Are you running the current 3.0.0 kernel from testing? A kernel log with drm debug parameter set to 5 would be ideal; that will show all of the mode setting logic happening at resume time which is presumably not working. Two sessions, one working and one not working would make identifying trouble easier. You can set the drm debug parameter with a kernel command line option drm.debug=3D5 Second, the output of 'intel_reg_dumper', which doesn't appear to be packaged for debian yet. That's available from: git://anongit.freedesktop.org/git/xorg/app/intel-gpu-tools Again, having both working and non-working output makes it easy to identify any differences which may point out the problem. =2D-=20 keith.packard@intel.com --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iD8DBQFOeMQsQp8BWwlsTdMRAoJFAJ0XtfW3GkizVLHqt3YO4eF4dSQy7QCfWuvs C5wx+Mlc7Hiy+sNqG6sbF2I= =41Yu -----END PGP SIGNATURE----- --=-=-=-- --===============1175880196== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx --===============1175880196==--
