After using Mint 7 main problem free for about a month my system has started slowing down with mouse lagging and media skipping after running for 5 hours or so and gets continually worse. Htop tells me the worst offender is Xorg which runs at under 1% for the first hour or so then gradually accumulates share of the CPU.
At first I had thought this was due to switching to Openbox but the problem is the same in Gnome now, another difference is that I swapped out network manager for wicd which probably has nothing to do with it.
Had been running Jaunty fine for months beforehand so I doubt it's hardware specific.
