Hello everyone
I set the program windows to always open maximized
Hello @Maciek 
- Open it
- Maximize it
- Close it
- Reopen it and it should be maximized.
- Gnome saves the previous geometry, as I know
That is the default.
The method described by you works, but it works on windows of system programs. I have Opera installed and I need to maximize it every time
No, that works on all applications that use the GTK Framework. Opera don’t use GTK and have Chromium inside. Therefore you need set a parameter for that application since it doesn’t respect GTK.
Not sure, but maybe:
opera --help
gives you the parameters.
Firefox for example uses GTK and it works

I use --start-maximized with Chromium, so it’s likely to work for Opera. 
I edited the file by adding the phrase you provided. Unfortunately, it did not work.
GNU nano 6.4 /usr/share/applications/opera.desktop

Don’t edit anything in /usr/share/applications/ directly. Make a copy of it under ~/.local/share/applications/
You can also try just invoking the command in the terminal to make sure it works:
opera --start-maximized
Or see if it spits out any interesting messages or errors or warnings.
I think the order should be different:
Exec=opera --start-maximized %U
possibly even in quotes:
Exec="opera --start-maximized %U"
not sure at all - test the command in a terminal first

Good catch, and that’s true.
Hopefully, when they try to manually run it from a terminal, it’ll be more clear if it will even work in the first place.

neither of the recordings worked
… but apparently, Opera does not feature the same command line parameters as Chromium does
It was a guess.
What about:
this is another guess to see the available command line options
a guess, because I do not have it installed (yet)
these are all the available command line options:
opera --help

Sure it does.
aha - good to know
I didn’t find that piece of information in my short excuse for a “research”
and:
I said

I see you’re using GNOME, but in KDE you can specify “Rules” for certain windows, such as “start maximized”. Maybe there’s a setting in GNOME, or GNOME tweaks?
But first, see if you can get this to work from the terminal.
