[Bug 1159771] Re: Toshiba Portege R830-13C no backlight after resume from suspend
I'm affected by the same bug on Toshiba Satellite laptop in Ubuntu 13.10 (kernel 3.11.0-14-generic). Tried adding acpi_backlight=vendor to grub, but backlight keys still not working after suspend.

Little-bit more details. The keys work, GUI changes and the value in /sys/class/backlight/toshiba/brightness changes from 0 to 7 when changing brightness, however there is no real effect on screen brightness. There is also /sys/class/backlight/intel_backlight/brightness file, which is not affected when changing backlight.

Christopher - thanks very much for your post. You should be unsurprised to hear that I updated the BIOS and it made no difference. I say you *should* be unsurprised, on the assumption you read the rest of the bug. Because we know for sure (a) it works with a patch (b) that Canonical used to have and (c) Canonical has since removed. So your request was fundamentally asking me to jump through a hoop in the hope you could close a bug, knowing very well it wouldn't actually fix the (completely known) problem. But I have jumped through your hoop and it didn't work.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug. Please follow the instructions on the wiki page[0].

[Bug 1159771] Re: Toshiba Portege R830-13C no backlight after resume from suspend
Removed the workaround script, suspended with acpi_backlight=vendor enabled - came back from suspend with backlight at dark, neither hotkeys nor applet worked to get it back. Rebooted with video.use_bios_initial_backlight=0 and hotkeys and applet both worked just fine.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

Sadly, it does appear to exist upstream as well - tested with 3.9.0-030900rc4.201303232035 from that directory. Mainline kernel behaviour is the same: fresh from boot, both the hotkeys and the applet change the brightness OK; after suspend and resume, the laptop comes back but the backlight is off and the hotkeys can't turn it up. Unfortunately, this makes the laptop unusable in Ubuntu for my purposes. However, I can boot back into Ubuntu if there are further tests to do to work on this one. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1159771 Title: Toshiba Portege R830-13C no backlight after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1159771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
