I want to use the Micro text editor as the default application to open various text files, but when I try to do the usual procedure:
Left-click > Properties > Open With...
I see that Micro doesn't exist as an option.
How can I do that?
How can I stop the Alt key from triggering the menu bar of applications in Ubuntu 19.10?
I know that there are these post 1, post 2, and post 3, as well as https://docs.substance3d.com/spdoc/impossible-to-use-the-alt-keyboard-shortcut-on-linux-143720782.html but those solutions are no longer applicable. I did try searching for a similar option to the one in the answer of those questions but with no success.
I have an SSD in which I already have Ubuntu 19.10 and I also have a HDD in which I want to install Windows 10.
I read all the available relevant questions about this in here, most of which where confusing at best, but I thought to give it a shot and just do the normal procedure of the installation without giving it much more thought.
After the installation of Windows 10 was complete it worked but I had the problem of Windows boot loader being on the SSD alongside Ubuntu. I want the two drives to be as separate as possible so that was not an option for me.
I formatted the HDD and deleted the Windows boot loader from the SSD so I want to do this procedure again but maintaining the two OSes separate.
So how can I do this correctly? I don't particularly care about GRUB as I am perfectly happy to get into BIOS and pick the drive I want to boot from. I also read the answer of a similar question in here suggesting that unplugging the one drive during the installation and then plugging it back in was a bad idea because the OS in the unplugged drive may not be recognized after that. So want to avoid that.
I am trying to use KOrganizer but it misbehaves completely.
First of all when I create an event and specify a time for it, then after I press apply the hour changes automatically to 12 o clock every time.
Also I can only see events at the agenda section. They don't appear anywhere else.
It is the first time trying to use KOrganizer so I don't know if I am making any mistake. It seems weird to be that much broken.
I am redirecting the output of the terminal to a file using:
Command > File.txt
but the contents of the file appear like this:
What is the problem? How can I make them appear normal?
I have heard that Ubuntu MATE is more lightweight that Ubuntu. My question is does that mean that the first one uses less system resources leaving more of them for use from the user or does it handle all the processes in a different manner too?
What I mean is if I have, let's say, Firefox running with 20 tabs in both Ubuntu MATE and Ubuntu, will there be a difference in the system resources used?
Up to now I thought that Firefox will simply use the same resources in both flavors, but in the first one there will be more of them as the desktop environment is more lightweight.
I am trying to toggle the desktop by going to the lower left corner. I used the Hotcorners from the Unity Tweak Tool by setting that corner to "Toggle Desktop" but it doesn't work. The other functions for that corner work as they should though. Why is that happening?
If you have any other alternatives to succeed that feel free to mention them.
There are some files and folders that have a red X on them. What are those? What does that red X represent?
I would like to rename all files in a folder so to have consecutive numbers. For instance:
1.png
2.png
3.png
etc
I know there is the rename command and I know there are DOZENS of similar questions in here but I can't find the way.

While I was turning on my PC today (Ubuntu 14.04), and before the log in screen appeared, there was for just a moment a screen about NVIDIA which hadn't appeared before. It wasn't an error message or text but the logo of NVIDIA. The screen flashed so quick that I didn't get to see it properly though. Was there any updates that changed the way that NVIDIA advertises the drivers that the PC uses?
I have installed MySQL in Ubuntu 14.04 but I can't find the mysql.h file in any directory. I don't mean that the compiler can't find it, as mentioned in countless other questions, here but I can't find the actual file. Why is that? Where can I find it?
I want to learn how to add and remove a directory/file from the PATH but there are hundred answers and a lot of them are contradictory (or so I believe).
I have found answers that suggest editing .profile and others that say that this file is no longer supported for this job (or that is what I understand).
I have found answers that suggest editing /etc/environment.
Some other answers suggest editing '~/.bashrc' file.
Also I have found some answers suggesting writing something like export PATH=...
Currently I don't know which of these suggestions are correct, which of them are advisable to be used without causing any side effects in my system and I haven't got any idea hot to remove a directory/file from the PATH.
So how can I add and remove a directory/file from the PATH correctly?
I would like either a program or more preferably a way to log the disk usage.
In order to explain what I mean, when someone installs Ubuntu there are approximately 4.5 GB of disk used. Then when you install/uninstall programs this usage increases or decreases.
What I want is a way to log automatically the current disk that is used in a txt file when there is a change (something is installed/saved or uninstalled/deleted) with the time and date that this change occurred.
How can I get in Ubuntu 14.04 a list of every program I have installed with its size but with chronological order? Is there a way?
It is important to mention that I have found a lot of similar questions in here and they were not helpful.
I turned off my PC (Ubuntu 14.04) and when I turned it back on the fonts had changed (file names, folder names etc.). Why did this happen and how can I change the fonts again?
Now is this way:
I am trying to install something and among the steps there was this one:
"Place it on your $PATH"
What does this mean? What is that?
I have searched both this site and on Google but everyone just takes it for granted!
I have installed Jitsi and as I have read that is highly customizable I want to change the font size as it is really small. But I don't want to configure it via the properties of Ubuntu and enlarge the fonts everywhere. I just want to change the font size in Jitsi. How can I do that?
I would like to take a photo from my webcam. As I moved from Windows to Ubuntu I wonder if there is a built-in way to achieve this or I need special software. If so can you suggest a good one?
Sometimes when I install software using the sudo apt-get install <package> command the package may take minutes to be installed and in the end it may occupy some gb of space. If I uninstall it using sudo apt-get purge <package> then it may be uninstalled in seconds and very little space (some kb or mb) may be removed from the original that it occupied when installed! Obviously that means that this is not a clean uninstall and that my pc is full of undeleted files. Why is that happening and how should I uninstall packages cleanly and fully?
I would like to open a file that already exists while already in Vim.
What is the command to do this?
