Linux (LXDE Stable) VGA not working

Technical Support

Hey,

I just started up that board, the VGA did work fine with the Easy Installer thingy on it. I connected internet via Ethernet cable, then the Easy Installer listed a few things, I first loaded the easy installer 1.8 (it had 1.1 or so). After reboot, I chose the LXDE (Stable) Linux.
Then after reboot, the VGA did not work anymore.
I set the JP10,12 to “USB” and connected a terminal program.
There I can login and do stuff, but nothing on the VGA, monitor says “no signal”. The cable/plugs are fastened with screws :wink: Already checked that, it’s not that.

What could be wrong?

Hi

Did set the vidargs variable to match your use case?

After you read this page you should come up with something like:

setenv vidargs 'video=mxcfb0:dev=vdac,640x480M@60,if=RGB565 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M'
saveenv

Max

Thanks, it would be neat if that page also mentioned at the beginning (unless I overlooked it) that this only works via serial console, when preventing boot by a keystroke in the console at the right time :wink:
Like mentioned in the accepted answer here:

Btw, is it “normal” for that linux image, using VGA at something like 800x600, that the desktop freezes for half a minute after moving around a window a bit?
Or should I make a new thread for that?
The desktop does not seem awfully useful that way…

The command @max.tx provided is a u-boot command, so need to stop in u-boot using console.
The console is very important tool in linux environment.

No, we have never heard of this issue. Could you ask a new question please?
