1) Questions and Answers : Unix/Linux : Problem with screensaver (Message 91403)
Posted 25 Nov 2019 by Angelo Keene
Post:

Follow up to my last post - I found some source code at https://github.com/BOINC/boinc/blob/master/clientscr/screensaver_x11.cpp that lists the command line options to the screensaver. "-root" doesn't put the screensaver on my root window like I thought it would (still appears in a window), but does provide graphics. It appears that no options are passed through to the underlying graphics program, so it may be that there is a separate configuration file that would hold the other options such as "-fullscreen", although, that option didn't seem to work as I expected when I tried it by hand by specifying -boinc:fullscreen as a command line option to the underlying graphics program.

Maybe someone will eventually close the gaps there, not sure.

I just tried it - I made sure the daemon was not alive before I edited the file, and put this line in:

  GL: 				boincscr -root				    n

Note that the whitespace in between the columns contain tabs. I duplicated another line in the file, and edited it.

Here's my machine configuration, if it helps - I'm running linux mint with the newest kernel and updates.

UPDATE: I noticed that the boinc screensaver was indeed running, but not on the root display, so I took a look at the text output when I started the tool by hand:

Then I thought - this screensaver is starting a different executable on it's own. That's what takes the -help option, NOT the screensaver! I'll look at this more tomorrow, but when I start the underlying executable with the -help flag, I get this output. I think then, if I pass "fullscreen" to the executable, it'll work. In addition, it may (if it's configurable) be able to be used to get the graphics working from the manager. Not sure I'll do that one or not, since the screensaver is enough for a start.

3) Questions and Answers : Unix/Linux : Getting live graphics to display in graphical window? (Linux Mint) (Message 91397)

I check about every six months (since I started years ago) to see if there's an update to the package, but so far, no luck on graphics output.

UPDATE: I just tried the boinc-screensaver, and I can get output from that. See:
