Hello everyone

I have a problem.

A two years ago I created an application for Raspberry Pi 3 in Python and Tkinter.
Recently I bought a PinePhone64 and I would like to transfer this application to this device. I installed Mobian with Phosh there.

After researching the subject, it turned out that the RPi has an X11 display server, and the PP64 has a wayland.

Is there any possibility to run my application on PP64 without rebuilding the GUI?
How to do it?

I tried to install X11 server.

We’re building a HDMI Display Driver for Apache NuttX Real-Time Operating System on Star64 SBC, but the JH7110 Display Controller isn't documented!

In this article, we decipher the Linux Driver for JH7110 Display Controller and figure out how it works...

(1) What’s inside the Direct Rendering Manager (DRM) Driver for JH7110
(2) How it controls the Display Registers
(3) To handle the Display Pipeline, Display Planes and Framebuffers
(4) And how it talks to HDMI and MIPI DSI (Display Serial Interface)
(5) How we might implement our NuttX Driver

I cannot boot from another drive plugged in externally, it doesn't recognize anything plugged into any of the USB ports. I know only the USB 2.0 on the left side is bootable, but it doesn't show anything is plugged in to any port.

Any help would be greatly appreciated.

I have installed Abiword on a PinePhone with PostmarketOS. I have also installed PcmanFM. With PcmanFM I can see Abiword files which I stored on an external SD card. I was not able to open them from there with PcmanFM to this date.

So I tried to open them from Abiword. With PcmanFM, I can see my external SD card. But if I try to open files with Abiword from my external SD card, I cannot find the SD card. It is not listed somewhere. Where can i find it?

I have installed Abiword and PCManFM on a Raspberry Pi4 with LeepspsvideoKDE plasma which runs on Raspberry Pi Os. I have stored Abiword files on an external SD card. If I view the external SD card with PCManFM on this setup, I can see the Abiword files on the external SD card. If I mark an Abiwordfile and hit return, Abiword starts and opens this file, which is great.

I have also installed Abiword and PCManFM on a PinePhone with PostmarketOS. As in the example above, I can see the Abiword files on the external SD card. But if I mark an Abiword file and hit return, PCManFM opens a dialogue box and ask to choose an application. But there are no applications listed which I could choose.

The second option  PCManFM offers to open a file is to enter a custom command line. I can also browse there and search for an application. I am looking for the Abiword application.

I am a Linux beginner, so I changed back to my Rasperry Pi 4 where it is easier for me to find files. Abword is also installed there. I searched with PCManFM for «Abiword». I found some files. But which file do I have to select to start Abiword?  With none of the files I found it was possible to start Abword. How can I do this?

Hey guys,

I'm really new to the whole PineTime concept and I'm trying to get a heartrate reading which needs to be sent to a PC. I can figure out the Bluetooth connection but I don't have a starting point to get any values from the watch to a PC. Can anyone give me a hand or can lead me to a tutorial which can give me a first step in the right direction? The tutorials I've found so far are involving an old Github which won't work anymore.

Big thanks!

power/battery usage on risc-v vs arm64?

question is, has anyone any information what is battery or power usage on risc-v cpu compared to arm64 cpu? i am thinking about possible future devices with risc-v. maybe simple cellphone. i know they're not going to happen for short term though.

Hi all, i just installed two quartz64 model a sbc, i choose manjaro arm and it runs pretty well , the only thing that fails is that, to boot the board, it needs to mantain the reset button pressed while connecting the dc power jack, after a while it loads the os.

If not doing so it doesn't boot. So i cannot reboot the board remotely (so it cannot be ran as remote server)

I am using a 64GB sandisk extreme sd (model SDSQXAH-064G-GN6MA ). I have ordered a kingston  CANVAS GO PLUS to check if things get better. Also i am thinking if an emmc module will be better, so maybe i'll get a okdo emmc module ( https://es.rs-online.com/web/p/complemen...ck/2565008 ).
What do you think? Has anyone this same boot problems?
Thanks !

This is a different problem than the one that's been reported where the screen just won't turn on at all.

It's also different from suspend/hibernate not working, because the system is still running and reachable via SSH.

The screen is turning off after a period of inactivity (even though I've set power management not to turn off the screen) and won't turn back on until I reboot the tablet. The keys light up when I press them. The USB network adapter I have shows activity. I can even SSH in from another computer.

But the screen *does* come back on after reboot, whether I use the command line through an SSH session, or whether I just hold the power button down until it shuts off, then power it on again.

I'm currently using LxQt on the factory-shipped danctnix updated to the latest with pacman.

Has anyone else seen this? Any solution, or a tip for finding what else might be powering off the screen if my desktop session isn't doing it?

my on-screen keyboard is lost on arch phosh pinephone beta edition from sdcard with tow-boot on emmc

 is there a way to find it or get new one ?
