mining hardware – miner v3.0 wont mine with my nvidia geforce 940MX graphics card

so, I recently got into mining bitcoin and I’m trying to use my laptop to mine some (even though it wont be much :/ ).

The problem I’m having is that miner v3.0 shows an error next to my graphics card and wont mine with it. I checked on the support page and found that the graphics card must support CUDA 5.0 or higher, whiich the GeForce 940MXX does.

I am confused as to why it wont work. Any help is appreciated.

nvidia – Ubuntu 20.04.2 LTS won’t wake up after extended AFK periods

For the past few days, every morning I come in I have to reboot my workstation. Previously, I had disabled suspend on it (I don’t recall how) and the issue went away, but a few days ago I installed some updates and it started this behavior again.

Symptoms:

  • Workstation is on
  • Screen is off
  • I can ssh into it
  • I can’t turn the screen on
  • I can cycle between systemctl isolate multi-user.target and systemctl isolate graphical.target to get the screen to turn on, but mouse and keyboard still don’t respond.
  • I can only reboot to be able to use it and it takes a long time to reboot

HW Info:

  • Dell Precision 5820
  • Intel(R) Xeon(R) W-2295 CPU @ 3.00GHz
  • nVidia Quadro P2200 (Driver: nvidia-driver-460.39-0ubuntu0.20.04.1)

virtual machine – Installing NVIDIA GPU drivers on Azure N-Series VM

I provisioned an NV8as_v4 virtual machine in my Azure subscription. The application I plan on running requires OpenGL 2.0 or greater support so I’m looking at Azure’s N-series VMs for their GPU support. However, I’m running into issues getting NVIDIA drivers installed on this machine. Here is what I’ve tried and the result of each so far:

  • Provisioned the VM and attempted to install drivers manually according to instructions here: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/n-series-driver-setup. Running the executable driver file indicates that no supported video card was found. See Screenshot #1.
  • Provisioned the VM and attempted to install the NVIDIA GPU Driver Extension via the Azure portal (VM > Extensions > Add). The result of the extension installation was Provisioning Failed and the server ended up in an infinite reboot cycle (I could log in if I did it quickly enough, but received a warning that a reboot was imminent with a reboot initiated within seconds). I was able to pull up Device Manager before the reboot. No NVIDIA drivers detected (see Screenshot #2).
  • Deleted the prior VM and provisioned another, this time installing the NVIDIA GPU Driver Extension as part of the VM provisioning (using the Advanced tab on VM setup). The result of the extension installation was Provisioning Succeeded but I experienced the same reboot behavior as above and Device Manager did not detect the NVIDIA drivers (See Screenshot #2).

I have to be missing something simple as this seems like basic functionality for an N-Series VM. Any thoughts on how I can get this N-Series VM to install the proper drivers?

SCREENSHOT #1

VM can't locate compatible hardware

SCREENSHOT #2

Device manager doesn't show NVIDIA drivers installed

Nvidia drivers on ubuntu 20.04 isn’t working!

I have a running ubuntu 20.04 system on my laptop with an intel i5 4200m processor and intel had graphics. So I switched my SSD on which the os was installed and installed it to my desktop pc which has a GT710 ( Nvidia ) graphics card on it. I also had a ubuntu 20.04 lts installed on it. For some personal reasons, I switched the hard drives. Everything was running okay but when I switched the Nvidia-460 driver from additional driver options on software & updates my display stopped working on next reboot. I tried with 450 too but it’s not working. And the default open-source driver for the graphics card on ubuntu is not that eye-catching to me.

But I have ran the 450 driver on my previous ubuntu installation but on this it’s not working. Is there any way to install the nvidia drivers on my ubuntu 20.04 LTS or any type of driver which is tested to run smoothly on Nvidia GT710 ?

Thanks is advance

Ubuntu 20.04 – Run monitors only IGFX and OC Nvidia GPU without offloading

I would like to run my two monitors in the Intel HD card and run the mining software in the GPU, with OC.

However Ubuntu 20.04 offload the video to the Nvidia card by default, when running the mining software my display freezes from time to time due to the load.

I can successfully avoid this by following some instructions to run the kernel with nogpumanager and adding just the intel driver in xorg.conf

That works great EXCEPT that I can’t OC the card any more, as PowerMizer becomes unusable.

Any tips on how to configure this setup? thank you

nvidia – Battery life way shorter in Ubuntu than Windows

I have a Samsung Expert X50 NP350XBE-XH3BR with an Intel Core i7-8565U, iGPU Intel UHD Graphics 620 and a dGPU Nvidia GeForce MX110. My machine comes originally with Windows 10, but I switched to Ubuntu 20.04. In Windows, I can achieve about 6h of battery life, but under Linux it’s dramatically reduced to 1h.

I’ve installed TLP and ran with these configurations:

CPU_SCALING_GOVERNOR_ON_BAT="powersave"
CPU_ENERGY_PERF_POLICY_ON_BAT="power"
SATA_LINKPWR_ON_BAT="medium_power max_performance"
INTEL_GPU_MAX_FREQ_ON_BAT="600"
INTEL_GPU_BOOST_FREQ_ON_BAT="700"
# Because I have NVIDIA GPU:
RUNTIME_PM_DRIVER_BLACKLIST="mei_me"

It seems that TLP is acting, as now my battery lasts 2h long. However, it’s still way shorter than Windows.

I’ve also tried to use auto-cpufreq, and now I can achieve 3 hours of power doing simple tasks.

I can disable NVIDIA’s GPU using nvidia-settings, but I don’t know if it would mean just throwing my dGPU in the trash and never using it.

Could anyone help me with this optimization?

Nvidia driver problems on 20.04

The following does not work: https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-20-04-focal-fossa-linux

It also has no mention of testing the result works.

This is my test:

$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I have done this many times in the past and am referring to my old notes but nothing is working.

I am purging nvidia nad cuda in between.

I am running purely on command line so I only care about the minimal command line instructions.

Am wondering if something has changed with the paths in 20.04. There is this weird file

cat /usr/lib/nvidia/alternate-install-available
The NVIDIA driver provided by Ubuntu can be installed by launching the "Software & Updates" application, and by selecting the NVIDIA driver from the "Additional Drivers" tab.

And I should mention I am running in headless mode (no monitor attached) so if there are any weird triggers that the monitor usage happens to trigger that would be useful to know. This did not use to be the case as I have installed on servers in the past.

And I have a GeForce RTX 2070 … maybe that is the issue. Not sure yet.

virt manager – We give the bird to Nvidia, fine, but lets look in the mirror too

#1
Why does Virt-Manager need a new VM to be started then stopped in order for the MODEL: ______ selection GUI dropdown to appear under CPUs?

#2
Then, under the above GUI, once you find MODEL:_____ selector why isn’t “host-passthrough” a selectable entry?

#3
We need to type “host-passthrough” into a dropdown menu? This is not intuitive.

These three are examples of how we make it hard on ourselves to make PCI passthough more available to the average joe. And joe, I know you are struggling with passthrough, hope this helps you solve something in your journey.
