** Description changed: + EDIT3: I'll withdraw this bug report. + Primary problem here was the combination of "xfce-compositor" with an slow graphics card (mga). + Disabling the "compositor" setting in xfce did it for me. Disabling showing window content on resize+move makes things faster on this graphics card, too. + EDIT2: it seems that even the cpu graph in the top bar produces enough load to get Xorg with Matrox G450 (PCI) busy. Without cpu graph responsiveness is still far slower than with 13.10. EDIT: after deleting almost every file+directory which starts with "." in my home directory, this problem has vanished, but overall performance seems slower than with 13.10. Kind regards, Jochen Dear reader, after upgrading from 13.10 to 14.04 (xubuntu, amd64), Xorg uses 100%, overall reaction is slow and mouse pointer is flickering.
