555 release feedback & discussion

Graphics / Linux Linux
269

I have already responded once to this discussion, but my 555.58.02 driver version still has issues revolving around not being able to play audio & not being able to send signal through the DVI port for my second monitor to display anything.

I have sent this problem to NVIDIA via email with my log file, I have posted feedback about my problem yet I have not gotten any responses whatsoever & this issue for me has been going on for over a month. If anyone wants to help with my current situation, please respond to this post and ill give further technical info via the terminal.

This is getting really worrying to know if this problem will ever be fixed for me.

I can confirm that I get the exact error message on Unreal Engine 5.3.2 and Fedora 40 Wayland using the Nvidia 555 drivers

Problems in Wayland and Xorg

Ubuntu 24.10
Nvidia MX330, 550.120 and 560 drivers

Wayland:

When running in ā€œPerformance Modeā€, according to nvidia-smi, only gnome-shell is accelerated.

Xorg:

When running in ā€œPerformance Modeā€, folders on the Desktop canā€™t be opened. On-Demand works fine.

Nvidia syslog crashes. See attachment.

Can you please tell what program is that to view such data? Thanks in advance

274

Itā€™s software I wrote.

275

Is it open source? any links?

It is not and there is no links.

Basically you can see most of that with nvidia-smi or nvtop.
You can monitor BAR memory using:

 nvidia-smi dmon -s m

Hi there, using Ubuntu 24.04.01 I update my Nvidia driver to 555 (tried also 565) and when I run the command: ā€œnvidia smiā€ it notifies an error: "NVIDIA-SMI has failed because it couldnā€™t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
"

Feature parity? Open source driver can use nanosecond time as is only available for Linux open drivers. It also can use a Falcon RISC-V CPU in the GPU SOC to offload criticial for locality driver operations, like all the memory stuff. By default while closed source driver has to be enabled to use GSP.

Something not available even on windows 11 yetā€¦

281

The current state of the GSP implementation in the Open Source driver actually makes things worse. The closed source driver with GSP off gives the best performance.

If the GSP is adding unwanted latenices it might be very hard to fix but time will tellā€¦

282

No, the closed source with GSP on was giving better perfomance but that was a bug in closed source drive that was fixed.

GSP by defintion is decreasing latencies and thus allows true hetergenous memory. Also allows to (in the future) boot OS without the CPU.

283

I am still getting worse performance in some situations on the desktop and some games with open source driver / GSP On at least in 565. It has definitely improved massively, but from what I am seeing its still not quite there.

I mean, because its mostly on desktop use I see it now it could be related to issues in applications, or power management etc, but its definitely still an issue there.

Same for meā€¦ Open Source driver adds unwanted stutter over the closed driver with GSP off.

285

No, you did not get itā€¦ the same GSP in closed source driver was working faster than in open source driver. Open source driver only had GSP enabled. Closed source driver has to enable it. CSGO running smooth for a couple seconds, then HEAVILY dropping, then going back to normal, repeat Ā· Issue #335 Ā· NVIDIA/open-gpu-kernel-modules Ā· GitHub

I am not questioning that specific issue. I am saying that, closed source driver GSP on, and open source driver (so GSP) results in decreased desktop performance in some circumstances still now in my use. I suspect that it also still affects performance behaviour in some games, though I have not had a chance to investigate it fully.

So whether there is technical benefit to the driver using GSP, when GSP is used with either driver currently for me it results in problematic behaviour.

Sorry but no, GSP is on by default now in driver 555 and up, itā€™s in the beginning of the thread
