Want to seek your opinions on the bug descrived in these links. Basically, users of AMD videocards can’t use fglrx with more than 3GB RAM on intel latest chipsets on 64-bit distros. Black screen and total lockup when trying to start x.
There is something about MTRR tables I can’t quite understand. But nobody is saying what is the cause, what needs to be fixed.
My system is
Core 2 Duo E8200
Gigabyte EX38-DS5
4GB DDR2-1066
ATI Radeon 3870
OpenSuse 11.0 RC1 x64
Hoping for a good solution that doesn’t involve halving my memory or sacrificing performance. Having hardware acceleration would be nice.
I did not say it was an OpenSUSE bug, I said it was a kernel bug. The proper way to report kernel bugs associated with a Novell product is via bugzilla.
this is not opensuse bug nor kernel bug. This is hardware/BIOS limitation. A lot of cheap (desktop) mobos can’t cope with >3GB RAM even though manufacturers claim otherwise. In fact these mobos that will not crash still have exactly the same problem.
You have the following options:
decrease video aperture (BIOS)
decrease video card RAM
use no more than 3GB of RAM
get BIOS update from your mobo manufacturer
even though your problem may go away it is still not fixed and kernel has nothing to do withe the problem.
Just to clarify, though, the devs can’t support closed drivers. It’s really an AMD issue, and not a linux/openSUSE issue.
Having said that, they know that there are many users with closed source drivers, so will do what they can to assist. But the onus isn’t on the devs to address the issue.
