I installed XUbuntu on my netbook and it worked like a charm for about a week.Then, today, the Software center application crashed and since then the window manager stopped to work.Thera are following symptoms:Small buttons for maximizing, restoring and minimizing a window are not visible.I cannot switch between the applications using Alt-Tab.I almost always selected the Save session checkbox in the logout screen.I tried to deselect this checkbox and restart. It didn't help - the window manager is still not working.When I login with a guest account, everything works (but I cannot access my data from the other account easily).I think that there is some cached data, which was not cleaned up and causes the window manager to crash at every login.How can I fix this problem (make the aforementioned symptoms disappear) ?
