[Bug 990938] Re: Ubuntu 12.04 AMD64: [Lenovo Thinkpad Edge E220s] Hitting the Brightness Keys Causes the System to Hang
Sos Oganessian, as per http://download.lenovo.com/express/ddfm.html an
update is available for your BIOS (1.38). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change
anything?
If not, 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
Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.
For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.
Thank you for your understanding.

There is a fair bit unexpected behavior related with this bug so it's a
- bit hard to tie down, but it most certianly does not seem fixed.
-
- It's also not 100% deterministic, sometimes it goes bad on the first
- press, sometimes the 5th. It's also worse on 64bit installs. On a 32 bit
- install you actuate the buttom more then a few times before it hangs.
-
- Also:
- Note that in the second bug report, the user, who is running xfce as their desktop, does not appear to mention the problem.
- Note #2 That the E420s (which uses the same bios file!) does not seem to exibit the problem.
- Note #3 Ubuntu seems to detect the ACPI buttons as ASUS buttons. I have no idea who the ODM is, but I was fairly certain that Lenovo was in house, so perhaps this is a misdetect?
