Regression between v0.168 and v0.169, crash due to `PlatformNotSupported`

Open ruuda opened this issue 9 months ago • 2 comments

Summary

I used to be able to run Zed on my Dell XPS 15 9510, but recently it refuses to start. Bisecting shows it broke in v0.169 due to #20853, which I suppose is an intended side-effect of that change.

Steps to trigger the problem:

  1. zeditor --foreground

Actual Behavior:

[2025-03-02T19:12:56+01:00 ERROR zed::reliability] {
  "thread": "main",

}

Expected Behavior:

The editor starts.

After bisecting, the first bad commit is 298b9df589c2be910676b59cb8213f98a8396fed, introduced in #20853. There is some discussion there that it breaks Intel + Nvidia systems … well, the Dell XPS 15 9510 is apparently one of the affected systems. I don’t use the Nvidia GPU though, and I blacklist the nvidia and nvidia_uvm kernel modules in /etc/modprobe.d; everything runs fine on just the integrated Intel graphics. (It is possible that something recently changed on my system — I tried loading the module to see if it helped Zed to start, so during the bisection process it was loaded, but I think I just haven’t used Zed since mid-December on this laptop.)

I have a different, slightly older Dell XPS with Intel + Nvidia GPU, and Zed runs fine on that laptop. (I think I don’t have the Nvidia drivers installed at all on that one, but I’m not sure from the top of my head.)

I suppose this breakage was expected, though it would be nice if I could run Zed again. No other software I use (Gnome desktop, editors, IDEs, browsers, video players, games) has issues with the Nvidia GPU being present in the laptop. I’m happy to help diagnose this further.

Zed Version and System Specs

Zed: v0.168.0 (Zed Dev 56d20fc0a3854ef6fa60aa30470ff985041964c9) OS: Linux Wayland arch unknown (It’s kernel 6.13.5-arch1-1) Memory: 31.1 GiB Architecture: x86_64 GPU: Intel(R) UHD Graphics (TGL GT1) || Intel open-source Mesa driver || Mesa 24.3.4-arch1.1

Thanks for running the bisect and connecting this to #20853. Also, seems like you're not the only one affected by this :(.

From the original PR, it seems that updating your drivers may help? Could you or @vinifrancosilva confirm if that helps either of you?

I'll also take a look to see if we can add some way to tell Zed which GPU to use/not use (so you don't have to blacklist the kernel modules in modprobe.d)

Maybe @kvark has some input on workarounds here as well?

Would be great to see the logs! Dell XPS 15 is quite a popular piece of hardware, so I'd love to get it fixed.

There is nothing much interesting in the logs though:

Is there something I can run to pin it down more specifically?

Could you add blade_graphics=debug to your RUST_LOG? They have to be explicitly enabled

Sure! I built in debug mode this time as well, in case that helps to uncover anything.

Logs from one run built from 387281fa5b4e6b0f3cb629d1f889c4eae9d1b0ab, this time with blade_graphcis=debug

It seems also that my blacklist nvidia and blacklist nvidia_uvm lines in /etc/modprobe.d are ineffective, lsmod shows both being loaded, as well as nvidia_modeset.

@ruuda Looks like this is a relatively modern GPU (NVIDIA GeForce RTX 3050 Ti Laptop GPU) with a recent driver 575.57.08 and your I think your Mesa (>24) is new enough that this should be supported.

GPU: Intel(R) UHD Graphics (TGL GT1) || Intel open-source Mesa driver || Mesa 24.3.4-arch1.1

that this should be supported

Do you mean ‘should’ as in, it ought to be supported, but it is not currently, or do you mean that you expect Zed to already work on my system? It did work until 298b9df589c2be910676b59cb8213f98a8396fed, when what looks like an intentional change related to Blade broke it.

Now that you mention it, I tried again with latest main (de0e6f716c10e97b06423519f57487db176a6df9). The logs have changed:

Zed failed to open a window: Failed to create surface: PlatformNotSupported. See https://zed.dev/docs/linux for troubleshooting steps.

Following the steps at https://zed.dev/docs/linux#forcing-zed-to-use-a-specific-gpu, it lists my GPU as

$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation TigerLake-H GT1 [UHD Graphics] [8086:9a60] (rev 01)

and running Zed with ZED_DEVICE_ID=0x9a60 does work!

Still, it would be nice if it worked out of the box like it did before, no other text editor I use requires me to set environment variables just to get a window on the screen.

I meant should as in we knew that change would break support for some older drivers/graphics hardware and that failure was somewhat intentional; given your hardware/drivers we should try to fix things so Zed works, Glad to hear it's working with you when you force the Intel card -- still not sure why it's not working with the NVidia.

I'm going to move this to a discussion.

There isn't anything immediately actionable here, other users are able to use these devices without specifying ZED_DEVICE_ID=0x9a60 -- not sure the specifics of your hardware/ distribution/configuration which are triggering this behavior, but at this stage it's not something we can allocate resources towards nailing down the issue. Sorry.

Happy to revisit if you (or anyone else) has suggestions for how to proceed.
