By not using Grub you lose the ability to fallback on a safe kernel. That may be quite dangerous depending on how reliable kernel update is for you. I have been saved by kernel fallbacks before. Double that for laptops whose ACPI drivers randomly break from version to version, as evidenced by your note on 5.17.x kernels. Regardless I sympathize, as I recently had a good deal of trouble updating from BIOS to UEFI. The…

This got me looking around at how one would load a luks or dm-crypt encrypted drive from efi without grub. I didn't find anything solid but I've used initram shims for stuff like that before so that might be an approach but at that point you might as well use grub which has some nice features built-in. I guess I'm really curious what there is to gain by bypassing grub if anything?

I don't use GRUB on any of my systems anymore, here's a couple loose answers to your questions.

> This got me looking around at how one would load a luks or dm-crypt encrypted drive from efi without grub.

systemd-boot lets you define an encrypted drive at installation, which is what I do for my LUKS devices. Whole thing works pretty flawlessly, in my experience.

> I guess I'm really curious what there is to gain by bypassing grub if anything?

I mean, you're not "bypassing" anything; Linux has molecularity at it's core, it's perfectly normal to swap out it's surrounding components to personalize your system. Personally, I pass on GRUB because systemd-boot is fast. Booting with GRUB takes 10-45 seconds depending on your hardware and encryption setup: I've never seen systemd-boot take longer than 15. If you're not dual-booting or doing any fancy baremetal stuff, I think most people would be perfectly happy with it. GRUB certainly still has it's place though, and I'm glad it exists.

If you've ever taken apart a ThinkPad, you would notice that inside is a metal frame to support the entire laptop body. It's not plastic. Plus, this ThinkPad (and the newer ThinkPads in general) have a metal exterior

All plastic laptop bodies have a metal frame which tells you how much they have faith in their body construction.

By that logic, civil engineers show how little faith they have in their buildings by having a reinforced concrete support and glass/steel frames around them

> and most importantly: do NOT opt for the 4k screen Good advice for any laptop purchase. You will burn through battery driving that and the pixel density is much higher than necessary. Yes, 1920x1080/1200 is slightly too low when it comes to pixel density at 15", but it's still very reasonable and with decent eyesight you won't have to worry about any of the mess of DPI scaling.

> > and most importantly: do NOT opt for the 4k screen > Good advice for any laptop purchase. You will burn through battery driving that and the pixel density is much higher than necessary. Hard disagree. I use my thinkpads on AC most of the time, at home. The crisp fonts in a terminal is a game changer. That has spoiled me: the bare minimum I can work with now is 2k. Likewise for OLED: except the X1 nano which I use…

2K is only a few more pixels than 1920 x 1080 ?

I find the sweet spot minimum for my 27" desktop monitors to be 1440P. Anything that and above looks great.

I don't want to have to keep track of charging yet another device, esp one as important and frequently used as headphones. Heck, some days I forget to plug in my phone to charge let alone headphones. Not worth the headache esp when there is another version of the device available with "infinite battery life".

my wireless headset can be used while charging. not really a headache. at worst, my wireless headset just becomes wired for the time period that i am using it while charging.

I have wireless headphones. They were cheaper than AirPods (they're Jabra) and have pretty good sound. They're full-size, not earbuds. The battery lasts for a couple days of fairly heavy use, and they degrade to... wired headphones, essentially, since I can use them while they're charging. Also they have a 3.5mm jack if I want to use that. And they've got a microphone, so I can walk around while on calls. Best of bot…

same. mine are HyperX Cloud Stingers for work, and they are fantastic. Range is so-so, but I believe that is due to it being plugged into a docking station.

This is one of the primary reasons I can't even consider moving away from an M1 Mac. I used to love ThinkPads but not being able to use the machine for 10+ hours without charger is a dealbreaker in 2022.

Yea I find them a huge PIA for anything other than gym sessions or running. For that, however, they are amazing.

Then again the battery has just died in one of my wireless headphones (luckily not the primary) which means I can now only exercise with one side. Not a crappy brand either. I have wired headphones going on 10+ years that work flawlessly.

Generally great machines for Linux. Just a PSA from a X1E gen2 owner: Do NOT get the NVidia GPU, do NOT get the fastest CPU and most importantly: do NOT opt for the 4k screen. With 1080p and Intel GPU it is a good, even great laptop with ok battery life (if you can look over the touchpad). Wonderful keyboard, good Linux support (even fingerprint reader works). But just as with the last Intel macbook, the GPU, 10th ge…

Hmm... I have the model with the NVidia GPU. By default I have it turned off (using no extra power) and I have a simple script that I use to turn it on when I want to.

ThinkFan works well to control the fans too.

Lastly I found that the SD card reader prevented the CPU package from entering C10.

With all that I find that in idle mode my laptop (X1E Gen2, almost identical to P1 Gen2) consumes 3.9w, which is pretty good. The fan only turns on when I compile something large or do something with the NVidia card.

> We don't think an aluminium bike is better than a carbon fibre bike Depends on how you define better. Carbon bikes are prone to catastrophic failure, and if you fall often are a bad idea. Of course, you might just say "just don't fall".

Out of curiosity, do you have any sources with actual evidence that carbon fiber is prone to catastrophic failure in bike frames/components, particularly compared to aluminum? From my (rather limited) research, there seems to be plenty of speculation and anecdotes online about the fragility of CF, but not much actual evidence of rates of catastrophic failure. My impression (not based on expertise or much evidence) is…

> Now that use of the material, once reserved for high-end bikes, has become widespread in the bike industry, reports of accidents and mysterious failures are on the rise.

> Reed and other experts in carbon fiber agree that any material can fail. Wrecks happen from faulty aluminum, steel, and even rock-hard titanium. The difference with carbon fiber is that it can be difficult to detect signs of damage that might signal imminent failure. Cracks and dents in other materials are typically easy to see, but fissures in carbon fiber often hide beneath the paint. What’s worse is that when carbon fiber fails, it fails spectacularly. While other materials might simply buckle or bend, carbon fiber can shatter into pieces, sending riders flying into the road or trail. And this kind of catastrophic destruction can happen to any part of a bike made with the material.

> “It’s completely reasonable for someone who wants a lightweight bike to look at carbon fiber, but they need to understand the risks,” Elrath says. “Absolutely this is getting ignored.”

https://www.outsideonline.com/outdoor-gear/bikes-and-biking/...

There are plenty of videos from competitions where the carbon suddenly fails. I've never seen that with aluminum bikes. Last three accidents from 4:15:

https://www.youtube.com/watch?v=kpeTiF_Tm04

But going back, if one is not racing, is it really worth the extra risk for minor performance improvements? Some say that after any serious fall/crash a carbon frame/component should be replaced because it's difficult to assess if it was damaged or not. How many can afford that?

Don't use Grub or any bootloader if you can avoid it. I haven't used Grub in 10 years. Load Linux directly as an EFI executable via the EFISTUB approach. You almost certainly only need to run two or three efibootmgr commands to accomplish this.

Then you should buy a laptop that ships with Linux and has official support from the vendor. Like the Dell XPS Developer edition, or anything from System76.
