mdv2010 'buggy' after update

[hawklord]

hi,

 

i've just fully updated my mandriva via urpmi --auto-update and ran into a few problems,

 

first - got a white screen only, solved this by using the vesa driver, then going to mcc and swapping back to my nvidia driver - which updated itself,

 

now i have a really 'jerky' screen when i move items, there is a lag when i open the application launcher and its slow to move to another section,

 

i have compiz enabled but enable desktop effects is not checked,

 

my graphics card is an nvidea gforce 8500gt

 

 

is this a graphics card problem or something else ?

 

ta for any help
