> This is a bit like asking "who still uses keyboard shortcuts?" No, it was a good-faith question of who finds it useful (for what type of work) these days. I think it's a fair question since every other manufacturer has settled on trackpads. As context, I added that I, personally, find it ruins my screen on an otherwise good laptop. Why the rant about keyboard shortcuts? The only answer you gave to my question was e…

You are right, my rant about keyboard shortcuts was not really related to your question and did not answer it. So with apologies for my rather tangential analogy, let me explain how I got there. I recently read a ThinkPad review where the author said something like "Why does Lenovo insist in keeping this stupid red nubbin when nobody uses it?" In other words, "I don't use it, so I can't imagine that anyone else would…

Thank you for the follow-up! Very thorough. Sorry if I was being rude.

I do use the mouse buttons on occasion. I can't actually remember the last time I used the trackpoint. I did in some cases, but the annoyance over the dirty screen became too much and it had to go. ;)

Re. lid pressure, that will certainly make it worse, but the T460s I use at home rarely goes outdoors, so I don't think that's the cause. I see dirt build-up on the screen even now that the trackpoint is below the keys, so there's probably finger oils rubbing off the keys as well. Oh, and maybe using the rubber a lot will flatten it so rubbing is less of a problem.

> My suggestion there would perhaps be along these lines

Thanks. I still find it amusing that politness and humbleness is not the implied default, but something that needs to be made explicit every time. I should have taken the time to write something longer. :\ Next time.

To prevent overheating on my X1 ThinkPad under Fedora I set the CPU governor to the power safe mode. As an added benefit it makes the laptop almost silent even when using all the cores/threads to compile huge C++ code base that may the memory usage towards 32 GB. Surely it compiles slower, but the slowdown is less than 25%

Can you elaborate on how to set the CPU on that mode? Is a command or BIOS setting? I would like to do the same on Ubuntu.

The easy way in Fedora is using `tuned-adm`.

```

$ tuned-adm active ...

$ tuned-adm list ...

$ tuned-adm recommend ...

$ tuned-adm profile powersave

```

I'm a random stranger on the internet, so with no intent on telling you how to live or interact :), My own limited biased subjective 0.0005 cents: 1. Original question: "Who's still using this?" is direct and to the point; I grok it. But note that some people in many contexts may interpret it... aggressive. Human mind fills in detail in blunt / short sentences. Politeness in some cases is filling in those blanks pre-…

Thank you. I see Stratoscope responded as well, so I'll keep this short. (again :) Re-read the post. The original conclusion was: > The TrackPoint may be something like this. Those of us who insist on it may be small in number. But if it is ever removed, then the one reason why we will only buy ThinkPads is gone. We may as well get a Dell or an HP or a Mac M1 or whatever. It says nothing of who "those of us" are (the…

Right.

I think a few posts went on to eventually answer factually what we love about trackpoint - keeping hands on home row, preciseness, speed, high skill ceiling, etc.

But I also think the keyboard shortcut analogy, while indeed not talking about TrackPoint itself, is actually the most useful post for the goal of understanding it: One may never agree about usefulness of TrackPoint, but that analogy helps with understanding that "There's a small minority of power users for whom this is a force multiplier and who feel very strongly about the optimization it allows them" :)

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…

Note that the newer P1/X1E Gen 4 have a much upgraded cooling system if you configure it with an Nvidia 3070 or higher. I don't experience any heat issues, even during heavy compilation and integration test work. The exception is if I run games at 4k resolution on an external monitor, then the GPU appears to overheat, resulting in the screen randomly going black.

What's your battery life like?

According to the official documentation [1], the 13" M1 MacBook Pro also has this limitation: > If you're using a Mac with the M1 chip: > > On iMac, Mac mini, MacBook Air, and 13-inch MacBook Pro, you can connect one external display using either of the Thunderbolt / USB 4 ports. [1] - https://support.apple.com/en-afri/HT202351

Well, the 13” M1 MacBook Pro is basically the Air with a fan and more ports?

Yep, though that's really more of a question of chip: the M1 only supports two displays, for the laptop that includes the internal one (the Mini only supports two displays, and one only 4K via HDMI).

We use this exact same laptop at Red Hat, and meh! I like the laptop sometimes, but I've actually had plenty of times where it's more of a pain. For example, I run multiple 4k displays on my desktop, and using the Lenovo thunderbolt docking station with multiple 4k displays does not work. two 1440p displays are fine, but not two 4k UHD displays. Another issue Iv'e seen is the laptop simply reboots mysteriously, presu…

Given that IBM has transitioned to MacBooks for corporate use, have at least some Red Hat developers moved to MacBooks as well? On the PC front, do you find that other workstations (Precision, Elitebooks) are better supported with regards to Linux and associated peripherals?

> Given that IBM has transitioned to MacBooks for corporate use, have at least some Red Hat developers moved to MacBooks as well?

Seems unlikely as that'd imply running the OS they're making in a VM: the M1s only officially support macOS, and Asahi only just released their first alpha a pair of months back, with a lot of hardware not working yet. There's also a bunch of software which is not compatible with 16K pages, which asahi uses.

and the lazy way to do this is via "panel" apps (on Genome KDE whatever). I prefer this way since it helps me switch between different modes (such as if I want to do something resource intensive).

I've been holding off on purchasing a new Lenovo laptop. Shortly Lenovo will start shipping latops with the new generation AMD Ryzen mobile chips that have RDNA 2 GPUs. [0][1] This is a real game changer. The amount of power and open source VULKAN friendliness is going to be incredible. I look forward to being able to do container work, and emulate Gamecube games all on a single Linux machine. [0] https://www.aroged.…

> The novelty (T14s) features ... USB-C 4.0 Gen 3 This one could be a better value compare to the Intel one, if it provides support for Thunderbolt 3 eGPUs. One downside I can think of is that T14s usually only comes with soldered on RAMs, no DIMM slot, meaning it's less upgradable (say to 64G of RAM). That's why I'm waiting for a new AMD T14 which should come with a DIMM slot and hopefully USB4. And if Lenovo failed…

Oops: should have read the news before commenting. The new T14 AMD might not come with DIMM slot. See https://www.notebookcheck.net/Lenovo-ThinkPad-T14-G3-ThinkPa...

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 goo…

> consumes 3.9w is this figure taken from software (powertop) or from a wall power-meter (i.e. including the psu)?

It's measured from the battery when unplugged: /sys/class/power_supply/BAT0/power_now

Can you share your script for toggling the video card?

No elaborate script is needed these days, the kernel's runtime power management suspends the card automatically as long as /sys/bus/pci/devices/…/power/control is "auto" and the device isn't being used (the nvidia/nouveau module is unloaded). Documentation for the nvidia module claims [0] runtime pm is supported even when the module _is_ loaded for GPUs since Turing, but I haven't been able to test that (mine is olde…

That. I used to use bumblebee, but with recent NVidia drivers it's automatic.

That said, if I want to start a process with using the NVidia driver and card I use this script.

  #!/bin/bash
  __NV_PRIME_RENDER_OFFLOAD=1 \
  __GLX_VENDOR_LIBRARY_NAME=nvidia \
  __VK_LAYER_NV_optimus=NVIDIA_only \
