My NVidia graphics card is not recognized some time after boot

Hi All!

I am fairly new to arch so bear with me here. I have been having a problem on my machine that after a little bit of using it, my graphics card is no longer recognized (I think). Right when I boot up the machine, everything works fine, but usually after downloading a file or just watching youtube, I won't be able to launch games or sometimes my terminal emulator anymore. I also use this machine to mine ethereum when I am not using it, and if I launch lolminer, the program I use to mine, right after a restart, everything works just fine and my GPU is detected. However, after using the machine for a while it just won't start. I have found as a temporary fix to log out and log back in to fix the problem, but I would rather not have to do that every time I want to play a game. I am currently on the latest kernel (5.15.13-arch1-1) and I am using the latest nvidia drivers (495.46-7).

These are my specs if this helps:

CPU: i9-9900KF
GPU: NVidia RTX 2070 (non super)
DE/WM: GNOME 41

Here is my lolminer output when it is working:

Setup Miner...
OpenCL driver detected.
Number of OpenCL supported GPUs: 1
Cuda driver detected.
Number of Cuda supported GPUs: 1
Device 0:
    Name:    NVIDIA GeForce RTX 2070
    Address: 1:0
    Vendor:  NVIDIA Corporation
    Drivers: Cuda
    Memory:  7979 MByte
    Active:  true (Selected Algorithm: ETHash Cuda)

Here is my lolminer output when it isn't working:

Setup Miner...
OpenCL driver detected.
Number of OpenCL supported GPUs: 0
Cuda driver detected.
Number of Cuda supported GPUs: 0

Please let me know if I need to provide any more info :)

I seem to have now found the issue! Here is a link to another forum explaining the issue.

Hope this helps if anyone has the same issue.

Re: My NVidia graphics card is not recognized some time after boot

If a logout "fixes" this,  possible an issue with a transient hostname, what's your

hostnamectl
cat /etc/hostname

Also check/post your dmesg/journal

sudo journalctl -b

when it happens for potential errors. https://wiki.archlinux.org/title/List_o … n_services

Please wrap command outputs in [ code ] [ /code ] tags without the spaces or use the link above for using pastebin sites.

Somewhat of a random shot, maybe you're losing the device file, see e.g. https://wiki.archlinux.org/title/NVIDIA … with_NVENC

Edit: Ah didn't hit refresh, looks probable.
