Package: fglrx-kernel-src
Version: 1:9-3-1
Severity: normal
What did change in the 2.6.29 seems to be the following struct:
- current-euid -- current-cred-euid
- current-uid -- current-cred-uid
- current-gid -- current-cred-gid
Way more things changed, especially with respect to the ACPI subsystem
(specifically, the driver made use of a sizeable amount of private
structures)
The following patch kind of works for me; it seems DPMS is still bust
and I get the occasional lock-up, but otherwise I've been happily
compiz'ing and gaming with it for a couple weeks.
As one of the comments mentions, some parts are still quite dirty and
possibly not DFSG compliant (borderline, at least)
The ACPI side almost works, after running it, I noticed I made the
effort to keep track of fglrx-private data (which used to be stuffed
within the acpi layer's own private data), but I forgot to rewire the
actual notifications. Should be trivial now; might explain the DPMS
troubles.
Anyway, right now I'm pretty satisfied with the way my HD 4350 behaves
with this driver... YMMV, HTH.
