I recently reinstalled Ubuntu gnome 13.10 , and installed xubuntu-desktop on the side. With my last installation(still 13.10) everything worked fine. This time, howevere logging into XFCE flashes a system error dialogue for a split second before the screen goes completely black. After a few seconds of the blackness, the screen turns the same shade of gray as the Gnome login. At this point there is no cursur, and no desktop. The only way to reboot is to alt+f1 and do it from there.
I've tried reinstalling xfce, xubuntu, compiz, to no avail. Any help would be much appreciated.
