If you log in again after the resume, you should hopefully see be able to a crash message if you look at the end of
/var/log/Xorg.0.log.old, or possibly$HOME/.local/share/xorg/Xorg.0.log.old. That is, in the Xorg log file from your previous login.There is a particular known issue on Ubuntu 18.04, which I think matches everything you describe. It generates crashes at many different locations, but it also has quite a distinct feature. The crash always occurs with a SIGBUS signal - "bus error" - which is quite unusual (on common Intel/AMD-style x86 cpus).
Most crashes occur with the signal SIGSEGV ("segmentation fault") or SIGABRT (assertion failure / abort). SIGSEGV is the common error for accessing a null pointer or wild pointer, particularly on x86. Note that for SIGSEGV on x86, Linux logs a "segfault" message, which would have appeared in the system log. This SIGBUS crash often doesn't leave a distinct signature in the system log! So already I am suspecting the known issue. Since you are using software affected by this nasty bug, I would suggest you look at it and see if you can rule it out by testing one of the suggested workarounds. But I'm not sure if that answers the general sense of your question.
There are a couple of different messages which sometimes occur with this SIGBUS crash. If you wanted to, you could search through all your historical logs and see if you had any "Read-error on swap device", or any "Buffer I/O error". E.g.
zgrep -C5 /var/log/kern* "Read-error".Note that Xorg logs its own crashes but this is quite an unusual thing for software to do. It tries to catch crashes, logging the crash signal and where they happened in the code, including the full chain of function calls that led up to it. In theory, the call-chain might be something useful to search for other reports. Unfortunately when I've tried to rely on this, the call-chain logged by Xorg seems to be inaccurate, and can look basically the same for problems which are actually different.
To capture crash location it is more reliable to use a general-purpose system such as Ubuntu Apport or systemd-coredump. I'm familiar with the latter. If you installed
systemd-coredumpit would capture a full coredump of the crashes and allow you to inspect them usingcoredumpctl. Installing systemd-coredump would remove Ubuntu Apport though.Unfortunately I don't use Ubuntu, and I know very little about how Apport behaves. I read that the full Ubuntu Apport isn't enabled by default on stable releases. Specifically, I think stable releases do not enable the feature that lets you create bug reports which could be searched for on the open web. Clearly, enabling it would take you longer than using the
Xorg.log, and it will reduce the number of people who report using this method. So if theXorg.loginformation is not 100% accurate but is distinct, it is possible you might have more luck searching for reports of crashes using theXorg.loginformation, even where it is not accurate.It is surly NVIDIA driver or NVIDIA proprietary driver compatibility issue with Ubuntu kernel.
I am having NVIDIA 740M GPU on laptop and I was facing same issue. Whenever I used to put down laptop lid or used to suspend laptop then upon resuming X was failing to turn-on. and some time it is used to show error something like
But when I turned off the NVIDIA GPU from BIOS I am able to suspend and resume OS smoothly
