--- Comment #61 from Nate Graham <n...@kde.org> ---
Thanks everyone. So I brought this to the attention of a KWin developer who
brought it to the attention of an NVIDIA developer.
The conclusion here is that NVreg_PreserveVideoMemoryAllocations=1 is not a
workaround, and *should be* used. The only reason it's not turned on by default
is because if it's turned on without the appropriate pre-suspend hooks in
place, suspend will get broken. NVIDIA distributed systemd unit files for these
hooks, but they don't trust distros and users to install and activate them, and
of course those using non-systemd distros will have to figure something else
out as well. So they leave it off by default to avoid having to handle those
cases.
This information has been added to
https://community.kde.org/Distributions/Packaging_Recommendations#Proprietary_NVidia_driver_configuration,
and I've emailed distros about it.
So from a KDE perspective this is basically a downstream/distro issue at this
point. I encourage everyone to go contact their distros about it as well, and
ideally submit patches if you're a distro packager or like to play one on TV.
