Booting into a newly compiled kernel in ubuntu
I'm using ubuntu 10.10. The kernel version was 2.6.36.
I downloaded kernel 2.6.37 from kernel.org,
performed a build for 2.6.37. I created an entry in the grub for displaying this new kernel.
If I'm booting into this kernel in graphical mode I'm getting errors like
unable to find /dev/fb0
unable to find /dev/agpgart etc
However if I'm booting into this newly installed kernel in SINGLE USER MODE it works perfectly.
I booted into 2.6.36 again to check if there exist /dev/fb0,/dev/agpgart. Yes it exist if kernel ver is 2.6.36 and does nt exist if kernel ver is 2.6.37.
1. What will be the reason for this behaviour?
2. Plz explain me if Kernel and desktop applicatiopn(like gnome,KDE) are seperate entities and how do they interact? How can two different installed kernels can use the same desktop appli installed on a system?
Hope my doubt will get clariffied at the earliest
