I have recently acquired a Lenovo Thinkpad P14s Gen 5. As of the time of writing
|
||||
-- summer of '24 -- these machines are brand new, and so is their architecture:
|
||||
Intel Core Ultra (Meteor Lake) with a dedicated NVIDIA GPU. Here I report my
|
||||
experience with running Linux with the [KDE Plasma][] desktop on this machine.
|
||||
|
||||
My previous daily driver was a T480s (see my old blog post over at [xltoolbox.net][]
|
||||
for a report). I also administer two different X1 Carbons (5th generation and
|
||||
9th generation), however, I don't use these very often myself.
|
||||
|
||||
Here are the specs (the 1 TB SSD has been swapped for a Samsung 990 PRO with 2 TB).

## Difficulties and finally success with installing Linux
|
||||
|
||||
At first, I was totally unable to install [KDE neon][], my preferred Linux distribution,
|
||||
on this system. I freaked out. (I don't care if it's officially a 'distribution' or not.)
|
||||
The live CD just would not boot. It did work in safe graphics mode, but when I installed
|
||||
the system onto the laptop, I was once again unable to boot into Plasma.
|
||||
(I already posted in the [KDE forum][] about this).
|
||||
|
||||
At some point it occurred to me that I may need to try a distribution, so I tried [Fedora][]
|
||||
-- and it worked!! In order to boot the live CD, I also had to choose basic graphics mode
|
||||
just like with KDE neon (which is Ubuntu under the hood). Once I had the live desktop up
|
||||
and running, I could enable the NVIDIA repositories, so that the NVIDIA drivers were
|
||||
included during system installation. Luckily, the Fedora Project provides a [KDE spin][]
|
||||
so that I could continue to use my favorite desktop environment.
|
||||
|
||||
## Hardware
|
||||
|
||||
Except for the initial difficulties getting this system with a dedicated NVIDIA GPU
|
||||
to run Linux, everything else just works out of the box. Nice! :-)
|
||||
|
||||
The **trackpoint** works as usual. This is really the main reason why I keep buying
|
||||
Thinkpads. A laptop without trackpoint is a no-go for me. In fact, I did consider buying
|
||||
a MacBook Pro, but the absence of a trackpoint and the uncertainty whether I could do
|
||||
my beloved Linux foo with MacOS made me stick with a Thinkpad.
|
||||
|
||||
The **fingerprint scanner** is integrated into the power button. While not essential, it's
|
||||
a nice gimmick and KDE Plasma provides a pretty UI to set it up. Currently, logging
|
||||
into the system after booting is not (yet) supported, but unlocking (e.g., after resume
|
||||
from sleep) works very well.
|
||||
|
||||
The 3k **screen** is really good, it's very bright and super crisp. At 100%, the
|
||||
user interface is quite tiny. Luckily, with Wayland, fractional scaling is now
|
||||
easy to accomplish and reliable. With a scale factor of 1.2 (120%), I am very happy
|
||||
with my P14s' display. Interestingly though, the corners are rounded, even though
|
||||
the laptop frame has sharp corners. I tend to think: If you have enough time wondering
|
||||
about something like this, it's probably time to take a break and do something else
|
||||
for a while.
|
||||
|
||||
Unfortunately, the **keyboard** is the worst that I have ever had in any Thinkpad.
|
||||
It feels like typing on jelly. Luckily, for most of the heavy-duty work, I connect
|
||||
the laptop to a Thunderbolt dock with a proper mechanical keyboard attached.
|
||||
I wonder why Lenovo does not equip this machine with the same keyboard as in the
|
||||
other models -- given the price tag of this machine, the extra bucks surely cannot
|
||||
make such a big difference?
|
||||
|
||||
**Camera**, mike, and speakers just work. No problem running Zoom. I have not yet
|
||||
tried out Teams.
|
||||
|
||||
## Form factor and weight
|
||||
|
||||
The P14s is somewhat bigger than the old T480s and certainly somewhat heavier.
|
||||
Before deciding on the purchase, I carefully thought about my use cases and decided
|
||||
that I can live with an extra 200-300 grams that I mostly only carry onto and
|
||||
off from the commute train, as well as on my bicycle's rack. Therefore, I made a
|
||||
decision for the extra performance (with dedicated GPU, which the alternative
|
||||
models, i.e. X1 Carbons or T14s's do not offer).)
|
||||
|
||||
Lenovo [says][p14s-weight] the P14s starts at 1.6 kg, which compares to a MacBook Pro's
|
||||
nominal weight. On our kitchen scale, my P14s weighs 1.74 kg.
|
||||
|
||||
In real life, the laptop's body is somewhat bigger than the actual casing, because
|
||||
it has a very long "foot" underneath it. This ensures proper ventilation, because
|
||||
the two fans blow out the warm air underneath the laptop. While this "foot" makes
|
||||
the P14s rather thick, it turns out that this also provides a good grip when pulling
|
||||
it ouf of a bag or carrying it around.
|
||||
|
||||
I have yet to come to terms with the new camera casing that all new Thinkpads
|
||||
seem to have nowadays.

