightly and found out it's not qualified for hardware WebRender. GLX/EGL do not matter.

I remembered bug 1640053 comment 7 as a possible solution, but it does not seem to be correct (anymore?): My Intel laptop, for example, does not have EGL_EXT_output_drm.
