Cannot enter LUKS passphrase after installing nvidia-current

[Alan Pope 🍺🐧🐱 🦄]

Installed 15.10 AMD64 on a MacBook Pro 7,1 and used LUKS full disk encryption
Did all updates
Added nvidia-current to get the binary blob GPU driver

Reboot, get a "please unlock disk sda3_crypt" screen which has an input box, but if you type in it, the text appears on the screen elsewhere.

@Mathieu, unsure if that could help but Debian had this patch (which is in upstream 0.9.2) that fixed password enter issues

[Mathieu Trudel-Lapierre (cyphermox)]

We've tested this patch, it doesn't appear to solve the issue. That was indeed my first guess :)

[Philippe Coval (rzr)]

I confirm this on LTS trusty with dell optiplex 9020 (nvidia gfx) so I am reverting to 3.13 or 3.19 ?

[Philippe Coval (rzr)]

Yea actually 3.19 and 3.16 are broken , 3.13 is fine, I can test other kernels if needed.

USB Keyboard is working again once upgraded to :
Linux version 4.4.0-999-generic (kernel@gomeisa) (gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2) ) #201512202100 SMP Mon Dec 21 02:02:12 UTC 2015

Note PS2 keyboard worked on earlier versions , but not nouveau nvidia driver (not in regular resolutions).

Unfortunately It's not very stable, but that's other bugs to open...
