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.)
- Plasma Mobile Site:
- 2016 Thread on using Ubuntu Mate image as base
- Sept 2018 Wiki w/ how-to's and troubleshooting
Let's get some Soma FM DefCon station playing for some background music.
- Community Supported Online Radio for Hacking!
Clean up my workspace real quick...
Going to try with a base install of Raspbian Stretch Lite from:
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.
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 the Debian upgrade gods be on your side!
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.
OK, so maybe more of a footshot?
@TheGibson - Yeah. It seems to change the config file... but I'm looking at the screen and not seeing anything different.
Mind you, I'm ssh'ing into it to change the config. Wonder if that's why. Does ssh create a different desktop session than a locally logged in user?
Brain hurting now.
Ok... opened a console locally (using my tiny little 5inch screen!) and it does appear that ssh'ing into it opens a different "desktop environment" insofar as using kscreen-doctor doesn't affect the local settings.
Maybe. I'm learning this shit by doing... don't see much documentation. But that's probably my inability to use internet search engines.
It's been a long time since I've needed to differentiate between SSH and desktop user... but I know it uses the same profile on Ubuntu...
@TheGibson - Yeah. This is wonky. Hmm...
that said, the fact that the only real issue I've run into during this whole thing is screen rotation is fine!
Everything else seems to work... if I want to use a phone that's always in landscape mode! :P
@msh - Lol! Still is!
(PlaMo developer here)
Screen rotation largely depends on DRM driver (vc4 in case of raspberry PI I assume?) and also very recent kernel. I did some lookup and it seems to me that weston does support it so should work in theory with kwin_wayland as well ™️
But since this is not case, Can you please send me logs of kwin_wayland, (See wikipage on how to setup debugging) and dmesg?
You can reach out to be on Freenode (bshah), or email firstname.lastname@example.org
@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
