Re: [PD] [rpi] X11 forwarding woes
Root cannot open a display owned by another user. Logging in as user1 and then running a forwarded X application as user2 will fail unless user2 can write to the same display. As for ssh, I think -X is deprecated in favour of -Y for many reasons Also, why use ssh? Unless you are exposing the RPi directly to the internet (It is a COW installed system, not a RO live system so could be compromised), then why bother? The encrytion overhead is quite a drag on bandwidth. At least turn the cipher to a lightweight one like Blowfish. Otherwise, open the X using xhost and export a display setting. cheers, Andy On Mon, Jan 28, 2013 at 03:26:01PM +0100, Charles Goyard wrote: Hi list, just starting using pd on the rpi.

Hi, archlinux on my pc, and raspbian on the pi. Note that others programs behave well.
