tell me the most ass over backward shit you do to keep your system chugging?
here's mine:
sway struggles with my dual monitors, when my screen powers off and back on it causes sway to crash.
system service 'switch-to-tty1.service'

[Unit]
Description=Switch to tty1 on resume
After=suspend.target

[Service]
Type=simple
ExecStart=/usr/local/bin/switch-to-tty1.sh

[Install]
WantedBy=suspend.target

'switch-to-tty1.service' executes '/usr/local/bin/switch-to-tty1.sh' and send user to tty1

#!/bin/bash
# Switch to tty1
chvt 1

.bashrc login from tty1 then kicks user to tty2 and logs out tty1.

if [[ "$(tty)" == "/dev/tty1" ]]; then
    chvt 2
    logout
fi

also tty2 is blocked from keyboard inputs (Alt+Ctrl+F2) so its a somewhat secure lock-screen which on sway lock-screen aren't great.

Here's a few of the micro-hacks that I've hacked up in the past.

A 2-line script to chroot into Debian when logging in as a certain user on FreeBSD.

#!/bin/sh  

clear  
doas chroot /linux /bin/login

I didn't have an IDE, so I just made a script called ide which runs Vim, and then compiles the code and makes it executable.

#!/bin/sh
#Works only for C
vim $1.c && cc -O3 -Wall -Werror -Wno-unused-result $1.c -o $1
#MODE=`stat -f "%OLp" $1`
if ("stat -f "%OLp" $1 | grep -e 6 -e 4 -e 2") then
	chmod +x $1
fi

This thing, called demoronize, which does what it says in the comments

#!/bin/sh

#dos2unix -O -e -s $1 | sed 's/    /	/g' | sed 's/“/"/g' | sed 's/”/"/g'
cat $1 | sed 's/    /	/g' | sed 's/“/"/g' | sed 's/”/"/g'
#Convert DOS line endings to Unix ones and add a final newline if there isn't one,
#replace sequence of 4 spaces with tab,
#and replace "smart" quotes with normal ones

I just keep those ones for historical value, but there's one hack I use every day. My keyboard doesn't have a function key (Fn), so I use the Super/Windows key instead.
I have xdotool keyup Super_L keyup Super_R keyup F4 key XF86Sleep bound to a custom keyboard shortcut. It unpresses the keys used for the shortcut (Super + F4), then presses the sleep key.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
