@james Ok i got the shell (/bin/sh) and was able to start getty (/sbin/getty -8 38400 tty8 &)and to switch to tty8 (I was not able to login, but i guess thats correct). after I enter your second command the init process starts as usal and after a while the system freeze (meaning i could no longer switch to the tty8) , so i was not able do run apport-collec. So for your question answer 1 is correct.
I add the boot screen again but there is nothing really new (it's still realy random where it freeze so just a cold boot (powerkey pressing for 10s) brings it back to live) expect from the debuging infomation but as ware as i can see there are all normal. ** Attachment added: "boot screen with --debug" https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1256949/+attachment/3930341/+files/IMG_20131216_145519.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256949 Title: Dell Latitude E5420 doesn't boot if killswitch is turned to "radio off" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1256949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
