Hi Adam and PPC guys,
I'm going to give you the honest truth. We are now too late to sort the issues out.*
I know that some of these bugs go back a long while, some are recent. I cannot see any help in my complaining to SABDFL over what has occurred after the changes after A3.*
I propose that PPC follows...
(23:14:36) xxxx: That mail's very long and rambling, and doesn't really give me any concise statement of "this is broken; this is how we propose fixing it".
(23:15:13) phillw: Thinking about this some more, the KMS option shouldn't be the default option on the live/desktop ISOs.* The crashes/freezes with radeon can take some time to appear.* It is quite conceivable that they could occur in the middle of re-partitioning, which would be bad.
(23:15:13) phillw: *
(23:15:13) phillw: The more you think about, the more appealing the Debian way of doing things is: Just rely on the user to add video=ofonly if they want KMS.* This is basically what the boot message says to do at the moment anyway, although it doesn't explicitly mention KMS.
(23:15:39) phillw: what do you need from Debian for the fix to be proposed?
(23:16:28) xxxx: You implied earlier that there was a patch to the driver and/or kernel as an option, not just the command-line change.
(23:18:13) phillw: did you read the email? He accepts that he was probably mistaken on a previous fix?
(23:18:50) phillw: Like I said, up until bug 1058641 I was happy for radeonfb just to be*removed.**This is even though I was responsible for having it put back (along with aty128) into 12.04 -https://bugs.launchpad.net/ubuntu/+source/linux/+bug/949288*.* Incidentally, can I ask the kernel people*was there a reason why*CONFIG_FB_ATY was missed off.....something I probably should of done that at the time?!* Sorry!* I don't know anything about*Mach64/Rage cards, particularly their current state in 12.10....will they use fbdev too now?* Can ubuntu-x confirm?
(23:23:32) xxxx: So, uhm. Reading through that bug, two things jump out. video=ofonly isn't the default, and only when setting this option do things go pear-shaped.
(23:24:01) xxxx: The fix for it is, currently, a custom Xorg.conf, or a custom radeonfb command-line. Neither of those can be done automatically for the user in any sane fashion.
(23:24:46) xxxx: If real code fixes for this can't be found in time, I think the people really familiar with the issue need to sit down and write some CLEAR release notes we can include for people about how to work around this.
(23:26:54) phillw: so, we're pretty screwed? sorry to use that word. If we can get release notes out, I'll support them & then we can look at a fix as a matter of urgency... would that be okay from the guy who is liasion between -release and -kernel?
(23:28:18) xxxx: I think release noting is the only sane way forward here, other than fixing the actual bug. We can't be writing out custom X config files for everyone, nor custom framebuffer inits based on the resolution and refresh rate they may want.
(23:29:19) phillw: As we are too late to fix the bug, would you object to release notes?
(23:29:56) phillw: well, bugs...
(23:31:27) xxxx: I don't object to release notes, no. This is what they're for. In this case, though, the instructions for "how to find your video card and write a custom X config" and "how to switch to using framebuffer-only graphics, and configure your kernel command-line appopriately" are a bit long for a release note, so nice, clear, step-by-step instructions on a wiki page would be great, and then a release note that briefly describes the problem and points to said wi
(23:33:23) phillw: Oh, do not worry about that! I'm also a wiki person, to get a set of steps in for new people will be clear 1., 2., etc...
So, can I ask that you good people get the wiki area up for the release notes? We will go battle on in 13.04
*
For kernel & -x, the PPC team will be looking for the fix. Thanks for sticking with this arch
Regards,
Phill.

I'm sorry. *I know you're trying to get this fixed and I'm sympathetic.
But I don't want to end up in a position where I break something else as
a result, and I'm simply not willing to be held responsible for that
since this is not a field I understand well.
I'm not asking that you get the kernel or X teams to apply a proper fix,
necessarily. *All I'm asking is that you get somebody from those teams
to ack the proposed changes to the boot menu; that way I can have some
confidence that they won't cause some other problem that I have no way
to predict.
Get a member of the kernel or X teams to sign off on a proposed boot
menu change, and I'll apply it. *It would help if this could be as brief
as possible - while I appreciate that you've gone to a lot of effort to
provide many bug references, I'm afraid I simply don't have time to read
through lots of bugs on linux and xserver-xorg-*, given that this is not
my field and so it takes a lot of energy to understand long
back-and-forth threads! *The longer the mails, the less likely I am to
manage to absorb anything beyond the third paragraph or so, given how
much I have to do before the 12.10 release. *I think this may go for the
other developers in question - you really need to be as concise as you
can.
I'm afraid I am finding the long e-mails on many different but related
subjects frustrating and impossible to absorb properly.

Any problem with this is certainly in some underlying toolkit and should
almost certainly not be assigned to ubiquity.

This would be a good thing for somebody to test directly, then.
