[nvidia] gnome-shell GUI freezes totally

[Sami Kuisma]

I'm using basic Ubuntu 20.04 and GUI (gnome?) freezes totally.
- I was running Firefox 78.0.2 and watching Youtube. The video and sound stopped.
- Keyboard was unresponsive, can't get into console, and for example pressing caps lock/num lock didn't toggle keyboard leds.
- mouse didn't move.
- The whole computer and OS didn't crash I suppose. I could ping the computer from another computer. and there were entries in /var/log/syslog after the GUI freeze.

What ever happened I can find some indicating in /var/log/syslog:

Crash happened 14:21 local time which pinpoints the bug into these entries:

Jul 16 14:21:24 Aorus-Ultra-Ryzen gnome-shell[897367]: [Child 897367, ImageBridgeChld] WARNING: failed to open shm: Too many open files: file /build/firefox-k3d8Rk/firefox-78.0.2+build2/ipc/chromium/src/base/shared_memory_posix.cc, line 246

after that anything GUI, keyboard or mouse related was totally unresponsive.

there were other entries in syslog after that, and ping worked into this frozen machine. So the whole OS didn't crash. Only GUI related.

I hope this helps.

I'm sure this is a bug. The same effect has happened 3 times in 30 days. I didn't check the previous syslog which error message there was.

Please:

1. Run this command to send us more info about the machine:

   apport-collect 1887821

2. Next time the problem happens and you have to reboot, please then run:

   journalctl -b-1 > prevboot.txt

   and attach the resulting text file here.

3. Check for crashes by following *all* of these instructions:

   https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

[Daniel van Vugt (vanvugt)]

Also...

4. Run this command:

   lspci -k > lspcik.txt

   and attach the resulting text file here.

5. If the problem is just the machine running out of memory then please track that using the 'free -h' and 'ps auwx' commands and find out which process is using the most memory.

[Sami Kuisma (sku-8936)]

ok, here is prevboot.txt

it was too big, over 8M lines, because of one buggy sw; Interactive Brokers TradeStation floods the log.

wc prevboot.txt
  5089905 91689782 962690406 prevboot.txt

with entries like this:

head prevboot.txt
-- Logs begin at Tue 2020-07-14 17:11:55 EEST, end at Fri 2020-07-17 07:38:59 EEST. --

So I removed those tradestation lines and resulting prevboot is 8203 lines

The log in comment #4 is missing the time from when the machine booted, which I also wanted to see, but maybe that doesn't matter... Near the end of the log it seems your system is running out of file descriptors AND running out of memory. So I suggest you dig deeper to find out which process(es) are using all the memory and files. Some commands that may help:

  free -h
  ps auxw
  lsof

"The log in comment #4 is missing the time from when the machine booted, which I also wanted to see, but maybe that doesn't matter..."

the uptime was 16d and system didn't have logs from the boot time.
the log had everything created by 'journalctl -b-1 > prevboot.txt' except grep -v 'install4j_17tjtje-tws.desktop' lines

The system hadn't been running low on memory for days, unless it didn't happen very suddenly because of some bug in firefox etc. I have 64GB and using roughly 20GB for days (I have top/htop running in terminal all the time). I am typically aware of mem usage.

as far as I know that CRASH file wasn't created.

- nothing in /var/crash
- nothing recent in https://errors.ubuntu.com/user/e003a24bbaa04f1c5883029a977e36cc1f8f31ebf57b3f3df099cf9cb7d38bb43d671c6a7a2a6376d5385e8c7cbfe0f060bada6610fa542eb5f571a1fadd9fee

if the GUI process hadn't yet crashed, just frozen. as I couldn't get into console (keyboard didn't work) I pressed the reset button in computer. And there wasn't any crash file existing.

Now I installed ssh server, and if the gui freeze happens next time, I can log in from another computer and see processes which is hung, or hogging CPU or mem. The GUI freeze has happened 3 times since initial OS install about a month ago.

Same sort of total freeze again. GUI totally frozen, while watching youtube video in firefox.

[Sami Kuisma (sku-8936)]

frozen before timestamp Sep 2 21:07:30 (which was next reboot)

[Sami Kuisma (sku-8936)]

could the freeze be something GPU related?

Sep 2 21:04:51 Aorus-Ultra-Ryzen kernel: [935088.204347] NVRM: GPU at PCI:0000:09:00: GPU-1aac77c3-3e8f-aca5-1c8e-19e660d74551

the system froze around 21:05 (next reboot was 21:07:30)

[Daniel van Vugt (vanvugt)]

It's suspicious the problem in comment #10 occurred as the Nvidia driver was starting. Also that seems to be an odd version of the Nvidia driver we don't distribute.

If you installed the Nvidia driver manually then please uninstall it and then use the 'Additional Drivers' app to install a supported version.

If you installed the Nvidia driver from an older Ubuntu update then your system is out of date and needs updating now. So run:

  sudo apt update
  sudo apt full-upgrade
  Reboot.

same sort of crash again.... while watching youtube on firefox

might again refer to GPU

last lines in log:

[Daniel van Vugt (vanvugt)]

The messages you refer to are not a crash. And you still have an unsupported version of the Nvidia driver installed. Please follow the instructions in comment #14.

I have the same issue on my PC. The gui expected the mouse freezes randomly.
