I got an update today to Linux 5.13 and nvidia 470 (formerly 465) and that seemed to have broken my dGPU. I am on a HP Spectre x360 15" and have been running a GTX 1650 Max-Q alongside an intel 9750H for a year without problems on this machine. Hybrid GPU worked perfectly, just had to start the nvidia dGPU with extra environment commands for some apps.
After the driver update it purely runs on the intel GPU and kernel messages give me:
kernel: NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x26:0x56:1257) kernel: NVRM: GPU 0000:01:00.0: rm_init_adapter failed, device minor number 0
I am dual booting win10 and checked if the GPU got broken, but in win10 it is working flawlessly. So its no hardware issue.
As grub boot params I have only set a resume UUID for hibernation on the laptop, nothing more, so its a clean launch. I tried with Linux 5.13, 5.12 and 5.10 on all the same error occurs.
I always left the driver to be installed by Manjaro Linux MHWD Manager and never attempeted something manually.
Do you have an idea what could be wrong? I tried downgrading to nvidia-utils 465.31 but it warns me that the actual version of nvidia-utils is a dependancy of linux513-nvidia (respectively 512 and 510) so I didnt continue on that path.
What am I doing wrong? Thanks for your help in advance.
