Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem?

[Bug 994697] Re: Dell 1370 brightness not working
No, it is not due to a regression, every Linux version that has ever been on it has had the same problem and will continue to have the same problem until a patch is submitted. No updates have made a difference. The problem is no doubt due to the Nvidia graphics on the laptop. I believe the Nvidia chipset handles the screen brightness. I believe it has a geforce 105M. When I say brightness, I mean the actual backlight getting brighter and dimmer. ** Changed in: linux (Ubuntu) Status: Incomplete = New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/994697 Title: Dell 1370 brightness not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/994697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 994697] Re: Dell 1370 brightness not working
Richie Ward, thank you for reporting this and helping make Ubuntu better. Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command in the development release from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux replace-with-bug-number Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. 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'. Please let us know your results.

This laptop uses a nvidia graphics card for display and brightness which
