Hi tetsuo55,

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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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

apport-collect -p linux 722377

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. Please let us know your results.

Thanks in advance.

* Tested with fully updated ubuntu: key-combo is still ignored
* Tested with daily mainline kernel: Key combo is still ignored, and even more problems due to missing ubuntu patches.
* Tested with Natty daily live CD: key-combo is still ignored

So all upstreams still have the same bug.

i will remove the needs upstream testing tag and run the apport command.

Hello tetsuo55
Can you please attach here, clicking on the below button 'Add attachment or patch', the file
/var/log/kern.log
from the affected system
Thanks
Fabio

As requested, the kern.log

i came to know this since i posted an issue here.
http://ubuntuforums.org/showthread.php?p=10668799#post10668799
regarding system crashes.
I was a bit sure about crashes while playing video on browser or audio with banshee.
system suddenly crashed.

i did
tail -n 50 /var/log/messages [can be seen there in the post as user "bluepicaso"]

I'm using ubuntu 10.10
core 2duo
dell inspiron 1525

Hi folks,

This bug also a problem on the Dell E6500, and possibly the entire E6xxx series (as well as precision, Inspiron, and other more recent Dells). There are many questions about it in ubuntuforums.org if you search around, plus this Bug #722377 essentially is a duplicate of..

switching to external VGA monitor does not work anymore on dell precision M4400 and Ubuntu 10.04
Bug #585258
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/585258

I've recently posted this..

[ubuntu] 10.4 upgrade - Fn F8 (external monitor flip) not working (post #7)
http://ubuntuforums.org/showpost.php?p=11176214&postcount=7

..where I note that it appears that the scancodes that are issued by the Dell E6500 keyboard are now different than the ones that were issued by my Dell D820 (and on which fn+f8 external monitor switch works with 10.04.x).

Is the keyboard driver and its default keymaps bound into the kernel? If so that'd explain Lucio Crusca's (in Bug #585258) observations of the behavior being different with only booting different kernel revs.

For a workaround is it possible to dynamically load a new keymap that'd fix this problem?

Please, please, please, can we fix this -- I have to do the external monitor switch thing all the time and I really want to get my E6500 working properly. thanks!!!

Having the same problem on a Dell M6400 in Ubuntu 11.04. The key combo worked for me on 10.10 (which was upgraded 9.10 -> 10.04 -> 10.10). Then I recently did a fresh install of 11.04 and the Fn+F8 combo does not work. The screen flickers as if it's trying to do something, but it never activates the external monitor. I have to manually enable the external monitor and disable the laptop's LCD in nvidia-settings, which is quite tedious in comparison.

tetsuo55, 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.

This problem has not been solved yet it appears. I can confirm it is not working on a Dell Latitude E5440 with Ubuntu 12.04 LTS, kernel 3.11.0-24-generic. The FN-F8 key is still not working correctly. I get similar key scan codes as JeffH posted:

I pressed FN-F8 twice here, and then FN-Arrow up (brightness)

# acpi_listen -c 1
^[p
^[p
^@video LCD 00000086 00000000

Here I pressed FN-Arrow up (brightness) first and then FN-F8

# showkey
kb mode was UNICODE
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode 28 release
keycode 225 press
keycode 225 release
keycode 125 press
keycode 25 press
keycode 25 release
keycode 125 release

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