network activity graph is -blank- in Debian Bullseye Mate

[mexsudo]

new glitch: this network activity graph is -blank- in Bullseye. the text is still active...

this screenshot is from one of several Debian 10 systems, I like it. I have tried several fresh installs of Debian 11 in several machines and get the same result in all. I tried it with no packages installed but Conky, and then I did my best to duplicate the installed packages on the other Debian 10 systems. (Debian 11 aka Bullseye.. still in Testing mode).

On Debian 11, what does the system return when running the following in command line:

ls -l /sys/class/net/*

Devices seem ok, please post a screenshot from Debian 11. Also run conky from command line, and see if there are informative error messages:

conky -c /path/to/lean-conky-config/conky.conf

@mexsudo LCC has no problem identifying your network interface (enp1s0), you might want to check this with Conky developers why upspeedgraph/downspeedgraph show no activity on Debian 11.

Or try another Conky config with network activity graphs, see if you see any activities.

[mexsudo]

thank you for your efforts.

Debian 11 is in the final stages of testing. I will sit and wait. Maybe we will get lucky and the official release will be compatible.

1. Conky development has moved here: https://github.com/brndnmtthws/conky
2. You might want to try a simple config first to see if the issue can be reproduced, e.g. the following:

   
   conky.config = {
   alignment = 'top_left',
   background = false,
   border_width = 1,
   cpu_avg_samples = 2,
   default_color = 'white',
   default_outline_color = 'white',
   default_shade_color = 'white',
   draw_borders = false,
   draw_graph_borders = true,
   draw_outline = false,
   draw_shades = false,
   use_xft = true,
   font = 'DejaVu Sans Mono:size=12',
   gap_x = 5,
   gap_y = 60,
   minimum_height = 5,
   minimum_width = 5,
   net_avg_samples = 2,
   no_buffers = true,
   out_to_console = false,
   out_to_stderr = false,
   extra_newline = false,
   own_window = true,
   own_window_class = 'Conky',
   own_window_type = 'desktop',
   stippled_borders = 0,
   update_interval = 1.0,
   uppercase = false,
   use_spacer = 'none',
   show_graph_scale = false,
   show_graph_range = false
   }

Replace eth0 with the actual network interface you on your system, from your screenshot above it should be `enp1s0`.

I also found this problem in my arch linux. I think it is not caused by distribution's version, because it conky can detect my device wlan0. I did some tests, the one is to directly show upspeedgraph wlan0 32,130 in conky.conf and it worked properly. So I think this problem may caused by conky ifaces.

It surely related to conky bug, see https://github.com/brndnmtthws/conky/issues/1109
