Unity-greeter installed by default on Lubuntu, crashing on start

Removing unity-greeter solve the problem. It should not be installed on Lubuntu, I'll look at this issue.

Thanks for your report.

It doesn't look like the latest daily. Build id of this report is 20111124 and the version of ubiquity in this report is 2.9.4 while 2.9.10 is on latest daily.
Could you please double check that you used the latest daily ?

I used installer dated 18th Jan as built by zsync from http://cdimage.ubuntu.com/lubuntu/daily-live/current/
Also confirmed by njin (from QA-team) on 'real' hardware..

unity-greeter[1589] trap int3 ip:7fec4fbe4b3b sp:7fff55e32490 error:0

also the build useed to report the bug is 17

same errors for me in 18 on real hardware

Status changed to 'Confirmed' because the bug affects multiple users.

I'm using the amd-64 build

Hum, right, tetsing with the real lastest, and ubiquity stop crashing.
However, unity-greeter is still installed, and lightdm is crashing when starting the new installation.

Upgrading lightdm-gtk-greeter to 1.1.1 seems to fixed the crash problem.

@gilir, that must be in proposed?

either way i don't think it will fix the problem. originally it was described as a blank screen. this is what i got. however, if i typed in my password, i'd login. the way i see it, this is the greeter failing but the dm functioning. am i confuzzled?

> @gilir, that must be in proposed?

No, precise-proposed is empty, which is what I would expect -- during development, -proposed is not used, as far as I know. You can't test updates to something that isn't released, you just work on the development codebase and upload. Once Precise is released, precise-proposed will be used to allow testing of proposed updates to it.

I grabbed and un-zipped the 1.1.1 And it *nearly* installed (Story of my life). The output is at http://pastebin.com/HKS1k1hD if someone would tell me what I'm doing wrong.

I can confirm post #10, the screen is blank but you can type in your password and it launches okay.

I uploaded teh new version temporarly to lubuntu-dev PPA : https://launchpad.net/~lubuntu-dev/+archive/staging until it's in Ubuntu repository.
Please be sure to upgrade to this version, and to remove unity-greeter

@Julien, how long before it arrives on ~staging?

Brings a whole new meaning to "security by obscurity" :)

Hello Everyone,

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

After running the above commands on Lubuntu 12.04 (No, I'm not testing the daily iso, this installing was done 2 weeks or more), I logged out to check the wallpaper and it's ALL black now with light gray bar at the top. I can't see anything but these two colors + the mouse cursor. That is all.

I rebooted my machine and same thing happened. Automatic Login is enabled in my case so I had to log out to see that. So, for me, I have no problem but not sure if someone with Automatic Login disabled if he/she can login or not?

Thanks!

I'm not sure if this is relevant but thought to report it here.

Update:
I logged out, saw the totally black screen again, typed my password, pressed Enter and I'm back to my desktop. So, entering the password blindly does work but of course that's a temp solution.

I got a grey blank screen - logged in blind - system reported a crash in package colord but wouldn't report it. Probably not related but thought I'd mention it just in case. Using latest daily (19th) and wubi.

Wubi, so I was told, is quite unstable until about beta1 time. Although someone had successfully installed it before this bug appeared. My advice would be to subscribe to the bug and try again once the bug is fixed and the daily iso has been tested as ok.

I have tried installing lightdm v1.1.1 from staging and deleting unity-greeter. I could not log on. Re-installing unity-greeter via "Alt F2 - terminal" at least got me back to the black screen so I could log on. It appears that replacing unity-greeter with the lightdm-gtk-greeter v1.1.1 does not resolve this issue.

Confirmed. Installing lightdm-gtk-greeter 1.1.1 provides no change. Removing unity-greeter makes it impossible to log in at all. Like Phill said, using virtual terminal to install unity-greeter and restart gets us back to where we started. This fix actually provides a new problem.

This bug has been reported on the Ubuntu ISO testing tracker.

Still not working, can I have my system running just installing lxdm from tty

updates this morning:
http://paste.ubuntu.com/816825/

included:
2012-01-25 10:21:13 configure unity 5.0.0-0ubuntu3 <none>
2012-01-25 10:21:13 configure unity-greeter 0.2.0-0ubuntu5 <none>

caused repeating crash:
Jan 25 10:30:51 lubuntu acpid: client 3274[0:0] has disconnected

so now the issue isn't that the greeter isn't working but lightdm still allows functionality-- it is just plain broken.

removing unity-greeter did not improve the situation.

installing unity-greeter=0.2.0-0ubuntu4 doesn't prove successful because it can't find it though it is apparently in packages:
http://packages.ubuntu.com/precise/unity-greeter

still problems with the latest daily in its native state, with new lightdm-gtk-greeter and without unity-greeter. not fixed.

The presence of unity-greeter in current builds is very odd. I can see it happening in the livefs build log, but germinate output doesn't show it anywhere relevant, and it doesn't have "Task: lubuntu-desktop".

I reverted the attempted seed workaround because Extra-Exclude doesn't have the semantics that the committer expected and the seed workaround in fact tests out as having no effect on the output.

Ah. The problem here is that the Lubuntu seeds use the "no-follow-recommends" feature, but this is not reflected in livecd-rootfs' live-build configuration. They need to match.

I'm going to attempt to fix this.

This bug was fixed in the package livecd-rootfs - 2.55

---------------
livecd-rootfs (2.55) precise; urgency=low

  * Build Lubuntu with --no-install-recommends, to match its seed structure
    (LP: #918401).

  Disable Recommends for Lubuntu installations (LP: #918401).

A forums thread reports that some people got unity on upgrades from alpha-1 as well, which as far as I can tell is not the intention of the Lubuntu developers. I think the only solution to this for upgraders is to make a manual configuration change:

  echo 'APT::Install-Recommends "false";' | sudo tee /etc/apt/apt.conf.d/00InstallRecommends

I've reconfigured the Lubuntu alternate CDs to install this way by default, and I think you should respin Alpha 2 for that change or you'll have problems later. The desktop CDs will take a bit more work.

This bug was fixed in the package ubiquity - 2.9.16

---------------
ubiquity (2.9.16) precise; urgency=low

  * Bump fallback Ubuntu version number in ubi-language to 12.04.
  * Behave a little more usefully when running over ssh with X forwarding
    such that ubiquity is unable to talk to NetworkManager. This
    configuration isn't actually supported, but is occasionally useful for
    debugging so it helps to be able to start ubiquity at the very least.
  * Configure the target system to disable installation of Recommends if
    base-installer/install-recommends is preseeded to false (LP: #918401).
  * Automatic update of included source packages: flash-kernel 2.28ubuntu39,
    partman-auto 93ubuntu19.
