[debian-yeeloong-project] Bug#624695: xserver-xorg-video-siliconmotion: No VGA output on Lemote Yeeloong.

[Michael Dorrington]

Package: xserver-xorg-video-siliconmotion
Version: 1:1.7.3-2
Severity: normal
Tags: patch
User: debian-yeeloong-project at lists.alioth.debian.org
Usertags: yeeloong
X-Debbugs-CC: debian-yeeloong-project at lists.alioth.debian.org

After using the patch to xorg-server detailed in #594684
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=594684> and the
include xorg.conf for help, X works on the attached screen (LVDS) of the
Lemote Yeeloong. However, the VGA output under X does not work. Further,
under a virtual console the VGA output does work.

details several patches including
http://www.bjlx.org.cn/loongson2f/squeeze/xserver-xorg-video-siliconmotion/98_sm712_CRT_enable.diff
I guess that 'CRT' in the name is referring to external monitor output
(the VGA). I am not sure of the correctness of the patch, it could
certainly do with being reformatted. But applying the patch results in
VGA output under X working as expected.

Regards,
Mike.
