CTRL+ALT+F1 etc too are not working to go to VT1 and others. Perhaps that is related to this problem ?

Comment 1 Vinay Khaitan 2006-02-13 08:27:57 UTC

Well, I got the solution. The XKB maps were not loaded actually.
The reason behind not loading that xorgconfig/xf86config actually writes that
Option "XkbRules"   "xorg"

Whereas xorg and xorg.xml files are not symlinked to base and base.lst unlike to xfree86 and xfree86.xml .
Hence it is not loaded. When changed to "xfree86" , it works fine.

So the solution is that, change xorgconfig to write only xfree86 instead of xorg.
OR, symlink the needed files!

Still, one bug is there, why does it segfault? Segfault is alwaya a bug despite of whatever is the condition. Hence, I leave this bug open.

Comment 2 Stefan Dirsch 2006-02-13 09:38:26 UTC

I've added the missing xorg rules sysmlinks. I could not reproduce the segfault. I don't even know, what a setxkmap command without any options should do.

The point to reproduce the segfault is that, try not to set xkbrules corectly, so that output of 
xprop -root | grep XKB
doesn't show _XKB_RULES_NAMES(STRING) .
Then try to setxkbmap argument_whatever_you_know .
