Okay, after thinking it over again, I've found a solution that works for me. For anyone else experiencing this issue:
conn=$(/storage/proptest | grep HDMI-A-1 | awk '{ print $2}')
param=$(/storage/proptest | grep "Broadcast RGB" | awk 'NR==1 { print $1}')
/storage/proptest $conn connector $param 1You may need to change the name of the interface.
In all my environments, I have to set the RGB mode of my mini PCs (all intel based) to "full", because 'automatic' fails and sets it to "limited". I do this in autostart.sh, e.g. /storage/proptest 161 connector 163 1
My issue: With each new LibreELEC version, the collector and parameter numbers change, so I have to modify the script to make it work again.
Is there a reason for changing the numbers? Or is it possibe to use proptest with a name, e.g. "HDMI-A-1"?
Another one: It looks like xrandr is missing. Is it a bug or a feature?
If it's a feature: What can be used instead to set e.g. "Broadcast RGB" to "Full"?
OK. I got it:
X11 is not used anymore, so there is no xrandr.
You can use proptest to switch to RGB full.
I updated my system (Minis Forum with Celeron N4020) with generic version. All seems fine, but the IR remote doesn't work anymore. After downgrading to 10.0.4 it works again.
Since it works out of the box with LE10 (no lircd, no ir-keytable), it loooks like a kernel issue.
Any idea?
SOLVED: After investigating a lot without a result I did a fresh install. Now it works as expected.
Hi,
after installing this build over the latest stable 10.0.1 I cant't login via ssh anymore. Neither my key is accepted nor the standard root password. Any hint?
OK, after setting the password via GUI I'm able to connect again. BUT: Why is my key no longer accepted?
Second one: There is no xrandr installed, so I can't set my graphics to RGB Full. Did this happen on purpose or by accident?
Ah,thank you. I was just wondering since I didn't change anything...
After changing the keymap it works again 
Klojum: Sorry for placing this question in the wrong forum section.
With 8.90.006 my remote doesn't work as it did until 8.90.005. Most of the keys are working correctly, but the key for the context menu brings up a message about "No PVR-Addon activated".
I use a Logitech Harmony 600 and I never changed the settings since about 3 years. So there might be a change in LE 8.90.006?
This is what I found in the debug log:
15:35:13.799 T:140619617347328 DEBUG: LIRC: - NEW 16d 0 KEY_EPG devinput (KEY_EPG)
15:35:13.805 T:140619625744512 DEBUG: HandleKey: two (0x32) pressed, action is ActivateWindow(TVGuide)
Does it mean that the setting for key 16d has changed?
