Also Confirmed - vendor issue, not Ubuntu - BIOS upgrade fixed brightness / suspend issues as well for me. Everything now works flawlessly.
A bit OT but in case others arrive here via google: the V5-122P BIOS updates *require* you to be running Windows 8 or newer. If you aren't dual booting into Windows, Acer forcing a Windows 8 binary in order to update the BIOS makes for a *very* bad day. FreeDOS does not work, not even WindowsPE on 32-bit works - it has to be Windows 8. Note being, when looking to buy hardware in the future not only will be googling linux compatability, but also checking to make sure the vendor is releasing BIOS patches which are easily installed using Linux as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315834 Title: 1002:983d [Acer Aspire V5-122P] Unable to adjust screen brightness using Radeon driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315834/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
