Bug Description
when attending to classes, I use to leave my laptop on on the desk. When I come back after one or two hours, it always requires one minute or more to wake up completely just from the screensaver (no sleep or suspend function).
after that, it is however running slower than ever. CPU is near 100%, all apps require some thirty seconds to get started (i'm talking about the gnome terminal, not firefox or OOo). The only solution to this is to restart Ubuntu from zero :(
I tried to understand if there's an application that eats up CPU, but what's more strange is that while it's, say, 98%, doing ps aux there is no application with more than 3-4% CPU, and if I try to sum the value for every process, it is something like 20 or 30, so I don't know where to start from.
I have an updated Ubuntu Breezy. My system is a ACER Aspire WLMi1652 with Intel Centrino (i686). I use kernel 2.6.12-686
Use gnome-system- monitor or top to check the CPU usage and to see which process uses more CPU most of the time. You should be able to see which program is responsible.
Additonally, try to sort them by memory usage and check if memory usage grows over time.
