Hi,<br>
<br>
I have installed Alpine on a raspberry Pi4 model B. I did a classic sys ins=
tallation on it with xfce4 as Desktop. All packages was installed from main=
 repositories (no edge) and i took the last aarch64 image available from th=
e Alpine site.<br>
The system boot well, Xorg work correctly and the Desktop too.<br>
<br>
But, i have trouble with dual screen. The first hdmi port (the nearest of t=
he power supply) works as expected and correctly detected by the system but=
 the second one doesn&#39;t work. It display a rainbow screen.<br>
<br>
I try to see if it&#39;s detected by tool like /opt/vc/bin/tvservice but wi=
thout any success. I try to configure the second hdmi by the boot/config.tx=
t file, but again without any success. I thought that can be a missing modu=
les to load earlier at boot time by the cmdline.txt file but i don&#39;t kn=
ow which module can cause the trouble.<br>
<br>
So, it will be very appreciated if someone have a piste to follow to share.=
