Description of problem: With an Nvidia video card in a Toshiba laptop running kernel 3.11.0-0.rc5.git6.1.fc20.x86_64 with the boot params of acpi_backlight=vendor acpi_osi=Linux I am unable to, in any way, adjust the backlight of my laptop. Manually changing /sys/class/backlight/toshiba/brightness has no effect. I have the following messages in dmesg relating to ACPI with this card: [ 15.084980] toshiba_acpi: Toshiba Laptop ACPI Extras version 0.19 [ 15.085429] ACPI Warning: 0x0000000000000428-0x000000000000042f SystemIO conflicts with Region \PMIO 1 (20130517/utaddress-251) [ 15.085453] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 15.085472] ACPI Warning: 0x00000000000011c0-0x00000000000011cf SystemIO conflicts with Region \GPIO 1 (20130517/utaddress-251) [ 15.085492] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 15.085509] ACPI Warning: 0x00000000000011b0-0x00000000000011bf SystemIO conflicts with Region \GPIO 1 (20130517/utaddress-251) [ 15.085528] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 15.085544] ACPI Warning: 0x0000000000001180-0x00000000000011af SystemIO conflicts with Region \GPIO 1 (20130517/utaddress-251) [ 15.085564] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 15.387333] ACPI Warning: 0x0000000000001840-0x000000000000185f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130517/utaddress-251) [ 15.387383] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver I believe this to be a kernel bug, not necessarily an acpi bug (as I saw this type of bug posted under acpi and it was closed as being posted to the wrong component). I'm not running Gnome or KDE but lxde. Version-Release number of selected component (if applicable): 3.11.0-0.rc5.git6.1.fc20.x86_64 How reproducible: always for a while now. Steps to Reproduce: 1. boot 2. can't adjust backlight. 3. Actual results: can't adjust monitor brightness Expected results: can adjust monitor brightness.

Interestingly enough I booted into Windows on this machine, adjusted the brightness there, and upon rebooting back to Linux the brightness has remained. The Fn keys to increase/decrease the brightness still do not work, however, in Linux at this time.
different hardware but similar symptoms though maybe related: https://bugzilla.redhat.com/show_bug.cgi?id=991737

Hi, I've been working recently on triaging and fixing various backlight bugs, and we're making good progress, hopefully I will be able to help resolve your bug to.

What happens if you boot without these options on the commandline ? Can you try downloading and installing the latest kernel, download the x86_64 kerne l here: http://koji.fedoraproject.org/koji/taskinfo?taskID=7066918 And then install it with "sudo rpm -ivh kernel...rpm" and boot into it without using any kernel cmdline options. If things do not work this way, please walk through: http://hansdegoede.livejournal.com/13889.html Using the 3.15 kernel, and report back the results of all the steps listed there here. Thanks, Hans
Am now using 3.17.0-0.rc7.git0.1.fc22.x86_64 and the following boot line: BOOT_IMAGE=/vmlinuz-3.17.0-0.rc7.git0.1.fc22.x86_64 root=UUID=895ff4c3-db90-4071-aeab-a0ec2d6b94cf ro rd.md=0 rd.lvm=0 rd.dm=0 rd.luks=0 rhgb quiet nouveau.modeset=1 LANG=en_US.UTF-8 And can adjust backlight with no issues using nouveau driver.

That is good to hear, closing this bug then.
