I put http://devel.trisquel.info/makeiso/iso/trisquel_6.0-20130203_i686.iso
on a usb stick and booted off it
and indeed only a plop was heard. Pressing the arrow keys gave more plops.
The grub menu was shown for the 30 second delay and booted to the gdm login
screen which was strange. I was expecting auto login. At this point a plop
sounded. I tried logging in but the screen did not change, it didn't say
wrong credentials but it wouldn't log in either. Just showed the loading
cursor, forever.
At this point I went to VT1 (ctrl+alt+f1) and shut down gdm with sudo service
gdm stop and restarted it with sudo service gdm start. Now going back to GDM
(ctrl+alt-f7) orca was there and talked to me...
This could be a hardware issue all right but I doubt it depends on the
processor vendor. I can believe this would have been impossible to a blind
person to navigate, heck it would have been impossible to most seeing people!
