i got a laptop at work with an amd c-60 apu and two 2gb sticks of ram. bios and memtest see them both for a full 4gb but ubuntu only detects ~1.6gb ram and i can't find why on google. bios has no setting for VRAM share. what do i do

@squirrel considering the BIOS and memtest can see it I can only think that linux is giving that memory to some device or other

graphics is the usual suspect, if you do "lspci -v" it'll show you all the devices and how much RAM each of them is taking

@troubleMoney yeah but how do i change that

@squirrel good question, I'll have to look it up

@troubleMoney vga is getting 256M

memtest said slot 2 was mapped to 00000000-00000000

couldn't find anything like that on google either

@squirrel okay, 256M seems reasonable for that, so it's probably not the shared graphics memory bit that's the issue

no idea what's going on there
