Indicator does not display properly when using KDE Plasma desktop

[Chito Tuason]

Switching to KDE Plasma desktop, the System Load Indicator appears on the task bar. It is not displayed properly but I think it is getting updated.

Yeah I know. There are two problems actually:
- the menu items do not get updated (only for the beta version)
- the plasma indicator thingy can't find the icon

Status update:
- the menu items *do* get updated
- the plasma indicator thingy still can't find the icon

Hello,

Following Ji M's instructions, I’ve just installed v.0.4 of System Load Indicator into my LInux Mint 17.1 KDE on a rather new, powerful, home, mini-tower computer. I’ve installed the repository-based version, 0.3, in Ubuntu Cinnamon, too. I have it installed in regular Ubuntu (Unity) and Linux Mint 17.1-Mate. The graphs display fine in Unity and Mate, but they don’t show up in either Cinnamon or KDE.

I’ve put an icon in the bottom panel of the Mint 17.1 KDE, but it appears as just a cli-display icon, and clicking does nothing; it appears to be trying to run it, but after a short while, as 20 seconds (I haven’t counted), the evidence of its trying disappears. I managed also to get a white, generic page icon in the system tray which, if I right click it, I get a popup numerical listing of the SLI’s monitors.

Do you know what to do or if anything can be done to display the graphs in my Mint KDE and Ubuntu Cinnamon DEs?

Still not working on Ubuntu 16.04 and Plasma 5.5
Indicator blinks but doesn't show actual values.
KDE's alternatives aren't as good as this indicator.

Installed from CLI without incident. Following conclusion of installation, attempted to launch from Terminal with following error:

(indicator-multiload:15702): Gdk-CRITICAL **: 13:01:08.550: gdk_window_thaw_toplevel_updates: assertion 'window->update_and_descendants_freeze_count > 0' failed

Despite above error, able to launch from menu, however no icon appears in system tray. On a hunch, I Right clicked on an unusually large,open area in systray which displayed context menu for the application. From appearances, seems to be working nominally except for the missing (hidden) systray icon.

Please evaluate information and advise as to possible solution.

I recently switched to KDE 5.16.2 on Manjaro and ran into the same issue. My research suggests that KDE forces a fixed (or maximum) height/width for AppIndicators and is unable to render the icon produced by this indicator.

The indicator itself works, as the context menu appears and you can see the graphs being produced in /run/user/1000/multiload-icons-*/

I tried an applet from a similar project, multiload-ng, which has the same issue.
https://udda.github.io/multiload-ng/

However, the "systray" version of multiload-ng and it works, although it lacks the context menu of indicator-multiload, which I really liked! I did try [indicator-multiload --trayicon] to load the 'systray' version of the indicator, but it yields the same result. I think multiload-ng works as it creates multiple 'tray icons' and lets the desktop environment handle the size/order, which might be a workaround for this indicator to display under KDE.
