VRR Issues after waking from sleep.
Hello I'm running bazzite-deck on my HTPC. It's connected via a certified HDMI 2.1 cable to a LGC3 (that doesn't have a displayport). I run in game mode pretty much full-time.
The system is a AMD 7600 cpu and a AMD 6650XT. I generally "turn off" they system by holding down the xbox button on my controller and picking sleep from the steam menu that pops up.
When the computer wakes back up, the TV constantly flickers black each time a menu item moves for about a second or so. My TV reports that the framerate is "40fps" for some reason. I can struggle through it to get to the QAS menu and disable and re-enable VRR, and then everything goes right back to normal.
I'd love some help solving this as its quite annoying. I'll be happy to send some logs or more information, but I'm not sure exactly what would be useful.

There's a huge DRM refactor coming to gamescope here soon
may resolve this issue
youir gamescope logs (saved to ~/ as a dotfile) would also be helpful
there's two of them
hopefully these are what you are looking for
I was told Jan's HDR patch causes issues with vrr
@Jan whereas the chimera one doesnt

linux-handheld/6.6/0001-HDR.patch at master · hhd-dev/linux-handheld
Arch based kernel optimized for the Legion Go and Steam Deck. - hhd-dev/linux-handheld
On the ally at least
Chimera dropped their HDR patches some time ago AFAIK
the ones I currently use are based from nobara, with are baed on the CachyOS patch
and I don't really see anything vrr related in the patch
can you perhaps point me at an upstream I should consider
i was told that swapping to this patch fixes it
thats all i know

AMDGPU HDR patch causes issues, possibly involving my VRR display ·...
I have a Radeon RX 6700-XT, and two monitors: An LG 24UD58-B, which is 3840x2160 panel that supports up to 60Hz and supports optional VRR range of 40-60Hz, and a Dell P2414H, a 1920x1080 panel that...
that would break the LGO again though
lol
so, removing it fixes it
but... its not just part of the HDR patch
and probably the SD OLED
its also part of the steamdeck quirks fix
well, unless I find out more I can't really act
I'll talk to GE regardless
For reference
Chimera dropped their HDR patch 3 months ago

could always make this a DMI check
true should only apply to Galileo/Jupiter/LGO, otherwise call the old func
I can look into that later today
indeed, but I sadly lack enough info to make a decision
iirc the VRR = true thing is a hack for gamescope to manage frame timings
which it does when it has full refresh rate control of a display that is otherwise not a VRR display
so outside of gamescope its probably broken
works fine for me, but maybe there's some edge cases
gamescope only does this for specific hardware, hence my DMI check concept
i think i tested the patch and it was fine?
but maybe not
do you perhaps know anyone I could talk to to get more info on this
you have common servers with neither of them
_neroreflex_ adolfotregosa
adolfos legion go is on order so he will be able to confirm if the patch messes with the go in a couple of days
all of their testing was done on the ally so if you wonder about the go they wont be much helpI thought a bit about the issue and think the current approach of just forcing vrr on is broken especially on systems without vrr support and compositors that aren't intended for it
the steam deck hw quirks patch appears to include it for gamescope specifically, but is not a suitable solution for Bazzite where running anything but gamescope is an expected use-case
I am unsure what the best solution would be without also modifying gamescope
forcing vrr on was done for the go and the sd oled, not the ally
in kernel
no, it was done everywhere
because the displays have some weird timing requirements
yes
but it was done specifically for those 2 devices
yeah
and since the Deck is only expected to run SteamOS, where you either run gamescope or KDE nested in gamescope, its not an issue, since gamescope supports VRR just fine
but for other compositors this would cause problems
yknow what, I know how to go forward with this...
If you think that this has to do with vrr you don't understand the issue
Also desktop mode on the deck is not nested I think
I recall hearing that they switched Desktop mode from just being a raw KDE instance to being KDE nested in gamescope to allow for overlays and what not
Both should be available
Nested does not allow for multi monitor and has stupid docking bugs
both are offered
nested KDE & normal
as far as what you mentioned -- my patch I sent should be enough
since it only applies this VRR tweak to hardwre we know needs it
I looked at the patch again
the oled hw quirks patch also reverts all but one segment of the vrr stuff
so nothing is doing VRR
Not true
That was for debugging at the time. It got added later again
Then please help me find it
Its not on master
It's just GE's patch from nobara
That is just kept in sync with torvalds tree
Ah
Well, it can't be an up to date patch from nobara because nobara uses 6.7
And 6.7 had HDR partially upstreamed so the patch doesn't apply
Older version then 😉
Indeed, but rebasing should not be too bad right?
Anyway, 6.8 has almost everything in anyway so I just decided to skip 6.7
