[Kernel-packages] [Bug 1485246] Re: Backlight issue - Samsung Chronos 7 (model - NP770Z5E)
The issue occurred on a fresh install of Ubuntu 15.04 but as I was previously running 14.04, you could describe it as an upgrade (though it was not through the upgrade mechanism). There was certainly a previous kernel version where this was not causing a problem, but I am unable to tell you which it was having now wiped out the previous install with the fresh install. I will try the upstream kernel and report back. Thanks for your feedback/input. -- 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/1485246 Title: Backlight issue - Samsung Chronos 7 (model - NP770Z5E) Status in linux package in Ubuntu: Incomplete Bug description: Control of screen backlight is broken with a default clean install of Ubuntu 15.04 on my Samsung Series 7 Laptop (NP770Z5E).

[Kernel-packages] [Bug 1485246] Re: Backlight issue - Samsung Chronos 7 (model - NP770Z5E)
Right, so I have re-tested having installed the 4.2.0-040200rc7-generic kernel. The behaviour seems to be identical to the stock Ubuntu 15.04 kernel. A few things I have noticed having carried out several reboots and suspends in the process of testing this. These apply to both the stock kernel and the 4.2 kernel: With kernel parameter acpi_backlight=vendor 1. On first boot the brightness of the screen is about 60% brightness and attempts to change the brightness setting via the hotkeys causes the brightness level notification to flicker and the brightness level cannot be altered 2. After a suspend the brightness returns to about 100% and using the hotkeys may then work (i.e brightness controls have been properly restored). This occurs on about 2 in 3 wakes from suspend, the other 1 in 3 the brighness is 100% but control over brightness still non-functional with no acpi_backlight kernel param 1. The initial boot brightness is approximately the same as above. Attempts to change this successfully move the brightness level in the indicator, but have no impact on the actual screen brighness. 2. wake from suspend results in the 100% brightness as above, but no control of screen brightness still Not sure if any of that actually helps any... Let me know if I can extract any further useful information to help with debugging. ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed ** Tags added: kernel-bug-exists-upstream -- 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/1485246 Title: Backlight issue - Samsung Chronos 7 (model - NP770Z5E) Status in linux package in Ubuntu: Confirmed Bug description: Control of screen backlight is broken with a default clean install of Ubuntu 15.04 on my Samsung Series 7 Laptop (NP770Z5E).
