no tray icon (xfce4-power-manager 1.7.1)

The tray icon for xfce4-power-manager gets a "no icon" symbol rather than an actual icon. the xfce4-power-manager-plugin for the xfce4-panel is fine.

screenshot attached

changed title from no try icon (xfce4-power-manager 1.7.1) to no tray icon (xfce4-power-manager 1.7.1)

I think this is an icon theme issue, mostly.

the icon theme in my screenshot is "obsidian", but the issue also crops up with adwaita (at least debian 10's adwaita). papirus works OK.

one other note, the icon in the systray does not change when Appearance is used to change icon themes.

Can you please post the output of upower -d ?

added 3. Need Info label

Screen with latest git-version:

I'm getting the same issue on Debian testing, with XFCE 4.16.

also tested with elementary-xfce-icon-theme & Adwaita. No icons on tray

Well on my end upower results in:

So the second device for DisplayDevice calls the following icon:

battery-missing-symbolic.

That would explain why it is shown. So mouse_hidpp_battery_0 is totally ignored.

I am using XFCE on Manjaro 20.2.1. The power settings manager icon on the taskbar is missing. The log is the result of upower -d.

I am using Xfce 4.16 on Manjaro 20.2.1. After the last Manjaro update (yesterday), I have the hicolor icon () instead of the former elementary Xfce dark icon (). My upower -d output:

With XFCE 4.16 update the tray icon of power managment is missing for me too.

upower-d

Same problem on Archlinux since Xfce 4.16 update.

I couldn't reproduce this so far, because it seems this only happens in very specific states and only in the trayicon (the panel plugin works fine).

I'll try to take a look at this.

I have made the update on 2021/01/19. I used the console on terminal window. The update was from XFCE 4.14 to 4.16.

Well, the issue is as @ochosi already pointed out: the tray-icon only. More or less an edge case, mostly seen on desktop PCs. Laptops might use hicolor icons, as the icon-themes might not have adopted to the new icon sets. I'm sure there might be a solution for it.

Nope, I am having this issue on a laptop as well.

On my desktop (Manjaro 20.2.1-1 with xfce just updated to 4.16.0-1 three days ago on 19.Jan.2021, theme Matcha-sea, Icons Papirus-Maia) the correct icon is shown in the settings dialogue for the Status Tray-Extension.

(The three other icons are shown correctly in the tray instead.) But in the tray there is a 'no icon' icon. This does not change with another colour theme or different icon theme. Output of upower -d attached. ASRock-Q1900B.txt
For a novice user this would be quite irritatiing, but it also looks ugly in a "stable" release. I'd really wish this to be fixed. On the Manjaro forum in the thread about the 19.Jan.-update there's quite a lot of reports like this.

On my notebook there also seems to be an incorrect size icon compared to the others in the tray - but here it indicates correctly the function - at least; and also when running on battery instead of the power supply - upower -d attached. DELL_Latitude_E5470.txt

this tray icon thing is easy to reproduce. it happens when the icon theme does not provide the charget status icons.

does xfce4-power-manager not use fallback icons for the charge percentage status icons when those icons are not provided by a theme?

on my system, I installed a newer version of adwaita, which supplied the icons, and which get used when my otherwise chosen icon theme does not provide them.

As a general note: if you're using the xfce4-panel don't use the trayicon. It's really the legacy option I left in to potentially enable users of other or mixed desktop environment setups to use xfce4-power-manager.

The panel plugin shouldn't have this regression.

@ochosi if tray icon is legacy and not wanted anymore in XFCE, why not disable it then, when a XFCE session gets detected?

It is disabled by default. If the panel plugin is detected, the systray gets disabled automatically and the default upstream panel layout contains the power manager panel plugin.

I've org.xfce.powermanager added later to the panel, but still the tray is active. So there is no switch to disable it. Additionally there is xfce4-battery-plugin, which also shows no icon and reports battery is empty on a desktop, which doesn't have a battery. So as I see it: Desktop PCs seem to got forgotten with this update. Most reports I've are from desktop users on a PC. Laptops are more or less fine.

No, there is a setting to disable the systray in the preferences dialog of xfce4-power-manager. Also, the systray will be hidden after restarting your session automatically if you add the plugin.

Desktops show a specific icon ac-adapter-symbolic, so no, they have not been forgotten.

I see. However, wouldn't it not been better to disable the function completely when xfce as session is running. In the settings menu I can enable it again, logout, and at relogin the tray icon is disabled. When I remove the panel plugin, it stays. Especially if you don't have the panel plugin enabled from 4.14 you will face that bug.

Presentation Mode is AFAIK only to activate via left-click - menu switch on whichever of Tray icon or XFCE Panel plugin is active - if this setting is easily accessible somewhere else, please, advise! I don't see it in the Power settings.

As for my desktop on an ASRockQ1900B I can report that the tray icon is 'no icon' as reported above, the plugin shows a 'battery charging' icon, not the former circle with a microscopic flash in the center. For me battery is intuitively more power-related than the other - anyway, it's a showing a battery on the desktop.
