could we coordinate further processing with upstream? I understand
everybody has a lot of work to do, so I would like to know you are ready
to forward the report and upstream is ready to look into it if I test

Can you confirm that you are still seeing this problem with the natty
release?
If you are, can you test one more thing please - we are now providing
builds of upstream's experimental driver and I'd like to confirm it also
affects their code as well before we send this bug upstream. Please

Thanks a lot for your message and explanation, Bryce. I have used a

Thanks; re-testing xorg-edgers is helpful but this is almost certainly a
kernel bug. xorg-edgers doesn't carry kernel updates, so I wouldn't
expect it'd solve this. Instead, download and boot a new daily cd, then
run 'apport-collect 681054' to update the logs.
This is kind of a borderline

Hi, Bryce! Yes, I am still experiencing this bug. (Otherwise I would
have cancelled the report.) I have been updating my maverick with xorg-
edgers and the bug has not gone away. I have also tried natty from a
live CD, last time was at the time of note #84.
I would also like to remind you that

No Cobalt, those are maverick logs again, you need to have natty logs
from running apport on natty. Otherwise upstream won't look at the bug
report since the versions are too old.

Hi Cobalt, are you still reproducing this bug on latest natty? If so,
like I mentioned I think the next step is to forward it upstream. Now
that natty has been updated to the latest kernel and X bits, we can do
this. Can you again run apport-collect 681054 to put the new logs onto
the bug
Hmm, this should probably be forwarded upstream as the next step.
Betting that both the blinking and the phantom output are related.

Could you run the command 'apport-collect 681054' while running the
xorg-edgers bits? That will attach files with the proper versions,
which will allow us to forward this bug report upstream. Since it
affects xorg-edgers too, it's likely to be a bug in the upstream code,
and they may have more
Another useful thing to try would be to see if disabling the phantom
output makes things better.
To do that you would need to access the grub menu and add “video=VGA1:d”
(if your monitor is not connected via a VGA cable) to the end of the
kernel command line.

Title:

No, I have only one monitor, although at some level - at least for
maverick and older versions - the computer seems to think that I have
two. This is probably at least part of the cause of the other bug
(#606987) I mentioned in the original description of this problem.
Again, maverick runs from
It seems that you've got two monitors plugged in - does this problem
occur on both monitors simultaneously, both monitors independently, or
just one monitor?
Does this still happen if you unplug one of the monitors? (I'd start
with the VGA monitor, as I think it's more likely to have problems)
a) With a live CD for natty, the display is fine up to the screen where
I am shown the menu that includes using Ubuntu without installing. Once
I choose this option the display changes and the name ubuntu appears,
underscored by five dots whose color changes from white to red and back

Hmm, ok reason I ask is looking at your Xorg.0.log everything looks
totally bog standard except at the end there are 9 sequences of XRANDR
queries to the monitor. Those queries can typically cause screen
flickers such as what you're seeing. And it is not unprecedented for
some arbitrary client
If you do rule out a client app, or otherwise want to continue exploring
it as an X issue specifically, here's the next step.
We're going to be moving natty to its new X stack within the next week
or two. Currently this stack is available in xorg-edgers, and should
match almost exactly what will
Regarding xorg.conf on my hard disk, which has Ubuntu 10.10 - I renamed
it so as to have no file with exactly that name, but the problem
persists in 10.10, as it does with a live CD for natty.
Regarding Xorg.0.log - no, it does not grow as the screen goes blank.
** Changed in:
I notice there is a typo in your xorg.conf:
Option metamodes CRT-0: 1680x1050
You're missing quotes.
Also, you should include an explanation in your bug report why you're
using an xorg.conf, since for this hardware you typically shouldn't need
to use an xorg.conf except in
Natty (from USB stick) gives no improvement.
