Anki crashes or freezes randomly

BlackBeans · November 5, 2021, 9:08pm

I recently changed my WM, and since then Anki crashes quite often.
Sometimes, with this error:

$ anki

Sometimes, it just hangs forever.

These bugs can start directly on launch, when clicking on a specific button or out of nowhere…

nouveau is known to be buggy, and you may have more luck with software rendering in the preferences screen.

BlackBeans · November 8, 2021, 4:15pm

Unfortunately, it is already configured as Software.

Not sure why you’d be getting that message in that case. Maybe installing nvidia’s drivers will help?

BlackBeans · November 9, 2021, 5:16pm

My new WM is Sway, which works under Wayland and does not work too well with NVidia proprietary drivers, unfortunately (although NVidia has promised improving compatibility), so for now I cannot use them.

Maybe the qt6 build will fare better? New toolkit and packaging test (round 2)

BlackBeans · November 12, 2021, 4:08pm

I am afraid I cannot try. This version of Anki is not packaged in my distribution (NixOS), and the packaging of Anki seems quite complicated (as seems to indicate this issue), and I don’t have enough time nor experience to do it by myself. I could try to copy the package for an other source, but the problem is that the NixOS packagers have stopped (for the time being) building Anki from source, and only provide the latest version through binaries.
Also, I cannot simply download the binary and try to run it because in NixOS, most programs need wrappers to be executed (due to non-standard path to libraries).

This seems a like deep-rooted issue which would require quite some time to be solved (the packaging story), so I guess for now I’ll simply use Anki from other computers, even though eventually someone (maybe me) will have to properly package Anki for Nixos…

The packaged version is mostly self-contained, so it’s worth at least trying it.

BlackBeans · May 24, 2022, 7:40pm

Now that I’ve mentioned this issue on an other thread, I remember where we were stuck: at the time, I couldn’t try out the newest Qt6 versions because they were not packaged. Well, now I can and it still hard crashes…
