@gidantribal, the status incomplete in this case looks like it came from the upstream bug report.

[Bug 311716] Re: The slider brightness Applet has value inverted after the last update (2.6.27-11)
I would like to try to summarize the various issues as they appear to me reading the comments. Unfortunately we now seem to have a whole collection of similar but yet different problems in one huge bug and maybe we could untangle it by splitting of separate bugs for those. 1. an inverted brightness control (as initially reported in the bug) There has been a patch in 2.6.27-13.29 that, in theory, should address this by ACPI: video: Fix reversed brightness behavior on ThinkPad SL series (lp#330200) So, starting with the mentioned kernel, the values in the acpi brightness control should get sorted from small to large numbers. 2. No brightness control with the acpi brightness controls present. This, as far as I know, affects only ThinkPad/Lenovo laptops and it should be indicated by a dmesg entry from thinkpad_acpi saying standard ACPI backlight interface available, not loading native one For those, the workaround would be to use options thinkpad_acpi brightness_enable=1 in a file in /etc/modprobe.d. Maybe we should make this the default, though that should be tested well, in order not to break yet some other machines. 3. No brightness control without the acpi controls present The one case of that I saw was an acer and indeed there is a bug in Intrepi'ds acer-wmi that reverts the intended behavior (back off if no acpi support is there but stay if there is). 4. Brightness control working through the acpi interface (echoing values to the sysfs controls) but not through the Desktop interface. Maybe because there have been changes to prevent multiple acpi devices from creating the same VID entry n sysfs. So that could be a Desktop issue. I would propose to open new bugs for 2-4 and verify and keep tracking 1 here. For 2, there seems to be a report open (lp#324061) and it would be best to track that issue there. For 3, lp#86 seems the one matching best but for 4 I did not find a report that sounded like it described that issue. Maybe someone is more successful and could point others there or open a new report for it. Finally 1: is this still an issue with the latest -proposed kernel? If yes, could you add the Laptop vendor and model as well as the output of grep -r . /proc/acpi/video here? -- The slider brightness Applet has value inverted after the last update (2.6.27-11) https://bugs.launchpad.net/bugs/311716 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 311716] Re: The slider brightness Applet has value inverted after the last update (2.6.27-11)
The Fn-keys don't work for me on a Lenovo X300 with linux- image-2.6.27-11-generic (intrepid). Changing throuhg guidance-power- manager in kde4 works, though. I realized that pressing the Fn-keys for brightness up and down changes the value of /proc/acpi/video/VID/LCD0/brightness instead of /proc/acpi/video/VID1/LCD0/brightness (VID instead of VID1). Manually changing the latter (echo 80 /proc/acpi/video/VID1/LCD0/brightness) does change the brightness. This is also reported for arch linux (see http://wiki.archlinux.org/index.php/Lenovo_Thinkpad_X300#Backlight) so it might not be ubuntu-specific. I have in /etc/modprobe.d/options options thinkpad_acpi experimental=1 fan_control=1 brightness_enable=1 and tried withouth all these options, and with options video acpi_backlight=vendor always same behaviour. I also tried with a new kernel with # CONFIG_THINKPAD_ACPI_VIDEO is not set (read somewhere, that that could help, but it didn't). I just installed ubuntu intrepid on that notebook, so I can't say, under which constellation exactly it worked, but I remember, that the keys worked when I first installed intrepid from the CD, before updating. But it didn't work with the 2.6.27-7-kernel, which I tried to boot as well. Should I open a new bug for that?

Hi Till, thanks for that comment and the script. Unfortunately, it doesn't seem to have any effect on my system. It I run that under X in a term, the backlight_control changes, but Fn-Keys still won't work. Do you load thinkpad_acpi with specific options to make that happen? Do you have a custom kernel?

@Terrax Well if you are 100% sure that the problem is not in the kernel but in the package then yes I think you should check for bugs against the kde power management package. First, maybe you want to try poking around in /proc (specific files mentionned in previous bug comments) and make sure that the behavior is right.

