    9.10, 10.04 Random Memory Leak

    I keep having a memory usage problem. This occurred randomly every once in a while in 9.10 and just happened again in 10.04.
    What happens is, when I turn the computer on, right after I log in, I'll notice it takes an abnormally long time for the desktop to appear. When I check memory usage in gnome-system-monitor, the system will be using ~350 MB of memory, about 100-200 more than usual, which is a lot considering I only have 480 MB total. Plus, it will be using some 80 MB of swap. However, there is no program using more memory than usual in the processes tab.
    Because of the amount of swapping being done (despite having some 100 MB of RAM left), all programs run slowly (very slowly) and make the system nearly unusable. Once it even froze with only 3 programs open, forcing me to hold in the power button for 5 seconds to force-kill it.
    Rebooting the computer always solves the memory usage problem.
    I do not believe this is the xorg memory leak frequently discussed because the high memory usage comes right when I start up. I only have the computer on for several hours at a time and the memory usage doesn't noticeably increase during that time period.
    Checking the log files does not immediately show me anything, though I have no idea what to look for.
    Other sources hint it may have something to do with closed-source video drivers, so I've included my card info here.
