Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.8 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Since the fglrx driver is an out-of-tree driver I have marked this bug report as "kernel-unable-to-test-upstream".

[penalvch (penalvch)]

Bart Van Assche, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (1.18). If you update to this, does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

[Bart Van Assche (bart-vanassche)]

Since I reported this bug I have switched from the fglrx driver to the in-tree Radeon driver because the fglrx driver was causing too much trouble. I have also switched from GNOME 3 to xfce to get rid of Compiz. After these two changes Ubuntu is running reliably on my laptop.
