Comment 4 Keith Packard 2006-12-04 17:59:37 UTC
RandR structures weren't getting recreated on regen as they are currently
created in the PreInit function which isn't called at that time. Fixed it by
re-creating them at regen time in the ScreenInit function.

Comment 6 Eric Anholt 2006-12-08 00:20:13 UTC
This bug is about crashing of the X Server when the last application exits.  You
appear to be reporting a totally different bug, of the DRI not reinitializing
after server regeneration.  Re-closing -- please open a new bug if you aren't
experiencing the specific bug in this report.
