(In reply to liulei from comment #0) > VGA monitor can be recognized, but can't be lighted up. What exactly do you mean by that? Also, dmesg has no debug information. Add drm.debug=0xe to your kernel command line and attach it again. Test 10 cycles with the latest drm-intel-nightly kernel(commit 4643c57c23dcee0ef150c580329482fb6a18ab9c)on BYT platform,VGA monitor can be light up normal.So,I think the bug could be closed.
