Kali 2.0 Running Slow, freezes for 2-5 seconds

[Brun0L3z]

I did an upgrade to Kali 2.0 and immediately i did that and restarted, My desktop will ONLY sure wallpaper and cursor, I solved that by reading alot of posts and what worked was PRESSING
ALT + TAB However, the system runs really slow and so I decided to check on
/var/log/messages and found out that the system was generating alot of these:


Nov 16 11:02:57 Brun0L3z gnome-session[2539]: (gnome-shell:2671): mutter-WARNING **: STACK_OP_RAISE_ABOVE: window 0x6d01600016 not in stack

I did some searches but nothing seems to help.

I am running Kali 2.0 Debian Wheezy 32bit on HP Pavilion M6 1TB HDD and 8GB RAM
no other system is sharing the PC Just Kali

Thanks for any help

Mine is the same, not really usable due to the lag. I tried updating Gnome to 3.16 based on some other posts, helped a little but not much. If you use XFCE desktop its much faster but not as easy to use and looks not nearly as good. Hoping someone finds the answer soon.

I don't have those problem with lite version of Kali which use xfce, but with "big" one I also have same problems.
