Re: Updated GPU firmware

VCHIQ now supports bulk transmits of kernel allocated buffers, which should fix the oss audio panic.
Brilliant! I've been waiting for this!

Re: Clutter (OpenGL/OpenGL ES GUI Library)

It should compile fine, but it likely won't be able to get a EGL surface to render onto as it tries to get one via Xlib. It would need to be ported to use the direct access route, or for someone to port X to handle EGL windows.

Re: Xmanager to Pi

I would add that the above is quite an unusual thing to do - I added the Xnest option as I thought it might be a quick win. It has all the drawbacks of the SSH forwarding connection, such as no persistent session. For repeated use, I would recommend running a VNC server on the Pi to persist an insta...

Re: Xmanager to Pi

Ah yes - I've just tried it out on mine and Xnest isn't there by default. So, to fix this on the Pi: sudo apt-get install xnest Then: Xnest :1 -geometry 1024x768 -ac & [<-- This creates an Xnest instance at address ':1'] The above will also complain a little on the console. What should appear, is a ...

Re: Xmanager to Pi

There is another (quite important) difference between the conventional ways to remotely access Windows and Linux desktops. In Windows, remote access is often conflated with the idea of "sharing" the desktop. In that, if you had a monitor plugged into the remote Win machine, you should see pretty muc...

# benosteen X forwarding over SSH is clearly something that I really must setup. I certainly won't be bored this evening. You said earlier that you were able to log in to the Pi, but with a terminal session? If you used PuTTY, then on the connection settings, look for the 'Enable X11 Forwarding' op...

Re: Xmanager to Pi

The main conflict seems to be that @dtud wants to use the Pi in much the same way as "windows remote desktop" works - by providing a window that shows a full desktop running on the Pi. The way that many use linux headlessly is without this full desktop, but instead, to run individual applications as...

Re: Kinect - Would it ever work with a Raspberry Pi?

The quickest way to experiment is to use the python bindings for libfreenect - the depth 'image' is really a matrix of 11bit values. There is a means to convert that into a real-world distance (from 0.3 to its limit of 4m) if you have a google around. The biggest limitation is the viewing angle (47°...

Re: Framebuffer (/dev/fb0) composited in front of an EGL sur

Tried this, but was unable to get the fb to mask out it's background.

I adjusted the alpha of the new display and set the PREMULT flag - it's not great, but at least you can see what you are editing underneath the rendered output :)
