Re: suspend/resume on Lenovo X1 (regression from reports on wiki)
Laura, according to your Xorg.log PCI device ID of your video card exactly matches mine 8086:0166:17aa:21f9, so it should work. It looks like versions of Xorg and Xorg Intel driver installed from packages are too old, and this is the biggest difference between your setup and mine. You are running Xorg 1.7.7. This is what I run: glebius@think:~:|>pkg info xorg-server xf86-video-intel xorg-server-1.12.4,1 xf86-video-intel-2.21.9 To get these packages you need to update your ports tree, put these lines into /etc/make.conf: WITH_NEW_XORG=yes WITH_KMS=yes , and reinstall xorg-server and xf86-video-intel from ports. You'd probably need to rebuild all xorg drivers like mouse and keyboard, to make them compatible with new server version. If this isn't enough I can send my xorg.conf and kernel config. But I hope default configs should be fine. Now bad news :) Last major Xorg update in ports, which happened couple of months ago, introduced a regression: xorg performs very slowly after resume. If the server process is restarted, then a new one performs okay. So this looks like xorg issue, not FreeBSD kernel problem.
