If a DRI client is running while you switch away, it will use these mappings (if the i8xx drivers are anything like the radeon drivers). De-initializing the DRI if possible when switching away and re-initializing it when switching back is what the infamous reinit patch for the radeon driver does. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast _______________________________________________ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
