I apologize for a broad title, but I'm not sure about causality chain in this case. I'm searching for Ubuntu flavor with a stable UI. Old-fashioned is not an issue for me. I used Ubuntu MATE years ago in my short encounters with Linux and I liked it. Recently, I dropped Windows and started using Linux exclusively. I'm on a standard Ubuntu 18.04.5 distribution, which was a somewhat forced choice, but I'm not a big fan of newer versions of Gnome.
I'm trying to move my daily working environment to Ubuntu MATE 18.04 and 20.04.2 (I need both). Here is the issue I just encountered. Ubuntu MATE 20.04.2 installed just fine and my Canon MF232W printer works - hurray! I wanted to install the newest version of Okular, which is only available as binaries through flatpack or snap. I installed Plasma's Discover, thinking that it will be an easy way to manage flatpacks and snaps without using the command line. After installation, Discover notified me that system updates are available, so I went for it. Rebooting the system after updates, shows that Nvidia driver is dead and my display is in low resolution and different orientation. Here are the questions I have:
- Are software updates by different means equivalent, e.g. Discover,
sudo apt update && sudo apt upgrade
and Software Updater? - Is there a procedure to avoid Nvidia driver getting disabled? I remember this happening multiple times when evaluating different Linux distributions.
- What is the most convenient way for occasional flatpack or snap package installation? Discover, which I just installed, didn't find flatpack or snap version of Okular, even though I checked enable snap and flatpack backends.
