#203300 — Low-Cost Tablet PC suitable for Debian

Hello *,

I am searching for my farm works an inexpensive (In the summer
it is so dusty here, that nothing realy survive, including my
ThinkPad T400 from which I have bought 6 pieces and currently
using the 3rd one) TabletPC 10-12".

However, all 10" TabletPC I have found on AlibabaExpress are nice,
IF YOU ARE SATISFAIT WITH ANDROID!

They have this stupd MTK CPUs on which I can not install Debian.

Does anyone know a TabletPC with 10-12" Size, Wifi, GSM/3G and
on which I can install Debian from DVD or external TF Card?

Note:  Of course I could use Android and then my self programmed
       Web-Apps, but then the Wifi is the limiting factor and my
       measuring devices are not working as expected with Android,
       because I can not transfer the data from the Android-Apps
       into my Web-Apps...  :-/
       Another thing is, that ALL Android VERSIONS are calling
       home and transfering unknown data... which is inacceptable!
       Also my prefered Programs do not exist in suitable
       conditions on Android.

Thanks in advance
Michelle

Hello Michelle,

didn't find any for debian but maybe lineageos > https://lineageos.org/

is worth a look? My weeleyfox smartphone is now 2 years running it and I 
just got me a
'Asus Nexus 7, 7 Zoll Tablet, 1,5GHz, 2GB RAM, 32GB, WiFi, Android'
on ebay, that will no longer suffer under android.

LineageOS is nice, I strongly recommend it, BUT it is Android (just
a nicer distribution of Android), so it doesn't fit the requirements,
I think.

it's android without the "I'd like to call home' parts, if you choose 
the bare install. You got to use fdroid or similar for package 
installation then.

AFAIK the bare install will still call home: every time you connect to
a wifi network it performs an HTTP request to a Google server in order to
detect whether the local connection gives you access to the internet or
not (and if not, it presumes it's a captive portal and offers you to
launch a browser to sign in).

I've always wondered how Android (and Windows) "know" whether you're
connected to the internet or not. I guess what you say make sense. Is
this documented somewhere? Is there a way to change the HTTP request to
some other host of your choosing?

For Windows (Vista), we find some documentation here:

https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-vista/cc766017(v=ws.
10)

https://superuser.com/questions/277923/how-does-windows-know-whether-it-has-internet-access-or-if-a-wi-fi-connection-re

Is there anything like this pre-made for Debian? I suppose it would be
easy enough to script.

Supposedly there is, but I haven't found one that works on my system yet.

Good to know. While looking into this a bit, I found some instructions
for disabling it:

I didn't install google 'services', so there is only some device 
statistics communication with lineageos.org, which can be disabled in 
the privacy menu.

Anyway I doubt, any lineageos powered device would have "2-4 USB ports"
or  "Serial RS232/485 port".

Neither did I.  The above description has nothing to do with "google services".

Forgotten one thing:

It can be also an Open-Frame PanelPC, because I have BIG LiPoly cells
of 6Ah and 12Ah availlable and can also build my own housing.

Adv.:    I have Serial Ports, more USB, can have an attached heating
         element... Direct CD/DVD support...

DisAdv.: Need external USB/Serial GSM/3G Modem and mostly USB-Wifi
         adapter.  Higher Power consumption, but it does not realy
         matter, because I have everywhere 24V DC availlable from
         Solar- and Windenergy...

So I need generally:

1)  2-4 USB ports
2)  Serial RS232/485 port
3)  Ethernet
4)  Wifi
5)  GSM/3G
6)  Touchscreen
7)  Possibel external keyboard
8)  Mouse/Trackball

Note: I can not get my BananaPI (because it has CAN) with
      a big 1920x1280 12" touchscreen Display running ...
      Otherwise it is just perfect for its 38€.

Tablets with such a collection of ports are unusual (to say the least).

This is typically included, otherwise it's not much use.

Chromebooks and Chrome OS tablets could fulfill some of your 
requirements. Installing Debian on the ones with Intel processors should 
be pretty straightforward if you don't mind the IME.

You might also be interested in the upcoming PineTab.
https://www.pine64.org/pinetab

The Allwinner A64 is already reasonably well supported in Debian's 
kernel and more features are (expected to be) mainlined in 5.1 (5.2).

That's assuming you don't want to run the ancient BSP kernel and 
proprietary drivers.

Hope this helps,
Andrei

Do not expect a tablet running debian as fast as Android, as Android is very 
special software with very, very special code for the hardware.

Lots of functions are done by the hardware itself (I mean, the computing does 
the hardware itself) and not down by Android, where in debian this is all 
missing.  

Tablets are just gadgets (IMHO) and not be usable for real work. However, if 
your work is "surfing, mailing, WhatsApp and playing multimedia", then tablets 
are fine. If you need more, IMHO a netbook is more senseful.

