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. -- You received this bug notification because you are a member of AppArmor Developers, which is the registrant for AppArmor. https://bugs.launchpad.net/bugs/908864 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.
