Going to work on my phone project for a bit. Just tool around...
Ordered a baseband from Sixfab, but something got messed up in delivery. Need to sort that out.
In the mean time, I'm going to try to install KDE Plasma Mobile onto a Raspberry Pi 3 B+.
Will post a screenshot if I can get it working.
Will livetoot it in the meantime.
(Understand I may not get anything working... just have some spare time and want to tinker around.)
Let's see if we can get #KDE #Plasma Mobile onto a #RaspberryPi.

Let's get some Soma FM DefCon station playing for some background music.

Clean up my workspace real quick...
Going to try with a base install of Raspbian Stretch Lite from:
Updating raspbian, configuring the pi for US localization, setting up SSH, etc.
Changing the Debian repo from 'stretch' to 'buster' within apt.
AHH SHIT!!! WE'RE IN TESTING!!!
apt update && apt full-upgrade
And.... I'm going to go grab a coke while that's going on.
Fuck... that's a gig and a half's worth of data.
Glad I'm on ethernet.
Ok!!!
That seemed to work!!!
Everything is working on my monitor...
Let's see if I can get it working on my 5inch touchscreen.
Ok. Touchscreen is working, but layout is landscape.
Need to change it to portrait, but the typical adding "display_rotate = 1" to /boot/config.txt is not working.
Going to try using xrandr to rotate the screen.
k... a couple of things.
Attempting to configure the display via raspbian's /boot/config.txt is overridden by KDE Plasma Mobile settings (I'm not sure where yet.)
You *can* configure things in config.txt, such as GPU memory allocation, just the display settings are changed once KDE Plasma loads.
Using the @kde Plasma Mobile GUI display settings to rotate brings up the error "Sorry, your configuration could not be applied. Common reasons are that overall screen size is too big..." etc.
Screen size is 800x480 on a 5in monitor.
"Enabled more displays than supported by your GPU" doesn't fit it, because I only have one monitor.
Time to duckduckgo this...
May be an issue with kscreen.
Running kscreen-console via ssh and it's outputing a json file
(~/$ kscreen-console json)
Wonder how I edit that json file... where is it?
Ah... kscreen-doctor is a thing!
K.
damnit... my monitor name has a space in it. I FUCKING HATE SPACES!!!!
This is gonna shit over everything isn't it...?
well....
Running:
kscreen-doctor output."ADA HDMI-A-1-1".rotation.left
*seems* to work. The json rotation is changed from 1 to 2.
But nothing on the screen changes.
A reboot doesn't do anything and the json is changed back to "rotation": 1
Hmmm....
@tinker
May the Debian upgrade gods be on your side!
@tinker
xrandr? thats brave
@tinker I thought xrandr didn’t work on pi? And display rotate only works over hdmi, I think.
@ajroach42 - yeah.... I dunno. it's not working right now... so maybe you're right.
The KDE GUI settings allows monitor control, but it's not allowing me to rotate the screen. Giving me an error.
The config.txt rotate setting isn't affecting the actual output.
The touchscreen is over HDMI. The monitor is HDMI, and the touch overlay acts as a USB device.
I'm trying to give the GPU more memory to see if that helps.
@tinker I was only able to get mine to rotate on reboot, and that was done via the config you mentioned.
@ajroach42 - Yeah, I've gotten that to work on basic raspian... it's not working now after I've installed all the KDE plasma stuff.
Maybe I need to try again....
@tinker which screen? Does it really support a higher resolution?
@j_angliss - No, the screen only supports 800x480 (or 480x800). And that's what it's set to. It is working in landscape mode right now. Just trying to get it to flip to portrait.
@tinker gotcha. Read it as you were expecting more. Odd it's not picking up rotation settings.
@SwooshyCueb @kde - Huh. :( Alright.
@tinker Um, it's "some coke". Coke, like sand or snow, are uncountable :-)
@m4iler - lol! A "soda" or a "pop" or a "soda pop" or a "carbonated beverage" then :P
Ok.... that *seemed* to work...
Creating user 'phablet' and deleting the 'pi' user.
Done.
Added Plasma specific repos.
And now installing Plasma specific tools.
