Just got a Z930 and cannot change display brightness at all.

Toshiba portege M400 here, 3.5.0-21-generic #32-Ubuntu SMP Brightness keys stop working after suspend/resume, first time. However, in a departure from others' observed behavior, my backlight/toshiba/brightness controls work. When the system is running after a resume, the 'brightness' value is '7', no matter what the screen dimness actually is. But, if you echo '7' brightness, or any other number for that matter, the brightness changes immediately, and that brightness file does reflect the value that the brightness was set to. HTH. Sure seems like toshibas have been the redheaded stepchild of motherboard feature support since they stopped compiling toshiba support into the default kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935778 Title: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.

[Bug 935778] Re: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.
Seth Jowi, well done on your progress with this bug which I have been tracking for a while on duplicate reports. Since you have the most progress on the problem I have merged the various reports into this one and updated the title description to reflect the various models affected. Seth, there are some attempted patches results in the linked kernel Debian bug reports that might be useful to you if you've not already seen them. Also if you could pass your own patches results upstream (particularly the code beind the working kernel in comment #30), some of the others tracking those reports might have ideas on finishing the job. ** Bug watch added: Linux Kernel Bug Tracker #21012 http://bugzilla.kernel.org/show_bug.cgi?id=21012 ** Also affects: linux via http://bugzilla.kernel.org/show_bug.cgi?id=21012 Importance: Unknown Status: Unknown ** Bug watch added: Debian Bug tracker #599768 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=599768 ** Also affects: debian via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=599768 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935778 Title: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.

Martin: Thanks for gathering all the data. I'm hesitating on the solution from comment #30 because writing to HCI_BACKLIGHT seems to sometimes cause the machine to lock up, and because it's only a partial fix (acpi_video backlight still doesn't work). I'm hoping we can do better, when I have a little more time to look into this. Fwiw, most of the solutions posted on the other bug trackers are variations of what I used in comment #30. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935778 Title: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.

Jowi wrote in comment #29: I tried to work around with the acpi_backlight=vendor kernel parameter. To my surprise with this parameter set intel_backlight seems to be used behind the scenes when the Fn-F6/7 keys are pressed. But after resume the backlight stayed off, hence I don't followed this approach any further. Actually it seems that following this approach just a little further yields a passable solution. It seems that with acpi_backlight=vendor the backlight is off after a suspend, but it can be turned back on by writing to /sys/class/backlight/toshiba/brightness, and then everything works normally again. To all those suffering from this bug: there are instructions at http://www.linlap.com/wiki/toshiba+portege+z830-10f that explain how to enable the acpi_backlight=vendor option and set things up with a script that restores the backlight on resume.

[Bug 935778] Re: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.
Martin: The instructions you linked to work without the HCI_BACKLIGHT patch to the kernel? Interesting. Have you tried it without passing acpi_backlight=vendor to see if the acpi backlight works as well? What about writing values other than 7? The way that toshiba_acpi currently handles the backlight ends up with something virtually identical to what the bios is doing when the backlight is changed via the acpi_video backlight interface, at least on the Tecra R840. So it would be interesting to try doing the same thing with the script, but using the acpi_video0 backlight instead. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935778 Title: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.

Martin: With acpi_backlight=vendor and writing to toshiba/brightness after resume the backlight actually turns on, but leaves me with an empty screen. Xorg shows the following log entries: [ 211.813] (WW) intel(0): flip queue failed: Invalid argument [ 211.813] (WW) intel(0): Page flip failed: Invalid argument I can change to a still working console and back to X, but X stays blank. By killing X I get back a working X server. The Fn-F6/7 keys still manipulate the intel_backlight interface and the screen brightness is changed thereby. Seth: Without acpi_backlight=vendor nothing has changed. There isn't any difference between writing to toshiba/brightness manually or by script.
