NOTE: BOINC runs even if you don't use the screensaver. When the graphics application window has been found, it will be embedded into the XScreenSaver-provided fullscreen-window, the root window, the preview window or a newly created window, depending on the environment, using the XEMBED method.

Not every graphics application seems to support this, but this method has been successfully tested with and. The window created by the graphics application is then searched for using X11 window properties, such as 'WM_COMMAND'. When run, this screensaver connects to the BOINC client via RPC, asks for graphics providing tasks and starts a random graphics application. If your BOINC directory differs from /var/lib/boinc, you can use the -boinc_dir command line argument. To use this screensaver, please add the following to the 'programs' preference in your.

usr/bin/nohup /usr/bin/nice -n 19 makes a nice uninterruptible process (electric-sheep was ending itself every so often, and so it stays running when the terminal is closed)Īnd finaly when you put it all together again an excerpt from my ~/.The BOINC client software on Windows and Mac OS X includes a screensaver program, which you can select as your screensaver. I stole this from some where that i cant find but i did find where they probably took it from:

usr/bin/nice -n 19sets the following command to play nice, take up to 99% of the cpu if (and only if) the cpu has free cycles. usr/bin/nohupruns a process so it cant be stopped by a hang-up signal (when you close the terminal) Ps |grep amework|grep -v grep||will only run the echo command if the screen-saver isnt running This will always also return the grep command thats searching for ScreenSaver, so we use Grep ScreenSaversearches for the ScreenSaver.

There is some info about background jobs ('asynchronous processes') in the man page for tcsh (which is where you end up if you do man jobs, or man bg, etc.), but you have to scroll waaaaaay down to get to it.

The real point is that the fact that control-c doesn't work does not signal an error in the hint it just means you have to use kill instead of control-C. I use simple commands to go with my simple mind. (Translation: I am too lazy to read man killall.)Īnyway, how you kill the thing is your own choice. On the other hand, ps and kill are nice and simple. Probably the best thing to do is to use the killall command. This can be made fancier: other hints/forum threads have talked about combining this with grepping for the name of the command you want to kill. For example, run ps (or ps -awx) to find the process number of the desktop background screen saver, then kill that process. Since the command in this hint is run in the background (with the ampersand at the end of the command line) it will not be hit by control-C. This tip was mentioned by Ken Dyke at last night's BANG meeting.Ĭontrol-C only kills processes that are in the foreground in the terminal. You can hit Control-C (in the Terminal window to terminate the program. Performance was not good on my 16 MB card.
