Description of problem:
External display is not receiving any input from the system with 3.8.3-201.fc18.x86_64. I've tried both vga/dvi inputs and tried to connect display trough dock and directly to the laptop.
So far xrandr and gnome-config-display sees the second display but as I said the display itself does not detect and input at all. I've tried to switch display layouts with fn+f7 but so far I never got to a point that display panel would display anything.
workaround is to use older kernel (3.8.2-206.fc18.x86_64) which works.
Version-Release number of selected component (if applicable):
rpm -q xorg-x11-drv-intel kernel xorg-x11-server-Xorg
kernel-3.8.3-201.fc18.x86_64 (does not work)
Steps to Reproduce:
1. boot t400 with kernel-3.8.3-201.fc18.x86_64
2. connect external display to laptop
3. configure any display layout which is using external display
external display does not receive any input (internal display works)
external display should work
[lkocman@localhost ~]$ lspci -nn | grep VGA
00:02.0 VGA compatible controller : Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)
using older kernel solves the problem
I' experiencing the same feature on a Lenovo X200 with an Ultrabase using
This one is fine, at least on my X200! Thanks!
Works for me (t400). Lubos
