I had similar problem in that the mouse worked on the gdm login screen but the keyboard did not.  I was able to login using the on-screen keyboard.

I enabled the on-screen keyboard via the universal access preferences, (little man-in-circle button on gdm screen).  Also had to reboot to get the keyboard to display properly.  Once logged in the regular keyboard worked fine.

I found the :0-greeter.log file in /var/log/gdm had errors complaining about not find symbols for "U.S. English" keyboard layout in  us keyboard file. A little grepping later finds "U.S. English" is set in /etc/default/console-setup.

Reboot and keyboard now works at login.  Don't know if this is VMware's or Ubuntu's fault during install, since I used the auto install process in Workstation 7.  Sounds like it could be VMware related as a manual install seems to avoid this.

Hope this helps.

I can confirm this workaround also works for the new 10.04 RTM released recently.

Ok... Changed some virtual machine settings and the on-screen keyboard finally popped up.  Tried to revert the changes to reproduce but failed. 

The settings I had deselected included Processors=2 (meant to select 2 cores), 3D Graphics acceleration, automatic USB connection, ...? I think that was it.  Reverted everything back to default and onscreen keyboard came up.

After applying fixes suggested and rebooting, I'm able to log in.  Thanks SGiff

ok,

this is how I fixed it:

I still had my VMware machine with Ubuntu 9 so I added the virtual disk of my ubuntu 10 to it, booted, mounted the disk of my new ubuntu and made the changes as suggested above in indicated file (as root).

After that all worked fine..

thanks for the hints !!!

I installed 10.04 LTS on VMWare Player 3.0.1 227600. Took all the defaults and the Easy Install route  I specified 4 cpus. Hit the no keyboard at login so enabled on screen keyboard which didn't appear so rebooted VM but on screen keyboard still didn't appear. Shut down VM and changed cpus to 1. Restarted VM and on screen keyboard now appeared and I could login. Shut down VM again, changed cpus back to 4, started VM again. This time I stil had the on-screen keyboard and the System Monitor shows 4 cpus.

Had a similar problem with Ubuntu 10.04 Desktop and UNE, both the final versions.  Standard VM setup resulted in a VM that would not accept keyboard input, and the onscreen keyboard simply did not appear when I enabled it.

The way I got around it was was to simply remove the floppy drive when setting up the VM initially.  After installation finished, the VM booted into command-line.  Logon, issue a "shutdown -r", and the next time it will boot into the GUI and the keyboard works just fine.  FWIW, this happened on the latest VMware Workstation (7.1.0.261024, which I downloaded yesterday evening).  So it seems to be an ongoing quirk.  Again FWIW, this was on a Dell Latitude D830.

Performing the trick fixed both Desktop and UNE setups

Thank you paologai!

None of the fixes did it until I tried commenting out the xorg.lines! Thank you again!
