How to use full RAM in Ubuntu 11.04 32 bit
Hello ,
I recently installed UBUNTU 11.04 32 bit on my laptop , having configuration intel core i5 460M 4 gb RAM 500 gb HDD Nvidia geForce GT 420M Graphics Card but when i opened system monitor , it showes only 2.3 GB RAM there ! and 4 GB swap (Don't know what swap means) . Where does my rest of memory goes ? (Windows 7 is showing 4GB ram ). And from where i can install correct driver for my Graphics Card . When i install "Restricted Driver Download" it put ends to desktop effect (including my favorite Wobbly effect :( (Don't suggest Compiz please). Pls help ! |
Please don't attach totally unrelated polls to your threads, that is somewhat useless.
To your question: Windows is lying, at least in the 32 bit version. It detects 4GB of RAM, but can not use it to its fully extent. Linux is saying the truth, caused by BIOS issues it is not able to use more than 2.3 GB. You have to either install the PAE kernel (I think in Ubuntu it is the server kernel) or use the 64 bit version of Ubuntu. |
Let me tell you , when i play games in windows my ram usage reaches to 3.2 GB in task manager , so windows can't be lying !
And i am having my data spread everywhere in ubuntu 32 bit . So i can't roll over , i just wanted to use my full ram , if possible ! And about poll , i'll take care next time (noob , i am) . And how to install KERNEL PAE ? |

To install the PAE kernel open Synaptic and search for the package linux-image-2.6.38-10-generic-pae. That is the one to install. Alternatively you can install it with Code:
sudo apt-get update && sudo apt-get install linux-image-2.6.38-10-generic-pae |
I assume you mean you have 2.3 left ready to use and not a total of.
By the way, I have no idea why attracts so many newbies to backtrack. A criminal nature? There is really no legitimate reason for most people to use backtrack. It is a tool for advanced user in a very limited situation. It could be a tool for criminals also sadly like a firearm. |
This is all well described here:
http://www.codinghorror.com/blog/200...es-of-ram.html 32 bit OS limits you to 4GB, not 2GB. But then there are the devices such as graphic card, audio, disk, etc ... Anyway, the URL above is a good read |

I've seen i5-XXXM setups with up to 1.7GB of 'shared' video memory. That would explain the 'missing' memory (1.something GB + 2.3GB = 3.something which is what 32bit non-PAE is normally limited to).
If that assumption is right, installing the PAE kernel might get you some memory back, but I'd doubt you would get more than 200-500MB. Quote:
If your video driver installation failed like that, you probably have a laptop with 'switchable graphics', with the intel video chip used as the main video. You would need to change over to the nidia GPU to be able to install the drivers. That can sometimes be done from the BIOS, sometimes you have to use software. What model laptop is it? |

That's rather weird, that package should be there. Try it with linux-generic-pae instead of linux-image-2.6.38-10-generic-pae
