I’ve upgraded my laptop by changing its RAM DIMMS. It used to have two 1GB dimms and now it has 2 2GB dimms. But unfortunately, Ubuntu “sees” only 3 GB of RAM. After searching the web, I’ve found out that a kernel upgrade should do the trick. And it did. A simple…

sudo apt-get install linux-restricted-modules-server linux-headers-server linux-image-server linux-server

…followed by a restart did the job. Now my system has 4GB of RAM:

tudor@thor:~$ free -m
             total       used       free     shared    buffers     cached
Mem:          4022        764       3257          0         28        310
-/+ buffers/cache:        425       3596
Swap:         3851          0       3851

…which will allow me to run a decent 2GB virtual machine with Windows, so I won’t have any problems running Flex Builder, and perhaps I will emulate a MacOS machine, probably Leopard. I’ve never used a Mac so far and I’m very curious about it. And a real Mac is a little too…”precious” for me at this moment.

PS: I still have two 1GB dimms on a shelf…anyone interested?
