关于默认启用kms的问题

最近 新内核默认启用kms
在我的本本上 开机一段时间后 x死掉
startx 也不行 只能重启

但当禁用kms 就干脆进不了x了 郁闷中

我的显卡是
Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller

你算好的，我845在32上连kms都认错分辨率了...至今是2.6.31.9...

几个星期前刚装好的ARCH,偶尔莫明其妙的鼠标就定住了,键盘上怎么按都没反应.死机了,只有重启,次数多了就觉得不对劲了,看了下/var/log上的某个文件(忘记是哪个)看到有几行有这几个关键词 fb comflict vesa ,我就奇怪了我A卡没装xf86-video-vesa呀,查一下还真有,把vesa卸载了以为没事了,隔了不久又是同样的现象,google了好久,原来fb就是framebuffer.再查了下ARCHWIKI,找到KMS那段,然后禁用之，爽了。

Next issue is problems with Intel KMS. The 2.6.32 kernel contains
powermanagement features for intel. These new features are utilized by
the driver I uploaded to testing last weekend on hardware that supports
it. However, this causes GPU lockups, requiring a reboot now and then.
This was reverted in 2.6.33, so we should also revert this. A patch has
been posted here:
http://patchwork.kernel.org/patch/67768/

This patch is also committed to the drm-intel git tree, maybe it's
easier to fetch the patch from git.kernel.org.

可能是这个导致的?
