Ok, I also have A09 released 2014-06-26. The other thing I did was to install the latest Nvidia drivers in Windows, but I did not think this updates any firmware in the graphics card?
After that, I have almost not seen this issue anymore, but maybe once. ** Changed in: dell Status: Incomplete => Confirmed ** Changed in: hwe-next Status: Incomplete => New ** Changed in: oem-priority Status: Incomplete => New ** Changed in: nvidia-graphics-drivers-331 (Ubuntu) Status: Incomplete => Confirmed ** Changed in: nvidia-graphics-drivers-331-updates (Ubuntu) Status: Incomplete => Confirmed ** Changed in: xserver-xorg-video-nouveau (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1268151 Title: [Dell M4800] DPMS support broken, fails to wake up the monitor after putting it to sleep To manage notifications about this bug go to: https://bugs.launchpad.net/dell/+bug/1268151/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
