Blank screen after rotating the display in Yosemite (MacBook Pro Late 2013)
Hi,
after installing Yosemite on my MacBook Pro 15" Late 2013 I have trouble rotating it's screen. After I launch Preferences and click Displays while pressing alt and command keys I see the list of possible orientations available.
If I now select 270° the screen immediately goes black. To be clear: The display is not turned off like when the MacBook sleeps. It's still lit, but only shows a black screen. After turning the MacBook off by pressing and holding the power button I can boot and voilà, the screen is perfectly normal, showing everything rotated at 270°. If I reset to Landscape from there (i. e. 0°), I have no problem at all, everything still works. Setting it back to 270° again lets the screen go black again.
I have an installation of Mavericks at my primary partition and it has no problems at all with rotation. Is this a known bug or can anyone confirm this behaviour?
As a hint for others suffering the same problem: You can get around the hard reset by pressing shift-comand-q followed by enter key. This logs your user out of the system and gets you back to the login screen. This obviously kind of reinitializes the UI. After that, the display's rotation is working and you just have to login again.
Even if this is some kind of workaround it would still be much more convenient not requiring this workaround.
Thanks in advance,
Oliver
