Hello,

First of all, sorry for my bad English...

I've got Raspberry Pi MODEL B, and I was trying to increase my RAM unsuccessfully (using USB swap and/or zram) when I realized that this command was showing this:

Code: Select all

free -m

Code: Select all

             total       used       free     shared    buffers     cached
Mem:           122         91         31          0         12         60
-/+ buffers/cache:         18        104
Swap:          127          0        127

I thought that the Raspberry had 256 MB of RAM, but it shows it has 122MB (half of RAM).

I'm a newbiee in this. Did I made a mistake at interpreting what debian tells me? Is my Raspberry corrupted?

Thanks,
Raúl Suárez

The total memory is shared between the o/s and the gui.

A part of the 256MB of RAM has to be reserved for the GPU, this can be either 32MB, 64MB or 128MB, depending on the need for video rendering etc.

Depending on the version of a file start.elf in /boot on the SD-card the creator of the OS can choose which "memory split" is optimal for the use of the system, default split for most full featured desktop distro's is the 64/192MB memory split, but a 128/128MB split is indeed also possible, as is a 32/224MB split.

Thank you both for this ultrafast reply. I did not know about that

Help! I have attached everything in the obvious places, even the ethernet cable, and turned it on, but o image on the screen so I can't tell if anything is happening.

1. How do I get a picture?
2. The OS I have downloaded still shows as being 'zipped' on my SD card, is this right, if not, can someone give me a step by step guide to get the OS system on my SD card properly?

Many thanks,

All the instructions to set up the card are on the Wiki. Link at the top of the sites main page.

Hi,

I've just tried to set up my Pi (model B), but I'm having some trouble! I've got all the components (power, mouse, keyboard, hdmi, SDcard - with Raspbian “wheezy”) but when I power it on, after booting it sends me straight to the "Raspi-config" menu. From which my attached mouse and keyboard do nothing!

Just before I get whisked off to the config menu it prompts me to type something along the lines of "startx" (it's there for a split second before the menu comes up) if that is of any use at all?

Very eager to start playing around with it, so any help would be most appreciated.

Thanks

P.S.
Quite new to programming so sorry if I've missed out key info!

I'm locking this thread as a lot of different issues are getting lumped into it that should have their own thread devoted to them. If you have a question in this thread that has not been answered yet, please make good use of the search feature of the forum and if you can't find an answer, make a new thread in the appropriate sub-forum
