[Bug 1286774] Re: Xorg crashed with SIGSEGV in read_encoded_value_with_base()

 

tctwyan, thank you for reporting this and helping make Ubuntu better. As
per https://www.asus.com/Motherboards/P5GCMX/HelpDesk_Download/ an
update to your computer's buggy and outdated BIOS is available (0518).
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.
