Ubuntu 24.04 xrdp gui task icon shows, but not clickable

[strikegun79]

Hello,
I followed a lot of FAQs and many issues helps, but I can't fix it.
We are using Ubuntu 24.04 with xrdp for headless display manager.
emailproxy is installed in a venv and pip.

I installed all mentioned packages. read about 3 hours forum, issues etc.

But the emailproxy is running, no errors, Icon shows up, but than nothing. no menu or rightclick action.
The icon seems not correct either. it more like greyed out.

any one can help on that?

That looks a little bit like the icon, but clearly has display issues. Perhaps an issue in parsing its content.

Have you looked at the dependencies and setup section of the readme? There are a few Linux-specific previous issues here that may have a solution.

Apart from this, does the proxy work normally? If not, have you tried --no-gui mode?

Please could you enable --debug mode and post the proxy's log?

Hi, yes I checked all dependancies and setup.
checked for pystray and pywebview dependencies. the proxy's log looks good. no errors or missing libs.
with the --no-gui mode the same, but no icon. We need the gui for the MFA verification.

After starting emailproxy with: /home/otoboadmin/emailproxy-env/bin/emailproxy --debug --log-file /home/otoboadmin/emailproxy.log

I see this in the logs:

2025-04-01 13:30:14,851: Initialising Email OAuth 2.0 Proxy (version 2025-03-14) in debug mode from config file /home/otoboadmin/emailproxy.config

2025-04-01 13:30:14,855: Initialised Email OAuth 2.0 Proxy - listening for authentication requests. Connect your email client to begin

No problem as far. But the Icon looks like above in the screenshot.

The proxy uses pystray to build and display the icon. What happens if you try a basic pystray icon on its own? For example, what do you see with this sample from that project's usage page:

from pystray import Icon as icon, Menu as menu, MenuItem as item
from PIL import Image, ImageDraw

state = False

def create_image(width, height, color1, color2):
    image = Image.new('RGB', (width, height), color1)
    dc = ImageDraw.Draw(image)
    dc.rectangle((width // 2, 0, width, height // 2), fill=color2)
    dc.rectangle((0, height // 2, width // 2, height), fill=color2)
    return image

def on_clicked(icon, item):
    global state
    state = not item.checked

icon = Icon('test name',
            icon=create_image(64, 64, 'black', 'white'),
            menu=menu(item('Checkable', on_clicked, checked=lambda item: state))).run()

Ok, after I started the venv, I can use the pystray. The Icon looks now like this, but has no interaction and no menu.

Update:
I installed python3-gi over APT.
Then I edited for the venv the pyvenv.cfg with:
echo "include-system-site-packages = true" > /home/otoboadmin/emailproxy-env/pyvenv.cfg

Now the test2.py works

(emailproxy-env) otoboadmin@atotobo:~$ python3 test2.py
Gtk-Message: 11:41:18.669: Failed to load module "xapp-gtk3-module"
Gtk-Message: 11:41:18.669: Failed to load module "appmenu-gtk-module"

But it does works with emailproxy. There the icon is still dead.

[strikegun79]

Update:
Found my problem.
I also have to install the emailproxy[gui] over pip install in the venv

This is now my work through:

apt install python3-gi gir1.2-girepository-2.0 appmenu-gtk3-module
python3 -m venv emailproxy-env
echo "include-system-site-packages = true" > /home/otoboadmin/emailproxy-env/pyvenv.cfg
source /home/otoboadmin/emailproxy-env/bin/activate
pip install pystray pillow pywebview timeago proxy_tools
pip install emailproxy[gui]
source /home/otoboadmin/emailproxy-env/bin/activate
/home/otoboadmin/emailproxy-env/bin/emailproxy --debug --log-file /home/otoboadmin/emailproxy.log

Now is the icon accessable.
For me its solved. is that something for the documentation? Or was I to nooby? ;-)

Thanks for following up – I'm glad this was resolved. The intent is that pip install emailproxy[gui] installs all dependencies, as explained in the readme. I'll link to this issue alongside the others already in the documentation in case others face the same problem.
