A lot of people do have this issue on different distros. I noticed that 256MB of my 4GB where missing on 64-bit, while for a 32-bit PAE there where 4GB. I couldn't find a cause or solution in the Internet. On my machine I found out, that I'm using a NVIDIA graphics that has 256MB own RAM, but the proprietary settings thingy does show that it has got 512MB available. Perhaps your framebuffer is 60GB large :D. I've got no idea why this happened. Regards, Ralf -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
