dmesg 3.10.7
When attaching a monitor to the VGA port of my Thinkpad X220i and playing a
fullscreen video with VLC (with hardware accel turned on) the GPU hangs and vlc
either freezes or simply shows a black video. This used to work with 3.7, but
starting with commit 7739c33ba48174204b24c1b867b455318e752787 ("drm/i915: add
DP support to intel_ddi_enable_pipe_func") fullscreen video on VGA is broken
for me.
System environment:
distribution: Gentoo Linux
chipset: Sandy Bridge
architecture: 64bit
xf86-video-intel: 2.20.13
xserver: 1.13.4
mesa: 9.1.2
libdrm: 2.4.45
kernel: 3.10.7
machine: Thinkpad X220i 4290-W1A</pre>
