Ubuntu – The pcmanfm-qt is dead on the Lubuntu 20.04

lubuntupcmanfmqt

I know it is so weird, but last night I set an image on my desktop background and delete the image, then I right-click on the desktop and press the desktop properties to change the style of background (center, stretch and etc) then the desktop properties stopped something like hanging on Windows.

Then a black window alerted something and I press yes without reading it. after that with right-click on the desktop I just see this:

Even some system applications don't work now. for example, I cannot take a screenshot.

Also, my pcmanfm-qt is dead completely, with the command line or clicking on the icon nothing happens.

I don't know what happens. and I have no idea how to fix it.

pcmanfm-qt does handle the background & much of the window for LXQt...

As you suggested it's the wallpaper change, change your wallpaper by editing

~/.config/pcmanfm-qt/lxqt/settings.conf

to point to a different file (change the Wallpaper= line)

Solution:

As a solution, I suggest you to get the PCManFM from the git repository and compile it yourself. In this way, You will at least get the tooltip and bigger file name's with bigger icons. Good luck.

Ubuntu – Double-clicking on .md or .mkd or .markdown files doesn’t open them in ReText but in the default text editor

You can probably try with mimeopen, which is a tool used to pair a specific mimetype with a particular application.

Use a file with .mkd extension as a parameter of mimeopen.

As an example:

$ mimeopen file.mkd 
Please choose a default application for files of type text/x-retext-markdown

    1) ReText  (retext)
    2) GNU Emacs 23  (emacs23)
    3) gedit  (gedit)
    4) LibreOffice Writer  (libreoffice-writer)
    5) Other...

use application #

Now, enter the number of the application (in this case, 1) and all .mkd files should now open in Retext.
