If you want to send me another debug trace, I'll see if I can tell what is going on now... Also, please send me a copy of your xorg.conf. > How to make sure that this is really drm problem and not i915, Xorg, > mesa-ports that need recompiling? If you are using current ports tree, then nothing should need rebuilding that I can think of. I have been using git libdrm and xf86-video-intel driver, but what is in ports now should be fine I think. The updated libdrm should only be required to get the new vblank code to allow it to disable vblank interrupts. There is a bug which prevents vblanks irqs from being disabled after a vt switch, but it shouldn't have a real impact on functionality. robert. --=-3CDwYmdW9Y5KK4SDA5W6 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEABECAAYFAki4G90ACgkQM4TrQ4qfROMykwCePGdCdDAMaGl0fotSqfAMJRoG 288An0q2s+mvaBVygJ5VO6H4ag5yO6Cc =I/Ez -----END PGP SIGNATURE----- --=-3CDwYmdW9Y5KK4SDA5W6--
