Doing things in this order essentially forces yet another full panel power sequence delay at this point. Hrm. I'll have to test again when I get a chance, but perhaps we can turn the sink DPMS on before we turn the panel power off. > Oh missed the vdd on, which is in this path too...

Right, I'll try doing the sink_dpms before turning the panel off; that should work just fine, and should make the sequence a bit faster. =2D-=20 keith.packard@intel.com --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUBTrMcvTYtFsjWk68qAQgeTg//XV2CYNnT8QLFi/uuHTCiAPcHuLb2alXx AAwoObA+frVRgdQvX6HPCMxRiVhfMnL+prhiwo9aQiEdjR65yt0aZg9qfSGbtOaj 7B/e4TGlVXbiyosQlxxZ8UiWlDuFUv5uKvnqiRZTA0ZSanK8XalHiaLz7ydO/e9T 5CdxsEakaS9jvp19+rjB+Uc2hadITkGV5WWPx5M8BoauDyL7zgxx9MrjB6+Y+j/o M5uwNaI2w6FAmvRs8GHXrEhNHNADqN+Hq4JCbXwdvMABgdTO/JhDY+poJUUYV4ai oWI8X/GHzyqOO//B2tGbj2j1QXDMkWr0mlP3wTf+DVFnlNfR4SceaYPQSHtnyNfu QZQY5T3FCUudqQjIAvFMqlQIxCvYa6PrZ4hCLma244IL6yiM7XiCqtQaG6hQQsT8 c3YUOMIzCg5krU0B29QwoUzAkFfcbEjeOjirFN8cMu9NgEMC/rYR7vF8oDzkHZyj 7/m1Ev03YL7Kfvfu4U/u6gsd8Ch9qq8UhshLI1jA4lEeBeYV0sNb5AxHEge2H/nf xwa3UjZEVFBWTnAp96LUxz7PJ5SozRgCtKTJlFDXRICz0PdvQJJVypU2/Lp5KhHV 1tU5tqzjYEeMbVTAnZ+d6ViUYTtH65SGlA3WuVvm9CEhXnN2xMYIMHU2j9tRG7Pd /c1Z+ldfixg= =sXZQ -----END PGP SIGNATURE----- --=-=-=--
