Public bug reported: Hello
This issue seems (from a Google search) to have many manifestations among DELL XPS users. My installation: 64bit Precise Pangolin on 64 bit XPS 15z Intel® Core™ i7-2640M. I am aware of the acpi=noirq situation, and follow the setup here https://wiki.ubuntu.com/HardwareSupport/Machines/Laptops/Dell/XPS/15z What happened: After an update this week, booting ended in a frozen black screen (exactly as has been reported before) What I did: Out of frustration, a complete new installation (12.04). This worked just fine. What happened next: update manager asked to do a kernel update. I obliged. My reward was the same black screen on reboot. What is currently working: GRUB booting with 3.2.0-29-generic (not 3.2.0-33-generic) My BIOS: is a little over a year old (A06). Until there is a method to update my BIOS within Ubuntu where I am fairly sure it isn't going to cause me untold grief (and there is clear Canonical supporting documentation), I prefer not to update my BIOS. This seems like a big one guys. I am aware of the challenges with NVIDIA etc. and feel it may be useful to at the very least clearly document this messy ACPI situation. I'm not sure I would have spent the money I did on this laptop knowing this (I'm not sure I would classify XPS 15z as 'working' with Ubuntu). Apologies if I've missed something very obvious.
