Re: [Kernel-packages] [Bug 1221790] Re: Screen brightness is maximum upon fresh boot
I did upgrade the BIOS a few weeks ago when I was running 13.10. Unfortunately, this didn't change anything. I am now running 14.04 with the latest apt-get and the results are the same. What happened? Upon cold boot or restart, the screen brightness is set to maximum even if my setting wasn't. Output of the command sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date G6ET99WW (2.59 ) 11/19/2013 One thing I noticed is that when the machine boots and the lenovo logo is displayed, the screen brightness is set to maximum, which leads to believe that UEFI runtime services may not be setting the brightness variable properly so it isn't persistent. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1221790 Title: 8086:0166 [ThinkPad X1 Carbon] Screen brightness is maximum upon fresh boot Status in “linux” package in Ubuntu: Incomplete Bug description: Hello, Trouble: Everytime I restart or cold boot my Thinkpad X1 laptop, my screen brightness is set to maximum.

Re: [Kernel-packages] [Bug 1221790] Re: Screen brightness is maximum upon fresh boot
I just confirmed that the problem continue to exist using Linux X1 3.11.0-8-generic #15-Ubuntu kernel. The 13.10 system is updated as of 2013.09.21.

Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We are approaching release and would like to confirm if this bug is still present. Please test again with the latest development kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get dist-upgrade If the bug still exists, change the bug status from Incomplete to Confirmed.

Re: [Kernel-packages] [Bug 1221790] Re: Screen brightness is maximum upon fresh boot
This didn't used to happen. I believe it started with the 3.11 kernel since there is new code in that area. I will try installing 3.10 and some early 3.11 RCs and see where I land. I know where to get the earlier kernel packages (kernel team PPA) but how do I interrupt the boot process to tell ubuntu to run an older release. Everything is masked by the Ubuntu logo boot now.

Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem. ** Changed in: linux (Ubuntu) Importance: Undecided = Medium -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1221790 Title: Screen brightness is maximum upon fresh boot Status in “linux” package in Ubuntu: Confirmed Bug description: Hello, Trouble: Everytime I restart or cold boot my Thinkpad X1 laptop, my screen brightness is set to maximum.
