Re: unroot the RPI

Not sure what you mean? The standard Raspbian distribution comes with a default user of 'pi'. Tis is Linux so you can create whatever users you want.

Re: NOOBS, Hot-Swapping

The only current way to achieve multi-boot in the way described is to make use of BerryBoot. Even this does not allow for non-Linux distributions and only ncludes a limited number of distributions as standard although there are instructions on adding new ones.

Re: Cannot get pi to work

Most cheap USB keyboards should work fine as long as they have no special features that might result in excessive current draw. I have seen one for just a few pounds in places like Tesco. I have some very small USB keyboards that are great for using a Pi in a mobile scenario. I am surprised that you...

Re: Cannot get pi to work

You mention the green LED flashes for a short while. If that is the case then the Pi is almost certainly booting OK and the issue is getting the Pi set up to recognise your display. The main thread discussing this is http://www.raspberrypi.org/phpBB3/viewtopic.php?f=91&t=5851. Many displays need ent...

Re: PWR is on, ACT flashes once, no more action

The problem is likely to be that the new Pi has memory chips hat are not recognised by the boot code included on the SD for the distribution you want. This is particularly likely to be the case with Micron (identified by a M symbol) or possibly Hynix memory. The answer is normally to update the boot...

Re: HOWTO: Move the filesystem to a USB stick

There are two things that are relevant: - Card ratings are based on serial writes. They do not necessarily tell you about random read and write performance which is important for the pi. - You are constrained by the interface speeds supported by the hardware. The SD interface is reported as peaking ...

You can insulate it with anything appropriate. However it is already insulated, so why do you think you need additional insulation? The cable is only 6" long so what is it going to need insulating from?

I have used that sort of setup without issues. The Pi micro-USB Power port does not have its data lines connected so that is not an issue. If you have a rev 2 Pi (i.e. one with mounting holes) then there is a good chance that you will not need the red cable at all as the hub may 'back-power' the Pi ...

Re: Trying to Remove OS + Install New

If you are writing a distribution that is an image then you do not need to reformat the SD card first - simply repeat the process you used for the first OS. The process rewrites the partition tale and directory structures which is why you do not need to clear the SD card first.

If you are using a disk editor, then just let it default for the end sector - that will be the physical end sector.

I am not sure that it is under software control at the user level (although I could be wrong). It is normally used to indicate SD card access in progress (read or write) so in normal use it is on only some of the time.

Re: Motorola Altrix Lapdock loses HDMI video after closing L

I treat that as a 'feature'. It means I can force the equivalent of a power on/off without needing a switch on the power supply.

However I guess it would nice if there was a way of making it optional without the need to do hardware modes to the Lapdock.
