keyboard doubles all entries

[[email protected]]

I just completed the installation of 4.3.0-kali1-amd64 without difficulty. However, upon rebooting the machine I find that any letter I type into the username or password fields is doubled, and I am not allowed to log in with the password I gave during setup. During setup there was no apparent keyboard problem, nor is there a problem if I boot single user to the command line. The mouse is also very uncooperative - slow and jumpy. I also notice that the keyboard echo is slow - and the second, repeated character comes about a tenth of a second later than the first.

What to do? Is it possible to prevent the system from coming up in GUI mode? I don't see how to change anything if I can't log in. sshd is not active yet.

I've never had this sort of problem, so I'm going in blind. Maybe try logging in to single user mode and updating Kali to see if that will solve your problem.
Do you have any spare external keyboards that you could try?

I tried a different keyboard - no effect, then used cntl-alt-f2 to get a different login screen. No problem logging in there. I thought I would be clever and create a login that was all doubled letters. That login works on the non-gui login, but not the gui. I would like to start the gui after logging in, but can't find the command to do that. Do you know what it is?

Also, the dragon picture obscures the GRUB menu - is there a way to eliminate the picture?

To start the GUI from command line, type "service gdm3 start".

To remove the splash screen from grub, you need to remove or rename the the grub picture file. I think it is stored in /usr/share/images/desktop-base/desktop-grub.png (either rename the file or delete it) then run "update-grub" without the quotes.

After a bit of research It seems that you can disable key repeats by typing "xset r off"
You can type "xset r" to restore default key repeats.

Have a play around with some of these settings and see what you come up with.

Good luck.

I had this problem as well until I installed the nvidia drivers. OP what video chip or card you using?

lspci -vnn | grep VGA -A 12

I tried that - the prompt returned with no error message but the GUI did not display.

That worked - thanks.

There is a Catch-22 here - I would need to be logged in to issue that command, and the keyboard repeats prevent me from logging in at the GUI login screen. I would need to put the command somewhere in the code that puts up the login screen, and I haven't found where that code is. Using cntl-alt-f2 to get a text terminal is not enough - the xset command issued there doesn't affect the login screen. It would have to be edited into some script that executes pre-login.

Apparently the chipset is ASPEED Grpahics family rev(30). It is a fairly new Supermicro box, had no trouble with Centos or Freebsd.

But where would that command go to have it execute before the login screen was displayed?
I can use cntl-alt-f2 to login without the GUI and edit a script, if I knew which script to edit.
According to the man page the effect of the command does not persist across logins.
