Created attachment 97891 [details] xserver logs showing the relevant parts of both xservers This crash happened for me when I ran 2 xservers in valgrind (to slow it down and to make races more likely) on vt 7 and 8 and did a quick change between them: "chvt 8; chvt 7; chvt 8; chvt 7; chvt 8; chvt 7" But for a more generic case: while chvt 7; do chvt 8; done
Care to encapsulate that into a test script? I think you used: #/bin/sh X -novtswitch vt7 :0 & X -novtswitch vt8 :1 & while chvt 7 ; do chvt 8; done
Hm what seems to happen with that testcase is that chvt times out. Poking it by starting a x client on both server kills one. So the easiest testcase would be: #!/bin/sh Xorg -novtswitch vt7 :0 & Xorg -novtswitch vt8 :1 & sleep 5 DISPLAY=:0 xeyes & p1=$! DISPLAY=:1 xeyes & p2=$! (sleep 20; kill $p1 $p2) & chvt 8; chvt 7; chvt 8; chvt 7; chvt 8; chvt 7
