from The Wiki:
Note: the "(host)" prompt indicate all the commands you running at host board (eg. a ubuntu x86 machine) the "(boards)" prompt indicate all the commands you running at target board (eg. s500 arm board)
"Host" means your computer and "boards" the roseapple pi.
For me it looks like this (unpack):
[fritz@Arch_notebook GPU]$ tar jxvf gpu_v2_1118.tar.bz2
then download install.sh and continue as described in the wiki.
don't try to follow "Install GPU driver while the board is up and running "
This is crap!
probably copy paste error :) needs to be fixed.
