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.

    So I use a surface device with the Linux surface kernel, and there was (and probably still is) an issue where the type cover doesn’t properly rebind after being detached and re-attatched. To make matters worse, connecting other USB devices disconnected the type cover. My solution was to make a udev rule that detected if the keyboard is “removed” and then try to rebind it, effectively unplugging it and plugging it back in again in software.

      Did it work? There’s a huge chance of data corruption if you are copying the disk of a running system.

          That’s not even a bad idea then.

          One of my machines has a boot partition that’s a bit too small, on an otherwise LVM setup.

              Nah, it’ll be fine.

              I might have a large enough USB SSD laying around some where. I could probably use that instead.

              • extend VG with the USB PV
              • move LV’s to USB
              • shrink root LV
              • resize boot
              • move things back on a new internal PV

                  Does your FS support online resizing?

                  Yeah. I mainly use btrfs; it supports online growing and shrinking.

                  Be super careful about partition sizes. […]

                  I know. I have done plenty of same device partition resizing. I know the pit falls, and for safety shrink the FS to below what the LV is going to be.

                  Have backups.

                  Thanks for the reminder. I’ve been meaning to set up snapshot backups for this machine using rsnapshot as an experiment. I mainly use Dirvish

    sssd didn’t work well with my company’s AD server, which would cause repeated authentication failures until I restarted sssd. I rigged up a bash script which would restart sssd any time xscreensaver logged an auth fail.

    intel won’t allow its linux drivers to work above wifi 4 speeds in ap mode, so i created a kvm virtual windows machine with pci pass through on the wifi nic plus ip masquerade and now i’m getting wifi 6 speeds in ap mode.

        i wasn’t aware that you could use ndiswrapper on an access point; i’ll look into it.

        UPDATE: googles says that you can’t do this because ndiswrapper uses windows drivers that don’t support ap mode.

      Lots of laptops just use a removable m.2 wifi card. Have you considered replacing it with something thats properly supported? I know hardware costs money but not that much probably.

        It’s not a laptop; it’s a mini desktop that I obtained to serve as a wifi router; storage server; firewall; VPN; media server; remote file storage; and my cat’s favorite warm napping surface.

        the wifi nic is embedded on the motherboard and it was chosen since it included a high gain antenna; among other qualities.

        Wifi works fine if you use it in ordinary client mode w full Linux support and the hardware is capable of fully supporting ap mode in older Linux kernels; it’s just that Intel decided remove higher speed ap mode support in the latest versions of the driver to force people to buy thier more expensive wifi nics.

          It’s not a laptop and the hardware is fully capable of ap mode support in it’s older iteration if drivers; Intel made the decision to remove that capability in the recent versions of the driver.

    I’ve set Raspberry Pis to auto-reboot themselves at night if they are being used for headless network services that need to be available 24/7, just to clear out memory leaks or other things that may have gotten locked up. Not sure if that’s duct tape or just a standard practice. They aren’t the most stable things sometimes. They’re known for power supply and SD card issues.

      I did this with my sensors running in Pi picos.

      There was some wonkyness with some of the electrical stuff and since I have no idea how to debug that, I just restarted them every 24 hours and at start “drained” all pins by repeatedly reading from them.

      I’m reasonably sure, this setup is cursed enough to kill an electrical engineer on sight, but it kind of works good-ish enough.

    I regularly recommend configurations to peers that are arguably impossible for normal humans. (Not on purpose! Sorry Dave!)

    I love to run stuff on Raspberry Pi, and I fear no gcc compile flag. (Ok. That’s a bold faced lie, even I fear a couple of them.) So I frequently forget the bullshit I had to do to get something weird running on a random Pi.

    I ran chmod 777 /dev/uinput so AntiMicroX worked on Wayland. The PC was intented to be used as an HTPC. A Dualshock 3 would be the remote and KDE Plasma Bigscreen would be used to launch Linux native apps ie. Firefox and Android apps via Waydroid, hence the Wayland requirement. AntiMicroX would bind gamepad inputs to arrow keys, enter, ESC, volume up/down, mouse navigation, left/right click etc. The whole setup was duct tape, user unfriendly and it ultimately did not solve the problem that sent me down this rabbit hole: Internet was unstable even with an ethernet cable so it had no advantage over the crappy Android TV stick that had trouble streaming anything but Chromecast. A close contender is having to disable Internet when launching a specific online only game otherwise performance halves. There is also a guide I uploaded to Reddit that describes how to import ringtones from Linux to iOS that has 8 steps and involves rebooting your phone. And another guide to run 2 games at once and stream one of thrm while playing the other locally.

    I have a problem with half working duct tape solıtions.

    Prior to switching (upgrading?) to Wayland, Debian KDE crashed under X11 regularly when waking from hibernation and the taskbar would disappear. Restarting the plasma shell made it operable again, so I created an alias and regularly rebooted the DE shell 2-3x a day:

    alias damnTaskbar='killall plasmashell ; kstart plasmashell &'

      # for plasma desktop
alias kplasma='plasmashell --replace & disown'

# when kwin crashes or acts weird
alias kbug='if [ "${XDG_SESSION_TYPE}" = "x11" ]; then kwin_x11 --replace & disown; else kwin_wayland --replace & disown; fi'

    Possibly my light/dark mode scripts. They change my Plasma theme, which is honestly most of the job, but also set the matching GTK theme, set the new theme in running Konsole sessions, do a bunch of manual sed edits on conf files for applications that don’t follow system theming, finally restarting plasmashell to clean up the occasional edge case where a tray icon is supposed to follow the theme but doesn’t.

    I have an old laptop running some basic services.

    I have taken it apart before to replace the hard drive with an SSD, but I never replaced the dead CMOS battery because you have to literally completely disassemble it to get at the battery.

    So I have a cronjob that runs on startup to change the system clock to the right time-zone.

    It just felt simpler than completely disassembling a hard-to-take-apart laptop.

      Debian (and Ubuntu) has the package “fake-hwclock”. I’m sure other distros do too.

      Periodically saves the time info to disk and resets the clock with it on boot.

    Had a Centos VM that kept slipping time. Every week it would loose about 30min. No amount of NTP syncing got the time correct until manual intervention.
    Msp couldn’t work it out, couldn’t rebuild the server for infrastructure reasons, and only that server had the issue. The other 3 VMs on that host were fine.

    Cron job on one server took it current time, sshed to the dodgy server and configured the correct time.

    Had a zfs array on an adaptec raid card. On reboot the partition table would get trashed and block the zfs pool from coming up, but running fdisk against the disk would recover it from the backup.

    Had a script to run on reboot that just ran “fdisk -l” on every disk, then brought up the zfs pool. Worked great for years until I finally did a kernel upgrade that resolved it.

    I have a folder full of scripts tied to aliases that fix various things when they go wonky, and I’ve long since forgotten what any of them do. I just know if xxx app stops working, I type fix_xxx into the terminal and then it does a bunch of stuff and then it works again lol.

    Also I have a bunch of aliases tied to common tasks, like e1 = reboot, e2 = shutdown etc. I have no idea where that habit came from.

    Edit: ALSO, just the general mish-mash of apps. I won’t have anything to do with Snaps, but the rest of it is an unholy combination of native apps, things from the AUR, flatpaks, Appimages, Docker containers and wine setups, mostly (but not all) in Bottles.
