I have the exact same laptop as the OP. I have the same problem. This seems to be a problem since Linux kernel 3.0. I'm using Ubuntu 64 bit version.
I've posted the problem and some of the things I've tried here: http://phoronix.com/forums/showthread.php?60883-AMD-A6-3400M-not- working-on-Linux-kernel-3.0 On booting Ubuntu 11.10 live image for beta1, beta2 and final the display does not light up. I cannot even install using the Live CD. I will try the method suggested by Glome (i.e upgrading 11.04 to 11.10). On Ubuntu 11.04, tried compiling vanilla kernel 3.0.4 from kernel.org and the same problem occured. Even with a fresh copy of Ubuntu 11.04, compiled kernel 3.1.1 from kernel.org, used xorg-edgers repository and copied firmware for both integrated and discrete cards to /lib/firmware/radeon and /lib/firmware/radeon/(kernel-version) directories and it STILL doesn't work. Some people have had success with Gentoo and other distros. The same problem exists in Fedora as well and it seems to be something in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/825777 Title: Display will not turn on in Oneiric with Llano APUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/825777/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
