Description Ognjen Maric 2016-03-16 12:59:41 UTC
External monitors attached through an HDMI->VGA adapter on my Lenovo Thinkpad Yoga do not work anymore. xrandr detects that a device has been connected, but it the correct device name is not displayed anymore, and xrandr fails to detect the correct resolutions offered. I have not tried doing this without the adapter, as I only have a funny mini-HDMI port.

This refers to xf86-video-intel 1:2.99.917+560+gd167280 and xorg-server 1.18.1.
This is a regression from xf86-video-intel-1:2.99.917+478+gdf72bc5 and xorg-server-1.17.4, the latest version of xorg 1.17 available for my distro (Arch Linux). None of the xorg-server-1.18 versions and compatible intel drivers appear to work. Downgrading the packages solves the problem. However, it also breaks my keyboard, so if you would like me to compare outputs of some commands under the new and old versions, any hints on how to enable the keyboard again would be very helpful.

Feels like a kernel problem, which kernels have you tried, which work, which don't? Can you bisect?

timeout - marking as resolved+worksforme. Please reopen with debug data from the latest kernel - see https://01.org/linuxgraphics/documentation/how-report-bugs.
