Ubuntu :: Xubuntu Not Letting Login?

look at my text file cite will not let me put text here keeps saying it is a url. but it is not a url I have an old hp computer with 256mb memory. i updated to the linux image that has the number 17 in the generic. i can not hit esc in grub to enter an the old 14 generic. every thing come up ok with the xubuntu log in screen but when i log in the screen get swrily and set me back to the login screen. on the 14 generic i had to change the realotion to 800x600 becuse the corners were fuzzy on 1024x768. what about setting the rezaltion over a ssh. ssh -C -X parkview@xubuntu xfce4-terminal or is it something else? i did a clean install of xubuntu. i was told to do

reinitializing my XFCE configuration. Log in outside of X (press Ctrl+Alt+F1 to get a console login prompt or login via ssh) and then run the following commands:

mv /home/parkview/.config /home/parkview/.config.bkup
mv /home/parkview/.cache /home/parkview/.cache.bkup

that works exectp when i change the screen resalotion to 800x600. my screen doesnot like 1024x768. after i change it I cant log in any more tell i do

rm -vrf /home/parkview/.config
rm -vrf /home/parkview/.cache

but my screen is back at a crapy 1024x768. i do rm becure i already have it back up the first time. cite would not let me post code kept saying it was a url but it is not
