I've been able to make some more tracks with lsinput and input_events (many thanks to Stephan Bader). The issue occur on box A, I'm connected to it from another pc via ssh (box B) to run lsinput and input_events tools.
lsinput only shows that the keyboard is disconnected then reconnected but inform what event is used : /dev/input/event4 bustype : BUS_USB vendor : 0x413c product : 0x2003 version : 272 name : "Dell Dell USB Keyboard" phys : "usb-0000:00:0b.0-4/input0" uniq : "" bits ev : EV_SYN EV_KEY EV_MSC EV_LED EV_REP Then : When I disconnect from my box A session then relog, nothing appear if I write something in a terminal for example. Only mouse events work (I can close a window, move the mouse pointer etc..) input_events 4 show that even if nothing appear at screen before unplug/replug, the keyboard events seems well captured but nothing happen. For example, striking "ls -ali" followed by the enter key in a box A terminal session when the issue is on, is well seen by input_events but it is neither applied nor displayed. I join a small log from this try. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/82368 Title: Usb keyboard doesn't work at log on -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
