Minimal Linux build for a thin client

alexanderzhirov

There are thin clients running a distribution built in Buildroot.
There are practically no packages in the client itself. Device drivers are loaded over the network - mainly drivers for the video card. The distribution itself without video card drivers weighs about 10 megabytes. The distribution itself has an RDP client installed (most likely a self-written one). I'm sharing an executable package that I pulled from there via ssh.
The bottom line is that clients are loaded and there is only one RDP client icon on the desktop and no additional features. Everything is cut out. The distribution is loaded over the network as PXE.

The gap is that new workstations have appeared and this distribution does not rise on them due to the lack of drivers for the video card.

I do not have the source code of Buildroot, in which this distribution was built. Therefore, it became necessary to build a similar new distribution with support for a fresh (not necessarily the latest) kernel.

Requirements:
- ssh
- openbox/fluxbox
- rdp
- midnight commander
- minimum rootfs size, preferably up to 20 MB

It just turns out that I'm picking up the x86_64 distribution for a written RDP application. It is desirable for me to use it in the distribution.

Are there any suggestions?

I think Alpine possibly fits the bill... I just checked and all those packages seem to be in the repos.

synth-ruiner I think Alpine possibly fits the bill... I just checked and all those packages seem to be in the repos.

I don't understand why the image doesn't load. I made an assembly based on a minimal file system, packed it into an archive, but it still does not load.

user@vbox:~/temp/rootfs$ ls
bin  dev  etc  home  lib  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
user@vbox:~/temp/rootfs$ sudo chroot . /bin/sh
/ # ls
bin    dev    etc    home   lib    media  mnt    opt    proc   root   run    sbin   srv    sys    tmp    usr    var
/ # 
user@vbox:~/temp/rootfs$ sudo find . | sudo cpio -o -H newc | xz -C crc32 -z -9 --threads=0 -c - > ../alpine-initrd.xz
144083 блока
user@vbox:~/temp/rootfs$ cd ..
user@vbox:~/temp$ ls -lh
итого 22M
-rw-rw-r--  1 user user  22M мар 23 12:01 alpine-initrd.xz
drwxr-xr-x 19 user user 4,0K мар 23 10:40 rootfs
user@vbox:~/temp$

Maybe I need to install something else? Are there any additional loaders?

synth-ruiner

alexanderzhirov I'm afraid this is a bit beyond me (I've never done a manual installation of Alpine) but maybe the wiki has some help? https://wiki.alpinelinux.org/wiki/Installation

alexanderzhirov

synth-ruiner I myself have little knowledge of assembly.

If someone can tell me how to make a minimal root filesystem using the kernel from the base assembly with booting via PXE, I will be very grateful.

synth-ruiner

alexanderzhirov is this any help? https://wiki.alpinelinux.org/wiki/PXE_boot

Fellow maintainers, is there a pure basic minimal image of the Solus distribution?

Staudey

alexanderzhirov is there a pure basic minimal image of the Solus distribution?

No, there are unfortunately no minimal Solus images. That's not the intended use-case for Solus.

alexanderzhirov

Staudey No, there are unfortunately no minimal Solus images. That's not the intended use-case for Solus.

And if purely theoretically - is it possible to make such an image? Isolate everything from there and leave it clean.

Brucehankins

alexanderzhirov I'm sure there is a way. With the source code and enough knowledge, you could build your own minimal .iso of just about any Linux distro.

alexanderzhirov

Brucehankins I totally agree. It remains to "have enough knowledge" 🤣

alexanderzhirov

synth-ruiner No, that's not what I need.

I'm thinking of trying to build an image through Buildroot, but I don't quite understand how to properly set dependencies for certain packages. For example - Xorg. Does anyone have experience in building via Buildroot?

tomscharbach

@alexanderzhirov hirov#65493 Does anyone have experience in building via Buildroot?

I wonder if Buildroot manuals/forums/support would be a better resource for you than this forum.

alexanderzhirov

tomscharbach I wonder if Buildroot forums/support would be a better resource for you than this forum.

They don't have a forum. IRC is also silent, no one answers.

alexanderzhirov

I tried to build on the basis of Alpine, but it looks like I did something wrong.
Firstly, the image size is very huge.
Secondly, the disk image is not loaded.
I don't understand what I did wrong.
Are there any assumptions?

After 10 days, I made a little progress in my work on a thin client. Alas, nothing is working out yet. I'm blogging right here 😃
In general, I decided to make an assembly in Buildroot. I'm playing with the settings, because I don't quite understand some certain things yet. In general. After loading the image I have collected, a black screen appears. No reaction to pressing key combinations on the keyboard. No reaction to clicking the mouse buttons. I don't understand what I've missed here this time.

.config Buildroot
.config Linux Kernel 4.19.209

After loading on real hardware, there is no mouse cursor display. The mouse itself is working (lit), but no visible actions occur after clicking on it. The keyboard does not work (Logitech Keyboard K120). Everything is connected via USB 2.0. The screen is black. The last thing I see in front of the black screen is the launch of the X-server. By pressing the off button, the screen is replaced by a terminal and the computer turns off.

I was able to configure SSH and see what errors Xorg throws after startup. For some reason, the modules are not loaded.
