Incorrect login while resume ubuntu or unlock

[UbuntU-ME]

My ubuntu says Incorrect login while resume ubuntu or unlocking it when locked or even while waking it from hibernation and suspend mode. I don't know what may be the problem but i noticed it suddenly and i don't know what may be causing this. Is there a way to solve this? I have to reboot my computer everytime it goes to suspend or whenever i lock it... Please help...

Are you using the Ubuntu on your EEE PC? This was a bug in the Ubuntu OS for EEE PC. I think in the Netbook remix version. But it should have been solved, Update your Ubuntu and you may get your problem solved... I hope this helps...

Hey, thanks for posting this topic, as i was about to post it myself. Well i have Asus EEE PC and i am facing exactly the same problem. I don't have internet connect at home and i want to solve this, can anyone help me with it? Well i don't know why this problem is caused? The first time login goes well without any problem when starting the computer. Can anyone tell me what would be causing this? Thanks

Yep, there a solution for this one Read this :

CAUSE:

SOLUTION:

sudo chown root:shadow /sbin/unix_chkpwd
 sudo chmod 2755 /sbin/unix_chkpwd
