Re: XBian - Small, Fast, Lightweight XBMC solution

Expanding the filesystem on a SD with XBian is not very simple as the swap partition is located after the partition holding the / filesystem so one has to "swapoff -a", remove swap partition, extend partition, re-create swap partition at the end of card, "mkswap" the add the FS extending script to b...

Re: Windows & OS X on Raspberry Pi

It's unuseable for anything than demonstration purposes.
Get the cheapest second-hand PC you can find (Pentium II) and it will run faster than XP emulated on the RPi.

Re: omxplayer - GPU enabled video player

As the title of this thread say, omxplayer is a GPU enabled video player. If you did not activated the MPEG2 licence, the GPU is unable to decode MPEG2 files.

If the RPi didn't burned out in the 1st couple of hours, it's 99.99% sure that it won't fail later, except if you do something to it that would void the warranty anyway (overvolting, shorts, bad PSU, mechanical damage) I went on and removed D14 off of both my RPis, and after a f...

Re: [Howto] Redirect X over SSH to other PC

If you want to start another X server on linux, you can also specify the tty:

xinit -- vt8 :1

starts XServer :1 on tty8 (Ctrl-alt-F8)

just make sure beforehand that tty is "empty" i.e. there's no getty asking for a login prompt or syslog dumping messages there.

PS: has anyone tried my method ?
