Rust LSP error when not using "real" terminal

[kedare]

I have been trying to use the rust LSP

It works fine when using nvim from a terminal,

But when trying it using different frontends like goneovim or neovide, the LSP initialization fail with the following error

I'm not sure if I should open the issue here, in neovim, LSP or Rust LSP project. Let me know if I should put it somewhere else

Thanks

Launch with a configuration file and see if you get errors.

neovide -u NONE

If it still errors, you can rule out LunarVim.

Also run :checkhealth to make sure there are no glaring errors.
Some versions of neovim 0.5 are still buggy. If you haven't already, try compiling a newer version of it.

Neovide won't start with the given command

neovide -u NONE

What is the -u doing exactly ?

From the checkhealth, I see that the RPC part is failing on GUI (timeout) and working on TUI.

The -u flag tells neovide to start with the given config: NONE. It's starting up with no configuration files at all.

Do you have a graphics driver installed? Neovide relies on graphics acceleration for performance gains.

The error is suggesting you type the following in console

sysctl dev.i915.perf_stream_paranoid=0

[kedare]

I do have GPU acceleration (working fine on other applications), I ran the sysctl before trying again but I am getting the same issue, should I ask directly in the neovide repository ?

EDIT: Found the issue neovide/neovide#527

When opening with neovide -u NONE it opens fine, but of course I don't get the rust syntax/completion properly when opening a rust file (so no error like before as it is not doing anything)

Do I have any way to know which line of code/configuration triggers this error ? (the initial one on the screenshot), I suspect it is coming from lspconfig but I am not sure.

I'm not sure what's going on but I think the key to figuring it out willl be the line. home/mpoussin/.cache/yay/neovide/src/neovide/CARGO/git/checkouts/skribo-3c422fce25a33836/a35c876/src/collection.rs:130:32

Try starting from a different, fresh directory and seeing if it still fails. Looks like neovide is storing something in a cache file.

#269

[kedare]

For the neovide issue, I could get it working by following neovide/neovide#527

Installing a specific font fix the issue (noto-fonts package on arch)

But I still have the initial issue (not a terminal, from rust rls), I could not find a way to find from where is this error coming exactly ?
