Describe the bug / provide steps to reproduce it

Context: PopOS, Intel Arc A750 GPU.

Upon opening Zed I get the "Unsupported GPU" message, stating that I'm currently using software emulation, with a link to the troubleshooting guide for Linux. I follow the link, used MESA_VK_DEVICE_SELECT=list zed --foreground to get a list of GPU devices. I see two devices:

MESA-INTEL: warning: cannot initialize blitter engine
selectable devices:
  GPU 0: 8086:56a1 "Intel(R) Arc(tm) A750 Graphics (DG2)" discrete GPU 0000:03:00.0
  GPU 1: 10005:0 "llvmpipe (LLVM 15.0.7, 256 bits)" CPU 0000:00:00.0

So I grab the device code 8086:56a1 for the discrete GPU, and run export MESA_VK_DEVICE_SELECT="8086:56a1" (I've tried with single quotes and no quotes, and gotten the same result)

I verify that it is in the environment by running

$ echo $MESA_VK_DEVICE_SELECT
8086:56a1

Then run zed, which gives me the same error as before.

Environment

Zed: v0.146.3 (Zed)
OS: Linux X11 pop 22.04
Memory: 31.2 GiB
Architecture: x86_64
GPU: llvmpipe (LLVM 15.0.7, 256 bits) || llvmpipe || Mesa 24.0.3-1pop1~~1711635559~~22.04~7a9f319 (LLVM 15.0.7)

If applicable, add mockups / screenshots to help explain present your vision of the feature

If applicable, attach your Zed.log file to this issue.

Untested, but can you try adding a ! to force its usage?

export MESA_VK_DEVICE_SELECT="8086:56a1!"

https://docs.mesa3d.org/envvars.html#vulkan-mesa-device-select-layer-environment-variables

natemcintosh · 2024-08-01T17:16:14Z

hmmm, interesting, now nothing happens at all when I attempt to open zed. I'll try re-installing and see what I get

natemcintosh · 2024-08-01T17:22:23Z

after a reboot, I was able to open zed just by clicking on the app icon, and received the "GPU not supported" warning. Then I shut it down, set the env var with the ! as suggested, and ran zed from the command line, which returned immediately and did not open zed. I also can no longer open zed by clicking on the app icon.

notpeter · 2024-08-01T17:34:09Z

Ouch. Can you confirm there are no copies of zed running in the background (ps aux |grep -i zed) and kill them if they are? Wondering whether something is causing a hung zed process to stick around preventing you from relaunching.

You might also try running zed --foreground to see what's happening or if it's crashing.

natemcintosh · 2024-08-01T17:54:46Z

Aha, looks like it is indeed running in the background.

~> zed --foreground
zed is already running

When I use ps aux |grep -i zed to find and kill the background tasks, I can start zed without having first set the env flag. But once I set the env var, it's back to the behavior of nothing showing up.

ViridianForge · 2024-08-06T05:18:48Z

I am able to replicate the invisibly running zed when adding the forced usage of MESA_VK_DEVICE_SELECT

> echo $MESA_VK_DEVICE_SELECT
8086:94a49!

I'm attaching my Zed.log from the run using the above just in case its helpful.

I had the same problem as you, and this fixed it.

If vkcube works fine and uses your dgpu, check if the file /etc/prime-discrete exists and has the contents ok\n. If it does, delete it.

I think Pop!_OS installs or sets up some nVidia stuff by default and throws Zed (specifically Zed's blade-graphics/src/vulkan/init.rs) through some loops.

I hope this helps!

ViridianForge · 2024-08-09T05:48:00Z

Thanks @lightningpwr28 - based on what you said, I also dug up this associated thread.

I went with switching /etc/prime-discrete from on to off and zed fired back over.

natemcintosh · 2024-08-09T12:58:28Z

This worked for me! my /etc/prime-discrete had the contents on\n, and I switched it to off\n, and now my GPU is used by zed! I guess this particular issue is a Pop!_OS particular issue for zed?

bwnjnOEI · 2024-08-13T11:36:11Z

Actually, I want Zed to run on Intel's integrated GPU rather than a discrete GPU (because I need to utilize the saved memory of discrete GPUs for such as model inference and training).

I tried this method from issue but Zed still runs on my discrete GPU.
I know that one of the goals is smooth encoding experience with using a discrete GPU, does it mean that Zed isn't allowed to run on integrated GPU?
