The UI crashes after suspend

[Plamen Tarkalanov]

All was working OK until I installed nvidia cuda drivers.
Afterwards on lid open the system crashes.
On lid close it exhausted the battery too fast.

Now I have them deleted and have reverted to nouveau drivers but the problem persists.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

I wasn't able to submit a crash report as I didn't find any.
After some browsing and reading of logs I narrowed it down to this bug - https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1933880
I applied a certain workaround which kind of fixes the issue.
Now restoring is ok, though it freezes for few seconds but the application state is presereved.
