Thats nice :) Ok, from your logs I was not able to see anything wrong. X server does not error exit and Prime seems to be working in DRM ... Lets try one more thing: Enable all debug in DRM (drm.debug=0x3f) and try to correlate the log with the actions. i.e. [boot] [log] [x start] [log] [xclock start] [log] [glmark2-es2 start] [log] If that does not give any more info then maybe someone with better understanding of etnaviv, UDL and X can help (maybe cc X devel list also ...)
