[Bug 1491119] Re: backlight functions keys not working

  Thread Previous • Date Previous • • Thread Next 
Piotr, as per http://www.dell.com/support/home/us/en/19/product-
support/product/latitude-e5430/drivers/advanced an update to your
computer's buggy and outdated BIOS is available (A16). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

** Description changed:

- Hi
- 
-  I have ubuntu 14.04 running on Dell E5430. Backlight control is working fine, but cannot be controlled via function keys (Fn+Up/Down). When xev started all other function keys works correctly, when Fn+UP/Down is pressed sometimes event is registered after +/- 10 seconds, sometimes is lost completely.
