that could be a GNU Linux Lenovo floating inside the ISS:

  • “Radiation disrupting electronics, wild temperature swings damaging circuit boards, no communications for hours, days, or even weeks at a time.”
  • “How do you build computers and software systems for such demanding conditions?”
  • “Let’s take a look at who is already using Linux in space, what they had to do in order to build their systems on Linux, and how you can get involved in helping open source software destined for space.”

GNU Linux hardware reviews - something between tablet and notebook: the Lenovo Ideapad MIIX 510 12ISK - Can it Debian? - yes it can (Debian 11 out of the box Debian 10 rfkill reports hardblocked wlan)

Lenovo Ideapad: What is it and can it run Debian?

hint: it’s also not mine.

The Lenovo Ideapad is a “notebook-tablet” (a very slim notebook that pretends to be a tablet (it has a touch screen!) 🙂

can it Debian?

Yes it can pretty fast actually.

What is not working (yet) are the front- and back-webcams (tried with cheese, can not find any cams)

the specs:

<span style="color: #00ffff;">/scripts/bench/<a href="https://dwaves.de/scripts/bench/bench_harddisk.sh">bench_harddisk.sh</a>; # <a href="https://dwaves.de/scripts/bench/bench_harddisk.sh">https://dwaves.de/scripts/bench/bench_harddisk.sh</a></span>
=== harddisk sequential write and read bench v1 ===
starting test on the device that holds the current directory the user is in
no need to run it as root

========== writing 3GB of zeroes ==========
0+1 records in
0+1 records out
2147479552 bytes (2.1 GB, 2.0 GiB) copied, 14.152 s, <span style="color: #ffff00;">152 MB/s</span>

real    0m14.163s
user    0m0.000s
sys 0m5.685s
========== reading 6GB of zeroes ==========

0+1 records out
2147479552 bytes (2.1 GB, 2.0 GiB) copied, 3.407 s, <span style="color: #ffff00;">630 MB/s</span>

real    0m3.434s
user    0m0.000s
sys 0m1.270s
========== tidy up remove testfile ==========

how to get started:

what is good:

  • the speed (i5 CPU & NVMe (!) harddisk) are pretty speedy good for a device that small 🙂
    • ok the speed is largely also attributed to GNU Linux Debian being very resource efficient 🙂
  • the touchscreen works very nicely and is usefull e.g. for selecting text:
  • close the lid, open the lid, resume from standby works perfectly 🙂 (well done all involved!)
  • they keyboard is also the cover, it could be a bit more “sturdy” (metal?) but it’s okay
  • is it noisy?
    • no. most of the time it sits quiet. when in bios longer time, the fan can be heared. but it’s not bad.

what could be better:

Debian 10: how to fix the wifi not working

“guess a hard block can be caused by multiple modules and/or firmware trying to use the same device” (creditz: https://access.redhat.com/discussions/3081141)

Debian 11 wifi works out of the box, in Debian 10, it is required to blacklist some kernel module drivers.

open a terminal and run this:

<span style="color: #00ffff;">su - root</span>
<span style="color: #00ffff;">apt update</span>
<span style="color: #00ffff;">apt install rfkill</span>
<span style="color: #00ffff;">while true; do rfkill list all; sleep 1; clear; done;
</span>

what this will do is output the status of all possibly hard or soft blocked devices.

now hit F7 or Fn+F7 (enable/disable flight mode = enable/disable wifi)

there should be changes visible in the terminal… still not wifi?

ok next step:

<span style="color: #00ffff;">echo "blacklist ideapad_laptop" >> /etc/modprobe.de/blacklist.conf
echo "blacklist acer_wmi" >> /etc/modprobe.de/blacklist.conf</span>
# then:
<span style="color: #00ffff;">reboot
</span>

GNU Linux how to update BIOS Firmware of Lenovo t440 without Windows :) how to fix stuck permanent function (Fn) key

how to fix stuck permanent function (Fn) key BIOS / Firmware updates: but why? if everything works, vendors often say "leave it like that" because updates can have unforseen sideeffects and not all computers are "exactly" the same X-D (a bit here[...]

#Achat #Numérique #PC #Lenovo #Thinkpad, d' #occasion, que choisir ? Que me conseillez-vous comme modèle ?
-- un petit 12' ou 13' pour la taille d'écran (format feuille A4 au max), serait suffisant, car à transporter et pc d'appoint.
-- qui serait pas trop lent,

-- mémoire vive 4Go ou +
-- clavier AZERTY
-- DD pas d'exigence particulière
-- OS Windows et je suppose, le mieux serait Win 7 ? (pas Win 10 ou 11 en tout cas)
-- il me faudrait un lecteur CD ( Des 12 ou 13 pouces avec lecteur, ça existe ?... dois-je opter pour un lecteur externe par USB ?)
-- pas trop lourd, pour le porter en vélo et sac à dos..
-- 200€ c'est trop... (plutôt 100-150€)

Voici un exemple de recherche :
https://www.leboncoin.fr/recherche?category=15&text=lenovo%20thinkpad%20windows%207&sort=time&price=min-200

Je vois plein de trucs passer, mais je ne sais pas ce que ça vaut, si c'est pas trop vieux et donc trop lent .. ?
Je ne m'en servirai que pour de la bureautique internet et basique multimédia.

Quel modèle me conseillez-vous svp ?

Merci.

(je ne veux pas y mettre trop de pognon... j'ai déjà un PC perso Thinkpad, sous Linux, un 15,6'... )

Nutzt hier jemand zufällig ein #thinkpad (in meinem Fall ein #t440p) mit einem ThinkPad Pro Dock (40A1)? Ich kriege es einfach nicht hin, mehr als einen externen Monitor daran zu betreiben. Wenn ich 2 Monitore über DP und DVI anschließe, erkennt der Rechner zwar beide Monitore, aber einer der beiden bekommt partout kein Signal. Mit meinem alten x220 und dessen Dock klappt das ohne Schwierigkeiten. Irgendwie habe ich im Netz aber noch nichts hilfreiches zu dem Problem gefunden. :(
