What hardware does not support Linux?
I never really see hardware lacking Linux support mentioned, which got me caught by surprise when a computer with a Broadcom network card couldn't use the card. What other hardware don't work with Linux?
You're viewing a single thread.
Broadcom, as you've discovered. That's the one brand that I've always had trouble with; they go out of their way to be closed source: never publishing specs, never responding to developers. They're horrible to the point where I will not buy any product that uses Broadcom chips. Which used to be a PITA because they were also common.
Fingerprint readers, in general, also widely seem to be poorly supported.
One of my computers has a MediaTek wireless chip where WiFi isn't supported but Bluetooth does.
A lot of people have problems with NVidia cards; I've not had trouble with either AMD or Intel GPUs (although, I think all Intel GPUs are CPU integrated?).
Multifunction printers are still iffy, and even just plain printers can give grief; I've come to believe that this is simply because CUPS is ancient and due for a completely new, modern printing service. It's an awful piece of software to have to work with.
Brother printers have a good reputation in the linux world. Not sure what the current status is... My printer is over 15 yrs old
I bought a new one recently. Apparently they're doing a subscription thing now, so look closely at which model you're buying. But other than that, it works just the same as my old one.
My experience with Brother was also good, until it got tipped during a move and came out simply covered in toner. We don't really need a new printer, but I'd buy another Brother LaserJet in a heartbeat.
We have a wireless Brother laser MFP from 2-3 years ago that just works. I needed to scan something for the first time a few weeks ago and started to go down to rabbit hole of the official driver package but then I decided to give "scanimage" a try and it just found the scanner.
I'll give that a try. I actually never figured out scanning on linux
I bought a Brother colour laser last year (which on the outside looks identical to the monochrome one I bought 17 years ago that lives with my parents), zero issues, which pretty much has been my experience with printers on linux (also tried a ~5 y/o & 25 y/o HP LaserJet, one being the cheapest thing I've ever used, other being old office equipment, think I tried the Epson ecotank and photo printer my mil has as well)
Fwiw, mine has worked with no issues on any of my Linux PCs.
@9488fcea02a9 @sxan Almost all printers work now, since they have to support IPP Anywhere to be useable by phones
My Canon regularly gives me grief. My Epson Ecotank, OTOH, has been painless.
Intel Arc discrete GPUs released 2022
Hmm, I run an Arc GPU at work without any issues. Just using plain mesa on NixOS. The Intel devs were quite responsive when we ran into issues as well.
Arc support was added after release to Linux Kernel 6.2 and it's steadily improved since. Older Linux distros, or "LTS" oriented distros that favour stability may still not have support for them. I know Unraid was very slow to pick up on it and I had to settle for passing the pcie device through to a VM to get it working. Intel is keen to made these viable though, and I love having the AV1 encoder from my A380.
Ah I see, haven't been on "stable" distros for a long time so I wasn't affected. I've enjoyed the good support and the video stuff is definitely nice. On the AMD side, still no idea how to encode or decode anything on my Framework 16, meanwhile Intel is acing it.
I've run AMD, Intel, and Nvidia on linux and I would say my intel experience was by far the best. I use an a380 in my server for transcoding, and I had an a750 in my desktop but switched to a b580. AMD gets the graphics stuff right, but intel does the graphics and compute right on linux where AMD ROCM is a major pain in the ass. It may not be great if you do tons of gaming, but it works quite well for me.
Cups is so much better then everything printer related that is available for Windows and it works so good that even Apple was not able or willing to create something on their own and are using it their OS on all devices. Yes, the web interface is dated but nearly every Desktop comes with a modern integrated interface for printer setup and configuration. It is ages that I had to use the web interface. Cups comes with a boatload of printer drivers out of the box. And if not then there are often PPD files on the homepage of the printer manufacturer.
Multifunction printers are a special case and if they are supported or not depends either on how the device is build (are the parts addressable Independently as printer, scanner, modem/Fax) or is it all a integrated mashup that needs special software or drivers from the manufacturer. In the first case can the printer part often be used with cups and the scanner with sane. Well in the second case there is not much that Linux developers can do without support and goodwill from the manufacturer.
I have been fine with both Canon and Lexmark and also a Brother unit that someone in my family owns that their new Win11 machine refused to talk to; I opened up my ASUS t-pad with Ubuntu and printed in five seconds.
But yeah CUPS has actually caused many a headache to the point that Iβve disabled it on some units.
CUPs is simply ancient. It's due for an overhaul; I keep expecting someone to come along and Poettering it, only I'd hope without also making it take over cron jobs and logging.
Iβm not Linux-savvy enough to understand everything you said lol. But Iβm glad at least that I donβt have to rely on CUPS I just have two printers with static IPs so itβs easy-breezy George and 'Weezy.
fingerprint readers
i had a microsoft branded reader that had its software discontinued in windows vista. it cant be used with windows anymore.
last i tested on linux it just lights up and works straight away.
I have spent literal hours of my life trying to get the fingerprint reader on a latitude 7400 to work and i just gave up lol. Passwords are underrated anyway.
Fingerprint readers, in general, also widely seem to be poorly supported.
Not sure if it technically counts as fingerprint readers but using my YubiKey Bio daily, for login on my desktop and WebAuthN and... 0 problem.
I think that's because Yubikey handles the fingerprint reader part, not Linux, right? As far as Linux goes, it's a black box security fob - but I might be wrong about that.
Indeed hence my warning. I'm only sharing this alternative because in practice it works and it's secure (AFAIK).
Edit :
black box security fob
IMHO that's a feature, namely I do not want to OS to mess with this specific part of my setup. I do also have NitroKeys and FPGAs to tinker with but that's different. FWIW if there is an OSHW&FLOSS alternative to the YubiKey Bio please do share.
Yeah, I wasn't saying it was bad; I meant only that Linux didn't have to worry about device drivers for it, because the fob handles reading the fingerprint chip.
