Marco Montevechi Filho's questions

I am using ubuntu 22.04 with xfce.

I want to put a script that does:

ln -fs /path/to/folder ~/

Everytime a user logs in via graphical remote access (particularly, I'm using remmina). I tried /etc/profile.d, /etc/bash.bashrc, /etc/X11/Xsession.d, /etc/gdm3/PostLogin/Default.sample... nothing works. Maybe I need to restart some service?

I found this but this is user-specific. Same for this. Several other forum discussions led me nowhere.

Thanks in advance for any help to this hopeless soul.

I have a machine running Ubuntu 20.04 and made a .desktop file. I tested it in my desktop and it worked, so i copied it to all existent users and did

sudo su; cd /etc/skel/; mkdir Desktop;
cp /home/MyUser/Desktop/MyIcon.desktop ./

So that all new users have access to the icon (the application is executable by all). However, when looking at what appears to other users, it is clearly not an executable .desktop file (comparison for what appears to my user and other users in images below).

what appears for my user What appears to other users

It seems doing what this answer suggests solves the issue, but i need to be the other_user doing this (where other_user is the user that will have the icon as an executable). So the only thing that can automatize the creation and correct configuration of the icon for new and existent users that comes to my mind is doing:

cd /path/to/other/user/Desktop
sudo su -l OtherUser
gio set app.desktop metadata::trusted true

for existent users and, for new future users:

cd /etc/skel/

and adding

gio set ~/Desktop/app.desktop metadata::trusted true

to .bashrc. This does not feel intelligent. Also, the sudo su -l option returns me an error:

gio: Setting attribute metadata::trusted not supported

Is there a better way for new users and a working way for already existent users?

Edit to add response to cbugk comment: content of file is in the form:

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false
Exec=/usr/local/path/to/executable
Name=Name of application
Icon=/usr/local/path/to/image.png

I'm developing a graphical application with PyDM. The application is spawned by just executing its .py file, so it has no .desktop file.

For some reason, the interaction between PyDM and PyQT seems to override the PyQT ApplicationName methods and properties, so I can't dynamically or even statically define it via python code in any way I could think of.

So I'm now searching for a "Ubuntonic" instead of a pythonic way of changing the tooltip that shows when you hover your mouse above the application icon:

All solutions I found until now involve modifying its .desktop file, which is something I can't do for several reasons. Is there any other way to do this?

Solutions I found until now:

• How can I edit tooltips for unity launcher icons?

• How to safely change the names of items in the system settings
