[Bug 762855] Re: [sandybridge-m-gt2+] Display on external monitor (vga) is black on 13" MacBook Pro 8, 1 (x86_64)

 

Hi Dan,

You mentioned in your description specifically that the issue is seen as
of the 2011-04-16 nightly; by this comment do you mean to imply that
prior to 4-16 this issue is not reproducible?  If that is the case,
please tell me the most recent working version; I can then examine what
packages changed between that version and 4-16 and we can see if there
is a regression.

Otherwise, can you also test the following after reproducing the bug:

 xset dpms force on

If that works (heck, even if it doesn't) you may want to test this PPA,
which forces monitors to power on after making resolution changes:
