[Kernel-packages] [Bug 935778] Re: Toshiba Tecra R840 - brightness controls work on first boot, but do nothing after suspend/resume
James Troup, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- 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/935778 Title: Toshiba Tecra R840 - brightness controls work on first boot, but do nothing after suspend/resume Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Incomplete Status in Debian GNU/Linux: Confirmed Status in Fedora: Unknown Status in openSUSE: Confirmed Bug description: Overview - This bug affects many Toshiba laptops including R700, R705, R800, R830, R835, R840, R850, Z930 models - please update this description if your model is also affected, but make sure the symptoms match exactly. The symptoms are that brightness control operates normally when the system is first booted, but after a suspend-to-RAM and resume cycle the brightness controls have no effect. After a normal reboot, or hibernate resume cycle, the brightness controls operate normally again. This bug is tracked for the kernel at: http://bugzilla.kernel.org/show_bug.cgi?id=21012 And for Debian at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=599768 Please try to keep all info together and pass any progress to the upstream trackers. Original report for #935778 follows: On my Toshiba R840, the brightness controls work fine on first boot, but do nothing after suspend/resume. This is particularly frustrating if I suspend with the screen at all dimmed, because once I resume, I have no way of increasing the brightness short of a reboot.
