   - Kernel : relative to /boot/extlinux/ , but you can put /boot/zImage too, it works.

+On my side I have an SD card with and ext4 partition (/dev/sda2) , and on this partition i've put the debian12 files.
 It's my debian12 rootfs.
 rw is for read/write, rootwait ( idk ) , and console etc.. to print whats happen in the console tty.

 Then when you'll look for synthesizer or helm in apt, you have more choices , and now you can try various apps like lmms, helm, carla, ardour or mixxx.
-A future improvements would be GPU acceleration, i have to dig on mesa/gpu stuff to understant how it works.
 Have fun & enjoy.

+=== Misc / Trouble ===
+Sometimes display fails if you let it displaying , maybe an triggering hibernate mode...
+Improvements could be gpu acceleration instead of using lvvmpipe.
+I have to dig ....
+In case of trouble you can always access to your / and linux with method described here [[uboot|]]
+=== Other configuration / notes for myself ===
+Instead of LXDE, it's possible to install LXQT
+To have it :
+<code>
+apt-get install lxqt
+(~ 2gig .. be patient )
+</code>
+lxqt use sddm by default
+for autologin ( change PAM options )
