[Solved] After update xorg-xdm crashing

IrvineHimself · 2018-05-31 06:23:30

Since xorg-server was upgraded from version 1.19.6+13+gd0d1a694f- to 1.20.0-2 I have been having problems with xrandr crashing when I try to mirror screens. As a temporary fix, I was downgrading the xorg-server.

While this was mildly irritating, it was something I could live with until a more permanent solution arrived. This morning however, a number of other xorg packages were upgraded and, because xorg crashes almost immediately after logging in, the problem has become much more serious

Note: I checked it was not due to the partial downgrade by not downgrading the xorg-server and logging in with the vanilla Arch kernel followed by my more usual linux-hardened-selinux and linux-hardened-apparmor kernels.

More generally, I am using openbox without a desktop environment and the full update log which caused the problems is the following

As yet. I haven't had a chance to completely bisect the upgrade, but, as a first approximation, (after initially running the above update and downgrading the xorg-server,) to get my Arch box stable enough to run further tests, I had to run the following chroot from an Xubuntu usb.

It seems xorg-server 1.20 has issues with xrandr as per https://bbs.archlinux.org/viewtopic.php?id=237463. My 6 monitor setup with lightdm + i3 is also behaving oddly since that upgrade, working fine on 5 of the monitors but refusing to render the lightdm-gtk-greeter on monitor 3, or the i3-status bar on monitor 3, or render any windows on monitor 3. However the mouse pointer travels across monitor 3 just fine.

Update: The following downgrade corrected this issue:

sudo pacman -U /var/cache/pacman/pkg/xf86-video-ati-1:18.0.1-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/xorg-server-1.19.6-2-x86_64.pkg.tar.xz

Did you check the backtrace in the xorg log?

IrvineHimself · 2018-05-31 15:03:14

Firstly, I appended all the logs into one large file and uploaded it to my Google drive. The shareable link to the file is journalctl -b -2

For your convenience, I separated the log files by appropriate versions of:

##########################################################################################
###### Xorg.0.log of failed boot (copied before re-booting by using my Xubuntu usb) ######
##########################################################################################

Anyway,

Sorry, I am not sure what you mean by checking the backtrace. I reinstalled all the suspect Xorg packages and rebooted. After a few minutes, the system crashed and I booted into my Xubuntu usb and copied all the Xorg logs over to my Arch desktop folder.

After once again downgrading, I also took a look at journalctl -b -2. (I know from the linux-hardened-selinux part of the header that this is the correct boot.) From this, I get the impression that it wasn't actually a crash of xorg but something to do with:

As this small snippet shows, this is where it starts to fail; I am unable to log back in and, as a result, I have to hit the power off button.

Xorg.8.log is old, Xorg.0.log is from this noon - but it doesn't look like a complete Xorg log and contains a bunch of xdm errors, please paste the actual file (preferably using eg. https://wiki.archlinux.org/index.php/Li … n_clients)
Also even that X log states that "Server terminated successfully (0). Closing log file.", so "xorg crashes almost immediately" is not supported by those logs (in case it had, the logs would usually contain a backtrace of the X server when segfaulting or aborting)

So maybe start by describing what you consider "crash" itr. - "system crashed" (like a halted kernel) doesn't seem to cut it either?

Also please clarify whether this also affects the vanilla kernel and in case continue the investigation on that to not further complicate the matter.

I am running a fairly major AppArmor project at the moment. So, when something like this happens, the very first thing I check is whether I have the same problem with the vanilla Arch kernel, followed by the SELinux kernel. Since it is good to leave no room for doubt, all further test will be on the Arch kernel.

The actual symptoms are:

Log in
Start the Opera web browser
Prepare to start whatever project I am working on, (currently AppArmor):
- Retrieve sudo password
- Possibly start Vlc media player
- Usually either:
  - Start a Terminal
  - Open Thunar
  - Open the Kate editor
By this point, I will have lost the graphical environment and been kicked back to the terminal log-in prompt
- Is it significant that Xdm doesn't automatically launch?

When I tried immediately logging back in from the terminal:

Appears to log in successfully, but:
It doesn't appear to run .xinitrc
Manually running exec openbox-session kicks me back to the log-in prompt

This last, is the reason why I have been powering off; booting into the Xubuntu usb and creating a chroot.

Since I copied it directly after a crash without editing, that is something I do not understand. To avoid any uncertainty. I did a full update; moved all xorg/xdm logs into a backup folder and rebooted into the vanilla Arch kernel. I have pasted the resulting log to ptpb.pw, and, since it seems to be of interest, I also posted the xdm.log. The relevant urls are:

Looking at journalctl -b -1, once again, everything seems to go to the dogs when polkit complains about an Unregistered Authentication Agent. When I am successfully logged in, for example now, a search of journalctl -b for Unregistered is unsuccessful. Being frank, although I believe this to be significant, I am not certain on either how to interpret it, nor how to proceed.

Thanks for your help and interest

xdm-archlinux.service indeed fails to restart, apparently w/o leaving a log (the pasted one is 4-5 minutes older than the failure), please check the service status (should contain more errors)

However, the problem seems the process that keeps your session running (likely openbox-session?), please paste your .xinitrc
Also I'd suggest to make it run just an xterm and start "openbox-session" (do NOT! "exec" it) from that xterm. In case the latter crashes, you'll still be left w/ an xterm ;-)
Also check coredumpctl for recent crashes.

In case the stuff after

When I tried immediately logging back in from the terminal:

didn't include "and somehow started an X11 server", that's moot - .xinitrc is invoked by startx/xinit/xdm and openbox-session requires an X11 server.

I was having the same: X would close after about one minute and drop me in a terminal. I downgraded xorg-xdm and now it behaves well.

Looks like xorg-xdm may need patches to work with latest systemd

Thanks for that, I was intending to bisect the xorg upgrades this afternoon to see if I could narrow the list of suspects. In view of your of your post, I decided to test this package and can confirm this is the source of the 'crash' problem.

There doesn't appear to be anything useful there, but.....

This is where it gets interesting. After logging back in from the terminal I took the opportunity to first run a few systemctl status checks. systemctl --type=service showed that only the xdm-archlinux.service had failed, and, in case it had useful information, I piped systemctl status xdm-archlinux.service to my Desktop folder.

As you suggested, I tried openbox-session without the exec. Unfortunately, it complained about the Display variable. To make sure I got it correct, I tried again while piping the error to my Desktop folder

Openbox-Message: Failed to open the display from the DISPLAY environment variable.

So the next thing I tried was systemctl start xdm-archlinux.service. This worked; I got an xdm login screen and was able to launch a (new?) openbox-session which crashed shortly thereafter.

In case there was useful information to be gleaned, I once again ran systemctl status xdm-archlinux.service

Finally, to make sure I got everything useful from the session, I piped journalctl -xe to my Desktop folder. This is to big to post here, so I have pasted it to ptb

In view of the mounting evidence that this is almost certainly a problem with the xorg-xdm update, I am going to change the title of the post.

Additionally, All the information I have gathered is here, and if people wish to continue I am quite prepared to do so. On the other hand, given @Lone_Wolf's link, if you feel this is a duplicated/wasted effort, I quite understand

Thanks again for your help
Irvine

If you try the xorg-xdm patch first that should be a quick test.

IrvineHimself · 2018-06-01 14:44:33

I just did that, and it seems to be working. I posted a thank you and am going to mark this as solved.

Thanks again
Irvine
