Kernal 6 can't find 940MX anymore

Hello,

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

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
00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v6/7th Gen Core Processor Host Bridge/DRAM Registers (rev 02)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)

00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21)

00:1d.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #9 (rev f1)
00:1f.0 ISA bridge: Intel Corporation Sunrise Point-LP LPC Controller (rev 21)
00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21)
00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)
00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21)
3b:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

3d:00.0 Non-Volatile memory controller: Toshiba Corporation XG4 NVMe SSD Controller (rev 01)

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

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?
