The big one seems to be the inability to buy a mainstream device with a Linux distribution preinstalled. The few options I know of are niche devices or sometimes single models usually marketed as dev devices. It is also near impossible to even find something without any os installed. Even manufacturer like Framework doesn't offer Linux preinstalled laptops or even just fully assembled ones but without os.

Lacking third party software and hardware support. This is a very real problem and something that can make Linux unviable for specific use cases but also something that will never resolve without higher adoption in personal computing, my guess is at tenth of marketshare we would start seeing it being treated as a serious option. It is amazing that something like wine exists and how well it works but it still can't do everything and it is worse than native support. Similarly not many people are willing to even consider VMs or dual booting for specific workflows that need Windows.

Fragmentation of distros and ways to do things but with standard recommended beginner distros this seems to me more of a perception then a clear problem for most use cases for majority users who would theoretically migrate.

A fallacy where people value a thing perceived to be free less also seems to play a role along with public perception of Linux and its users. Slogans such as Linux is only free if you don't value your time which is ironically IMO more true of Windows these days with the cost usually part of the price of the device and not really perceived or considered by the average buyer.

This seems similar to the usual jokes about vegans and other ill formed perceptions. My guess is that it is the result of people plain ignoring things that have potentional to be uncomfortable along with those with niche opinions being more likely to have considered them and to have strong reasons to hold them along with wanting to at least tell people what they are.

I am just plain ignoring Mac here to be more concise and because I have zero experience with them.

This isn’t really meant to be a hate post or “linux sucks” kind of thing, in fact I like Linux (EndeavourOS being my distro of choice). This post is more about the little things that nobody really talks about when comparing OS’s, but then you face them and they can be a dealbreaker or a pain in the neck.

This weekend I decided to try running CachyOS in my gaming desktop. For quick context, my desktop is dedicated to gaming, everything else I do on my laptop. The desktop is plugged to a 1080p 60hz monitor and a 4k 120hz TV (hz relevant for later), uses sunshine for streaming, and also Virtual Desktop for my meta quest.

So, I grab the USB and plug it into the PC. Turn it on and here comes the first issue: the background image appears and nothing else.

Well, my first suspicion due to a similar issue I had with ubuntu a decade ago, must be the Nvidia GPU causing issues. Without investigating further, I restarted the PC and used the legacy mode. The resolution was extremely low in my monitor, but it was manageable. Installed the thing and restarted.

Once the PC is back on, the login screen appears. I input the pass, enter and…. Exact same issue. Background image, no UI whatsoever.

I spent an embarrassing amount of time here, investigating the error. Checking the drivers, etc.

But long story short: the actual problem was that my monitor was the second screen, the TV was the primary. The desktop was outputting to both screens. The UI was on the TV.

I curse myself for not remembering that this may have been it, but in my defense:
1- the terminal commands that appear when turning on the OS appeared in my monitor
2- the legacy mode worked on my monitor
3- on windows, the OS is smart enough to figure out which screen is turned on, so I was used to it automatically outputting to the correct screen

Well, once I fixed that, here came the second (small) issue:
Scaling is broken.

Windows used to have this problem but nowadays, when you change screen Windows does a good job scaling things, despite some issues with some apps. At the very least, you won’t get blurry windows.

On KDE… Yeah. Blurry all around. I don’t have a habit of swapping screens mid session, so I could live with it.

Then came the third issue:
KDE is limited by the lower highest possible framerate in both screens. Meaning, on my TV, I was stuck with the 60hz because of my monitor

From what I found out, this is not exclusive to KDE and seems to be a problem with Nvidia. Regardless, for me it was a dealbreaker. In my case, Windows can use the respective framerate of each screen, while Linux can’t.

As I said, this is where I threw the towel and went back to windows. Which is really a pity because I really don’t like where Windows 11 is going, but it’s something I can live with as long it doesn’t get in the way between me and gaming.

Meanwhile Linux, because of these little things, introduced more issues than rewards for my use case, thus why I can’t jump to it on my desktop.

