--- Comment #64 from Paul Menzel paulepanter@users.sourceforge.net --- (In reply to Christian Aßfalg from comment #63)
I think / guess that I am having the same issues. I've got the same laptop, running Arch Linux. Mostly, I've been using the proprietary catalyst driver, since I never got the free driver working. The proprietary is working fine.
Then you had more luck than I did. What FGLRX version do you use?
What is the issue here? You've been playing with timings for the physical link to the internal panel? Is it so frickly? What would you need to fix the issue? How can I help?
I was just told to play with the timings, but I actually have no idea anymore, sorry. Also I do not use that laptop anymore, so I have no easy way to test that. Hopefully the developers will be able to help you.
What Linux kernel versions did you try?
