[Bug 1293840] Re: black/blank screen immediatly after login

 

Emily Gonyer, as per support.lenovo.com/us/en/products/laptops-and-
netbooks/ideapad-z-series-laptops/ideapad-z470 an update to your
computer's buggy and outdated BIOS is available (38). 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, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  black/blank screen immediatly after login

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  After logging in, within ~5 seconds, I get a very brief (1-2 seconds)
  of a blank, black screen, which then immediatly goes away and my
  system runs normally. I don't get any notices of crashes or errors
  either before or after - just a very brief, blank, black screen.

  I'm currently running an up-to-date 14.04 Ubuntu install. I did
  (briefly) attempt to try out Mir/Unity 8 a couple weeks ago, and spent
  a few hours getting my system back to normal afterwards, but have
  otherwise just kept up with updates.
