GNOME is slow after preupgrade

[W.H. Kalpa Pathum]

Hi all,

My laptop is acer aspire 4736Z

I did a preupgrade from F12 to F13 recently. After that I notice a
significant delay of GNOME from the point I login and to the point
where it completes loading the desktop. Now (in F13) it takes about a
minute to the process whereas earlier it showed the desktop in less
than 10 seconds after I login.

Please help me to solve this issue.
