In as far as Unity will continue to be maintained and supported for future Ubuntu versions, and in as far as you correctly add and remove software using the APT system, then no, you will not have problems with future updates.
Executor by raujonas, logo has a Sigma sign on it
does exactly what you want - I use it to ping a server and display and Up/Down arrow in the panel.
Install via https://extensions.gnome.org/ or use Tweaks > extensions
i think you need to
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoremove
sudo apt-get autoclean
or as a one liner
sudo apt-get update && sudo apt-get dist-upgrade && sudo apt-get autoremove && sudo apt-get autoclean
Thanks to the above answers I was able to find the executable evince
If you look under the
Help -> Advanced -> The Command Line
you can find the following:
The command line
To start the Document Viewer from the command line, type evince. You can open a specific file by typing the filename after the evince command:
I found this answer for Thunderbird 60, but it worked for me in 68. This may not provide all the flexibility you're after, but it will at least put the menu inside the title bar, which frees up some space.
To disable the title bar at Thunderbird 60, you need to go to system
menu Edit -> Preferences and choose Advanced tab. Then click at Config

For Ubuntu 18.04 and later (which have middle mouse button emulation enabled by default):
Create a script called disable-middle-button-emulation with following contents:
# to through all input devices
xinput list --id-only | while read id
# if this device supports middle button emulation, disable it (both evdev and libinput variants)
Open a termial:
Type in the following:
To show home folder at Desktop:
gsettings set org.gnome.shell.extensions.desktop-icons show-home true
To show Recycle bin(aka Trashcan) at Desktop:
gsettings set org.gnome.shell.extensions.desktop-icons show-trash true
This could be a permissions issue if all users don't have read access to the image.
From the folder containing the icon, you can run sudo chmod 744 icon.png to set permissions to rwxr--r--.
If the application was installed using snap, flatpak, or some other sandbox or pseudo-sandbox, then you should research how to create a custom icon for these applications,...
I guess the problem due to the upgrade from Ubuntu 18.04 to 20.40. I had a gnome-tweaks on my machine before the upgrade. I removed it, and I installed gnome-control-center. Something like the following could work:
sudo apt-get purge gnome-tweaks
sudo apt-get update
sudo apt-get install gnome-control-center
You could either use the following ways to install a package through a terminal:
sudo dpkg -i /path/to/deb.deb
There are actually 2 ways to install deb files with APT.
sudo apt install ./deb.deb
sudo apt install /path/to/deb.deb
Does not work any more on Ubuntu 18.04 and later, because ccsm works only on Unity desktop environment, and latest versions switched to GNOME.
As this site says, you can enter this line on your terminal:
xprop -f _NET_WM_WINDOW_OPACITY 32c -set _NET_WM_WINDOW_OPACITY `printf 0x%x $((0xfffffff * 80 / 100))`
Of course you can replace 80 in the command with ...
I came up with:
"xte 'keydown Alt_L' 'key Tab' 'sleep 1.5' 'keyup Alt_L'"
And off course, to install xte:
sudo apt-get install xautomation
Since I was looking to keep the switch window open to choose an application from the list myself, this was my final solution. Working pretty well so far.
