Description Robert Moskowitz 2018-09-03 18:36:45 UTC

Description of problem:

The Xfce desktop never starts.  Lighted screen only

Version-Release number of selected component (if applicable):

Fedora-Xfce-armhfp-29-20180903.n.0-sda on Cubieboard2

How reproducible:

Been this way since I started testing F29-Xfce

Steps to Reproduce:
1. Copy image to uSD card, specifying for a Cubieboard2
2. Connect Cubie to HDMI monitor, Kybd, Mouse, console TTY
3. Run screen on console to capture console log and login to console
4. Power up Cubie
5. "Started GSSAPI Proxy Daemon" is the last message on console and monitor before attempt to switch to GUI mode

Actual results:

Lighted screen with no response to kybd or mouse
See:

[  148.658848] alloc_contig_range: [74200, 749f8) PFNs busy
[  165.979868] bridge: filtering via arp/ip/ip6tables is no longer available by [  173.413278] alloc_contig_range: [74200, 74af8) PFNs busy
[  430.058044] alloc_contig_range: [74200, 74500) PFNs busy

messages on console.  Console is very slow to respond.

Expected results:

GUI starts up and whatever system initiation process runs on the Desktop.  I do not know what that will be, as I have yet to get a F29 initial desktop.

Additional info:

The same setup with Centos Gnome:

CentOS-Userland-7-armv7hl-generic-GNOME-1804-sda

Brings up the Gnome desktop.  I have not tried any other F29 desktop.

Comment 1 Robert Moskowitz 2018-09-03 23:23:02 UTC

I was getting ready to power off the system, but decided to look at /var/log/messages first.  Here is what I am seeing on the tail:

Comment 2 Kevin Fenzi 2018-09-04 02:11:45 UTC

Sounds like a crash in lightdm then. ;( Moving to there. 

Also, can you do: 

sudo journalctl -u lightdm -b -1 -l 

might pick up some more info on the crash...

Comment 3 leigh scott 2018-09-04 06:19:18 UTC

Post rpm -qa dbus\* , do you have dbus-1.12.10-2.fc29

Comment 4 leigh scott 2018-09-04 06:33:31 UTC

Also post the logs from /var/log/lightdm/

Comment 5 Robert Moskowitz 2018-09-04 14:45:22 UTC

journalctl -u lightdm -b -1 -l

(just some of the loops, as I have hours of these messages)

I tried a dnf update to see, and no dbus updates currently available beyond what I have.

But I am doing the update anyway and will reboot...

I asked because dbus-1.12.10-2.fc29 is known to be bad and was pulled from updates-testing

Comment 8 Robert Moskowitz 2018-09-04 17:48:00 UTC

After a dnf update, which took a long time, I powered down.  Powered back up and the console froze.  While the GUI session FINALLY went to the setup.  I set the root password, created my user account and finished the setup.  The console took off and I could log in as root.  Here is what was in the update:

Oh, system seemed sluggish at first.

Maybe the lightdm update :-)

Comment 10 Robert Moskowitz 2018-09-04 20:24:28 UTC

I was sooo focused on looking for dbus update, I totally missed the ligthdm update!   Good thing I went ahead with the update.


And this version is still not in the image:

https://kojipkgs.fedoraproject.org/compose/branched/Fedora-29-20180904.n.0/compose/Everything/armhfp/os/Packages/l/


[   ] lightdm-1.26.0-2.fc29.armv7hl.rpm            2018-07-26 15:41  197K  
[   ] lightdm-gobject-1.26.0-2.fc29.armv7hl.rpm    2018-07-26 15:41   56K  

So I would venture to say that we are blocked until this version makes it to the image?

Please let me know when it gets rolled into the image and I will do this test again.

Leigh: can we get this bug added to that update so it can go through the FE process?

Comment 12 Fedora Update System 2018-09-04 22:53:56 UTC

lightdm-1.28.0-1.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-03104b180d

Comment 13 Fedora Blocker Bugs Application 2018-09-05 08:13:52 UTC

Proposed as a Blocker for 29-beta by Fedora user pbrobinson using the blocker tracking app because:

 XFCE is a blocking desktop UX for ARM

Comment 14 leigh scott 2018-09-05 12:15:20 UTC

I Have looked at the issue closely and from the lightdm log it's was waiting for X.

The log normally looks like, lightdm launches X then waits for it to start.

Maybe mesa update fixed this, note the xorg coredump before any lightdm errors/warnings.

The alloc_contig_range() issues sound suspiciously like:

The messages stopped after the lightdm update.

I see them during the update:

And then they stopped.

+1 blocker if this prevents the stock ARM Xfce image from booting to a working desktop.

Comment 18 Chris Murphy 2018-09-08 21:19:57 UTC

+1 beta blocker: "XFCE is a blocking desktop UX for ARM"

I won't be available to test an image until Wednesday.

Comment 20 Adam Williamson 2018-09-10 19:08:35 UTC

Discussed at 2018-09-10 blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2018-09-10/f29-blocker-review.2018-09-10-16.01.html . We received additional feedback from pwhalen. He has tested images on multiple ARM devices and not run into this issue, so this seems very hardware-specific, and thus we decided it does not qualify as a blocker. However, we think it is serious enough to be a freeze exception issue. pwhalen has also tested the new lightdm on multiple devices and found it works fine, so we have confidence that it should be safe to pull it through the freeze.

Comment 21 Fedora Update System 2018-09-11 12:43:36 UTC

lightdm-1.28.0-1.fc29 has been pushed to the Fedora 29 stable repository. If problems still persist, please make note of it in this bug report.

build Fedora-Xfce-armhfp-29-20180911.n.0-sda works on a Cubieboard2.  GUI comes up and setup runs before allwoing access to the GUI desktop.

So I am also saying that this image with lightdm-1.28.0-1.fc29 fixes teh problem.

thanks all

Well there was also a new mesa and I believe Xorg in there so there was a couple of moving parts, either way good that it's now fixed.
