fixture editor problem

[elettrix]

Hello,
when I try to launch qlcplus-fixtureeditor from terminal I get this error:

qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.

I also tried with qlcplus-fixtureeditor -platform eglfs
but nothing, I only see the mouse pointer and error "Could not queue DRM page flip on screen HDMI1

in emergency situations I would be comfortable to have the fixture editor working from the raspberry

can you help me?
thanks

Raspberry pi4 4gb ram qlcplus_raspios_buster_20210627

Are you trying to launch the editor from SSH or directly on the Pi?

[elettrix]

Directly from the Pi

[mcallegari]

Try these

Code: Select all

export QT_QPA_EGLFS_PHYSICAL_WIDTH=320
export QT_QPA_EGLFS_PHYSICAL_HEIGHT=200
qlcplus-fixtureeditor -platform eglfs

[elettrix]

Nothing,
as before, only see the mouse pointer and error "Could not queue DRM page flip on screen HDMI1"

i also tried to flash clean image of qlcplus_raspios_buster_20210627,
but nothing same problem

I checked myself. You need to use these 3 variables:

Code: Select all

export QT_QPA_EGLFS_PHYSICAL_WIDTH=320
export QT_QPA_EGLFS_PHYSICAL_HEIGHT=200
export QT_QPA_EGLFS_ALWAYS_SET_MODE=1
qlcplus-fixtureeditor -platform eglfs

Hi,

I tried but nothing to do:

This is my qlcplus config

that's the problem

[mcallegari]

Wait, what?
You just need to copy and paste the 4 lines I mentioned above to make it work.
I have no idea what you're doing or if you're confident in moving in a Linux system, but you're surely not doing it right.

Hi,
I updated qlc+ to version 4.12.5 and now fixture editor works fine,
but how do I get out of the gui to return to the cli or in qlc+?
I tried with ctrl+alt+back but it doesn't work

[mcallegari]

CTRL-C from the shell where you launch the editor

[elettrix]

Hello,
ctrl+c does not work,
I am using qlcplus_raspios_bullseye_20220620 img and launch fixture editor with qlcplus-fixtureeditor -platform eglfs.
Can it be a problem of the keyboard layout?
