I have two Intel graphics on my laptop
lspci -k | grep -EA3 'VGA|3D|Display'
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
Subsystem: Acer Incorporated [ALI] Device 1611
Kernel driver in use: i915
Kernel modules: i915

03:00.0 Display controller: Intel Corporation DG2 [Arc A370M] (rev 05)
Subsystem: Acer Incorporated [ALI] Device 1611
Kernel driver in use: i915
Kernel modules: i915When I use linux, I can't find the way how to use discrete video for better performance (like gemes). All existing tools for hybrid graphics makes for intel+nvidia or intel+amd.
Also I see some troubles in initialization process

I believe the issue was fixed at some point. With the debian sid kernel of 6.3.0-1-amd64, that still exists.
But I built a bleeding edge kernel just now. It seems the issue was fixed.
Kernel version: Linux version 6.5.0-rc3 (goodspeed@intlnuc) (gcc (Debian 12.3.0-6) 12.3.0, GNU ld (GNU Binutils for Debian) 2.40.90.20230720) #5 SMP PREEMPT_DYNAMIC Sat Jul 29 12:12:27 CST 2023
