[apparmor] [Bug 908864] Re: My Lexmark x2650 printer stopped working after upgrading to 11.10: Idle - File "/usr/local/lexmark/lxk08/bin/printdriver" has insecure permissions (0100775/uid=0/gid=2).

It depends what you mean by adding apparmor=0 at the bottom, you need to
add it to the line containing the linux kernel command options,  it will
look something like this

  linux   /boot/vmlinuz-3.2.0-6-generic root=UUID=b6d5798b-bfb5-4889
-9e2d-92395a82bf18 ro   crashkernel=384M-2G:64M,2G-:128M quiet splash
vt.handoff=7

you add apparmor=0 to the end of the line, eg.
  linux   /boot/vmlinuz-3.2.0-6-generic root=UUID=b6d5798b-bfb5-4889-9e2d-92395a82bf18 ro   crashkernel=384M-2G:64M,2G-:128M quiet splash vt.handoff=7 apparmor=0

and then boot.

As for trying Ubuntu on USB, yes this can help track down where the
problem is, so it is worth trying.  In fact it is worth trying a clean
11.10 too, as the problem may be in some difference caused by upgrading.

Title:
  My Lexmark x2650 printer stopped working after upgrading to 11.10:
  Idle - File "/usr/local/lexmark/lxk08/bin/printdriver" has insecure
  permissions (0100775/uid=0/gid=2).

Status in AppArmor Linux application security framework:
  New
Status in “cups” package in Ubuntu:
  New

Bug description:
  I used Ubuntu 9.04 for a long time and the driver available on the
  manufacturer's site:
  http://support.lexmark.com/index?page=content&id=DR860&actp=search&viewlocale=en_US&segment=SUPPORT&productCode=LEXMARK_X2650&locale=EN&userlocale=EN_US&searchid=1324929199490
  worked perfectly! after installing the newest Ubuntu, I can't even
  finish the installation process of the driver, the Setup says "no
  connection", even though there is connection to the printer, because
  it appears in the list of printers when introduced to the USB.

  from what I have learnt on the web, recent changes in Cups and
  AppArmor caused that the connection to a printer with 3rd party driver
  is often blocked. but this is too high a game for me to solve here...

  have tried in another machine too, the same result, which means that
  THIS PRINTER JUST STOPPED WORKING IN LINUX at all. That is sad. I have
  to go back to older Ubuntu's just for the printer!!!!!!!!!

  This is insane.

  See my debugging results.
