Brightness adjustment goes crazy on Dell Inspiron 1370

[casif]

Binary package hint: hal

Hitting brightness up or down the notification jumps 1-2 points higher and directly back to its old position.
Nothing happend to the display brightness.

My Dell Inspiron 1370 is running Ubuntu 9.10 Karmic Koala.
I have updated the Bios to ver. A02.

[Jola (jcalvat)]

My Dell Inspiron 1370 is running Ubuntu 9.10 Lucid Lynx.
Same problem.
(Sorry I didn't want to select Meverick. I haven't tried yet)

[casif (falticska)]

Well, I have also updated my system today on Ubuntu 10.04 Lucid Lynx.
The problem is still alive :-(

[Arutha (devplace)]

Fresh install of Ubuntu 10.04, with update of 05-05-2010: problem still exists.

[ronald (post-rjdevries)]

Fresh install of Ubuntu 10.04, with update of 12-05-2010. Problem still exists.
If I can help solving this? Please contact me.

[casif (falticska)]

I think it is a problem with the BIOS.
We have to contact Dell to get a new BIOS update.
The BIOS Version A02 do not run correctly with the ACPI interface.

[casif (falticska)]

Solution!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :-) :-)

Add this

Option "RegistryDwords" "EnableBrightnessControl=1"

to etc/X11/xorg.conf under "Device"

regards
Casif

[Liganic (liganic)]

I can confirm, that adding EnableBrightnessControl=1 works!
It is now possible to change the brightness. (Not very fine but it is changeable nonetheless)

[Staffy (staffan-holmberg)]

How do you aply the fix now when there isn't any xorg.conf file? Are there any alternative way of doing it?

Cheers!

[casif (falticska)]

then create one!!

Hello!

I have as well an Inspiron 13z (or 1370), and I have the same problem: When I hit the luminosity control buttons, nothing happen!
I tried all the things above, but that doesn't work!
(For information, I have Inspiron 13z with Windows7 and Ubuntu 12.04 in double boot).

Nobody have got others solutions to propose?

Cheers

Hello,

Carsten's workaround (acpi_backlight=vendor in grub.conf) works fine in my laptop only if I use kubuntu-desktop with KDM. With lightdm and kubuntu-desktop not works, and with gdm or lightdm with unity not works too.

I have A03 bios version and I use default video drivers (not nvidia proprietary drivers).

Regards,

Floren.

[Floren (florenllanos)]

Excuseme,

I forgot comment that I have Ubuntu 12.04.2 (with kubuntu desktop).

Greetings,

Floren

casif, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available 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-v3.9-rc7

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. Please let us know your results. Thank you for your understanding.

See my bug for apport information, I still have this problem and requires a manual (not very noob friendly) config file edit to grub to fix it. Whole point of Ubuntu is that it is a user friendly distribution, this pretty much kills some of the usability for 1370 users.

If there's any other commands you would like me to run for you, let me know. Every new version of Ubuntu that has been released for many years has not fixed this.

[casif (falticska)]

??? I have already solve this problem for years !?????????????

Hi all,

I was using XUbuntu 14.04 on my Inspiron 13z (or 1370) which was working well with the Casif (or Carsten) solution.
For some reason, I had to change my linux to Linux Mint 17. But, the brightness problem came back! and the Casif solution didn't work.
Did anyone have any solution to solve it?
Is it better to use Nvidia drivers or the Xorg drivers?

Regards.

[penalvch (penalvch)]

Onesie45, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu (not Mint) by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:
ubuntu-bug linux
