Spring freezing (no sound, no screen updates) ingame.

[Scram80]

Hi... I'm using Spring on linux (amd64, 64bit Spring compiled from 74.b3 branch in svn)

from time to time spring completely locks up - i've got no clue what could be the cause.

I compiled spring with debugging infos, attached gdb to get the bt when it is locked up:

i'm not perfectly sure...
from what i can guess looking at the Bt, something goes wrong when freeing that CommandDescription and SDL insists on waiting for some Thread in the Signal handler (i assume signal 11)

- but i doubt theres something wrong with the object.

Any idea what could be the cause of this 'crash' ?

[Scram80]

It's not reproducible by executing the demo of that game.. but it might be that the final frame(s) haven't been written to the file by the time of the crash?

apart from that:

OpenGL renderer string: GeForce 6100 nForce 430/PCI/SSE2
OpenGL version string: 2.1.0 NVIDIA 96.31

[very_bad_soldier]

Very interesting. A friend of mine has a similar problem. But with the regular Windows version.

In midgame all graphics freezes but he is still connected to the server and can still chat. But his entire screen is still. He is also able to give away his stuff to a teammate.

I dont have a clue whats the cause of this. But its very annoying.

[Scram80]

No, thats not that similar... in my case the screen absolutely freezes - no updates are done anymore.

If i switch to desktop and back to spring, the spring screen will remain completely black. And i didn't suceed in issueing commands...

[Relative]

I get the same thing as you Scram80, but I always thought it was because of the crappy linux ATI drivers so I never bothered to report.

Also, how do you "switch to desktop and back to spring"? I didn't think minimising a full screen game was possible with x-server. I would love to know how you can do it.

[Scram80]

Oh. i let spring run in windowed mode and tell the window manager to enlarge it to fullscreen (not maximising but fullscreen)

in gnome (both with metacity and beryl) you can configure it to a keybinding (from System|Settings|Key Combinations) - so i press ctrl+enter when spring loads up, the window frame vanishes and i get fullscreen spring... But still i can do alt-tab and switch virtual desktop.

KDE should be able to do the same

Thanks, I didn't know you could do that.

Edit:I works great, thanks again.

-. different stacktrace though this time., same simptoms.

Might it be an SDL issue?
