Well, the DRI is supposed to be reinitialized by X from EnterVT() which is called when the system restores the VC of the server on wakeup from sleep... However, I've been having issue with that code. In fact, it's possible that your problem is related to the problems I'm trying to fix of MC_FB_LOCATION and MC_AGP_LOCATION being set to crap and overwritten in potentially conflicting ways between the server and the DRM (among others). > P.S.
