So I got my pine64 (1GB) up and running following the instructions in damikeh's thread ( http://forum.pine64.org/showthread.php?tid=622 ) but ran into some issues. Full run-down:
Followed instructions exactly, MATE up and running pretty easily. However, 
1. LightDM (/usr/sbin/lightdm-gtk-greeter) was popping up an error at login, and every login I have to login in twice. This error pops up every 5-10 minutes 
2. I noticed the Software Boutique is empty but haven't done much with that.

My biggest issues were trying to run Firefox. (Midori works well enough)
1. Firefox won't even pop up, crashing with segmentation faults.
2. This led me to realize that the way this build is installed, it didn't go through the usual setups, so no locales were set.
Fixed the issue:

Any chance we could get native wiimote/Xbox controller support? I have an Xbox to USB adapter and would love to use it to play games without having to re-change settings after every upgrade

Hello, I recently received my Pine 64 512mb model and have yet to successfully get it booted. I have tried installing android 5.1.1, remix os, and arch linux (all listed on the wiki page), but had no luck. I understand that these state they are tried/require the 1gb model, but I am very eager to get started with my pine. Are there any operating systems the pine 64 512mb model can run? Thanks!

So I got the newest version of Remix and downloaded the Youtube app but it will only allow me to select 480P max. Anyone have any idea what's up with that? Other than that browsing seems fine. Haven't tested much so far.

Sorry if I missed something obvious.

Thanks!

So I just loaded the new Remix OS to my board(Remix OS 2.0 Image Release 20160415 Beta). I had to wait on this version because the board I have is the 2gb one.

After loading the image up and ran the first boot. Looking at my tv i noticed the task bar at the bottom is half hidden and the icons are right up against the side of the tv. I adjust my tv aspect ratio to normal and wide and no change at all. Anyone else has this issue?

Hi everybody,

I'm searching an App for Android smartphones as my OnePlus One, who can take control on other Android device as RemixOS on Pine64.
I want to make my Pine64 usuable without any wireless keyboard and mouse.

Thanks by advance

Hello,

I received a week ago my Pine64 2GB version with  the WiFi BTmodule and it seems that the Bluetooth doesn't work.
I tried with the Ubuntu image, when I activate the Bluetooth all the other items of the bluetooth menu stays grey even after a reboot.

Did I miss something?

Also, I wonder if the WiFi/bluetooth module I received is defective, one of the connector doesn't slide all the way down,
I checked with a magnifier and it seems there is something metallic stuck in the pin 3 of the 14 pins connector.

Thanks

That's a very creative customs declaration for a product I bought for 20$, right?
