[Trisquel-users] Trouble installing with full disk encryption

[jjw3579]

Hello,

I'm new to Trisquel but not entirely new to GNU/Linux. I've been trying to  
install Trisquel on a T60p laptop using the text installer so I can set up  
LUKS for full disk encryption. If I use the guided setup option to use an  
encrypted disk, it fails. If I do a manual setup, if I try to use  
aes-xes-plain64, it also fails. If I instead choose one of the CBC or EBC  
options, everything proceeds as expected.

Is this normal? I'm conjecturing aes-xes-plain64 may not be completely free,  
or perhaps relies on blobs in the kernel that are not present?

(I know down the road I'll probably have issues with the ATI FireXL graphics  
in this machine, but I'm hoping things will work well enough without  
acceleration to be usable. I'd like to eventually more this machine to  
Coreboot.)
