Hi,

I would like to ask related to video graphics driver specifically the AMD (radeon HD 7000 series) or had someone with the same experience or problem that im currently experiencing and willing to share some info. I understand that the kernel is self contain it will not affect the installed driver on the system but as i observed on my AMD six core desktop my display will turn sluggish or had some delay when i used the current kernel not the kernel i used to installed the graphics driver. When i fresh installed the lucyd 64bit and update to the current kernel which is 2.6.32-37-generic this is the kernel i used to installed all my application and specially the AMD catalyst driver for linux. But as i observed and update the system which currently as of now has kernel version of 2.6.32-38-generic and 2.6.32-39-generic. When i used this current kernel or besides from the 2.6.32-37-generic my display will turn to sluggish or had some delays as i move or drag open windows explored or application.

My questions:
1. Does i miss something like modules/driver needs to update when i update the kernel. (i had experience with my wifi usb dongle, every time a new kernel release i need to compile the driver/modules in order to function in the newly installed kernel.
2. Or i need to reinstall the AMD catalyst driver every time a new kernel update.(that would be cumbersome)

Or any information that may somehow help me with my problem..as of now im using the old kernel.

Thanks in advance for any input that may help.
