Applications & Processes Tabs are Blank with No Items. Regression?

[robinkleem]

I know that this issue has occurred in the past and was addressed. Perhaps there has been a regression?

Here are the key facts:

• I am running the latest flatpak version of resources.
• The Applications tab shows "System Processes" 0B Memory and o.o% Processor and nothing else (see image below)
• Processes tab is entirely blank and shows nothing (see image below)
• All other tabs, including GPU, are working as expected

If I run "net.nokyan.Resources" from the cli, the application starts and works (with the issues documented above), and I get the following output:

INFO  resources::application > Resources (net.nokyan.Resources)
 INFO  resources::application > Version: 1.2.1 ()
 INFO  resources::application > Datadir: /app/share/resources
 DEBUG resources::application::imp > GtkApplication<Application>::startup
 DEBUG resources::application::imp > GtkApplication<Application>::activate

If I run "sudo net.nokyan.Resources" from the cli, the application fails to start and I get the following output:

error: app/net.nokyan.Resources/x86_64/stable not installed

I have tried toggling various settings using flatseal, but this did not make any difference.

I am happy to provide any other information that may be useful to help diagnose this issue.

Hi, thanks for reporting the issue.
Which operating system are you running?

[robinkleem]

I am running NIxOS 24.05 (Uakari) with Intel CPU and Nvidia GPU. I'm happy to provide a more detailed hardware/software breakdown if it would be helpful. Please let me know specifically what you require. Thank you.

Resources' process scanning unfortunately doesn't work as a Flatpak on NixOS since Resources needs to launch a seperate executable outside the Flatpak sandbox to do that and NixOS (as far as I know) doesn't support running ordinary executables. In #76, @Lukas-Heiligenbrunner seems to have made it work using NixOS' own package manager. Can you try that?

[robinkleem]

Firstly, apologies for not reading the previously opened issue in enough detail. As of the moment (12/12/2023), gnome-resources does not appear to be available in the NixOS unstable repo. I will try the NixOS package as soon as it becomes available in the NixOS repo. Thank you.

[Lukas-Heiligenbrunner]

Indeed it is :)

I'm wondering why everybody tries to put gnome in front of the name, although its only a gtk and not a gnome app, yet^^

Firstly, @nokyan and @Lukas-Heiligenbrunner, thank you both for your respective work on this project. I do think once the bugs are ironed-out it will be the preeminent GUI based resources monitor for Linux distributions.

@Lukas-Heiligenbrunner, apologies, resources is indeed now part of the unstable repo now. For some or other reason when I try and run it without first installing it via nix-shell i.e. nix-shell -p resources then I get an error involving error: undefined variable 'gnome-resources. However if I install the application via configuration.nix then it installs and I can indeed browse the apps and process tabs which are correctly populated.

Unfortunately however the GPU tab does not populate with the correct information.

As documented for @nokyan, if I install the flatpak version of resources (net.nokyan.Resources) then the application and process tabs do not display correctly, however the GPU tab does display correctly.

@Lukas-Heiligenbrunner, I don't want to hijack this thread to document feedback about the Nix version of resources. Is there a separate location to post feedback for the Nix version instead?

Thank you very much for your kind words. :)
Could you send a screenshot of the GPU tab? I'm not familiar with NixOS and how packaging for it works but maybe there's something I could use to locate the issue.

[robinkleem]

@nokyan, here is a screen shot of the GPU tab of resouces running under Nixos.

Here is the GPU tab from the flatpak (your official version) running Nixos.

I'm seeing the same problem, but I am running Elementary OS 6.1. That is, no processes or applications show up. I first had a flatpak installation. Then I tried installing it directly from the AppCenter. Same problem.

Can you run flatpak run net.nokyan.Resources in a terminal and send me the output?

Ran the flatpak command you asked me to run and got the following output (see attachment).

So I installed elementary OS 6.1 in a VM and could reproduce your issue.
The problem is that elementary OS 6.1 is already 2.5 years old and ships a glibc that's too old for Resources' companion process that is spawned outside the Flatpak sandbox to gather process data. Consider updating to a newer version of elementary OS.
