Hanging at startup on x11 (just after switching from a wayland session)

nickdiego commented 5 years ago

Description:

Not sure if it's something specific to termite (maybe happens to other GTK apps). After switching back from a wayland session (e.g: Gnome on Wayland, Sway, etc) to i3, for example (with no DE), and trying to start termite it gets stuck at startup. Analyzing its strace, I saw this:

 894 socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC, 0) = 3

5713 poll([{fd=3, events=POLLIN}, {fd=5, events=POLLIN}, {fd=11, events=POLLIN}, {fd=13, events=POLLIN|POLLPRI}], 4, 600

Workaround:

Setting GDK_BACKEND explictly to x11 works around the issue:

env GDK_BACKEND=x11 termite

System info:

Arch Linux - Kernel 4.19.13-1-lts
Termite: 14-2
Gtk: 3.24.2+7+g43aeb52b73-1
vte-common: 0.54.3-1

I'm trying a "snap" package of termite and am also running into this problem. In my case, explicitly setting the GDK_BACKEND doesn't fix it. It seems that only Wayland backend is considered, but I'm running under X11.

Here's the Snap package I'm trying: https://build.snapcraft.io/user/sd-hd/termite-snap

Termite is obsolete. Please use Alacritty instead. See https://github.com/thestinger/termite#termite-is-obsoleted-by-alacritty for more details.
