[Bug 883305] Re: Brightness key combinations for adjustment don't work on netbook Samsung N210/N230
Thomas, 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 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 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-v3.11-rc5
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
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.
** Description changed:
- As advised in bug #645624 I open a new bug on this issue.
-
- I just performed a complete format and fresh installation of 11.10 and the keys used to adjust the screen birghtness still don't work. The keys I use are :
+ In 11.10 the keys used to adjust the screen birghtness don't work:
Fn + arrow up = increase brightness
Fn + arrow down = decrease brightness
Fn + F5 = toggle backlight
I also noted that Fn + F9, wich should toggle the wifi network adapter,
- does not work also. It look like bug #296489 but I'm not sure.
-
- I have still to experience the flickering effect mentioned in bug 810093
- so I think it's not the same bug.
-
- It's always reproducible.
+ does not work also.
Proposed solution:
The samsung-laptop module is not loaded automatically since the kernel fail to identify the platform it run on.
I think this issue is the one described in bug #36082 on the kernel bugtracker (can't access it atm, I think the bugzilla has yet to be restored).
The fact is that the N2320 netbook identify itself as N150/N210/N220/N230 but the three other N150, N210 and N220 identify themselves as N150/N210/N220 only.
- This is confirmed by running modprobe samsung-laptop, which result in :
+ This is confirmed by running modprobe samsung-laptop, which result in :
FATAL: Error inserting samsung_laptop (/lib/modules/3.0.0-12-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device
Also the samsung-laptop module is not in the lsmod result. (cf. attachement).
The patch I send, look at the previously mentioned kernel ticket, fixed this issue for me but I wasn't able to test the control back then. This patch have been pushed to stable few days ago.
