Works fine for me.

Heiko, Rex, are you fine with closing this bug, it is definitely fixed in lightdm-1.3.3-2 and lightdm-gtk-1.3.1-1?

Comment 2 Heiko Adams 2012-10-03 10:47:57 UTC
lightdm-1.3 is not available for Fedora 17

Comment 3 Christoph Wickert 2012-10-03 11:57:36 UTC
No, and it probably never will as it brings some changes to the config. I could not reproduce your problem with lightdm-1.2.2-15 and lightdm-gtk-1.1.6 either, so I think it's fair to just close this but NEXTRELEASE. Lets hear what Rex things.

Comment 4 Heiko Adams 2012-10-03 12:14:41 UTC
If you know that lightdm uses VT7 instead of VT1 there is no problem. But if you i.e. press CTRL+ALT+F2 and then switch back to VT1 (CTRL+ALT+F1) the screen stays blank.

Comment 5 Rex Dieter 2012-10-03 13:50:21 UTC
We can close it CURRENTRELEASE as far as I'm concerned.

Sounds more like a misunderstanding which VT is used (if user *assumes VT1, then yes, switching to VT1 won't work).

Comment 6 Heiko Adams 2012-10-03 13:59:18 UTC
Hint: Most users will assume this because AFAIK all other display managers use VT1

Comment 7 Rex Dieter 2012-10-03 14:03:28 UTC
You know how the saying goes, 
http://www.urbandictionary.com/define.php?term=assume

regardless, as Christoph hinted, lightdm was fixed in future version (1.3) to properly run on vt1 by default.

That said, you might be able to achieve the same with 1.2 on f17, edit 
/etc/lightdm/lightdm.conf
to include:
minimum-vt=1

Comment 8 Rex Dieter 2012-10-03 14:10:14 UTC
This build implements the conf change, if minimum-vt conf *is* the culprit here,
