I own Thinkpad X1 extreme, that I bought with my own money, and chose as working laptop Thinkpad Carbon. Both are not working well with linux. 1. Carbon, due to it's intel chip, can not drive 4K and 2K external monitors via thunderbolt adapter. 2. I need to authorize dock (Lenovo's thunderbolt dock) after every reboot. 3. The screen tearing sucks. 4. I need to have pulse audio volume control window opened all the time, otherwise the laptop loses my external sound card after first call via browser, and I need to turn it off/on. On my own laptop, where I installed Ubuntu, I can boot only into 5.8.0.43 kernel (the one which I initially installed). All others, that I've got via apt-get update stuck with blinking cursor at last step of boot, and it's well known problem. The longer I'm trying to love linux for work os, the more I realize that only tool that I truly want from linux is i3. For the rest I'm happily using WSL2 on my home, and don't have choice with work. So on next hardware refresh date I think I'll choose Mac. The supplied by job laptop config is also more performant than carbon. So, hope, I'll be able to use my monitors in native res, and not put 2K into 1920x1020 mode

  Why does it have a ‘tearfree’ ‘false’ option?

  However, TearFree does murder performance and lead to some horrible screen lag at times, and as an extra bonus AccelMethod sna is still crashy years after being introduced :( edit: there's also the modesetting driver + a reasonable compositor, but this can come with it's own set of bugs and issues in my experience.

    I've been interested in recording music using free software on Linux. The exchange above is similar to the cycle I've been in... encountering problems, finding magical incantations that fix things in some ways but often involve some sort of tradeoff, and making gradual progress toward being as productive as I am using Apple's Logic. But I've been doing this three steps forward, two steps back routine for like three years now. I have most things working but it has really taken the full force of my frustration with Apple to keep returning to it and making progress.

      It's exactly why I have mac laptops for work and personal use, although I also have a full time linux desktop (and also a windows one for gaming. still no real alternative there!). I'm an easily frustrated person and I end up with enough pain points on linux for both work and personal use that I've never managed to make the switch full time.

Curious. If you had to buy tomorrow, what would you do? Given that M1 Pro won't be out till end of 21(?) and despite that, current Pros don't seem to come with a reduced price.

  I have a 13” M1 pro, it’s easily the best computer I’ve owned (and I have a Ryzen 3600/Vega 10 desktop with 128GB of RAM that runs KDE Plasma very well, but there’s still no competition)

  I haven't done my research recently. Thinkpad works fine with Windows, so, most likely, it'd be last gen Mac/Thinkpad Extreme or something in that league. I had hopes that Microsoft will evolve Surface Books to normal processors, but it seems like the line is dying.

  I wouldn't be surprised if it was a thunderbolt linux issue. The dell "docking station" usb-c hubs don't really work well with anything else than dell windows machines. Same with some lenovo bluetooth mice. I do remember however that contrary to macos my 2012 macbook air could drive higher resolution external monitors when running linux. So I'd put this into the Thunderbolt is a hackjob on linux box.

    I think this might be issue with given laptop. Some non-apple laptops sometimes reduce badwidth of thunderbold 3 (e.g. in mine t490s the bandwidth is halved, just because - this is hardware, not linux).

If you're still facing this, there is UI for remembering the authorization https://christian.kellner.me/2018/04/23/the-state-of-thunderbolt-3-in-fedora-28/ https://christian.kellner.me/2018/04/23/the-state-of-thunder... I'm on a AMD device right now so I can't test it myself, just sharing the link in case its useful :)

I was having huge flaky thunderbolt problems on my Linux T490 - even updating the laptop firmware didn't fix it despite Lenovo changelogs indicating a bunch of thunderbolt dock bugs fixed. Then I swapped the Lenovo thunderbolt dock with another one at work and everything just worked fine. I run 3 monitors (2 external 2560x1440) at once, but no 4k. Maybe it was dock firmware versions - the Lenovo dock updater software was Windows only, so I had never tried it.

  sudo fwupdmgr update was finding updates for thunderbolt dock on linux

  I was trying to make the Mac to Linux switch just like the author, mostly due to excitement around sway (wayland). But it was awful, none of the basic things I wanted to do seemed doable...I would research solutions and they wouldn’t work. So I tried switching to i3 in the hopes of at least having a more established ecosystem to rely on. But similar story. Half-baked (or sometimes, overcooked) support, configs that we’re supposed to swap eg CapsLock with Escape not working as described or losing their effect after sleep, impossible to get my multi monitor high DPI setup to work without coloration or resolution issues, futzing around with sound and not able to get it working as hoped just like the last time I tried to do this in 2008...you know, all the things you want before you start doing actual work, but none of them function properly OOTB or, often, even after reading extensive documentation and advice. I wish I could use i3, but my BetterTouchTool configuration gives me something that is close enough. I might still try FreeBSD, but I totally feel twice-burned by Linux at this point.

    > I was trying to make the Mac to Linux switch just like the author I've tried a couple of times, but finally decided what's the point. Linux is amazing on all the servers I run and manage. It's lightweight, supported well, and does a great job. I also rarely have to tinker with it. For servers, it really does just work. On the PC side not so much. I used to run linux in various flavors on the desktop side for years. It provided more power than windows IMO. Then OS X came out with actual unix underpinnings, a functional media system (UI, audio, video), and fully supported creative apps like Ps, MS Office, and later LR. Against my better judgement I tried a final time move to desktop linux a couple of years ago, but multi-monitor mixes of hi and low dpi were just unworkable. I actually posted a question (it may have been here on HN - can't remember), and one of the responses was 'no one needs HiDPI screens'. Got it.
