[Bug 1069144] Re: [Toshiba Satellite R830] brightness control works until sleep
** Description changed: On my Toshiba Satellite R830, I have 12.10 AMD64. The Fn + F6, Fn + F7 buttons reduce/increase the brightness level of the screen. The issue is that they stop working after waking my computer from sleep. When this happens I cannot even control brightness by going to System Settings/Brightness and Lock. I had Ubuntu 12.04 installed before and I had the same identical problem. Now I installed the upstream kernel 3.7rc5 and the situation is even worse, because on wakeup, the brightness is at 100% whereas on the standard kernel it remembers the brightness value. WORKAROUND: I modified /etc/default/grub changing the line: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash to: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_osi=Linux acpi_backlight=vendor Then updated grub with: sudo update-grub and the problem is solved. WORKAROUND: As root (not with sudo but actually changing user: su root), change the value in sys/class/backlight/intel_backlight/brightness . For instance: echo 2937 /sys/class/backlight/intel_backlight/brightness or better still: echo 300 | sudo tee /sys/class/backlight/intel_backlight/brightness /dev/null These values are not between 0 and 7 (as the ones in the other directory), but between 284 and 4539, or something like that. Source is http://askubuntu.com/a/196863/27968 .

[Bug 1069144] Re: [Toshiba Satellite R830] brightness control works until sleep
To Do, thank you for posting the results of your search. As an FYI, that bug report is way to broad, and risks being considered useless. It would be best to avoid such reports as upstream largely ignores bugzilla, in favor of the appropriate mailing list. As well, this bugzilla report in particular is more of a forum of potentially related Me too! comments, which is not what you want in a bug report. Instead, one would want maintainers discussing code development or posting patches with a chance of being accepted into the stable kernel. In addition, that report isn't even toggled to the correct provider group, so the appropriate maintainer(s) wouldn't even be viewing that report. Much of the same applies for downstream report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/935778 . Doing Every hardware from a vendor reports is frowned upon both up and downstream. It is also advised to avoid marking this report a duplicate of either at the risk of your problem being marginalized and ignored. The maintainers of the problem you have, would be subscribers of the linux-acpi mailing list (I've had a similar problem with different hardware which went to the linux-acpi mailing list first, and was ultimately resolved in a very timely manner). With this in mind, before we upstream this report in the method requested by upstream, could you please test the newest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10-rc4-saucy/ ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069144 Title: [Toshiba Satellite R830] brightness control works until sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I went through the changes file in the 3.10-rc4-saucy folder and there's absolutely no reference to brightness, acpi, video, toshiba, power management. Is it really worth testing if no changes have been done with respect to this issue? I sent an e-mail with the testing results to the maintainers but didn't receive a reply.

[Bug 1069144] Re: [Toshiba Satellite R830] brightness control works until sleep
Tested 3.10rc3. The problem remains. No change in behaviour whatsoever. I noticed that with Ubuntu 12.10 and hence the 3.5.0 kernel, adding acpi_backlight=vendor increased the number of brightness levels. With Ubuntu raring and the 3.8.0 kernel, this grub command no longer changes the number of levels. However, it is doing something, because if I remove this grub command, when I wake my computer from sleep, the brightness level goes up to maximum, whereas with the Grub command it is remembered. A solution to me seems to make the brightness control associated with /sys/class/backlight/intel_backlight/brightness instead of /sys/class/backlight/toshiba/brightness. This would solve the problem but I don't have a clue how to produce such a change without using scripts, shortcuts associated with those scripts and setting the permissions for the file to 777 or something which allows the user to change the value without using sudo. ** Tags added: kernel-bug-exists-upstream-v3.10-rc3 ** Tags removed: needs-upstream-testing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069144 Title: [Toshiba Satellite R830] brightness control works until sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1069144] Re: [Toshiba Satellite R830] brightness control works until sleep
I've gone through the upstream kernel testing procedure as strictly as possible and here are the results of the tests done. Test Results: 1. One line summary of the problem: [Toshiba Satellite R830] brightness control works until sleep 2. Full description of the problem/report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069144 On my Toshiba Satellite R830, I have 13.04 AMD64. The Fn + F6, Fn + F7 buttons reduce/increase the brightness level of the screen. The issue is that they stop working after waking my computer from sleep. When this happens I cannot even control brightness by going to System Settings/Brightness and Lock. I had Ubuntu 12.04 and 12.10 installed before and I had the same identical problem. With the two previous versions of Ubuntu (and hence kernels 3.2.0 and 3.5.0) there was a workaround: WORKAROUND: I modified /etc/default/grub changing the line: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash to: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_osi=Linux acpi_backlight=vendor Then updated grub with: sudo update-grub and the problem was solved. This workaround does not work with 13.04. Furthermore I noticed that with Ubuntu 12.10 and hence the 3.5.0 kernel, adding acpi_backlight=vendor increased the number of brightness levels. With Ubuntu raring and the 3.8.0 kernel, this grub command no longer changes the number of levels. However, it is doing something, because if I remove this grub command, when I wake my computer from sleep, the brightness level goes up to maximum, whereas with the Grub command it is remembered. I noticed that the brightness keys and brightness and lock settings change the /sys/class/backlight/toshiba/brightness value. Now this no longer has any effect on the actual brightness level after wakeup from sleep. However /sys/class/backlight/intel_backlight/brightness is associated with the actual brightness level, before and after wakeup from sleep. If I change this value with echo 300 | sudo tee /sys/class/backlight/intel_backlight/brightness, the level changes. 3. Keywords Toshiba, brightness control, kernel 4.

To do, thank you for providing the requested information. Could you please test the latest upstream kernel available (v3.10-rc1) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.10-rc1 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed.
