I try to log in on my linux suse 9.3 computer, The name I can click on and it appears in the
desired place just as last time I logged in .Now I go to the password field and try to type my password but now nothing appears even not the stars, it just stays empty and I can't log in, tried it again after a restart, same problem. Yesterday everything worked fine, whats next to do?

henk32,

It's always best to start at the lowest layer to find out what the problem may be. I would check the keyboard to see if it's getting power. Do this by verifying that the plug is properly and fully inserted. It may be good to physically remove the cable and reinsert it while the computer is shut down to make sure.

From there, when the computer is on, I like to check if the keyboard is actualy on. Press the NumLock key to see if the NumLock toggle goes on. If it does, keyboard is working... and if you still cannot type anything, it may be a bad controller in the keyboard. Try replacing keyboards.

The fact that it worked yesterday and now doesn't points to either cables going bad or a hardware failure, typically in the keyboard. Check those things out and let me know. Good luck!

ive heard this alot that people forget the nulock does not come on when linux is booted and people tend to forget and start typing password in if your password is all numbers than make sure the num locks key is on.

the upper(name) part works Ok , it just refuse to accept any signs in the lower part

Have you tried just typing the password and pressing enter? Ignoring the fact that nothing is showing, just type it anyway. It's possible to have both gdm and kdm set up to not display anything, just like when you log in at command prompt.

Since I'm the only user of this computer I set the computer to this single user mode and to my surprise it worked OK, no more log-in or password needed it just pass this procedure.
Thanks anyway
