Re: Raspberry Pi 3 microSD card slot - spring ejection?

I think it's a bit backward to switch from the spring slog type. I currently have the RPI 7" screen which connects to the pi via DSI ribbon cable, which happens to be just over the micro sd slot. Now with everything bolted, it's so fiddly hard to take out sd card, and i do switch cards quite freque...

Your mileage may vary but at 128 MB my Pi3 works great with the OpenGL driver, if you set it above 128MB, it won't boot.

You can have the swish OpenGL driver or you can increase GPU RAM above 128 MB, but you cannot have both.

Re: Video memory unadjustable since update

OK, thank you. For the moment I have it set at 240 and the command line tells me the same. I don't use the OpenGL anymore, no matter what setting I tried, it would give me a black screen. I would guess it is setting GPU memory to 240 MB which makes the OpenGL driver die. If you set it to more than ...

Re: Sense Hat and Official Case Not Fitting

Out of interest, were those with a Pi2 or Pi3 official case? The pictures in the original post show a Pi2 case nearly fitting without modification. My Pi3 case does not anywhere near fit with a Sense Hat in place. The problem is not the inside height, but the fact that the red lid now has female ca...

Re: Sense Hat and Official Case Not Fitting

It would be nice if somebody made an injection molder version of the official Astro Pi case. I'd buy one in the blink of an eye. If they ever get that PiJuice board out, it would be quite cool if the PiJuice and Sense HAT don't happen to want the same GPIO pins. Astro Pi is quite roomy, would make ...

All very sensible guesses so far. Based on no evidence of course but I think it would be cool for the Pi to eventually incorporate Sense HAT type features if they ever get cheap enough, so my outlandish guess: Accelerometer

At the present time, the gains made by having a reliable and efficient open source driver for Linux far outweigh any hardware disadvantages compared to the other GPUs. That hits the nail on the head.

Not sure how you persuade all the now Ex-Brcm people who know how to make the VC5 to come back. These aren't the VC5s you're looking for. . . Does any upgrade to the GPU have to be that upgrade? Couldn't there be an incremental upgrade where it is still a VC4 but the things that actually matter for...

Re: Why didn't we go with Mali?

In a nutshell, he said that all the work on Wayland has been put on hold and they are waiting for Eric Anholt's GPU driver to reach a similar level of maturity. And then after comparing both of them they will finalise what to use. I personally vote for the gpu driver as it would be able to natively...
