Hrm, ok... So, vt switching on the I915 that I'm using to test(which doesn't support msi) works pretty much perfectly. Console is not corrupted, (unless I've restarted X at least once). Shutdown/reboot from gnome also works as expected. I did most of the msi development on an i965gm, which did support msi and vt switch also worked with msi at that time. Restart was problematic on the 965 then as well, which I believed to be an agp, or agp/drm interaction issue. So, unless some of the recent changes other than msi, have broken 965, they should be mostly working ok as long as you don't restart. The g31 and g45 are slightly different and all of my work for those has been based on what Intel has released for linux and the small amount of documentation that is available at this point. BTW, you debug output looks strange to me, did you also capture the drm debug log from hw.dri.0.debug=3D1? robert. > -Brandon --=20 Robert Noland <rnoland@FreeBSD.org> FreeBSD --=-atBWlYA2WXu5JHSlsvNh Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEABECAAYFAknMeJsACgkQM4TrQ4qfRON8RACfdIbtTDMyiaAoc34v6u+NIY/a Y7YAniEXM4GRQxJXQd6IBkITE2nJwbLw =7O3e -----END PGP SIGNATURE----- --=-atBWlYA2WXu5JHSlsvNh--
