Unfortunately, the chip sets in this laptop have severe issues with the open source driver - one of the reasons I am running (x)ubuntu 12.04 beta is that it is currently the only distribution I know of where the restricted fglrx driver will install, allowing me access to the ATI control panel, with which I can change the "Dual Graphics" mode to use the low power AMD chip instead of the high power AMD chip also present. The open source driver, if it works at all, will default to the high power version intended for 3D games, even for desktop use, with no choice available to switch the graphics to the "normal" chip. That causes such an amount of heat that running the laptop with it would, I fear, eventually cause damage.
If I have understood correctly, these chip sets need some ATI-specific firmware to show even the 2D graphics, supplied by the linux-firmware packages, even with the open source driver. And all or most kernels before 3.3 suffered from various clashes between kernel/firmware/open source driver/closed source driver versions... causing a failure to boot and/or a failure of getting the graphics started. The Ubuntu kernel mainline builds page cautions that binary drivers will not be available, so I would assume trying to boot with one of those kernels would fail automatically. Do you know if the (x)ubuntu 12.04 beta linux-firmware is compatible and/or would be used with the latest mainline kernel? If it is, I could try to install the latest mainline kernel and see what happens with it.. or, if it is not compatible, what should I do to provide access to the firmware to the latest mainline kernel? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/981748 Title: Kernel Oops - BUG: unable to handle kernel paging request at ffffffffa0e2feb0; RIP: 0010:[<ffffffff81090b03>] [<ffffffff81090b03>] blocking_notifier_chain_register+0x33/0xb0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981748/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
