Solved Switching between TTY consoles breaks Intel hardware acceleration (i915kms)

The problem is solved!

Build the latest version of the drm-61-kmod from the ports

# pkg info | grep drm-61
drm-61-kmod-6.1.128.1402000_5  DRM drivers modules

It contains a correction of this problem.

And now with the driver "Modesetting" the problem is not played.

# cat /usr/local/etc/X11/xorg.conf.d/xorg.conf

Section "Device"
        Identifier  "Card0"
        Driver      "modesetting"
        BusID       "PCI:0:2:0"
EndSection

Hi. I have encountered an issue with broken hardware transcoding (VAAPI) and since I find out you have a very similar CPU as mine (both 4th gen, mine is 4590). I would like to know if you have run into this issue.

If I disconnect my monitor, and boot up the machine. My hardware transcoding failed and caused a kernel panic and my system reboots itself. However if I boot up my machine with a monitor, my hardware transcoding works flawless.

Step to reproduce:

1. Power down the machine competely (not reboot)
2. Remove any HDMI or DPI cables and no cable connected to any monitor from this machine
3. Boot up the machine
4. Try to play a video with transcoding, either ssh then run ffmpeg commands, or trying with Jellyfin

Please try new thread. You have a slightly different problem.

Anyway. I found the solution. Need a monitor connected to trigger this iGPU (cannot reproduce in Linux tho). So I bought a HDMI dummy.

What is "HDMI Dummy"?

"HDMI dummy" - a plug you plug into your HDMI interface that fools it into believing that a HDMI monitor is connected.
