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.

I'm using Gentoo with systemd and a customized kernel, and additionally I have the /usr partition LUKS encrypted. Because /usr is absolutely essential for systemd to function, I configured dracut to make a specially crafted initrd which activates the luks lvm and prompts for the password to decrypt and mount /usr on startup before systemd init tries to run.

About a year or two ago, some update to dracut or some other dependency (assumption) caused the dracut generated initrd's to kernel panic. After multiple days of troubleshooting, I discovered that just copying forward an older initrd in /boot and naming it to match the new kernel, e.g. initramfs-6.6.38-gentoo.img , allows the system to boot normally .

So, my Gentoo is booting a kernel 6.6.something with a ramdisk generated in the 5.9 kernel era. I am dreading the day when this behavior breaks and I can no longer update my kernel 😳

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.
