we have the same issue on some old machines. open the dhcpd file and add "acpi=off" to the option-129 and un-remark it together with option-128 restart dhcpd service and the reboot :-) file : /etc/dhcpd-k12ltsp.conf # if keyboard and mouse send allllloot of clicks when we click once # then we should disable ACPI in the kernel/BIOS option option-128 e4:45:74:68:00:00; option option-129 "acpi=off"; :-) <div>On 29/01/2008, Vi Thai <<a href="mailto:vthai61@gmail.com">vthai61@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi everyone. We are running k12ltsp with Fedora and I have had a few thin clients that boot to the login screen but when I go to type in the user name it will type in each letter three or four at a time. For example, whenever I type in t it will come out tttt. It took a little while but I was able to login after going back and deleting the extra letters. When I did enter my account I noticed that the mouse was not working normally either. When I click on a menu I would have to hold down the mouse button in order for the menu to continue to display. As soon as I unclick the mouse, the menu would disappear. I always thought that whenever I had a keyboard issue like above, it was because of a bad port, but I didn't know for sure. I've put in both USB and ps/2 keyboards and they both do the same thing. Anyone have similar issues? Is this a hardware issue?
