Status in linux package in Ubuntu: Confirmed Bug description: Hi to the Ubuntu team, -------------------- Key info: MSI Delta 15 A5EFK laptop dual boot Ubuntu 22.04 LTS/Windows 11 Ubuntu 5.15.0-27.28-generic 5.15.30 hybrid graphic cards: AMD RX6700M + AMD Radeon 8 Graphics Renoir (in AMD Ryzen 9 5900HX) open source amdgpu drivers -------------------- I tried to combined one bug report with one related question hoping this is fine. -The bug- I've noticed the following error when booting on my ubuntu partition: [ 0.649628] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCIO.GP17.MP2], AE_NOT_FOUND (20210730/psargs-330) [ 0.650162] ACPI Error: Aborting method \_SB.GPIO._EVT due to previous error (AE_NOT_FOUND) (20210730/psparse-529) /dev/nvme0n1p6: clean, 219896/6725632 files, 3948761/26880000 blocks I did not really worried about that first. But then when I wanted to reduce my battery draining on my ubuntu partition (half of the battery life on my windows partition for similar usage) I've seen that disabling my discrete graphic card could be one thing to try to reduce power consumption. So I thought about using (i) acpi_call as stated or (ii) vga_switcheroo as stated in https://help.ubuntu.com/community/HybridGraphics . However, for (i) I need to know the correct calls to send to ACPI and my latptop is not listed here: https://hybrid-graphics- linux.tuxfamily.org/index.php?title=ACPI_calls and obviously the call that the kernel is trying to send at boot (for whatever reason) is also wrong. For (ii) I think that vga_switcheroo is also using acpi_call under the hood to disable the discrete graphic card. Which leads now to: -Question- Can I use vga_switcheroo knowing that my kernel is sending false acpi_call? I just want to be really sure about what I'm doing here because the doc states to modifiy the grub config and I'm really not confortable with dealing with the boot manager knowing the above bug. Is there a way to find the correct ACPI call? Adittional output asked by the doc: mustang@MSI:~$ sudo grep -i switcheroo /boot/config-* /boot/config-5.15.0-25-generic:CONFIG_VGA_SWITCHEROO=y /boot/config-5.15.0-27-generic:CONFIG_VGA_SWITCHEROO=y Thank you for you help, Best regards, Jeremy --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2022-05-08 (8 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) MachineType: Micro-Star International Co., Ltd.
