Interesting. The manager crashing has something to do with permissions to use the display. If I su to boinc's account and then show graphics (with E@H as I don't have any P@H right now) the graphics display properly.

So two things to try with 'xhost' are:

xhost +local:boinc
xhost +local:

The first grants the boinc user permission to open a window in your X11 session. The second grants any local user that permission.

You don't want to use `xhost +` by itself because it also allows non-local (ie. network) connections and then you can get sniffed or other troubles.


No luck. I tested with E@H to remove the factor of the cube graphics app crashing. In both cases, the manager crashes, albeit with different stack dumps.

And the graphics app when run under my account crashes as well.

Tomorrow night I'll update to the latest alpha build of the CC/Manager and see if that makes a difference.

And FWIW, the xphoon I downloaded did work. It's hidden under my desktop wallpaper. I could see it flash by when I locked my desktop.

Happy Birthday Little Miss Amanda!

You're doing such a great job! And the same for Mom and Dad.

I actually don't know if it works with Gnome or KDE, as I use "Classic" X.

But if it didn't bomb with SIGSEGV then it probably ran okay.


It didn't bomb (nothing printed out), but nothing changed on my desktop.

I'm using KDE 4.

In the download area (here) you will find an X11 program called 'xphoon' which I built from source on 32 bit Fedora 10. It does not use BOINC or OpenGL. Please try that and see if it works on your 64 bit machine.


Nada.

After doing a `chmod +x` and running it, I get nothing. Just dumped back to the command prompt.

Also, Eric,

I know it's possible to run under a debugger (gdb??) but I've only done it once before with someone holding my hand. Is that something that may help?

Kathryn, did you try to run cube_graphics "standalone" using your own account, not the boinc account? Can you also try the Einstein graphics (you'll find it in the slot). If you run these under /tmp then you should be able to get the stderr output files to see what goes wrong.

If it's a problem with opening the X11 display then it's likely a bug in X11 not in BOINC. But to test that idea I could compile a non-BOINC graphics program on my 32 bit machine and see if it will run on your 64 bit machine or if it crashes with the same error.


Using my own account, cube still crashes.

However, E@H works fine. The star sphere starts right up after the expected message about running standalone

[kathryn@Nova tmp]$ ./einstein_S5R6_1.01_graphics_i686-pc-linux-gnu
Can't open init data file - running in standalone mode

Except that I built it on a 32 bit machine, and you have a 64 bit machine.
The SIGSEGV suggests a real error, not X11 access controls. Do you have
all the libraries installed required to be able to run 32 bit applications?


AFAIK, yes. The ia32 libs being installed have never been a problem on Fedora. I can't think of a 32 bit BOINC app that hasn't run.

However, as always, I'm willing to check (and learn). What do I need to check for? I posted the output of ldd in the other thread if that helps.