[Bug 311716] Re: The slider brightness Applet has value inverted after the last update (2.6.27-11)
@Terrax: I don't think your problem is related to this bug. I've seen the behaviour you describe for battery mode, and it corresponds to having the Reduce backlight brightness option checked in the On Battery Power tab in gnome-power-preferences, then dimming the display on AC power using the corresponding FN key combo (or otherwise), then unplugging the AC cable. It would appear that the reduced brightness is computed with respect to the *original* brightness on AC power, not the *current* brightness; that is why the screen turns brighter. You may file a new bug report for this behaviour if you wish, although it is debatable whether this is an actual bug...

[Bug 311716] Re: The slider brightness Applet has value inverted after the last update (2.6.27-11)
I'm on the Jaunty kernel Version: 2.6.28-4.10, and this last upgrade just broke ACPI backlight control on my EliteBook 8530w, which happens not to have any vendor module for backlight control. The /sys/class/backlight dir is now empty. Interestingly enough, I also have another laptop where the video module works, but gives only 3 brightness levels... but the toshiba_acpi module (in the kernels that happen to have it -- see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/261318 -- gives 5 or 7 or so. It seems like we should not blacklist the _BCM and _BCL modules entirely; we should instead prefer vendor drivers over the video module -- exactly the reverse of the way the upstream kernel seems to be going. -- The slider brightness Applet has value inverted after the last update (2.6.27-11) https://bugs.launchpad.net/bugs/311716 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 311716] Re: The slider brightness Applet has value inverted after the last update (2.6.27-11)
Some clarification for all. I think this went a bit confusing: 2.6.27-10: will have acpi and vendor backlight active 2.6.27-11: started to use only one of those (mostly because acer and sony vendor drivers are incorrect) 2.6.27-11.*smb: should behave like 2.6.27-10 by default So when 2.6.27-10 worked for anyone, my test kernels should work the same. If -11 worked it has to be tweaked. @Olivier, when I verified the module option te result was the acpi video module did not get loaded at all. This could explain that adding the module option help but not why it makes a difference to say vendor or video. After all in both cases the modules should not get loaded. Regardless of this, I just noticed your laptop is a T61. In which case it told me my last patch was also rubbish since it should have detected this and have forced it to the right behavior. Let me try to fix this.

I tried 2.6.27-11.23smb2 on my lenovo t61, which had brightness broken on -11.21 and -11.22. Brightness controls did not work at all with 2.6.27-11.23smb2; however, rebooting with option thinkpad_acpi brightness_enable=1 caused the brightness controls to start working once again. options video acpi_backlight=video in /etc/modprobe.d/options just gave me kernel: [ 14.960104] video: Unknown parameter `acpi_backlight' in my dmesg output, so I don't think that's an accurate test.

Re: [Bug 311716] Re: The slider brightness Applet has value inverted after the last update (2.6.27-11)
@Terrax, sounds promising. :) Thanks for testing. I hope this goes similarly well for the others. No I actually did not revert in that sense. I kept the new infrastructure but added a new default. With the new code added to -11 it was either acpi or vendor backlight control. While before actually both were active and thus causing problems for some others (values changed twice). Long term it should be either the one or the other but it seems this easily breaks. Possibly the hotkey functions in the laoptop specific drivers somehow are too tightly relying on both interfaces to be active. But then trying to get this fixed should be done rather in a development kernel. The way it would be with that patch I made would be to have both interfaces active by default (as before) but additionally allow to specify module options to force only one of those two to be active. -- The slider brightness Applet has value inverted after the last update (2.6.27-11) https://bugs.launchpad.net/bugs/311716 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Stefan Your kernel (2.6.27-11.23smb2) doesn't work for me. I am exactly at the same point as when I upgraded to the first proposed (2.6.27-11.22). Which was, for me, the first regression. Before everything was fine in 2.6.27-10 and is fine also in the recently released in -proposed 2.6.27-11.23. What doesn't work: Brightness is not changeable using the hotkeys, /proc/ or even the scroll bar in the power applet directly. When using the hotkeys, the applet with the brightness progress bar hangs for one second and the brightness doesn't change. Also the default brightness is *very* low (likely the lowest).
