Old games with 4x3 aspect ratio & low res on fullHD monitor

[ilya]

Could you help me with 2 more problems in all the old games through wine?

1 If the game is written under a 4x3 ratio and starts on a 16x9 monitor in full screen mode, it stretches to the entire monitor without preserving the aspect ratio. Is it possible to somehow display in full screen mode in the center with the preservation aspect ratio

2 After the game is over, if it has changed the desktop to low resolution, it still does not go back fullHD resolution.

Can these problems be solved

Try running the game in an emulated virtual desktop (set it on the Graphics tab in winecfg).

Try running the game in an emulated virtual desktop (set it on the Graphics tab in winecfg).

This method only helps to launch a full-screen application in the window.
But it is necessary that the application is launched on a full screen, but with the preservation of proportions, and it is desirable to remember and return the resolution of the desktop, as in Windows. Are there any similar tools in wine, can there be third-party utilities for this?

The virtual desktop is Wine's tool for this. Set it to the resolution the application wants, and the app should launch full screen in the virtual desktop to those proportions, without affecting the resolution of your desktop.

As for not restoring the desktop resolution after running a fullscreen app, that's a longstanding bug in the X server.

Either we do not understand each other, or it works differently for me.
I setup emulate the desktop 1024x768 and run the application.

At me after a start there is a virtual desktop and the application is launched, it starts to think that it is in full screen mode.
But in fact, for me, it's just a window. It's clear that the window will not change the desktop resolution, but I need it not to be a window, but a full-screen application, so that it retains the proportions, that is, it does not use all 1920x1080, but only 1440x1080 with center alignment. And then at the exit, including the emergency exit, returned a resolution of 1920x1080.

Thank you for links on bug reports. My second problem is bug xorg.

And what about the implementation of the keep aspect ratio option?
In windows this is either by default or is configured in video drivers.
I use an open driver (nouveau, intel, redionSI, amdgpu).
Is this the problem of video drivers? Where to write or where to find the appropriate bug report?

Take a look at: Ubuntu Forums: Maintaining aspect ratio in fullscreen.
NB: this hack only applies to the Nvidia binary driver.

As for restoring your native desktop resolution. This can also be hacked around for older games - running under Wine.
Something like a script pre-launching: wineserver and waiting for the wineserver process to end and then restoring your stock setup - with xrandr.

One day we might even get an SDL-2 shim for Wine to handle desktop resolution changes...

xrandr --output VGA1 --mode 1024x768 --panning 1024x768 --transform 1.33333333,0,-171,0,1,0,0,0,1 && wine /ILYA/Games/ER/Legacy\ Interactive/ER/ER.exe ; xrandr --output VGA1 --mode 1920x1080 --panning 1920x1080 --scale 1x1
Where -171 = -round((1024 * 1.3333333 - 1024) / 2)

Was it not possible to do something similar in the tab, next to the virtual desktop, or even an option that would automatically do this by defining the current display of the desktop resolution and the resolution in which the application is trying to switch?

The script is placed in the directory with the executable file of the game and is also called as this file but without ".exe".
The script disassembles the video mode necessary for this game and comments all the others.

Code: Select all

#!/bin/sh
vga=`xrandr | grep -P " connected (primary )?\d+" | sed -e "s/\(\w\+\) .*/\1/"`
if xrandr --output $vga --set "scaling mode" "Full aspect" 2>/dev/null;then
	wine "$0".exe
else
	#res=640x480 && off=107
	#res=800x600 && off=133
	#res=1024x768 && off=171
	#res=1152x864 && off=192
	#res=1280x960 && off=213
	res=1440x1080 && off=240
	xrandr --output $vga --mode $res --panning $res --transform 1.33333333,0,-$off,0,1,0,0,0,1 && wine "$0".exe ; xrandr --output $vga --auto --panning 0x0 --scale 1x1
fi

It is also need checking all of the modes are supported by your monitor.

Code: Select all

xrandr

If the required modes are not available, you can add them manually by editing the Xorg configuration file.

/etc/X11/xorg.conf.d/50-monitor.conf

Code: Select all

Section "Monitor"
	Identifier "VGA1"
	Modeline "1280x960"  101.25  1280 1360 1488 1696  960 963 967 996 -hsync +vsync
	Modeline "1280x960"  130.00  1280 1368 1504 1728  960 963 967 1005 -hsync +vsync
	Modeline "1440x1080"  129.00  1440 1528 1680 1920  1080 1083 1087 1120 -hsync +vsync
EndSection

Where Identifier "VGA1" is the name of the output, you can determine by executing xradr;
Modeline ... parameters of the added mode.
These parameters are determined by the corresponding cvt calls with the transmitted resolution and frequency.
"_60.00" from the first parameter is cut out.

Code: Select all

cvt 1280 960 60
cvt 1280 960 75
cvt 1440 1080 60

If the monitor supports "scaling mode" "Full aspect" then the file is running via wine without changes.
If not, then the screen is corrected through xrandr.
And then returns the screen to the normal state.
