Lubuntu does not use all of my RAM
I am running Lubuntu 12.10 64bit on my hp nx7400 laptop.
I recently upgraded my RAM to 4GB (2x2GB memory modules), however sysinfo only displays 3.3GB of available RAM.
In the bios I can clearly see 4GB of ram installed and I can also run a diagnosis check on the memory in the bios. So it seems to be operating system related.
So, I am wondering what happened to the rest of it.
In this post: http://ubuntuforums.org/showthread.p...0#post12429300
it is suggested that it might have something to do with shared video memory, however it is not posted how to verify that.
Does someone know how to:
- check the amount shared video memory?
- change the amount of shared video memory?
- find out what else might be the cause?
