I have seen similar issues on my Acer C720 (haswell based). Could you run a test for me?
* comment out your kern.kms_console=0 line so the KMS console is enabled. * Instead of rebooting or halting from X, as root do a 'killall xdm' to kill X. This should return you to a KMS console. * Then try rebooting / shutting down from the KMS console. What I have noticed on my Acer is two things: First, sometimes when I start X up I get corruption and have to restart X to get rid of it. But if I kldload i915kms first and give the kms console time to initialize, and THEN start X up, I never get corruption. And Second, when I try to shutdown/reboot from X the laptop often locks up. But if I killall xdm (as root) to kill X and return to the KMS console, and then shutdown/reboot from the KMS console, it always works reliably. -Matt On Fri, Jul 31, 2015 at 11:49 PM, Todd Hoover <[email protected]> wrote: > My Asus (Intel N2830 @ 2.16GHz) needs kern.kms_console="0" now.
