Attempting to stretch a native windowed game to fill screen like borderless windowed screen; no success.
 

I am trying to fix an older title to run in Windowed Full screen (since the actual Resolution Changing Full screen Mode seems to not function and stays in it's aspect ratio.

I've searched high and low, but found nothing.

What I specifically need is something that removes Window Borders ("Undecorate") and something that forcefully stretches a 4:3 Window to an "Alt-Tabable" 16:9 Screen that fills up past various Menu Bars and such.

I do this in Windows 7 with a program called Fullscreenizer. https://www.howtogeek.com/324835/how...windowed-mode/

I am using Ubuntu 18.04.1 LTS with XFCE and Compiz.

I should also mention that Fullscreenizer seems to run well in Wine (Not that it helps me with Software outside Wine, but it does its job).

it depends on the game and how it is implemented.
sometimes it simply won't work - especially the stretching part - i have one or two games like that.
others only allow to go fullscreen through some config file setting or a command line option.
read the docs.

lol I knew that
 

I am aware of this.

I was looking for a way to do this with the WM (Compiz) or maybe even some sort of "xstretcher" that exists out there.

but that won't help since some game engines paint on the screen directly, circumventing window management.

instead of guessing around, why don't you tell us

• which game you're talking about
• what your initial research (read the docs) and troubleshooting got you so far

Alas, this is no simple issue. This game is actually really dang cool.
 

The specific title I am looking to "alter" is "Liquid War". It's from the Universe Repository.

As with all obscure fun games, you get it.
 

I've literally nothing at all for the game about this.

sorry, that's not good enough.

please open a terminal, and, assuming the package name is "liquidwar", enter this command and post its output:

I give you, THE OUTPUT!!!

hooray, liquidwar has a man page!
should prove helpful.

apparently there's also /usr/share/doc/liquidwar, but it might be empty.
maybe there's a separate package liquidwar-docs?
