Successfully build kernel 3.4.2, but now, Ubuntu 12.04 GUI is extremel
I just successfully built kernel 3.4.2 and would like to play around with it. However, just right after I reboot Ubuntu 12.04 with the new kernel, GUIs become extremely slow. Even moving a prompt shell or a text editor window is unbearably slow.
Then, I doublechecked AMD Catalyst Control Centre (I'm using a AMD Radeon 8600 series video card). I happened to notice the Display Properties under Display Manager (
) always pick up a resolution: Preferred (4000X4000), and Refresh Rate is always: Preferred (160Hz). And, unfortunately, I'm not able to change it.
AMDCatalyst Control Centre->Display Manager->Display Properties
Since what I built from the kernel are only 2 files:
initrd.img-3.4.2 and vmlinuz-3.4.2
I'm wondering if I need more files to configure the whole system?
Since I notice for my older kernels, there are at least
abi, config and System.map files under /boot
Can anybody give me a hand?
