Re: Running Raspberry Pi Headless

I'm finding ssh access to my Pi to be somewhat slow at times - Press a key, wait 10-30 seconds for a response kinda thing. Running a process in the background to ping the Pi helps to reduce the lag a bit.. Over short distances, I found an RS232 connection to be much faster and reliable with the add...

Re: Can you rebuild code to run faster on the RPi?

Can you? Perhaps.... The speed of code on any processor in a system is a rich topic for discussion. The compiler and friends has a long list of flags and layers. Some may improve your application. First fire up the compiler with the -v flag. Below here is a simple "Hello World" compile with gcc on a...

Re: Memory leak causes SD card failure.

If one of the USB ports is free add an inexpensive USB stick and make a swap file on it.... Also explore limits $ ulimit -a Since most limits are unlimited by default it makes sense on a tiny system to set some.

Re: F3 Polyfuse drop 260mv on my Pi

One possible solution is to use a powered USB hub. It is possible that the USB camera is pulling enough power to trigger current limits. The 260mv drop may also be a reflection of excess current across the normally low resistance device. The apparent resistance can be reduced with a common resistor ...

Re: assault cube game server?

This is less of a linux question than it is a programming/ compile package question. The image makes a list of packages that you need. You can get the packages with "apt-get" sdl, sdl-image... I am not sure about the case. After these are installed follow the instructions and change to the correct d...

Re: Advice please on $DISPLAY

Editing the ~/.xsession for a user is a nice idea. Do make a spare user for testing. To modify that users files and test. Keep a copy of the original .xsession file to make it easy to remember what the original looked like. Recall that there are additional non-X11 pseudo terminals to login and fix t...

Re: Advice please on $DISPLAY

So to run your program, you run it while $DISPLAY points to an X server. Thank you for your comments, I have tried various ways of useing $DISPLAY to run an X server but none seem to work. How would you suggest I use $DISPLAY to open an x server for my program to use ? Thanks MM ......snip.... runn...

Re: Chromium for Raspberry Pi BETA

It can take a while.... but not a long time. You are running a bash shell script. Each step can take a while depending on your system and connecton. Always run the latest install script -- as it may change to fix some important detail. Do not forget the closing ")". The script currently looks like: ...

Re: ssh to pi

Good advice checking the login name and password for each image that you are working with. I always make myself a user account so I am never connecting as root. It is common to have root login over ssh disabled. If this is the cases no amount of debugging will help. The permissions on $HOME and $HOM...

The issue is that ipv6 is not enabled to most of the world and the ipv6 host lookups take a bit of time to error out (as they are supposed to). Stick with the c...
