Comment 0 for bug 1119809

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
