Comment 8 for bug 1392460

I have tried to upgrade the microcode. I rebooted into Windoze and ran the .exe. I see no difference in the value of microcode in /proc/cpuinfo, so I don't know that it took, but I did run the upgrade command, and sat there while it displayed its progress indicator.

I tried installing the 3.18 kernel but it failed, as I reported, and nobody has got back to me to suggest what I did wrong in the installation.

I have tried using the proprietary ATI driver. If I manually suspend the system and restart it does recover correctly with the proprietary driver. However with the proprietary driver if I close the lid and then reopen it the system does not resume at all. That is the only result is that I hear a "clunk" after the lid is opened, so obviously the BIOS recognized that the lid had opened, but there is no disk activity, and the keyboard is not enabled so the only recover is holding down the power button. With the open source driver the system reliably recovers on Ubuntu 14.10 kernel 3.16 (which it did not do on 14.4 with kernel 3.13) However the backlight is not turned on so I cannot do anything. I have been having that problem with the Xorg driver for several years now and when I ask their development group how to give the driver a kick to turn on the backlight their response is "the driver should do that for you." So I ask them again and every time the response is "the driver should do that for you". Why they cannot just add a command to turn the gd light on I do not understand. I guess they are purists.

I have even tried reformatting the partition and reinstalling 4.10 from scratch.

I really want to help you out by testing the problem but you have to tell me what to do, because I have tried to do everything you asked when I opened the problem and I have not heard from anyone since. I am really tired of having to leave my laptop open!

I cannot see any option for adding tags in the Launchpad user interface.
