Kernal 6 can't find 940MX anymore

Hello,

After an update of 'linux' package, my system is unable to see my graphic card hmm

I have 2 one with the CPU and one 940MX.

I used to use bumblebee and activate Optimus with success.

I tried the usual debug thing like 'lspci':

# lspci

I'm really lost and need help.

Re: Kernal 6 can't find 940MX anymore

I can see your Intel HD 620 iGPU in that output. It would be easier to spot if you had used code tags though tongue

I am gleefully ignorant about NVIDIA but if it isn't listed in lspci then perhaps it is broken or become disconnected. Do you "see" it if you load up a live ISO image?

Re: Kernal 6 can't find 940MX anymore

Please post the complete system journal

sudo journalctl -b | curl -F 'file=@-' 0x0.st

After an update of 'linux' package

Does it still show up w/ linux-lts?

Fyi: "kernEl", not "kernAl"

Re: Kernal 6 can't find 940MX anymore

There's no trace of any nvidia chip in that journal (10de vendor id)
Did you maybe disable it in the BIOS?
