I have an Asus Notebook (2007) with 1 gb ram and 900 Mhz Mobile Intel® 915GM/GMS, 910GML Express Graphics. I use Lubuntu 14.10 with about 300 mb memory usage,but the problem is high CPU usage(100 %) especially when I am playing videos. Also video playing is choppy and laggy especially when I am on facebook and I want to see a video. Please help!
Sadly you are having an awful PC, the cpu worse than the only 1 GB of RAM. What you installed?
Two must-have for a slow and outdated computer: preload and zram.
So, open terminal and type sudo apt-get install preload zram-config -y Then reboot and tell me if your computer is in "better shape" ;)
