Looks like you where right about the udev rules earlier, I ran a pacman command to find all untracked files in /usr and I found /usr/lib/udev/rules.d/50-remove-nvidia.rules was there. Contents:

# Automatically generated by EnvyControl

# Remove NVIDIA USB xHCI Host Controller devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c0330", ATTR{power/control}="auto", ATTR{remove}="1"

# Remove NVIDIA USB Type-C UCSI devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c8000", ATTR{power/control}="auto", ATTR{remove}="1"

# Remove NVIDIA Audio devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x040300", ATTR{power/control}="auto", ATTR{remove}="1"

# Remove NVIDIA VGA/3D controller devices
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x03[0-9]*", ATTR{power/control}="auto", ATTR{remove}="1"

looks like EnvyControl left some extra files after uninstalling.
Personally, I think it's pretty weird that it put runtime files in /usr/lib, if they where in /etc I would have found them quickly.
The GPU is back on the bus now and I can run optimus-manager to get my extra screen. Thank you for the help troubleshooting this issue.

dkms status doesn't even list half of my DKMS modules for some reason

I don't seem to have an -F on my dkms? when I ran that it without, it didn't rebuild all the DKMS modules for some reason, just bbswitch and evdi

hmm, maybe downgrading nvidia-dkms might work? I'll try that

[–] [email protected] 1 points 6 months ago

yeah, they are a bit of a pain, but it's a new one to me for the card to just disappear completely. It's hard to do any troubleshooting when you can't even access the card.

I had a look at /etc/udev, /etc/modprobe.d and /etc/modules-load.d, and don't see anything related to nvidia. Are there any more udev or blacklist folders to look at?

It's an MSI GE72MVR 7RG, what do mean version?
and it's an integrated intel GPU.

ls: cannot access '/sys/bus/pci/devices/0000:01:00.0': No such file or directory
I also tried booting an archiso and the GPU appears there, there must be something wrong with my install.

I have an optimus laptop, and after the update to KDE6 optimus-manager stopped working. I needed a second display, and all my display outputs are on the Nvdia GPU, so I needed to switch. I tried many different X11 configs, envycontrol then more X11 configs, but I couldn't get it working right, it would only be the internal display or the external one, not both. after a few hours I gave up and tried optimus-manager again. This time I checked the error log and it was failing to load the nvidia module, I tried loading it manually but I got a "No such device" error, which is where the title of the post comes in. My GPU has disappeared from linux, it won't show up in lspci, lshw, nvidia-smi, or anything else it should. The only reference to the thing in dmesg I can find are :

[    0.216410] pci 0000:01:00.0: [10de:1ba1] type 00 class 0x030000
[    0.216419] pci 0000:01:00.0: reg 0x10: [mem 0xde000000-0xdeffffff]

[    0.216440] pci 0000:01:00.0: reg 0x24: [io  0xe000-0xe07f]
[    0.216445] pci 0000:01:00.0: reg 0x30: [mem 0xdf000000-0xdf07ffff pref]
[    0.216460] pci 0000:01:00.0: Enabling HDA controller
[    0.257300] pci 0000:01:00.0: vgaarb: bridge control possible

[    0.270521] pci 0000:01:00.1: D0 power state depends on 0000:01:00.0

and then nothing, it doesn't even seem to try to load the nvidia module. I tried booting into windows and it shows up there fine, so the GPU didn't randomly die.
As far as I can tell I've rolled back everything I did in my histfile until it stopped working, The only thing I could think is I upgraded my kernel to (6.7.9) from (6.6.10), could that have caused it? I also tried adding pcie_port_pm=off to the kernel params from the archwiki, but still nothing. I'm just at a loss here, anyone have any ideas?

EDIT: I'm using the nvidia-dkms package
EDIT2: one kernel downgrade later and it's still not appearing, so thats not it.
EDIT3: fixed, see comments

(old) corsair CX750M PSU safety (sopuli.xyz)
submitted 7 months ago* (last edited 7 months ago) by [email protected] to c/[email protected]

I needed a PC to test a PCIe card recently, so I put something together with some spare parts. The only PSU I had around was a corsair CX750M I took from a prebuild from about 2014-2015, one with the green labels. Searching around the internet I see loads of people saying not to buy them, but what about one I already have? How bad really it is? Will it fry my motherboard or burn my house down? Or is it just inefficient?

Looking to buy some Mellanox ConnectX-3 cards (sopuli.xyz)
 

I was found a listing on eBay for a "Mellanox CX354A ConnectX-3 FDR Infiniband 40GbE QSFP+" card for quite cheap. By the sound of the listing title it supports both infiniband and 40GbE, is that right? I would like to try out infiniband, but I would be buying for the 40GbE. And are there good drivers for modern linux distros for this card? Also, do I just buy some QSFP cables to direct attach them?

Recovering Hardware RAID array in software (sopuli.xyz)
submitted 1 year ago* (last edited 1 year ago) by [email protected] to c/[email protected]

I have 3 old SCSI HDDs that were in a hardware RAID, I don't have the RAID controller anymore but I have imaged them with DD and a SCSI PCI card I have.
Is there any way to assemble this array in software on Linux? I just want to get the data off so read only is fine.
Running blkid on the drive shows it as an Adaptec RAID member.
I believe the drives are in RAID 5.

EDIT: I got it working, but I had to use windows. I installed ReclaiMe Free RAID Recovery to find the RAID parameters then used the UFS explorer Pro free trial to image the array to a virtual disk. After a quick (actual quite long) chkdsk I managed to mount the NTFS file system on the array

EDIT2: There seem to be a lot of missing files, I don't think there was anything important on here anyway

EDIT3: wow, the found.000 folder is huge. I guess the recovery failed, or the array got pretty badly corrupted on the ~10 years in storage.
