This bug report conflates several distinct bugs, some of which are
fixed.
For a period of time in oneiric lightdm was attempting to set extended
displays and was doing so incorrectly, resulting in a corrupted external
display. We believe this particular issue is resolved in the oneiric
release.
Since this is a production workstation, I can not run Alpha nor Beta
releases. But is there any way to backport the Precise lightdm version
to Oneiric, I'd be happy to try it out.
I wrote a report just a few comments above my screenshot. What else can
I do to help?
Another thing I've noticed
original bug report split off into bug 915408 ; screenshot at the top of
this bug still applies, but logs should be updated.

Just noticed on my Xinerama workstation that when logging out from user
session into login session, all non-primary screens are black. And this
scambling seems to be taking place during night when all monitors are
turned off (by screensaver or whatever used in login session).

I get the same behavior as Daniel Nyström, (btw, how did you take a
screenshot of the login screen?), but only _after_ the monitor has gone

normal -- the primary monitor has the login window and the second
monitor is black (but
Hi,
I have the same problem with my eeepc 1000he (graphic card is an Intel
GMA 945) when I boot on with an external screen (1440X900).
Greeter is present on the two screen (external and internal) but in a
poor resolution.

I finally got a screenshot!
On the third screen you can see almost my complete first screen desktop.
And on the fourth screen you can see an ajax-loader.gif with all it's
animation frames. Is this coming from arbitrary graphics memory? It
sounds more and more like a big security issue.
Thoughts?

I am not sure if this is exactly the same bug, but it really sounds so.
My setup: Notebook in docking station, two external monitors (HDMI 1680x1050,

When LightDM starts HDMI monitor reports Wrong Sync error, VGA monitor turns
black, Notebook display shows correctly. This way I
I do agree with Daniel Nyström; today I found my screen filled with old
data from my last session, this is definitely a security or at LEAST
privacy issue.

Using a lenovo U160 with external 1080p as screen, on 11.04 I had to run
arandr instead of xrandr because the latter did not work properly- the
arandr created a sh that I run at startup making it all work well, *also

Now in 11.10 it works well without script, but the greeting is

Bug #868611 leads to the same results(greeter display resolution being to low)
but could have an other reason:
VGA-0 is detected as connected and so makes X11 mirror both outputs
displaying 1024x788px.

The greeter is displaying correctly now on my setup: both screens are
set to 1680x1050 (at least that is the case with kernel 3.1; kernel 3.0
has a bug that powers down the external monitor when the gdm greeter or
lightdm greeter runs).

I was experiencing one of the bugs marked as a dupe of this one (bug

Current behaviour is that the greeter is displayed correctly (so not

Your system confirmed one issue, that the monitors are reconfigured while the
greeter is running:

@Joe, would you mind checking something?

It is curious that you see the same effect with gdm but it corrects
itself. I wonder if the displays are initialized improperly for some
reason, and the first randr

Other people have confirmed working multi-monitor behaviour.

on both monitors
