Well... after I finally managed to fix the weird install with remastersys on my gf's comp I noticed two things:
1. there is no suspend option
2. hibernate is not really a hibernate as much as death... it shuts down, again with those two errors about unable to activate device
however when I turn it back on, after post and grub and initial progress bar, all I get is either unresponsive blank screen or loads of errors scrolling real fast...
what to do?
