Here now. been dev testing visualized gpu'sLet me catch up to where you are...
You tried that boot but... You are now back to kernel 5.8 and it's associated mesa. You heard me before, and in the last couple posts, CatKiller tell you that for the newer, in-kernel graphics drivers, you would need a kerenl of 5.12 or newr, ans the newer mesa-drivers from Kisak's PAA... AND try that boot parameter...
Yes. DRM should be enabled for Vulkan and any 3D acceleration... But important for you to note that DRM is already enabled by default on the Intel i915 driver for your GPU. I remember you being confused about the term i915... That is actually "the Intel Graphics driver", written by Intel.
If you are curious, your conf file is at /etc/modprobe.d/i915.conf... It should be fine. if it has an xorg.con fi;e (which Intel usually doesn't need one... then that currnently would be at /etc/X11/xorg.conf.d/20-intel.conf...
What is more important to you is the kernel version and mesa... Mesa has the DRM which relates with your graphics driver, which is in the Kernel... So if you monitor that when you are making chnages and after your tests, then that will tell you the why's of your black screen. Such as this right after boot...
Code:
dmesg | grep -i drm
sudo journalctl -b --grep='i915'
And check those again after you test something...
One more
Code:
sudo journalctl -b ''grep='drm'
should show when the drm.service was loaded...
