High VRAM usage when i wake up my screen

abro2072 · Yesterday 03:18:28

fresh arch install with everything up to date, im on kde plasma 6, mesa 26.0.4, when i wake my screen up from being turned off my vram usage spikes to 100 and the only thing to fix it seems to be changing the refresh rate. ive tried using cvt -r to no avail as im trying to overwrite the refresh rate/resolution im using. ive googled stuff all day but i cant seem to get it fixed. any tips to point me in the right direction would be amazing

is that an actual problem (i.e. do you have a performance degradation when trying to use something that invokes the gpu?)/what are you looking at that measures this? Which GPU are you talking about? That RAM/caches are getting used is not inherently cause for concern and especially iGPU amd implementations tend to "keep caches" that will be automatically dropped once something actually starts using things.

From what to what?
Is it the rate specifically or does any mode switch (resolution change) help likewise?
vram as measured how exactly?

wake my screen up from being turned off

DPMS, monitor powered off or is the screen also locked? Do you wake up from S3 at this point?

im using lact to monitor it, im on a 6700xt with mesa 26.0.4, the only degredation i can see so far is high power draw from 8 or 9 watts to over 20 and higher gpu temps even when idling at the desktop with nothing else open. ive looked up a bunch more stuff since last night and i think its got something to do with either adaptive sync (which sucks on kde plasma for me, flickering out the ass) or reduced blanking timings. im looking into using cru on windows to create a modeline for my edid file. but if you have any other tips to try lmk, ty g

doesnt matter the refresh rate cause itll revert to 119.99hz and be fine
ill have to look into dpms as i didnt know about that, thank you for your help g

i think its got something to do with either adaptive sync

Can you disable that in the monitor?

ooking into using cru on windows to create a modeline

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; done

You'll need https://archlinux.org/packages/extra/x86_64/v4l-utils/
