XLib warning printed to terminal on application close #1160

Open Jacalz opened 4 years ago

Jacalz commented 4 years ago

Describe the bug:

It looks like https://github.com/fyne-io/fyne/pull/1153 accidentally introduced a weird Xlib error on application close. I don't know why I didn't notice it when testing the PR though. Seems to just be a warning and not something that break anything as of now, however it would be good to get rid of it :)

To Reproduce:

Steps to reproduce the behaviour:

  1. Use an Nvidia GPU on Linux and close the application.

Screenshots:

Xlib:  extension "NV-GLX" missing on display ":0".

Example code:

It works fine to test this using fyne_demo.

Device (please complete the following information):

Is this still present on 1.3.2?

Jacalz commented 4 years ago

Yes I can still replicate this on the latest tag in the develop branch.

andydotxyz commented 4 years ago

Is it at all like this issue? https://askubuntu.com/questions/67567/how-to-fix-error-xlib-extension-nv-glx-missing-on-display

Jacalz commented 4 years ago

Nope. This is a desktop computer. I guess I could technically could force the intel iGPU to be turned off in the bios but I very much doubt that it would make a difference as I am using the Nvidia GPU and nothing else.

andydotxyz commented 4 years ago

Sorry I wasn't suggesting tweaking the hardware, was just trying to figure some more out. Which graphics driver is X using?

Jacalz commented 4 years ago

I didn’t think you did. I just added my thoughts and I guess that they came out a bit wrong 🙃

It should be using the proprietary Nvidia driver 450 or possibly 380, but I will need to double check that when I have time 😅

I'm also getting Xlib: extension "NV-GLX" missing on display ":0" on close. I'm also on Solus. Is this a Solus-specific thing? Any fix for it?

This is present on Fedora Workstation 33 running Gnome Shell 3.38.2 and nvidia 455 driver via dnf xorg-x11-drv-nvidia.x86_64 3:455.45.01-1.fc33 @rpmfusion-nonfree-updates

Confirming this is still present on Ubuntu 20.04 LTS (linux/amd64) running Gnome 3.36.8 and nVidia driver 390. Go version 1.16.5 and Fyne version 2.0.3

Exact error text is: Xlib: extension "NV-GLX" missing on display ":1"

Everything looks fine in the app (graphics-wise). The warning on os.exit is just unsightly is all. Hope that helps.

I'm seeing this as well on Ubuntu 18.04

Also present for :0 on gentoo with nvidia-drivers-515.65.01 and x11-libs/libxcb-1.15-r1. Edit: I ran it for you with strace.

It looks like this is the same problem for Manjaro (with X11 and Nvidia GPU).

andydotxyz commented 3 weeks ago

Does the system also have an integrated GPU?

Jacalz commented 2 weeks ago

I can't speak for anyone else here but FYI: When I initially saw this, it was on a desktop computer without an integrated GPU :)
