I am on Jetpack5.1( from latest sdk manager). I am using a DP->HMI converter and it works on x11 only, but not when I disable the ubuntu desktop(
sudo systemctl set-default multi-user.target) . I’ve tried modprobe nvidia-drm modeset=1 and all I see is no signal on my display, plus there are no framebuffers.
And no matter what I do I always get the following error when I run my Qt6 application. What is strange here is that the display shows the NVIDIA logo on boot, so that means no DP->HDMI conversion issues and X11 works too, but disabling the desktop causes nothing to work… egl, kms, vulkan, weston, nothing…
resetSurface: Unable to connect stream
EGL Error : Could not create the egl surface: error = 0x321c
All works fine on Xavier.
Also, the NVIDIA demo below doesn’t work. I got no frame buffers. DISPLAY=:0 xrandr has no displays.
What am I missing?
Your help is greatly appreciated.
