You don't need to use big-O. You can calculate the full complexity in algebraic notation. It's just a lot more work as you don't get to discard terms.

I think I remember running into that as well but for whatever reason I couldn't get accelerated-x working with the opengl libraries I was using for school. Likely the issue was just a lack of understanding on my part as I don't think I had a good grasp of the Linux library loader until well after I graduated.

I've had a system in the late 90s with a 3dfx voodoo card. Also had a laptop with a SIS card from the early 2000 era.

The voodoo card was THE card to have it it's day (mine was an older second hand system though). The SIS card... for some reason they decided that standard VESA mode probing wasn't a thing they supported and would hardware crash when that API was used. I eventually got it working in Linux after patching xfree86 to not attempt probing when loading the VESA driver.

You may want to try hotter too if you haven't yet. Printing faster can sometimes require a bit of extra heat and too low can cause a different kind of stringing.

QEMU supports either spice, vnc or sdl graphics output. If you want to copy/paste you need to use spice and install the spice agent on the VM.

If you want an automated system that can protect against ransomware your backups need to be hosted in some way where the backup server has control of the retention and not the client (NAS, local disk, etc are not sufficient). If your NAS supports automated snapshots that can't be deleted by the backup user it can mostly fill this gap but may need to be checked for how it handles snapshots when the disk fills.

For self-hosted solutions I've used BURP, Amanda, and Borg backup in the past but have switched to Proxmox backup server as my VMs all run in Proxmox. You still need to consider full disaster recovery scenarios where both your primary and backup system fail. For this PBS sports both tape and remote server replication.

There are also many cloud solutions that do this automatically. For cloud I would always use them in tandem with some kind of local backup.

For all of these they should have an admin account that has strong protection and doesn't share credentials with any of the primary systems.

My steam deck also unlinks family libraries with almost every os update. It might be an issue of overzealous hardware validation but it could also just be a bug.

It's very likely that your disk is failing.

dd if=/path/to/file.mkv of=/new/file/path.mkv conv=noerror,sync bs=4k

Should give you a file with just the damaged bits missing.

The underutilized ~~post~~ pre increment operator.

Are they on a local disk? Thunar doesn't render any thumbnails for remote storage by default.

You can still enter audit mode and change some registry settings to switch to a local account. Last time I did an 11 install on a device with Wi-Fi it also let me create a local account after trying to continue with a blank password a few times.

If it isn't showing up in lspci then it isn't currently attached to a PCI port. lspci will show all devices with or without a driver, known and unknown. You can try lsusb to see if it is attached internally to USB (very uncommon). It might also have a firmware level power saving disconnect feature that needs to be either disabled or managed by the OS in some way. It might also be showing up as a different device than you expect (also very uncommon) most cards will show as either Ethernet controller: or Network controller:.

Make and model of the laptop and any identification details from the ethernet device under windows would be helpful for diagnosis.
