[nvidia] Xorg crashes after system sleep / wakeup, in libwfb.so+25597 → nvidia_drv.so+60a46c → [heap]+d35cb0

[Ákos Maróy]

after putting the system to sleep, and waking it up, Xorg crashes, and I'm lead to a new greeter / login screen. naturally the state of my desktop is lost in this process, and I'm stuck with a new login with no apps running.

the error reporter says:

Error: [Errno 21] is a directory: '/proc/driver/nvidia/gpus/0000:01:00.0/'

which is indeed true:

$ ls /proc/driver/nvidia/gpus/0000\:01\:00.0/
information registry

the same system worked fine with ubuntu 17.10

In order to debug a crash we will need a crash report. To create one, please:

1. Apply the workaround from bug 994921.

2. Reproduce the crash.

3. Look in /var/crash for crash files and when found, run:
   ubuntu-bug /var/crash/YOURFILE.crash

4. Add a comment here telling us the ID of the new bug that was created in step 3.

[Ákos Maróy (akos-maroy)]

can you be more specific about the workaround. I read but 994921, but didn't find a clear reference as to what would need to be done

[Daniel van Vugt (vanvugt)]

It's at the top of bug 994921.

Additionally, or alternatively please uncomment this option from /etc/gdm3/custom.conf:

# Additionally lets the X server dump core if it crashes
#Enable=true

and reboot.

[Ákos Maróy (akos-maroy)]

done. the new bug is bug #1770322

this was created by running ubuntu-bug xserver-xorg-core

I wasn't able to determine the big ID when running ubuntu-bug /var/crash/_usr_lib_xorg_Xorg.0.crash . also the system seemed to automatically run ubuntu-bug /var/crash/_usr_lib_xorg_Xorg.0.crash after logging in

[Daniel van Vugt (vanvugt)]

To see previously reported crashes, try this:

https://errors.ubuntu.com/user/ID
where ID is the contents of /var/lib/whoopsie/whoopsie-id

[Ákos Maróy (akos-maroy)]

should be this one: https://errors.ubuntu.com/oops/68c71690-5413-11e8-80d4-fa163ef911dc

Thanks for the link.

It appears your crash occurred in the nvidia graphics driver (version 390):

Xorg (7) /lib/x86_64-linux-gnu/libgcc_s.so.1+11ba4 → /lib/x86_64-linux-gnu/libc-2.27.so+165f21 → /lib/x86_64-linux-gnu/libgcc_s.so.1+12da5 → /lib/x86_64-linux-gnu/libgcc_s.so.1+f373 → /lib/x86_64-linux-gnu/libgcc_s.so.1+10550 → /lib/x86_64-linux-gnu/libgcc_s.so.1+1138c → /lib/x86_64-linux-gnu/libc-2.27.so+131168 → /usr/lib/xorg/Xorg+1b88ad → /usr/lib/xorg/Xorg+1bc649 → /lib/x86_64-linux-gnu/libpthread-2.27.so+12890 → /lib/x86_64-linux-gnu/ld-2.27.so+fe47 → /lib/x86_64-linux-gnu/ld-2.27.so+1770a → /usr/lib/xorg/modules/libwfb.so+25597 → /usr/lib/x86_64-linux-gnu/nvidia/xorg/nvidia_drv.so+60a46c → [heap]+d35cb0

That's something which isn't open source but hopefully a future update from Nvidia will resolve it.

If the cause of the crash is in the open source parts of that stack trace, we can't tell, unfortunately.

CurrentDmesg.txt:

[58189.152330] PM: suspend exit
[58189.162027] Read-error on swap-device (253:0:361608)
[58189.167038] Read-error on swap-device (253:0:361672)

"People die when they are killed". Specifically "Read-error on swap-device" kills you with SIGBUS. Mystery solved.

I really expect if you looked at the crash, you would notice it is SIGBUS, with si_code == BUS_ADRERR (2). This means a read error when trying to load a page of virtual memory back in from swap or from the filesystem.

There's a common bug which matches this, so please read #1776887
"Critical upstream bugfix missing in Ubuntu 18.04 - frequent Xorg crash after suspend".

I'm sure this applies to at least some users who marked themselves as affected, or some duplicates of this bug. This particular kernel log includes some other errors as well though, so I can't rule out that they also have some relation.

Status changed to 'Confirmed' because the bug affects multiple users.

[Karl Kastner (kastner-karl)]

This happens to my XMG/Clevo W230s with GM107M [GeForce GTX 860M]. I have an external monitor connected and disable the laptop screen with xrandr --output eDP-1-1 --off. When I suspend and close the lid, then disconnect the VGA cable and therefafter resuspend, Xorg crashes and I have to login again. It also kills screen sessions running in the background. This seems to be related to bug #1421808

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

Ubuntu 18.04 (bionic) reached end-of-standard-support on May 31, 2023.

I'm setting the status of this bug to 'Incomplete' as it's not seen any activity for some time. If this is still an issue when using a currently maintained release of Ubuntu then please let us know which one(s) otherwise this bug report can be left to expire in approximately 60 days time.
