I used to play with changing fonts alot and fc-cache helped solve some
related issues but I'm not sure it will help here. This seems to be a
BIOS or driver issue, better try a different way to hibernate. In
Linux there are three different solutions:

But first of all update the BIOS to the latest version and
dist-upgrade your Debian, I see on StackExchange that you are using
Debian 6, which is out of support since 2014-05-31 according to
