I think this might be related to bug 1790525 or bug 1812359. So keep an
eye on those.

[Daniel van Vugt]

Those repeated messages are probably just a consequence of still having
debugging turned on. Maybe now is a good time to try with debugging
turned off in /etc/gdm3/custom.conf so as to generate smaller logs.

No I haven't ever heard of that. Usually on a Macbook you just hold the
Option key at startup to select a boot device. Maybe you are seeing a
quirk of the old model or maybe you are experiencing a hardware fault.

In fact, if you can't get any Linux to work reliably then hardware
faults start to become a more realistic explanation. But I don't see any
solid evidence of a hardware fault yet.

Hey Daniel,

The other thing I noticed in the the boot logs are a seemingly futile
loop:

This appears first at 11:38:36 in the first boot log, and then repeats
over and over and over until the machine turns off.  The same loop
appears in longhangprevboot2.txt and starts at 12:21:55.  What is the
machine trying to do here?  I suspect that this is what's happening in
the background when the computer hangs, and it may even describe why
it does not record the whole boot sequence for the 20 minutes after it
hangs.  Thoughts?


I have not used Ubuntu 16.04, nor Lubuntu 18.04.1.  I'll download
Lubuntu and see how that works out.  But, I am a little concerned
about getting it to install correctly.  Whenever I try to get the
computer to recognize the CD image and to boot from it, I have to spam
"1" and "Enter" over and over and sometimes it works.  Have you run
into this issue before?

[Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed [Apple Macbook 2, 1 - Intel GMA 950]

[Daniel van Vugt]

You're right - those logs are apparently from short boots.

longhangprevboot.txt lasted less than 2 minutes and only 2 seconds
between GLSL errors and the machine beginning to shutdown.

longhangprevboot2.txt lasted 2 minutes and again was only 4 seconds
between GLSL errors and the machine beginning shutting down.

Maybe that's a hint at a bigger problem if the system clock is running
slower than reality..?

Do older releases like Ubuntu 16.04 work on it? How about Lubuntu
18.04.1?

Re: [Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed [Apple Macbook 2, 1 - Intel GMA 950]

[Alexander A Theiler]

Hey Daniel,

I've recorded two long hangs for you and your team to analyze.

Please find attached longhangprevboot.txt and longhangprevboot2.txt.

The only difference between the two is that longhangprevboot.txt followed
the following timeline:
normal mode -> restart to long hang -> restart to recovery mode and record
previous boot

Whereas, longhangprevboot2.txt followed the following:
normal mode -> restart to long hang -> restart to normal mode and record
previous boot

I let both of these boots hang for about 20 minutes before restarting the
machine.  Strangely, both logs don't seem to reflect that.  Unless they do,
and I simply didn't interpret the data correctly.  Ideas?

Thanks

Alex

Yes please for a new log.

This bug is almost certainly fixable. We just need a complete log, and
then a lot of patience to wait for some upstream developer to get around
to figuring it out.

If you can't wait and want to use the machine now then Lubuntu might be a 
better option:

[Alexander A Theiler]

Hey Daniel,

Yeah, at the beginning of this all, I thought it was taking a long time to
boot as well, but even after letting the system sit at the purple screen
for quite some time, it never went anywhere.  I had a though that my
ancient laptop might simply be too old to properly run Ubuntu, but I was
optimistic.  What's strange is that after it crashes, it boots entirely
normally, and runs very well without any lag or video issues at all.

I'll chalk this up to being a bug related to my system being quite old.

Do you still want that new boot log after 15 minutes of waiting?

Thanks

Alex

[Daniel van Vugt]

Alex,

It's unclear how long this bug will take to get resolved, if at all.
Even if you find the machine does start up after 15 minutes or so, it
might not perform well enough to be usable.

If you would like to use Ubuntu on it then maybe the lighter weight
Lubuntu is a better solution right now:

Note to developers: This system seems to have an Intel GMA 950 GPU.
Limited to OpenGL 1.4? So it is much older than the CPUs that bug
1727356 was about. Still, this system should start up eventually even if
using software rendering.

But that GLSL trouble might not be the real problem. If you look at the
timestamps you can see there is only 4 seconds between the GLSL errors
and the machine being told to shut down. So I suspect you're not waiting
long enough for the machine to start up and killing it in the middle of
the start-up process (which seems very slow, but still seems to be
working). Please try waiting 15 minutes next time and send us a fresh
log from that.

