Bug #1119809 “[intel graphics] Desktop login freeze with kernel ...” : Bugs : linux package : Ubuntu

Bug Description

Hardware: ThinkPad X220, 42914CG BIOS, 8DET67WW (1.37 ) – Sandy Bridge, HD3000 graphics

System: Ubuntu 12.04 (amd64, UEFI), Unity desktop, all updates, only kernel 3.2.0-38.59 from proposed

lsb_release -rd
Description: Ubuntu 12.04.2 LTS
Release: 12.04

uname -a
Linux trurl 3.2.0-38-generic #59-Ubuntu SMP Tue Feb 5 17:53:03 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

*** Primary problem – Login freeze

Steps to reproduce:
• Start System
• Login (with newly created user)

Symptoms:
• Empty panel
• Starter with dash and workspace switcher icons only
• SIM PIN dialog (X220 has UMTS card)
• Nothing clickable

Workaround:
• restart lightdm from virtual console oder via ssh
• Login now works
• Remarks: workaround possible on BAT power only – with AC restart lightdm hangs but ssh still works

*** Secondary problem (after workaround) - Blackscreen on resume

Steps to reproduce:
• Suspend (via system menu)
• Resume (via Fn-Key)

Symptoms:
• Blackscreen
• no recovery possible via virtual console or ssh

*** Outputs
Unfortunately ubuntu-bug linux stubbornly insist to say about linux-image-3.2.0-38-generic: "this is not an official ubuntu package", so tell me what additional data you need.

*** None of the above symptoms occur with kernel 3.2.0-37.58

The same issue on the same x220 (4290LU7).
I was able to get access to the desktop after the killing dbus-daemon and re-login.
Bug only affects Unity. Mate and Enlightenment allow log.

idem on a HP with intel graphics (sorry don't have exact model)
This is new and kernel related : Previous kernel 3.2.0-37 is working fine.
On 3.2.0-38 unity crash the graphics stacks, but as previously said unity 2D is working fine.

Hello all,

Same here.
Client is Lenovo E120.
Ubuntu 3.2.0-38-Generic

The launcher shows only 3 icons:
- dash
- workspace switcher
- trash

The menu bar is empty as well (no icons).
Nothing responds when using either the keyboard or the mouse/touchpad/trackball, etc.

My only question is - how do I roll back to version 3.2.0-38-Generic?

5zwvKGFr (5zwvkgfr-deactivatedaccount) wrote on 2013-02-12:

#57

A workaround is to use the previous (3.2.0-37) kernel by default:

sudo gedit /etc/default/grub

-GRUB_DEFAULT=0
+GRUB_DEFAULT="2>0"

sudo update-grub

Vladislava Kozina (vladislava-kozina) wrote on 2013-02-12:

#58

I've found another way to roll-back to kernel 3.2.0-37:

Start terminal

Type sudo apt-get remove 3.2.0-38-Generic

Press Enter
(at some point during file removal it might ask again for confirming file delete - press Y)

Type sudo update-grub

It's funny how it seems no one is thouroughly testing the new kernels before release...

For anyone affected, please try the updated packages from http://people.canonical.com/~herton/lp1119809/ ? Hopefully they will fix the bug (I was able to reproduce and identify the issue).

Hi Herton,

yes, your packages fix the problem.

It works for for me too.
I've installed the three debs for my architecture with dpkg -i

Thanks Herton for your job and the new packages.
When could we expect an official update from Ubuntu repositories ?

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-38.60). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
