After installing the new Ubuntu version 14.04 LTS, the keyboard and mouse are not working.
I have Ubuntu 10.10 installed and i want to update to the last version (14.04), so i installed the new version in a new hard disk.
During installation the keyboard and mouse worked fine, after reboot the keyboard and mouse didn't work anymore. If i try to unplug any of them and then i reconnect them, sometimes the system halts.
I have a motherboard ECS C51GM-M, and the keyboard and mouse are PS/2.
It's important to mention that in Ubuntu version 10.10, all still works fine.
Finally, i want to clarify that i'm new in Ubuntu, i haven't installed the previous version.
Thanks for the help
