Q: screen interference since upgrading to OSX 10.9, MacBook Pro

Nov 20, 2013 12:03 PMby Linc Davis,HelpfulYou have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:
MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
Print the support page linked above and bring it with you.
Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair. The model was discontinued in February 2011, so the replacement program will be ending quite soon.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Sometimes the replacement part is also defective, so be prepared for that possibility.If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.*An SSD doesn't need to be zeroed. -
Dec 11, 2013 1:34 AMby Ragged Apple,Since making my original post about the screen corruption I have followed a number of similar posts by people experiencing the identical problem. My conclusion is this is a problem which Apple will have to provide a solution for. Whether a patch or update or what - it is wasting peoples time to ask them to attend a Genius appointment or to reinstall Mavericks. The online evidence is that neither of these actions has provided a permanent solution.
The most likely problem area - as detailed by Frank23456 :
I have done this with, so far, success. I have also installed 8GB of memory, replacing the original 4GB.
I'm keeping my fingers crossed - but please, come on Apple, this is not the time to go silent on a problem causing so many users grief.

Dec 11, 2013 5:04 AMby jvinegar,The problem is the Automatic Graphics Switching. (As posted in Frank23456: )
Head over to your System Preferences > Energy Saver, and unselect "Automatic graphics Switching". I find when I toggle that it will solve the problem.
It's not a permanent fix, but it clears the scramble. This will have to do until Apple provides a permanent solution.

I don't think he's ignoring you, it's just that your post mentions the Automatics Graphics Switching at the end of your post and it's such a small blurb it's easy enough to miss. Heck I did until about 2 minutes ago when I was in middle of writing a response about how you missed his point... then realized you actually did discuss the autographics switching at the end.
If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
It's also not entirely clear if it would work... only that it's your 'suggestion'. While others have posted a 'clear'
Head over to your System Preferences > Energy Saver, and unselect "Automatic graphics Switching". When toggled (unselected) that it will solve the problem.
I'm on a MBP17", I don't suppose you know if there's any chance Apple Genius Bar can help me?
