> Title:
>  [MASTER] fglrx failed to install/upgrade due to being incompatible
>  with 2.6.38 kernel
>
> Status in “fglrx-installer” package in Ubuntu:
>  Fix Released
>
> Bug description:
>  [Problem]
>  The -fglrx driver needs updated to work against the 2.6.38 kernel, as the
> current version is incompatible.  It also needs updated to work with xserver
> 1.10, which was added to Ubuntu on 1-31.
>
>  [Workaround]
>  For now, the only work around is to uninstall -fglrx and use the open
> source -ati driver, which supports 2D on all AMD cards, and 3D on nearly all
> of them.  AMD will be providing an update to their driver eventually, which
> hopefully should make it in time for the natty release.
>
>  [Original Report]
>  This problem I have with kernel 37-12 and 38-1.
>  But with 37-12 startup is possible with a buggy system.
>  With kernel 38-1 gnome will not startup.
