Thanks for catching that. I'll try to include a fix with the upcoming 
uploads of the recent CVE series.

As I'm not that familiar with configuring systemd bits, do you know what 
would be the correct locations and contents to ship the fix?

If I read the documentation correctly, that should be

/usr/lib/systemd/system/systemd-suspend.service.d/nvidia.conf
===== 8< =====
[Service]
Environment="SYSTEMD_SLEEP_FREEZE_USER_SESSION=false"
===== >8 =====

and

/usr/lib/systemd/system/systemd-homed.service.d/nvidia.conf
===== 8< =====
[Service]
Environment="SYSTEMD_HOME_LOCK_FREEZE_SESSION=false"
===== >8 =====

Could you verify that this works (after unapplying your temporary solution)?


Thanks
