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:
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
@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
@tinker love that station when I need to focus and work
@woland - Same. Mostly non-lyrics, plays and moves into the background. Never distracts. Kampf and the other DJs do a damned good job.
