Arch Linux

I have an Intel i7 3770k with an Nvidia Geforce 750ti.

I have validated that I have the latest intel microcode update, latest nvidia drivers and latest version of gnome packages & mutter. Every attempt to login via Gnome/Gnome Wayland/Gnome Classic just returns to the login screen and dmesg will show the segfault in gtk-3 as posted in the original bug report.

I am able to log in and use my computer with KDE Plasma desktop. Gnome Desktop does not work.

Can't login into gnome (pushes back to login screen). I'm able to login another WM, like i3.

The fail whale screen (gnome-session-failed) crashing is most likely a red herring. Something must have caused the screen to be launched in the first place; perhaps the components that gnome-session attempted to launch crashed similarly.

That said, the fail whale screen shouldn't be crashing, either, so that's another issue.

In any case, please rebuild glib2 and gtk3 with debug symbols ( https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces up to installing the package) to get better traces.

I rebuild gtk3 with debug (download package from abs, edit PKGBUILD for debug option and build).
But I got some troubles while building glib2: 2 tests didnt passed, but this is may be another issue.

coredump after rebuilding gtk3 at attachment please

I reinstalled harfbuzz and harfbuzz-icu, same problem.

I completly switched from infinality to official: https://gist.github.com/cryzed/e002e7057435f02cc7894b9e748c5671
Command `gdk-pixbuf-query-loaders --update-cache` allowed me to login into gnome-session: https://bbs.archlinux.org/viewtopic.php?pid=1683313#p1683313

I switched from Infinality to Freetype2 and still had the problem of not being able to log into Gnome; however, I just ran the gdk-pixbuf-query-loaders --update-cache as given by Paste and now I am able to log into Gnome on Xorg using my Nvidia 750Ti! Thanks!!

Please edit the summary for more relevant searchs, ty

same issue, I can login with Wayland, but not on Classic and Xorg.

Don't focus on the backtraces. You're debugging the "Oh no something is wrong" screen that should show up when gnome can't start.

Look at journalctl logs why gnome-session is not working.
