[Bug 1516213] Re: Lowering the brightness turns the monitor black in ubuntu 14.04

  Thread Previous • Date Previous • • Thread Next 
Roopa, to advise:
1) You don't have to apport-collect more than once, or any further to this report.
2) Please _stop_ marking yourself as "Assigned to", as I mentioned to you in https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1516213/comments/21 .

Despite this, as per http://www.dell.com/support/home/us/en/19/product-
support/product/inspiron-15-3542-laptop/drivers/advanced an update to
your computer's buggy and outdated BIOS is available (A08). If you
update to this following https://help.ubuntu.com/community/BIOSUpdate
does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

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, and the
information above is provided, then please mark this report Status New.
Otherwise, please mark this as Invalid.

Thank you for your understanding.
