I have a notebook computer running Suse Linux and Ximian Desktop. The computer does not run very fast and the mouse is "jerky". I opened the System Monitor and it is using 246 of 250 MB of RAM and the CPU is running at about 28-32%. This has me a bit concerned. I always thought that Linux used considerably less RAM than Windows, but this is more than XP uses! Can someone tell me what is going on? I'm trying to learn how to use and troubleshoot Linux. I'm obviously new to Linux, but not a helpless Linux neophyte. Any help is appreciated.
