Dear Maintainer,

With version 0.8.1-2 of mangohud, GPU usage information is no longer being
reported. The following metrics are always shown as 0:
gpu_stats
gpu_temp
gpu_core_clock
gpu_mem_clock
gpu_power
gpu_load_change
vram

The only field that is reported correctly is gpu_name, which displays as NVIDIA
GeForce GTX 970/PCIe/SSE2.

Downgrading to version 0.7.2-2 resolves the issue.

Please let me know if you need any additional information to help diagnose the
issue.

Regards.

What desktop environment do you use? And does it run on Wayland or X11?

I looked at similar upstream issues and found:
https://github.com/flightlessmango/MangoHud/issues/1598
https://github.com/flightlessmango/MangoHud/issues/1591
https://github.com/flightlessmango/MangoHud/issues/1516

Some people seem to have found a workaround with disabling integrated
GPU or changing
config options gpu_list and pci_dev.

There are also these, but they were reported for 0.7.1 and 0.7.2 so
probably not related.

https://github.com/flightlessmango/MangoHud/issues/1523

You could also try the version distributed on GitHub by mangohud to
confirm that it's
an upstream bug and not a packaging one.

Hello Ilya,

TL;DR: It turned out to be an issue on my end I guess.

Before reporting, I tried many troubleshooting steps: uninstalling and
reinstalling, downgrading to 0.7.2-2, upgrading again to 0.8.1-2, resetting
the config, even reinstalling the nvidia drivers, rebooting at every step.
The result was always the same: 0.7.2-2 worked, but 0.8.1-2 did not.

After your reply, I decided to uninstall mangohud and test the pre-packaged
0.8.1 release from GitHub, which worked correctly.

Next, I removed that and built 0.8.1 from source, again, it worked.

Finally, I uninstalled my source build, reinstalled the Debian 0.8.1-2
package, and, unexpectedly, it started working as well.

At this point I'm not sure what exactly was wrong, but everything is
working now.

Thank you for taking the time to look into this and best regards!

Yea, very weird.
Still your report gave me some food for thought about what we should
do about nvidia on wayland with packaged mangohud.
