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. Thanks in advance. ** Description changed: Pressing Fn + Brightness Up and Down results in the brightness indicator jumping randomly up and down, with no change to the actual brightness. This laptop uses a nvidia graphics card for display and brightness which is not supported by ubuntu's default configuration. There is only one way that I have found to actually make the brightness go up and down: 1. Add acpi_osi=Linux acpi_backlight=vendor ro to /boot/grub/grub.cfg 2. Type echo 5 > /sys/class/backlight/nv_backlight/brightness And even with acpi_backlight=vendor switched on, using the Fn key to affect brightness still does not work, presumably because its trying to use dell_backlight, which does nothing. Output of ls /sys/class/backlight with acpi_backlight=vendor: root@r-Inspiron-1370:~# ls /sys/class/backlight dell_backlight nv_backlight - root@r-Inspiron-1370:~# + root@r-Inspiron-1370:~# Normally this only contains acpi_video0 (off top of head so might be a typo). I think someone needs to make a patch to fix this bug. - --- + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
