Howto restrict su command to superuser only in Linux

Posted 08-26-2007 at 11:51 AM by sridhar11

The optional argument - may be used to provide an environment similar to what the user would expect had the user logged in directly.

AverTV DVB-T 777 and the remote

Posted 08-24-2007 at 05:39 AM by Caysho

I started to look at what is needed to get the remote working.

This indicates patching is possible, but there's a note about support being in more recent kernels.

The board is referenced as SAA7134_BOARD_AVERMEDIA_777 in the saa7134 source; SAA7134_BOARD_AVERMEDIA_A16AR is also mentioned, and seems to be the chipset reference - I've seen it in the win32 inf, so the 777...