Following this guide (linuxtechi) and got Mint Cinnamon 22.2 (Zara) - yes the iso is verified, created bootable USB with Etcher, and after the screen where I input user details and password, well along the install process, got a fatal error (screenshot) :
Unable to install GRUB in /dev/sda
Executing 'grub-install/dev/sda' failed
This is a fatal error
Here is a screenshot of the GParted, fdisk, df, lsblk and what re-running the install now looks like.

Restarting (after pulling out USB) , instead of going to Windows 10, goes to a black screen that says

This is not a bootable disk. Please insert a bootable floppy and press any key to try again ...
Turn it off, back on with USB, at least I can still boot from there into USB-space mint for now.

I'm guessing this has something to do with some peculiar hardware/BIOS settings than the fault of Mint. Worth mentioning that this is a refurbished 2013 HP box (order excerpt) , with a windows 10 digital key license, and that upon every fresh boot up (first time ever to now) it shows a black-background screen that says

The preboot authentication application cannot be found.
Press any key to attempt boot without authenticating.
so it's very possible something is bork'd from the get go or else it has some very unorthodox settings to begin with.

Can confirm running Mint off the USB is fine. The screencaps are sent from Firefox within, and I'm super happy with how clean everything is. Just not sure what to do now. If it's complicated, I can try sending the box back for refund and try again with another brand new box. But now I'm shy about trying dual boot on my regular desktop.

Questions after looking around for help:

1. am I booting from UEFI or Legacy? I don't know -- how do I check ?
2. Fatal error installation hard stop: is there a way to access a log of what happened ?
3. How do I boot back into Windows 10 for now ? use GParted to delete all the "new" partitions and try booting again?

Edit: gave up . It's now a Mint box. Goodbye Windows you can kiss my dust

Background: I started daily driving Linux (specifically Mint) several months ago and for the most part it's been great. Some weird hiccups occasionally but nothing I can't handle/deal with. When doing my research to set the system up for the first time, I decided to go with 30GB for the / partition and ~220GB for the /home partition (the other half of the drive is for Windows 11 and the various essential tiny partitions). For a while this seemed to be fine, but lately I've been starting to get warnings when performing software updates via the Update Manager that the / partition is running out of space. I think it peaked at maybe 90-95% full a few weeks ago, at which point I started doing some research and cleaning up a bit (apt autoremove, deleting old logs and kernels, etc). I was able to claw back ~4GB and kick the can down the road, but now the warnings have returned and I'd like to handle this properly. I'm working from the assumption that I simply made the / partition too small and intend to double it by giving it some of the Windows space.

My question: How do I know if this is expected or if I've been doing something wrong? Is 30GB indeed too small on modern Mint, or should that have been enough? I know it partially depends on what all I actually do with the computer, but I really don't have very many applications installed (aside from defaults of course) and only four of them are Flatpaks, which I read tend to be larger. If it helps, the Disk Usage Analyzer reports that within /, /usr is taking up 13.2GB (55%), /var accounts for 9.1GB (38%), /opt is 1GB (4%), and everything else is <1% each.

Thanks in advance!

Pretty much what the title says - I'm building out a smallish compute cluster and hoping to set up some centralised storage that won't be a bottleneck, but I'm very much not a networking specialist. Most of the load will be random reads from compute nodes pulling in the bits of various datasets they need to work on.

Is it plausible to throw a 100GbE ConnectX-5 card and 256GB RAM into a consumer AM5 machine, format everything in ZFS, and set up a network share with KSMBD? My understanding is that I want to ensure everything's using mirroring rather than worrying about RAIDZ parity if I'm optimising for speed, which is fine, and I know that I'll only get full throughput as far as things can be cached in RAM - but is it reasonable to expect ZFS ARC to do that caching for me? Dare I hope that the SMB driver will just work if I drop it in there between the filesystem and the NIC? Or have I crossed the line into enterprisey-enough requirements that it's going to be an uphill battle to get this working anywhere near line speed?
