Any idea for this? so this is an optimus setup of some sort but now with amd + nvidia... i might imagine something goes wrong setting up randr maybe? simotek found his optimus setup required a forced refresh of randr info ... and e has that in it (otherwise edid info would not be populated right). check ~/.e-log.log - it will tell you what e is doing randr-wise and what it sees, but you should end up with some kind of screen. perhaps go back away from modesetting to amdgpu + nvidia? -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
