Hello,
Today i was working normally with Air Manager and two license of Air Player Desktop 4.1 running on two Raspberry Pi 4B.
I decide to try remote desktop using RealVNC. The AP on RPi(No.1) works perfect, but in the RPi(No.2) AP wont start at boot, and trying to manually start sudo ./Bootloader, it try to start, but the program aborts for a libEGL warning: DRI2: failed to create dri screen
The only difference between the two RPi's was the VNC instalation method on both Raspberry's. One was using desktop and the second using command lines:
RPi(No.1)
• Menu › Preferences › Recommend Software › Internet
• Install VNC viewer.
• Menu › Preferences › Raspberry Pi Configuration › Interfaces
• Enable VNC.
RPi(No.1) (with the issue)
• sudo apt update
• sudo apt install realvnc-vnc-server realvnc-vnc-viewer
• sudo raspi-config
• Interfacing Options › select VNC › Yes.
Any ideas?
----------------------------------
UPDATE:
- Rebooting the RPi(No.2), the Air Player auto start works perfect:
- Ending Air Player and restarting using sudo ./Bootloader fails:
Air Player 4.1 on RPi4B fails to boot after installing VNC server

Use a PC, you can get one cheaper than a single Pi and it will be far more capable

Yes jph, we use a Main PC with the flight simulator, 3 PC's for the video projectors, 1 Pc for instructor running Air Manager and 4 Raspberry Pi 4B (for now), running Air Player and it works great, so stop trying to make me cry, hahaha

Lol
Yeah, that 1 extra single pc, a 3rd gen intel i5 at 3.4 GHz for example with a gtx 970 and 8 ghz of ram can be set up for less than 150 euro from an ex corporate pc.. Lenovo tower ITX preferred due to standard component usage and replacement. . You can hook up 4 monitors directly to that with one copy of air player or manager. The pi is grossly overated and grosly overpriced. Anything for an easy life. I have 4 edge 72s with 3470s and gtx 970s. They are as cheap as chips.

Next week I'm back in the office with Jasper, I will ask him.

Gonna try to translate his reply to English.
I think it is a VNC configuration issue. Maybe you can ask the user to compare the (display) configurations? Or a simple 'echo $DISPLAY'? And if this is different then ':0' : 'DISPLAY=:0 sudo ./Bootloader'.
But note that we cannot cater for all sorts of configurations and modifications. It is made to work with 'default settings', if you start modifying then this is at your own risk.
