[Bug 2127724] [NEW] Less RAM

Public bug reported:

Hello! (sorry for my bad English im French)
Since I installed Ubuntu 25.04 with the software updater in Ubuntu 24.04.3 LTS, I have only 3.3GB of DDR3 RAM usable but I have 4GB of RAM in my old laptop, if you want the model name of my laptop, its: NP300E5A-S04FR, by SAMSUNG in OCT 2011. Before upgrading to 25.04, I had 3.8GB of RAM available. So my PC is way slower than before (I guess its because I have a 14years old HDD). I have two different GPU, I disabled my Nvidia Geforce GT 520 MX because on youtube videos it was terrible, I blacklisted the open source nvidia driver 'nouveau' and its still 3.3GB. So if you have any ideas of what this happens or a fix, please, tell it to me. And if you have an official driver for my Nvidia GPU that works without breaking GNOME, please give it to me.

Thanks earlier for replying. Bye.
