I have a freshly installed Ubuntu 14.04 on a Dell E5450. The hard disk is fully encrypted on installation.
The laptop's keyboard is working fine, yet I have trouble when trying an external USB keyboard and mouse. They just won't work past the grub menu.
(I even have the feeling that USB isn't working at all post-grub.)
It's not a hardware issue, as the Live Stick will boot with keyboard and mouse support just fine.
Yet once I have to enter the passphrase to unlock the encrypted hard disk, I cannot type and even in Ubuntu itself it won't be recognized.
I've looked into this issue and found a bug report, yet none of the provided workaround seems working for me.
I tried adding these to my modules list:
$ cat /etc/initramfs-tools/modules # List of modules that you want to include in your initramfs. # They will be loaded at boot time in the order below. # # Syntax: module_name [args ...] # # You must run update-initramfs(8) to effect this change. # # Examples: # # raid1 # sd_mod hid usbhid hid_generic ohci_pci
sudo update-initramfs -u
Yet no luck.
How can I fix my USB for Ubuntu14.04 using full disk encryption?
