How to change GPU memory split
« on: January 24, 2013, 07:34:45 AM »
By default 64 Mbyte is allocated to the GPU which is not needed if you are running console only or accessing it via SSH remotely without graphics. Having a 256 MByte board it is a huge loss. Just add this line to your config.txt in the boot to give 16 MByte to video:

Code: [Select]
gpu_mem=16

and win 48 MByte RAM.

No problem :)

/mnt/mmcblk0p1

You must mount it to access.
