I recently upgrade my debian from kernel 3.2 to 3.9. This leads to a strange problem. After booting to kernel 3.9, it directly goes to tty7 instead of kde login. I can identify that kdm is up and running from ps.

Also, running

service kdm restart

no error message is present.

Another noticeable thing is that now I cannot switch to "tty7" which ought to be the "tty" for graphic contents.

Is there a direction that I can further investigate this problem and, maybe find a solution?

Thank you so much!

  • Thanks maq. I confirmed that it is the video card driver problem, though I am using the official one from the nvidia website. It seems that the dkms is not correctly configured so that the driver does not migrate to the new kernel.
