Since Ubuntustudio switched to the plasma-desktop with 20.10 we have a new organized application menu which divides the games category in subcategories.
This is nice if one install a lot of games. But it increases the number of clicks you need to launch a game. I install or play games only occasionally, so it makes more sense for me to have all games in the games category and not in any subcategory.
How can I change my menu to display all games in the games category?
Playing around in my system, I stumbled upon
~$ echo $XDG_DATA_DIRS
/usr/share/ubuntustudio:/usr/share/xfce4:/usr/local/share:/usr/share:/var/lib/snapd/desktop:/usr/share
Asking myself why /usr/share is twice in the path I found out that the following snippet in
/etc/alternatinves/x-session-manager which is a link to /usr/bin/startxfce4 is responsible:
#!/bin/sh
.
.
.
if test "x$XDG_DATA_DIRS" = "x"
then
if test "x/usr/share" = "x/usr/local/share" -o "x/usr/share" = "x/usr/share"; then
XDG_DATA_DIRS="/usr/local/share:/usr/share"
else
XDG_DATA_DIRS="/usr/share:/usr/local/share:/usr/share"
fi
else
XDG_DATA_DIRS="$XDG_DATA_DIRS:/usr/share"
fi
export XDG_DATA_DIRS
.
.
.
When I look at the line
if test "x/usr/share" = "x/usr/local/share" -o "x/usr/share" = "x/usr/share"; then
I have difficulties to understand this if-statement, for me it looks like a comparison of strings where the first one is always false and the second one is always true.
Combined with a logical or the test always evaluates to true, so I could shorten the line to
if true; then or I could say I don't need an if-statement at all.
Where is my mistake? Or is it written like this to confuse beginners like me?
~$ echo $'\'test'
'test
man bash says:
Enclosing characters in single quotes preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash.
Why does it work in the echo-command then?
Whenever I switch a video in Firefox to full screen, a message appears at the top edge of the screen, that the website is full screen now.
I find this quite annoying and unnecessary as I am the one switching to full screen. Is there a way to disable this message?
