Thanks for your reply
I run Mint 14 Nadia Cinnamon 64 bit.
at first everything used to work fine except my system was llttle bit slow.
what have I done is :
1.I updated my kernel to 3.7.1
when I was trying to update kernel, the codes seems to have worked fine but ended up with a notice which says :
Error! Bad return status for module build on kernel: 3.7.1-030701-generic (x86_64)
Consult /var/lib/dkms/virtualbox-guest/4.1.18/build/make.log for more information.
there was no problem at start up except a few warning .
2.I updated my Nvidia 210 M Grapich card driver
I used this code
sudo apt-add-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings
there are some warnings at startup .the system works smoothly and faster.
I dont have a desktop en. anymore probably. it looks like windows or kinda XFCE DE
but mouse icon disappeare when it comes on an icon. and Nvidia X server setting says :
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
3.I updated my kernel to 3.7.6 with this code
... rnel-3.7.6 -O kernel-3.7.6
chmod +x kernel-3.7.6
sudo sh kernel-3.7.6
there are still problems similar to before
4.I tried to restore my kernel to 3.5.0 by using " previous versions" option at booting
now my kernel is 3.5 but there are some problems at start up and the problems with nvidia driver is the same
I dont want to have latest kernel or nvidia driver..I just want them to work together smoothly ..I dont know if I installed open code nvidia driver or not btw.
Now system tools > system setting> graphics says my driver is VESA: GT218 Board - 0689a740
