Re: Adjust screen size with OpenGL driver (vc4-kms-v3d)?

What exactly is supposed to be the OpenGL resolution? I've tried many monitors, and none of them work with it. The best I could get was highly distorted without going into standby, and I was sitting there for a long time trying to manually set the resolution, and it would just blank out at any prope...

Wacom tablet support broken

On 2016-12-16 I update my pi, and found my wacom tablet not being set right. It turns out xserver-xorg-input-wacom was removed because xorg-input-abi-21 ( a dependency) was removed from the repository. Could we get an update for the wacom lib or something?

Re: RPi3 usb over-current change

The thread says you don't even need to replace or short the C97 connection, so you can crush it with a pair of pliers or a small knife and use a powered USB hub. If you don't use an adequate soldering iron you could damage the contacts, and without doing something about C97, you won't have any worka...

Is there a different way you can write an image? win32diskimager, and a raspbian-only image for example?

Re: OpenGL-driver screenmodes

I tried that link on a 1024x768 screen. The screen moves to the right from where it was, but still out of range. Both times resolution appears to be correct, but offset is wrong and it's out of screen bounds.

Re: Portable Power Bank for Raspberry Pi 3

The Pi3 is limited on voltage usually, not current. Like 4.8V would probably leave it permanently blinking. Most pi3-specific supplies are 5.1V and some even advertise >5V at 2.5A draw. Unfortunately I haven't seen any pi3 specific batteries. "doesn't work" is also a relative term. I can use two pow...

Re: Raspberry Pi 3 Bluetooth Setup

There's probably a device list that has the gamepad in it. Look for a console command to see if you can poll a service or get a list of devices, and see if the controller is in it, and if not, re-run the connection script. Could be as simple as a dumb script to see if *gamepad* is present in the ou...

Re: New Open GL Driver, Bug report thread

After an update, the monitor now detects an invalid signal even though it's showing the same m...

Re: Extreme Tux Racer

It is not playable. Firstly, you were not able to enable OpenGL drivers in the raspi-config, so the driver was using software rendering. The CPU on the Pi is limited enough as is, and a software renderer for an experimental driver on a low-powered is a terrible joke. Do not even try if the OpenGL dr...
