Hi all,

I'm running KDE 4 under FreeBSD 9-stable (installed via the kde4 meta-port). Everything was working fine until I had an O/S crash and some files were deleted during the fsck afterwards. Most things still work, but not any of the KDE games. They all come up with a completely empty window. For example, KPatience has a title bar saying KPatience and with the usual border and decorations, but otherwise completely empty. The same thing happens for all the other KDE games I've tried (KSudoku, KSquares, KSnake etc.). I've tried reinstalling the kgames port and I've reinstalled all of kde4. I've tried creating a new user, logging on as them, and running the games - same thing.

If I run kpat from the command line, I get:

Code: Select all

QPixmap::handle(): Pixmap is not an X11 class pixmap

The last four lines get repeated a hundred or so times.

Does anybody please have any suggestions.

Thanks,

It is probable that essential *ui.rc or SVG based themes (or any of their components) have been deleted from your system. It is probably best to fully reinstall KDE Games at this point to ensure a fully consistent installation.

Thanks for replying. I've already tried reinstalling kdegames. In fact I've tried reinstalling all of KDE. I'll start looking for the files you mentioned.

Thanks,
Graham

Another thing to try reinstalling would be kde-runtime and kdelibs. I guess you use other KDE Applications and they are unaffected however?

I got the same errors, this thread viewtopic.php?f=21&t=100392&p=216309#p216309 can be merge?

I think *ui.rc were there, located at /usr/local/kde4/share/apps, and I just been force to reinstall everything using portupgrade -aR (after the upgrade then those games did'nt work). Do you think I need to reinstall all KDE4 again ?

Given that Knights uses the same similar infrastructure, they are probably related, especially given that you both use FreeBSD...

Please continue the discussion on the other thread.

I just found the solution- it's a FreeBSD MIT-SHM problem. It must have been purely coincidental that it happened when I had the crash. It's now (as of 2012-03-13) fixed in 9-Stable. Alternatively, you can do "sysctl kern.ipc.shm_allow_removed=1" in older versions.

Yes I confirmed it was fixed in both 8.2 AMD64 release stable and 9.0 AMD64 release after I upgraded ports 3 days back.

I've marked this as solved. Odd how that could have caused the breakage... it explains the X Errors though (I am surprised that KSharedDataCache wasn't complaining as well)
