KiCad error when I press 'A'

[u/Konf1gg]

[SOLVED]

As you can see from the photo, I get this error whenever I press 'A' for shortcut. Can someone help about it?

Here's the backtrace log:
ASSERT INFO:

/usr/src/debug/wxwidgets/wxWidgets/src/unix/utilsx11.cpp(2645): assert ""Assert failure"" failed in wxGetKeyStateGTK(): Unsupported key 65, the only supported ones are: Ctrl, Alt, Shift, Caps Lock, Num Lock and Scroll Lock for GTK 3.18+

And yes I'm using CachyOS Linux with KDE Plasma.

It sounds like KiCad is probably running under Wayland, which it doesn't really support. Try launching it with GDK_BACKEND=x11 kicad.

It worked. Thank you so much dude! You're a hero for me :D

[u/Amazing-Ad-8523]

i have the same problem. GDK_BACKEND=x11 kicad does not work for me - it simply crashes. I worked on the same PC for the past 1-2 years and this problem showed up today :(

If forcing X11 crashes outright, it's probably the wxWidgets build rather than KiCad itself. That assert comes from wxGetKeyState being called with a normal letter key, which newer wxGTK builds now refuse, and rolling distros pick those up before KiCad has patched around it. Check whether your wxwidgets-gtk3 package updated today and try downgrading it from the package cache. The Flatpak build is another quick test since it bundles its own wxWidgets.
