This is very bad, I've the same problem. Having a second voltage regolator on 3.3V is blocking the boot.
why do you connect both 3.3V regulators together? Simply connecting the outputs of switching DC/DC regulators just leads to trouble

Re: Multiple Frame buffer beta testers wanted

Unfortunately I've been rather busy on other stuff. There has been work done on the new graphics driver which might help support dual displays, I'll checkon Monday whether that would be of use. If that a no-go, I'll try and find time to update the modules, and/or merge the code to the main branch. ...

Why don't you i.e.buy something like this https://www.pollin.de/p/raspberry-pi-lc ... ung-121564

There are tons of such 'small monitors' available to the market.

Re: USB hub chip compatibility

Can you provide details on your non-working hubs? I've used some starting at 0,99EUR up to some 20EUR and all of them work flawlessly.

If your Hub has a Ethernet Port in addition then your comment is valid.
