Minibook N4100 touch screen firmware Linux

il installed Ubuntu 19.10.
Impossible to have the touchscreen avalaible.

I tried this firmware , the touch works but not in the good place.
I tried different Coordinate Transformation Matrix but no way.

Is there a special firwmare for the minibook ?


Hi Vince,
did you find the solution?

No solution yet. I had a big problem with the bios (without flashing) when i activated Linux as OS (black screen), obliged to return to the factory, 3 months for the repair and return …
If you find a solution, i m interested.
Best ,

I followed the gslx680_ts_acpi step in (using firmware in ). Touch now works, not perfectly but works. Tomorrow i will try another way to stabilize the touchscreen

Looks like the firmware files will work fine if installed correctly.

If they’re for the same device as mentioned in the git repo and if the device have the same model of the touchscreen controller chip then it should work.

@white_sheep how did you install the firmware?

you say: doesn’t work perfectly, Is it usable?
I can also get the touchscreen to work, but there’s a problem with the position. When you touch one place, the cursor appears in another place.

I got the touchscreen working using the extracted firmware from the windows drivers with the tools from here:

the file needs to be placed under: /lib/firmware/silead/mssl1680.fw in order to be found by silead kernel module which needs to be present and loaded. this way he touchscreen gets recognized.

the next problem is the callibration. I used to calibrate the screen (note that I had to select disable rotation: no)

the libintput rotation matrix that I ended up with is

-0.003622923570787379  3.709528216791325    -0.004723837559728938 
 2.442943240520969    -0.014587762028163658 -0.008818738010799037 
 0.0                   0.0                   1.0

I modified the script from rubo77s script ( to automatically rotate the screen based on the sensors.

Im using nixos and had to configure everything by hand but more integrated distros like ubuntu might automate some of that.

hope it helps.

Hello and welcome to the forum,

This is good to see chuwi device getting more linux support
Nice work. Hope someone with minibook can make use of your finding.

Keep contributing.

“chuwi device getting more linux support” I wouldn’t go that far :wink:

I have the same problem than Alda (Linux on Chuwi Minibook 8) about linux installed on sata drive. I tested different kernel version and with the lastest 5.6 and the same problem. I can’t install ubuntu without errors, i can install fedora c31 and use it but sometimes i have some freezes. Dmesg return some errors about sata. The sollution will be to install Linux on the emmc memory but i prefere to keep windows on that.

In addition, I have a doubt about the stability of the machine. I just modified a parameter in the BIOS about OS feature and the result was a black screen with the impossibility to boot, obliged to return to the factory :frowning:

Thank you exel, i will test your matrix.

This must be something from bios side, so maybe chuwi can fix such issues in the future.

Let’s hope for the best though :slight_smile: hopefully we will see many devices with linux pre-installed and officially supported.

I had the same problems with the sata and finally installed on the emmc drive because I thought the sata was just broken. Also I still cant get the system to predict the battery state.

Would be excited to see these things fixed.

The machine is cheap and good enough. Unfortunately there’s these problems with the bios (my fan won’t turn off) and the support (aka. bios updates via media fire links in this forum’) is a total joke…

Yes i share your point of vue, in addition the linux compatibility is a joke :wink:
Too bad they had announced an official linux compatibility on chuwi’s official website :frowning:

I don’t dare to modify anything in the bios afraid of having to return it to the factory again, and for the flashing let’s not talk about it …

Concerning a linux support, let’s not talk about it, the only feedback I got on the touchsreen is that the minibook doesn’t support it under linux.
