EGL error starting Flatseal

[aplatypus]

I am posting this as by way of a "watch for this" alert. I haven't decided that this is a problem on my workstation with MESA or if it's something to do with the Flatseal flatpak.

When I ran this tonight, I got the following error. I ran it from the command line as it keep hanging on start-up.

  $ flatpak run com.github.tchx84.Flatseal
libEGL warning: egl: failed to create dri2 screen
MESA: error: CreateSwapchainKHR failed with VK_ERROR_INITIALIZATION_FAILED
MESA: error: zink: could not create swapchain

The only thing I've found so far is that this deals with the display graphics stuff and that several underlying runtime packages have passed end-of-life and Flatpak has been prompting to have them updated or removed.

I reinstalled Flatseal which I'd hoped might restore any underlyin runtime issue. If it did that hasn't helped the problem.

system info

• Kubuntu 23.10, KDE Plasma over Wayland
• All apt and flatpak modules are up to date at this time.

The error that comes back on stderr is a bit obscure. It doesn't crash flatseal it just hangs but it seems that some underlying sub-process has crashed and nothing can talk to the main display.

Ideas welcome.

• Update your system and reboot
• Debug from flatpak run --command=sh com.github.tchx84.Flatseal
• Play with GDK_DEBUG, GDK_BACKEND, GSK_DEBUG, GSK_RENDERER.

[aplatypus]

• System updates completed, flatpak update completed to reported success.
• Is tehre some log I can enable or post here?
• I expect that I will not get far attempting to debug a program I have no knowledge of except to fire-up in the GUI.
  • Is there a project page or post some place with steps to get going debugging a flatpak app?
  • I don't know GDK_DEBUG, GDK_BACKEND, GSK_DEBUG, GSK_RENDERER (yet).
  • Good tips to follow-up at least up to my level of incompetence.
• I'm having flashbacks to the '90-s and DLL hell on Windows
  • Might be better that if an underlying runtime thing has contributed to the problem; can I force a clean install of flatseal for instance?

[rusty-snake]

My suspicion is that there is some kind of ABI mismatch between mesa in flatpak and mesa on the host. I know that there were issues like that in the past with flatpak.

GDK_DEBUG with some of the gl-* or vulkan-disable, GSK_DEBUG, GDK_VULKAN_DEVICE, GSK_RENDERER; GDK_BACKEND with x11 (force x11); may server as a workaround and to narrow down the affected library (libEGL, MESA, ... IDK much about them expect of being libraries related to graphic hardware).

[tchx84]

As @rusty-snake pointed out, this seems to be an system+flatpak compatibility issue. I would be very surprised if this is happening exclusively with Flatseal, and not with other GTK4 / Libadwaita apps.

For completeness, could you try another GTK4 / Libadwaita app? say https://flathub.org/apps/io.github.giantpinkrobots.flatsweep

I was able to test with a Intel graphics card today. The use cases I was able to exercise worked. flatseal for example worked.

Please refer to bug discussion: FreeDesktop :

• libEGL "failed to create dri2 screen" and coredump
• The latest indication is there is something Off with the NVIDIA driver. Unfortunately I don't have access to a second NVIDIA machine to compare the Intel graphics laptop with NVIDIA G-Force at this time.

The good news is that Flatseal is a-OK when working on an Intel (or non-NVIDIA??) stack at this point in time. Does someone have a different card to try???

For me the smoking gun for me is the core dump from the: eglinfo command (see below) ...

• I wonder if that command can be integrated into any bug testing when packaging a Flatpak tool???
  • The status from the failed eglinfo was: 134, btw-- Seems testable to me.

I would bet that, 134 means Core Dump or similar. Of coure it seems to be an NVIDIA related issue. It just seems helpful to include integration tests exercising essential dependencies say just checking exit states such as $? values >0 -- Would be mostly errors, mostly.

[proofy]

I have the same problem with a NVIDIA card in the notebook. How to test it?

[aplatypus]

@proofy ... It appears to be a Wayland (implementation) problem that is predominantly related to NVIDIA support on Linux.

Sadly i found that I have down-graded to Kubuntu 24.04, from 23.10 ... I lost (sanctioned) Wayland enactment. A lot of very important stuff became unworkable. So now, I'm back on X11. Poor show Ubuntu and Kubuntu from where I see it. The 23.10 stuff was may be 96% now it is 10% ... Looks as if the Neon distro(??) is my next update after a few hardware repairs.

BTW, the bug does not manifest on my INTeL graphics laptop. It is jut not fast.

[proofy]

Now, I found a solution for me. I have used environment variables

GTK_USE_PORAT=1
__GLX_VENDOR_LIBRARY_NAME=nvidia;
__NV_PRIME_RENDER_OFFLOAD=1

to run gnome programs correctly with X11.

With Wayland, I have to remove these environment variables and so Flatseal is running (to unset the environment variables).

[rusty-snake]

GTK_USE_PORAT=1

Should work without
