Hi Community!

Is there a way to enable video output to CRT (VGA)? Used different “vidargs” values for U-Boot, yet without success. OS image is Apalis-iMX6_LXDE-Image_2.7.4. Display resolution 1024x768.

Hi

Please have a look here. for details.

I expect the following in U-Boot to change the Linux output to go to the VGA connector.

setenv vidargs 'video=mxcfb0:dev=vdac,1024x768M@60,if=RGB565 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M'
saveenv

Another question: I am porting Debian 9 for the module. I cannot run Xserver/lightdm on it. Debian lacks proprietary Vivante libraries so I’ve copied the requred files (dri/drv/openGL/etc.) from Toradex image. But Xserver fails to start with error:

[ 185.245] ABI class: X.Org Video Driver, version 20.0
[ 185.246] (EE) vivante: module ABI major version (20) doesn’t match the server’s version (23)
[ 185.246] (II) UnloadModule: “vivante”

[ 185.246] (EE) No drivers available.
[ 185.246] (EE)
Fatal server error:

Is there a way to get more recent Vivante files?
Xserver package version 1:7.7+19.
