Is there anything helpful (commands, logs, etc) I can attach that would be helpful? What I don't understand is why it boots the live CD ok, but hard hangs post install. I am just a bit hesitant to install/remove the GPU too many times, it is a bear to get in and I worry about damaging the motherboard, socket or GPU but if you have a useful non-destructive experiment I could do that would help debug this I am willing to reinstall and give it a try. I remember the last message being printed before the hard hang was a radeon ACPI error message, and not a RadeonHD, so I am reclassifying it - sorry about that. When I get a chance I will reboot into the live CD and confirm this. The installer picks the driver automagically - There isn't any alternatives offered, except for click to install fglrx unless there is some hidden advanced settings I am unaware of. https://help.ubuntu.com/community/RadeonDriver The Ubuntu live CD booted just fine with only one CPU and no closed source drivers. I did not need "nomodeset" for the single GPU - the installer and post install first boot went just fine, and I was able to subsequently able to subsequently install fglrx. It was only when I added a second GPU that things turned evil, and the open source driver failed to work. I concur with your comments about it probably not being tested with dual HD5970s. (It has been tested now, by me!) But AMD now has crossfire settings on their Linux catalyst drivers, so it is a configuration they support or at least plan on supporting soon. I have seen I think I was one of the first on the planet outside of AMD to try running even a single HD5970 under linux back in March, (Needed for X-Plane9 to run on max settings at 2590x1600) and I filed a bug for it: http://www.mail-archive.com/[email protected]/msg50573.html Fortunately things were fixed just in time for Ubuntu 10.04, and there are more than a few other Linux users running with this card. The drivers seem stable as long as you are using only one card at a time. Others are trying to work with multiple HD5970s under Linux without much luck either: http://forums.amd.com/forum/messageview.cfm?catid=390&threadid=137959 but clearly some other cards have been working under crossfire for a long time: http://www.phoronix.com/scan.php?page=article&item=amd_crossfire_linux&num=1 -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
