Why .deb packages never add desktop and start menu shortcuts, even if installed software is graphical UI only?

Sorry if it’s a lame question but why installing software from .deb package never seems to add any shortcuts to desktop and start menu, even if installed software is a graphical UI program?

For example, try installing Chrome on fresh Ubuntu 20.20. You go to official chrome page where it will point you to the latest .deb package. Great. You download and install the package. Perfect. But then what?

No shortcut on desktop, no icon in start menu and -if you happened to close the package installer window – you even have no clue where the software was installed.

Is this fundamentally impossible due to some technical limitations of the package manager or is it just laziness of package creators which don’t care about auto creating those launcher shortcuts on desktop?

I’ve just installed new Ubuntu, installed Chrome and was puzzled how counter-intuitive and user-unfriendly the whole process is. I had to 1) find where the stuff from .deb was physically installed 2) create launcher manually 3) assign an icon to the shortcut manually.

mouse and keyboard not working on Ubuntu 20.04

I’m sorry I’m new to Ubuntu so I’ll try be as descriptive as possible.
At the moment my mouse is working when plugged into a specific USB port on the back of my PC. However when I move it to another port it doesn’t work. If I plug my keyboard into this same USB port then the keyboard will work and the mouse won’t. I have my system on a dual boot at the moment and I know for a fact that both the mouse and keyboard do work, it’s only when I reach the login screen that I have issues with my keyboard/mouse. I have tried other solutions given on this site and elsewhere but they don’t seem to work.
Like I said I’m new to Ubuntu and Linux as a whole so I’m sorry if this is an obvious question.

Cannot use buttons on MPOW Headphones to pause video/audio Ubuntu 20.04

I use MPOW headphones to listen to podcasts on my HP Pavilion Laptop while I work, and while on windows 10, I was able to use the buttons on my headphones to pause and play the audio as I pleased. Upon switching to Ubuntu 20.04, pressing the buttons on my headphones no longer works. The audio is just fine, it is the pause/play feature through the headphones that no longer works. Does anyone have solutions to my predicament?

Ubuntu 20.04 looses WiFi adaptor

I just did a fresh install of Ubuntu 20.04 on an old computer and after 1-2H of usage the WiFi drops and there is no way to connect it back since the prefs show an error message: No wifi adaptor found. (Works again after a reboot).

FYI: The wifi card is an Atheros AR9485 (internal) and is running using ath9k & everything is up-to-date

Why is Ubuntu 20.04 not registering ethernet on my Raspberry Pi?

When the Raspberry Pi boots up, Ubuntu 20.04 says the following:
Net: No ethernet found.
starting USB…
No working controllers found

It continues to boot up, but this means that I can not install a desktop environment on it. The ethernet port and cable work fine, and the Raspberry Pi ethernet jack lights up when the cable is plugged in. How do I get ethernet to be recognized?
Thanks!

Ubunutu 20.04 Gnome shell crashing on enabling Extensons from Gnome Tweak Tool

I recently upgraded from Ubuntu 18.04 to 20.04
Everything is working fine except the Extensions

I tried enabling them using Gnome Tweaks Tool

Tweak tools -> Extensions Sidebar -> Top right corner
Gnome Tweaks Tools

But as soon as I toggle that, the shell crashes and I see this screen.
Shell Crashes

I am forced to logout and then login again. And then extensions are disabled again.

I tried enabing them even through dconf editior but the same thing happens. The shell crashes immidiately.

I tried looking for solutions but it seems like the issue is experienced by extremely few people. I could only find one question for it on Reddit(no solutions on it yet).

Does anyone know what the issue is about and if there is a fix for it? I am not able to use extensions and this is really bothering me. I am ready to provide any further details necessary to fix this issue

VNC on Ubuntu 20.04 without monitor

Since couple of days I am trying to set VNC Connection with my “server” Ubuntu desktop 20.04. I want to use it as remote workstation and I want to use gnome3 environment, VNC Connect or NoMachine (for better management). Everything works well as long as monitor is attached. As soon as I remove monitor – connection breaks. Ok, that’s how it works. I have created dummy screen…

sudo apt-get install xserver-xorg-video-dummy

With config based on this post:

Add Fake Display when No Monitor is Plugged In

I can access server, but it stuck on login screen with password prompt. When I put password, nothing happen. Still login screen with password prompt.

If anybody have any idea – please, help.

Regards
