[Bug 1327466] Re: on login, X goes to blank screen, regression in 14.04


Jay Vosburgh, thank you for reporting this and helping make Ubuntu
better. As per http://support.lenovo.com/us/en/products/desktops-and-
all-in-ones/thinkcentre-m-series-desktops/thinkcentre-m70e an update to
your computer's buggy and outdated BIOS is available (90KT18A). 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

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 New.

Thank you for your understanding.

  on login, X goes to blank screen, regression in 14.04

Status in xorg package in Ubuntu:

Bug description:
  Note: this occurs when booting the 14.04 desktop installer ISO as
  well, not just on the installed system.  Booting any of 13.10, 12.04
  or Fedora 20 does not exhibit the same problem on the same machines.

  For the installed system, after logging in, the desktop comes up and
  works for a few seconds (~10) and then the screen goes blank (and
  switches to power save).  Switching (Ctl-Alt-1) to a text console and
  back will sometimes bring the graphics display back, and sometimes
  won't.  When the display is restored, it exhibits one or more of the

  - popup  "could not switch the monitor configuration, could not set
  the configuration for CRTC 63"

  - executing "xrandr" (no arguments) causes the display resolution to
  flip between 1280x1024 and 1440x900

  - works for a short while, then goes black again

  Examination of the Xorg.0.log shows that during the initial blank
  screen time, X is rapidly cycling back and forth between those two

  [    37.124] (II) intel(0): resizing framebuffer to 1280x1024
  [    37.128] (II) intel(0): switch to mode 1280x1024@76.0 on VGA1 using pipe 0, position (0, 0), rotation normal, reflection none

  [    37.785] (II) intel(0): switch to mode 1280x1024@76.0 on VGA1 using pipe 0, position (0, 0), rotation normal, reflection none

  This has occurred with two machines (with similar hardware, Intel Core
  2 Duo with embedded graphics) connected to a particular monitor (a
  Lenovo L194, 4434-HB6).
