fedup 20 -> 22 -> improper X rendering

I used to update: Coming up in graphical target as default.target, KDE X does not render properly. With right click I a small box appears under the cursor, navigating to what I guess is the first menu item, I can start a console. A box appears. I click into it and type: Another box appears and I can launch another xterm from it. At any of the xterm's (and console) I can enter commands. The area where the xterm prints my input text and any resulting output text is drawn ... but not the rest of the xterm (which remains the background image). I can find the top of the xterm box and move it ... it leaves a trail of sides of the xterm as it is moved. Any xterm over which I move another xterm, does not refresh it self. Basically, X is unusable. # /sbin/lshw -c display *-display description: VGA compatible controller product: G73 [GeForce 7300 GT] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:29 memory:fd000000-fdffffff memory:d0000000-dfffffff memory:fc000000-fcffffff ioport:bc00(size=128) memory:fe8e0000-fe8fffff No nvidia drivers are installed: <nothing> akmods 0.5.4-1.fc22 noarch kmodtool 1-23.fc22 noarch libmikmod 3.3.7-1.fc22 x86_64 kmod-libs 21-1.fc22 x86_64 kmod 21-1.fc22 x86_64 The contents of /etc/X11 is the same post upgrade to fedora 22 as it was for fedora 20 (I kept a copy of 20's /etc/X11 directory).

Alas, success elsewhere did not guarantee success with my main machine. Any help would be appreciated. Thanks Richard