Re: [Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed

[Alexander A Theiler]

Hey Daniel,

You were right - the computer was stuck in recovery mode.  I manually
booted it into normal mode and then restarted it and re-produced a hang.  I
then rebooted into recovery mode and recorded that boot with journalctl
-b-1 > prevboot.txt.  Please see attached.

The log states that the boot began on 1/11/19 and continues until 1/21/19.
However, if you look at the log itself, the only data recorded is from
today, 1/21/19.  I don't know where it's getting 1/11/19 from.  So, despite
the log at the top stating that the boot record spans several days, the
record itself only reflects one day.  And the file is appropriately small.
I sincerely hope this is what you're looking for, despite incorrect dates.
Can you take a look?

Thanks a ton,

Alex

[Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed

[Daniel van Vugt]

Although you have provided some logs that are not in recovery mode,
those logs span multiple days so are not helpful in pinpointing the
immediate problem.

When sending logs in future please ensure they don't mention "recovery
nomodeset", AND that the earliest and oldest dates in the log file are
the same day within a few minutes of each other. That should be
guaranteed by following the steps in comment #2 closely.

[Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed

[Daniel van Vugt]

I suspect the mistake is that you are not manually un-selecting recovery
mode, so it is always rebooting in the same mode as last time, so is
always in recovery mode.

Either that or the non-recovery mode boots are failing to record a log
at all. But I suspect it's more likely you're stuck in recovery mode
even after rebooting.

Try selecting a kernel at startup that is not recovery mode. Then
reproduce the hang, and then reboot into recovery mode...

Re: [Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed

[Alexander A Theiler]

Hey Daniel,

I'm honestly not sure what I'm doing wrong.  Here's precisely what I'm
doing.  Tell me where I'm messing up:

First, I booted into recovery mode by hitting Esc on bootup, and selecting
boot into recovery mode.  The computer then boots, and reaches a point at
which it I have multiple options, the first one being continue into a
regular boot, and a then there are a few others, like "drop into root."

In the previous email, with the previous file, after booting into recovery
mode, I then selected "continue regular boot" and then I edited the
/etc/gdm3/custom.conf to enable debugging.  I then rebooted and reproduced
the hang.  I then rebooted into recovery mode, and then continued booting
into normal mode.  I then sent the files, were were apparently wrong.

Here are two more files.  Since /etc/gdm3/custom.conf already had debugging
enabled, I did not reboot the computer into recovery mode.  I simply
rebooted the machine, let it boot as normal and hang while loading as it
usually does.  I then rebooted the machine, tapped Esc, and selected "boot
into recovery mode." It paused after booting for a few seconds, and gave me
a few options.  This time, I chose "drop into root" and ran the command
"journalctl -b-1 > prev_boot.txt" but I'm not sure where it saved.  I then
selected for the computer to boot as normal, out of recovery mode.  When I
entered Ubuntu, I ran two commands, "journalctl -b-1 > prev_boot.txt" and
attached it here.  I also ran "journalctl -b >prev_boot2.txt." Between the
two boot records, I hope one is correct.  Prev_boot.txt is extremely large
again for some reason, and in the logs, it says the boot sequence started
on 1/11/19, which is absurd.  What's going on with that?  Strangely,
prev_boot2.txt is much smaller but also states that the boot sequence took
over a week.

Sorry for the lengthy email.  Where am I messing up on recording the
boot?

Sincerely,

Alex

That boot seems to be starting from 11 Jan. Does it also include debug

Regardless, it's a little too old and unnecessarily large. Please follow

Alex,

The log in comment #3 is from recovery mode, not what we need.

Please follow the steps in comment #2 again, but before sending
'prev_boot.txt' try compressing it to make it smaller:

  xz prev_boot.txt

and then send us 'prev_boot.txt.xz'

I received an error from Launchpad stating that the previous file I sent
was too large (14 MB) and could not be delivered, and so I repeated the
above steps again.  Here's another failed boot log, and for some reason,
it's much, much smaller (836 KB).

[Bug 1811599] Re: When booting, the computer hangs at a purple screen and no login prompt is ever displayed

[Daniel van Vugt]

Please:

1. Boot into recovery mode and enable (uncomment) debugging in 
/etc/gdm3/custom.conf
2. Reboot into normal mode and reproduce the hang.
3. Reboot again into recovery mode and run:

   journalctl -b-1 > prev_boot.txt

   and then send us the file 'prev_boot.txt'.

** Changed in: gdm3 (Ubuntu)
   Status: New => Incomplete
