BBB, /dev/fb0 missing

Good morning :slight_smile:

Using: bone-debian-10.3-iot-armhf-2020-04-06-4gb.img

added lxqt

All good except /dev/fb0 missing

Ive searched extensively and cannot find a solution.

My conclusion : image built without frame buffer support OR bug
I could downgrade to an image with lxqt included: [ Debian 9.9 2019-08-03 4GB SD LXQT ]

Any assistance would be most welcome :slight_smile:

Regards Andrew


More, i set up another SD with:
Linux beaglebone 4.14.108-ti-r113 #1 SMP PREEMPT Wed Jul 31 00:01:10 UTC 2019 armv7l GNU/Linux

ls /dev still shows no /dev/fb0

cuse mmcblk1boot1 stdout tty32 tty58 vcs1
disk mmcblk1p1 tty tty33 tty59 vcs2
dri mmcblk1p2 tty0 tty34 tty6 vcs3
fd mmcblk1rpmb tty1 tty35 tty60 vcs4
full mqueue tty10 tty36 tty61 vcs5
fuse net tty11 tty37 tty62 vcs6
gpiochip0 network_latency tty12 tty38 tty63 vcs7


This makes me think /dev/fb0 was removed quite some time ago as i have older images where /dev/fb0 is present:
Linux fft-gate-cam 3.8.13-bone40 #1 SMP Fri Jan 31 07:31:37 UTC 2014 armv7l GNU/Linux

ls /dev for my older image…

Well, it’s enabled:

Hi,
I just flashed the same image:
https://debian.beagleboard.org/images/bone-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz

and it seems I have same problem: no /dev/fb0 .
Is there some setting I should check?

Thanks

Same problem using:
bone-debian-10.0-iot-armhf-2019-07-07-4gb.img.xz
no /dev/fb0

While I confirm it’s available on:
https://debian.beagleboard.org/images/bone-debian-9.9-iot-armhf-2019-08-03-4gb.img.xz

I think it’s something related to Debian 10 releases.
