On the previous 12.04 (tested for a short time), the problem was not happening. The point is that with the release 12.04, there was a serious over heating problem with the open drivers.
With the property AMD drivers (better if version > 14.6, previous drivers gave problem to the brightness regulation) the problem is not present. But the official AMD driver has a really bad performances. With the open driver the battery has a duration of 3:50 h. With the property driver 1:20 h. I also tried the last 14.10 beta version, the problem is not solved. Can you please explain how to apply this fix: https://bugzilla.kernel.org/show_bug.cgi?id=76761#c3 Thank you again for your time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: [Samsung NP535U4X-S01TH] Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1283938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
