Re: Slow sd card ??

The Desktop Interface on the Pi will (probably) always be slower than that on a newish PC, as the Pi uses a much less powerful processor. Also, the current graphics driver for it does not make use of the hardware video acceleration that the GPU has. A new driver is being worked on and that should sp...

Re: pgrep -n motion - difference if run from command and scr

Because you have called your script "/home/pi/scripts/motion-act.sh". "pgrep motion" will search for any process name that contains "motion", so it will match your script name and return the PID of that. The reason it gives a different number everytime you run it is because the script has a new PID ...

Re: Restoring SD card from backup made using dd

There are no simple as in one-command-fits-all ways of restoring an image to a smaller SD card. The way I'd do it (with access to a linux PC), is: Use dd to copy the first 100MB or so, just to get a partition table and the /boot partition onto the card. Use fdisk to delete the (incorrectly sized) se...

Re: USB hard drive delay

Are you using the external HDD for your root filesystem?

If so, have you added "rootwait" into the kernel command line in /boot/cmdline.txt (or just cmdline.txt if viewed on another computer)?

I have no problems booting my Pi with that setup :)

Re: SD Card/Mouse

A class 4 micro SD in adaptor is fine. That's what I use on two of my Pis. A mouse is required if you want to run a desktop environment on your Pi, but for command-line use, and first boot/configuration it is not needed. It depends on what you are going to use it for and what software you plan to run.

The problem is that you are using a public IP address on an internal network. This is incorrect, an internal address from RFC1918 is what you should be using on your LAN - per a previous posting.

/opt/vc/bin/tvservice -s will show the current state of the video output.

Unless you have overridden it with force/ignore hotplug in config.txt, it will mention HDMI when the TV is connected and powered on, and PAL or NTSC if it is off (when defaulting to composite output)

Re: Cannot resolve host name

Something is very odd if you can't ping 8.8.8.8. Pings could be blocked by your network, I suppose.

198.248.36.36 is a public IP address. Did your network admin allocate that for you?

Most people will be behind a NATed firewall/router and get 192.168.x.y, 172.16.x.y or 10.x.y.z addresses.
