    Ubuntu will not start half the time?

    Hello,

    I installed Xubuntu a couple of days ago, and on that day I decided to install the ATI catalyst driver from the AMD website (due to better performance) for my card. I installed it, but I ran into a common error so decided to uninstall it using it's uninstall script, and now I am using Ubuntu's open source drivers because they are fine for my use. It uninstalled fine, and the open source drivers work, but now, about 50% of the time Ubuntu will not start up. What happens is the screen goes black and starts flickering, then goes blue but it never boots up, just stays there flickering. If I try to boot again afterwards then it works. I have tried to reinstall all of the open source graphics drivers, but the same thing happens. It's really strange.

    My GPU: ATI Radeon HD 6450

    If anyone has any ideas or suggestions please let me know.
    Thanks in advance.

    i suppose that a xorg.conf have been previously created, and now disturb the new config. As the kernel directly deal with X, meaning xorg.conf is not required, you'd better to remove it:

    sudo rm /etc/X11/xorg.conf*

    Thanks for the suggestion. Everything is working fine without xorg.conf, however removing the file still hasn't resolved the issue. I have restarted serveral times, and the screen still flickers and the computer fails to boot about 50% of the time as usual.
    Any other ideas?

    when you say fails to start do you mean this (673.08 KB)? if so look here

    Nope, that wasn't what I meant; no text shows up on the screen at all. My screen just starts flickering and fails to boot up. I think this may be because the ATI catalyst driver messed up something to do with the open source one, maybe it corrupted a config or something? I tried reinstalling the open source one(s?) with Synaptic but no luck.
    Anyone?