||||

|
||||
|
||||
## Performance
|
||||
|
||||
Compared to the old T480s, the performance gain of the Intel Core Ultra and the
|
||||
dedicated NVIDIA GPU is very noticeable. Whether I compile R packages or analyze
|
||||
clinical data with ~80k subjects in [RStudio][], develop RAW images in [Darktable][],
|
||||
or work with Office in a VirtualBox-hosted Windows machine, everything is very
|
||||
snappy. For instance, a typical RAW image is now processed in under 1 second, as
|
||||
opposed to ~10 seconds on the T480s.
|
||||
|
||||
The machine wakes from sleep (suspend to RAM) extremely quickly, I guess this is due to
|
||||
[novel suspend mechanisms][s3]? On the other hand, boot times are rather slow
|
||||
(34-40s on AC power, T480s on battery 31 s!!).
|
||||
|
||||
## Fan
|
||||
|
||||
The fans spin up quickly, but the noise is not unpleasant. Maybe I can tweak the
|
||||
fan control in order to have them spin up a little more lazily. But when I had both
|
||||
my old laptop and the new one side by side, I realized that the T480s' fan noise
|
||||
drowns the P14s' fan noise. Notably, the P14s was running on AC power, while the
|
||||
T480s ran on battery. In fact, even the T480s with built-in graphics had its fan
|
||||
running most of the time when I was working with it (academic work, researching,
|
||||
writing, data analysis etc.).
|
||||
|
||||
## Energy consumption
|
||||
|
||||
The P14s' battery has much more capacity than the T480s' one, 75 Wh vs. 42 Wh.
|
||||
However, with my normal work load, the battery drains rather quickly. The
|
||||
following screenshot shows the charge level over time as I sat outside,
|
||||
editing a manuscript with Word running in a virtual machine (VirtualBox
|
||||
with Windows 11 guest) and doing some internet research in a browser. The
|
||||
screen brightness was set to 100%. After some 3.5 hours, it's time for a
|
||||
break...
|
||||
|
||||

|
||||
|
||||
## Making the switch from Ubuntu to Fedora
|
||||
|
||||
When I downloaded the Fedora [KDE spin][], I was admittedly a bit anxious.
|
||||
I had been working with Ubuntu and KDE neon, which is based on Ubuntu,
|
||||
for many years, and I wondered if Fedora would be very different.
|
||||
|
||||
It's not.
|
||||
|
||||
The three things that are really different from my perspective:
|
||||
|
||||
- To install something on the command line, use `dnf` rather than `apt`:
|
||||
|
||||
```bash
|
||||
sudo dnf install good-stuff
|
||||
```
|
||||
|
||||
- Removable disks (USB drives) are mounted on `/run/media/<USER>` rather
|
||||
than `/media/<USER>`.
|
||||
- More up-to-date kernel and software
|
||||
|
||||
## Conclusion
|
||||
|
||||
All in all, I am quite happy with the P14s. In the past couple of weeks, it has
|
||||
already proven to be a reliable work horse, and this is what I need. The
|
||||
keyboard really should be better, but hey, life is not perfect, is it?
