Hello,

No KDE game will run on my machine.
For more information. See http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/164742

A workaround is described here (http://mail.kde.org/pipermail/kde-freebsd/2011-November/012199.html)

Thanks,
It worked. Now I hope someone finds a real solution to the problem.

What makes setting the kern.ipc.shm_allow_removed sysctl to 1 not a real solution?

Hello,

Because OH speeks about a work-around and im my opinion a work around is never a real solution but a temporarily solution until a real solution is found.

I'm still not sure why that's considered a "workaround" in the first place. It fixes the problem. Seems like a solution to me.

Setting kern.ipc.shm_allow_removed to 1 is iirc a security risk and a performance gain. Users should be able to set it based upon their own performance / security needs, not because a game (or other piece of KDE4-software) requires it.

If you're the only user on the (desktop)-machine (which is a safe assumption if it's running games/kdegames4) the security risk is negligable.

A real fix has just been committed (to x11-toolkits/qt4-gui). After installing you can reset your kern.ipc.shm_allow_removed.

Hello, I just installed (re-installed it) and it does not work for me. But I don't get it when you say reset your "kern.ipc.shm_allow_removed". Can you explain that a little more please. Thanks.

Please double-check you have
qt4-gui-4.7.4_1 and not
qt4-gui-4.7.4

Setting kern.ipc.shm_allow_removed to 1 one was suggested as a workaround to get the games (and astro/marble) to work (see the link in the second post in this thread).

You can check wether you are affected by this particular problem by doing the following in a terminal:

$ su
# sysctl kern.ipc.shm_allow_removed=1


If the games then work for you, this problem is more persistent than we thought. If the games still won't work for you, then your problem is something else entirely.

Thanks a lot, is fixed now.
