Quick Re-Set for Desktop using xrandr

All too often when installing a game, a problem occurs that halts the game and does not restore my desktop to the proper size.

To look at what I started with and what I wound up with is simple.

$ xrandr
Screen 0: minimum 8 x 8, current 5120 x 1080, maximum 32767 x 32767
DVI-D-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.02*+ 75.02
1280x960 60.00
1152x864 75.00
1024x768 75.03 70.07 60.00
800x600 75.00 72.19 60.32 56.25
640x480 75.00 72.81 59.94
HDMI-0 connected primary 2560x1080+1280+0 (normal left inverted right x axis y axis) 798mm x 334mm
2560x1080 60.00*+
1920x1080 60.00 59.94 50.00 29.97 60.05 60.00 50.04
1680x1050 59.95
1600x900 60.00
1280x1024 75.02 60.02
1280x720 60.00 59.94 50.00
1152x864 75.00
1024x768 75.03 60.00
800x600 75.00 60.32
720x576 50.00
720x480 59.94
640x480 75.00 59.94 59.93
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 connected 1280x1024+3840+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.02*+ 75.02
1280x960 60.00
1152x864 75.00
1024x768 75.03 70.07 60.00
800x600 75.00 72.19 60.32 56.25

640x480 75.00 72.81 59.94

With one monitor, all I had to do was create a small shell script named restore to change the display back to the resolution I normally use, place it in ~/bin and make it executable.

#!/bin/sh
xrandr -s 2560x1024

Multiple monitors should be doable with xrandr, but I need to figure out the syntax. Have a look here.

Here's what I have:
$ xrandr --listmonitors
Monitors: 3
0: +*HDMI-0 2560/798x1080/334+1280+0 HDMI-0
1: +DVI-D-0 1280/376x1024/301+0+0 DVI-D-0
2: +DP-1 1280/376x1024/301+3840+0 DP-1

HDMI-0 is in the center; DVI-D-0 is to the left of it and DP-1 is to the right of it.

DOS4GW.EXE Version 2.01a and Alternative DOS Extenders

DOS4GW.EXE The Tenberry DOS extender DOS4GW.EXE was used by many early DOS games. I still enjoy playing many of these games and DOS4GW.EXE is usable with DOSBox , so they can be played on Linux. However, the version of DOS4GW.EXE that was included with the game was whatever was current at the time. The most recent version that includes many bugfixes that possibly affected the games when used with DOSBox have been fixed in the latest version, 2.01a. It's not free at US$49, but you can downloaded it here . Simply substitute it for whatever version of DOS4GW.EXE your game provided and enjoy the bug-fixed goodness. Tenberry also makes a "high-performance" "pro" version of DOS4GW.EXE, but it costs $300. I think that they could sell quite a few of these to hobby users (since, you know, DOS is dead) for US$5. Open Souce to the Rescue There are better performing, free and Open Source alternatives available and worth a look. DPMI Explained Let's unders
