lightdm sometimes fails to register wireless keyboard input

[Miguel]

Hi,

I'm using a wireless keyboard (specifically a Logitech K340, which uses the Logitech unifying receptor), and sometimes lightdm randomly fails to register keyboard input, and I have to unplug and plug again the receptor to make it work. I don't have the same problem with bios, grub or when finally logged in Ubuntu.

Many thanks!

Thank you for your bug report, that doesn't seem likely to be lightdm itself, can you add your /var/log/Xorg.0.log(.old) to the bug and your /var/log/lightdm/x-0.log and lightdm.log?

I think I have a similar problem. I have a Logitech MX720 keyboard (with Logitech Unifying Receiver) connected to a laptop (on a dock). When I try to enter my password in QWERTY lightdm I'm on the MX720 and AZERTY on the laptop.

As soon as I connected no problem the two keyboards are AZERTY.

This is a very restrictive problem since I have to keep the laptop open to input my password.

I've just upgraded to Ubuntu 12.04 and this bug did not exist in 11.10

Oups you must read "When I try ton enter my password on lightdm my mx720 was QWERTY and my laptop keybord was AZERTY" (the previous sentence means nothing at all).

Status changed to 'Confirmed' because the bug affects multiple users.
