Hi all, I'm trying to make running hardware acceleration decoding on my old GeForce 210 (AKA GT-218, or NVA8 / NV-50 Tesla family). ---------------------------------- 02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT218 [GeForce 210] [10de:0a65] (rev a2) ---------------------------------- I usually used proprietary nvidia-legacy340.108 driver and it works quite well even if I noticed some A-V sync (or a bit of frame dropping) issues during video playback of some videos having 1080p and 60 FPS (h264 encoded). Those issues seem solved by turn off hardware decoding. With MPV player and closed nvidia driver I used options: "-vo=gpu -hwdec=auto" And it automatically chooses "vdpau" decoding. CPU rests on 5% of load and so on... But I read about good if not better performances of some nvidia cards by using Nouveau open drivers, especially for old GPUs which could have poorly updated/maintained proprietary driver. So I decided to switch to open ones. I'm using Slackware64-15.0 with multilib support. It runs kernel 5.15.38. I read on nouveau page about the need of some files extracted from proprietary driver, a closed firmware for video hardware decoding. On slackware it is provided by SlackBuilds community: https://slackbuilds.org/repository/15.0/system/nvidia-firmware/ It populated /lib/firmware/nouveau with variuos files I think related to my GPU: ---------------------------------------------- $ file /lib/firmware/nouveau/nva{3_{b,p,v},8}* /lib/firmware/nouveau/nva3_bsp: data /lib/firmware/nouveau/nva3_ppp: data /lib/firmware/nouveau/nva3_vp: data /lib/firmware/nouveau/nva8_fuc084: symbolic link to nva3_bsp /lib/firmware/nouveau/nva8_fuc085: symbolic link to nva3_vp /lib/firmware/nouveau/nva8_fuc086: symbolic link to nva3_ppp ------------------------------------------------------------ I also enable "nouveau" in /etc/X11/xorg.conf.d/20-nouveau ------------------------------------------ $ cat /etc/X11/xorg.conf.d/20-nouveau.conf Section "Device" Identifier "Nvidia card" Driver "nouveau" EndSection ---------- Here is env-var VDPAU_DRIVER defined to "nouveau" ------------------------------------------ $ grep -v "^#\|^$" /etc/profile.d/vdpau.sh export VDPAU_LOG=0 export VDPAU_DRIVER="nouveau" ----------------------------- On my system are installed: --------------------- libvdpau-1.4-x86_64-3 libvdpau-compat32-1.4-x86_64-3compat32 -------------------------------------- The second one is related to multilib environment.

But... But when I touch something, for instance "f" to enlarge to fullscreen, or "q" to quit MPV... Surprise! My system freeze, nothing work again, just the mouse cursor can still be moved around. No key combination works: ctrl+alt+F2, ctrl+alt+canc or so on... And it remains only to switch off by holding power button on the case. So no, it seems something goes wrong every time I try to use "hwdec". I also tried with different "pstate" modes, but it doesn't affect the stability: in any case hwdec lead to an unstable, and in fact completely locked screen. I'd like to use open drivers, but I'd like to take advantage of hardware decoding too, so that my CPU rests as quiet and fresh as possible. Is there some other suggest to configure some other aspect and try to achieve my scope? Or my tests are all I can do? So for hwdec is better to switch back to closed source nvidia driver legacy 340.108 ? Thanks in advance!