Just my opinion.....

Me too. But I think netbooks are a thing of the past, at least at low
cost, the tablets have displaced them. I've been looking for a
replacement for my Acer Aspire One for some years. I'm a difficult
customer in that I want at least two real USB ports and if at all
possible, wired Ethernet. I need a computer: if I wanted a toy, I'd buy
a smartphone.

I've just bought the nearest thing I could find, which is significantly
bigger but still much smaller than a 'real' laptop. Acer again, 11.6"
screen instead of 9" (I think the 9" displays all go into tablets) and
with a couple of USB ports AND wired Ethernet. Win10, but that's no
problem. The Aspire came with Linpus, which was a cut-down version of
Fedora. It was missing iptables kernel modules, and I didn't fancy
compiling a kernel for exotic hardware, but I found Ubuntu Remix would
work. Eventually I lost patience with that and tried straight Debian,
which pretty well worked, which I hadn't expected.

I have played with a pocket-sized tablet, which does an excellent job
of replacing an old out-of-support sat-nav. But though I can install
MariaDB and a web server with PHP, they won't run for more than a few
minutes. It's probably easily fixable, but there's no supported way to
get any real control of the thing. I would have to use some random
hacker's malware to do that, which I don't find acceptable. I don't
feel that the thing actually belongs to me, I'm just renting it from
Google, and doing with it whatever Google generously permits me to do.

> Must it be a tablet?

The main requirement on that side seems to be resistance to dust, so it
has to be fanless and ideally closed more or less hermetically, so
a non-mechanical keyboard is likely preferable as well.

I think mainline Linux support for some ARM SoCs has improved enough
that Debian can probably be installed on some of those cheap tablets (I
know I've seen mention of people doing just that with some tablets using
Allwinner SoCs), but figuring out which ones work acceptably and which
ones are hopelessly unsupported is far from obvious.

Maybe a simpler solution is to be found at
https://www.laptopmain.com/fanless-laptops/

E.g. maybe something like an Asus Transformer Book could do the trick,
tho I'm not sure how well it works under Debian.

Yes, this is a point, I did not take care. However, an external keynboard 
might be also workable, as it is not expensive and can easily be exhanged.

For the problem with dust, a toughbook might be the best solution, but it is 
expensive and heavy. 

I believe, most users think, that a tablet is the same as a personal computer 
or a notebook - it is NOT! Fully other architectture (i.e. ARM processor, 
graphics chip)  and so on.

Back tio the dusty problem: Every hardware with coolers and moving parts are 
bad choices. Dust will scratch the surface! (A foil will inhibit it). 
Keyboard? Use a water proof keyboard. 

However, I still believe, a netbook is the best choice, as a keyboard is easy 
to exchange. 
- Dust in the netbook can be avoided, by self improved filters. 
- Everything can easily be exchanged, when it is really defctive. 
- You have a real harddrive (mine is a standard SSD) 
  and you do not loose data, when the mainboard dies. 
- It is fully suppoirted by debian and even Windows
- Powersupply is exchangable!
- system can be upgraded (more memory. bigger harddrive)
- fully standrized ports (usb, vga, IEEE, network)
- wlan card with "special" options (monitor mode)
- low price
- good to handle (typing on a mechanical keyboard)

I thinkl there are more advantages, but I will not persuade anyone.
My own opinion is, that tablets are just crippled gadgets and for hard work 
not really usable. But that is my very own opinion, please accept.

Hope this helps. :)

SCRATCH THAT.. This few seconds later, I remembered it ALSO... needed
to potentially be portable...

And NOW it's coming to mind that touchscreen was also mentioned
meaning that might be needed for some reason as to why tablet was
specifically referenced.

Not all bad. Maybe somewhere there's a shop that could still make that
screened contraption for theirs.

With the dust protection I meant more, that the cooler wholes for airflow are 
covered with an airfilter, so that dust could not reach the inside of the 
computer, but air can. You can put this yourself into any computer. I suppose, 
you know, what I mean (my bad Engllish). 

I also thought of using a box, but then you need an external screen (think of 
a RaspberryPi i.e.). However, using a RasPi came also in my mind as it needs 
no cooler (passive cooling is enough), should be fast enough and cheap. And it 
is also small and light weighted. And there are touchscreens available for it. 
It is fully debian supported. Mouse and keybpoard can be wireless and easily 
be exchanged when full of dust. As mouse you can aslo use a touchpad (which 
you can protect of scratches with a foil).  

Also thought of a micro mainboard, but these also need an external screen and 
a cooler. So bad idea,

However, you some tablets can still be diassembled, so you can put it into 
your own dustcover. And needs no cooler. 

But please remember: It is no full debian! Although: Some tablets are able to 
run kali-linux (like the Nexus One), which is based on and 99 percent debian.

Just my ideas..... Hope this helps.

Best wishes 

Hans
