Memory leak of 882-877 =5MB after hibernation?? Browser was in text-mode only. AND: they USA are so STUPID, **that** possibility under NOUVEAU the same error aroses!!!

They're so IMPOSSIBLY stupid, certainly... they do bad and good simultaneously, shits of hybrids... [ARURT-US!!!]

 •Test circumstances - [EDIT] I omitted copying certain param into „shadow” module subsystem... &... THE PROPER ONE.

„Clear” initcpio: no nvidia, no nouveau & /etc/modprobe.d/nvidia.conf filled-in.
And  NVreg_PreserveVideoMemoryAllocations=1 as copy from boot cmdline:

 

/etc/modprobe.d/nvidia.conf        :

...

 6 options nvidia  NVreg_PreserveVideoMemoryAllocations=1
 7 options nvidia_drm  NVreg_PreserveVideoMemoryAllocations=1
 8 options nvidia_modeset   NVreg_PreserveVideoMemoryAllocations=1
 9 options nvidia_uvm  NVreg_PreserveVideoMemoryAllocations=1
10 

....

end

Standard GLX info program [EDIT — that is, before the 1-param duplication from cmdline...]:

ZRAM&HIBERNATION w/swappiness value of 50 good for Brave and several other BIG apps (SIMULTANEOUSLY!)

Startup often quick, sometimes swap op going on along relatively short timespan.

THUS:

It makes NO sense to hear „specialists” saying 80, 100 or... „even” above 'd be.... . Its false, I performed several hibernations, monotonic uptime so far 4+ days.

Closing of SMALLER applications before hibernation.

With ≈3 GB of RAM, I must control some smaller unnecessary applications – before (complaining) s2disk. But after shutdown of something, the rest process is OK.

Thrash-protect Python script has been turned off during test.

It isn't as useful, maybe not a bit!!!
