Could not initialize GLX

📱 Desktop & mobile clients

Hi,

I have been running nextcloud client for years on multiple platforms. However today, when I upgraded it on my RHEL8 Linux from flatpak, it won’t start any longer:

Could not initialize GLX

According to glxinfo, I do have GLX in my Gnome3 environment. Any ideas why it stopped workig after upgrade?

For me the problems seems to be ReadHat system related and not Nextcloud specific , because essential gtk components are missing. Have you tried to ask aunt G. for help:

It seems to be about Nvidia drivers. On my other rhel8, which has the same software setup, but not Nvida graphics card, it works fine. There is something how Nvidia glx stuff gets used through flatpaks. Need to figure out a bit further…

Likely I’d need to follow this guide to install GLX stuff into flatpak. https://www.linuxuprising.com/2018/06/how-to-get-flatpak-apps-and-games-built.html

Which doesn’t have the recent versions available. Well, this is what one gets using proprieatry drivers in open source systems. Avoid such if you can.

Could the nextcloud-client fall back to software rendering in case it can’t setup the GLX using display adapter acceleration? There is related issue here: https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/issues/350

there is solution to this here: https://github.com/flathub/org.freedesktop.Platform.GL.nvidia/issues/47#event-3939932692

sudo dnf remove nvidia-driver
sudo dnf module reset nvidia-driver
sudo dnf module enable nvidia-driver:450
sudo dnf install nvidia-driver
sudo flatpak install flathub org.freedesktop.Platform.GL.nvidia-450-80-02
sudo reboot
