Steam dumps core on first startup
I am having some trouble starting steam.
Since January 22 I am having some issues with steam (quite confident about that date, since steam is in my autostart and before it only appeared sporadically in the logs).
Steam did not start at all anymore, with the following entry in the journalctl:
Jan 31 12:20:32 nico-arch systemd-coredump[21382]: [?] Process 21187 (steamwebhelper) of user 1000 dumped core.
Stack trace of thread 21332:
#0 0x0000000000000000 n/a (n/a + 0x0)
ELF object binary architecture: AMD x86-64I thought, it may be to mis-configured grafiks, since I am not expirinecing other issues in the system.
I am having an Radeon RX 9070 XT and the ryzen integrated graphics chip.
After disabling the integrated grafics-chip steam fails on first startup, but stating it again works, also the performance is as expected.
The new core-dump seems to originate at linux-gate.so1, so I assume it is a kernel-issue (not sure if I understood the quick read about it that I had correctly)?

Re: Steam dumps core on first startup
you are quite a researcher, i must say
but first off back up all ur game saves
__kernel_vsyscall (linux-gate.so.1) does not mean kernel bug see this ->
#4 0x00000000f0d7606b n/a (libdbus-1.so.3 + 0xa06b)
#5 0x00000000f0da1762 _dbus_warn_check_failed (libdbus-1.so.3 + 0x35762)
#6 0x00000000f0da179d _dbus_warn_return_if_fail (libdbus-1.so.3 + 0x3579d)
#7 0x00000000f0d8e5de dbus_message_new_method_call (libdbus-1.so.3 + 0x225de) this means error dbus assertion or put into simple words - steam crashed itself intentionaly
still this aint much to work on but we can try a few thing here, backup saves,
pacman -Rns steamthen delete leftovers (~/.local/share/Steam & ~/.steam) and reinstall
sudo pacman -S steamu could also check for updates
sudo pacman -Syuanother thing u can do is use
STEAM_RUNTIME=0 steam and see if it works (native runtime)
and also try
DRI_PRIME=1 steam(igpu init check)
and try switching to x11 - has better steam support
u could also check on ur dbus
busctl --user statuscheck for missing libraries -
sudo pacman -S lib32-dbus lib32-mesa lib32-libdrm lib32-libx11if it still doesnt work - maybe flatpak steam is the way to go... (this btw)

Re: Steam dumps core on first startup
I see, thanks for the explanation regarding the linux-gate.so.1 and the advice.
Unfortunately the issue is not fixed yet. But also, I can just start the application twice for now.
I tried:
Deleting steam, purging leftovers, reinstalling leftovers (system was up to date)
No SuccessCheck missing libraries
sudo pacman -S lib32-dbus lib32-mesa lib32-libdrm lib32-libx11All installed --> No Success
STEAM_RUNTIME=0 steamFailed with many errors (steam-native-runtime is not installed)
DRI_PRIME=1 steamNo Sucess
busctl --user statusGives the following output:
BusAddress=unix:path=/run/user/1000/bus BusScope=user BusID=32ace68d71dac9caed94fdc223227b1e PID=1223 PIDFD=yes PPID=1 TTY=n/a UID=1000 EUID=1000 SUID=1000 FSUID=1000 OwnerUID=1000 GID=1000 EGID=1000 SGID=1000 FSGID=1000 SupplementaryGIDs=90 982 985 987 990 994 995 996 998 999 1000 Comm=systemd CommandLine=/usr/lib/systemd/systemd --user CGroup=/user.slice/user-1000.slice/user@1000.service/init.scope Unit=user@1000.service Slice=user-1000.slice UserUnit=init.scope UserSlice=-.slice Session=n/a AuditLoginUID=1000 AuditSessionID=3 EffectiveCapabilities=cap_wake_alarm PermittedCapabilities=cap_wake_alarm InheritableCapabilities=cap_wake_alarm BoundingCapabilities=cap_chown cap_dac_override cap_dac_read_search cap_fowner cap_fsetid cap_kill cap_setgid cap_setuid cap_setpcap cap_linux_immutable cap_net_bind_service cap_net_broadcast cap_net_admin cap_net_raw cap_ipc_lock cap_ipc_owner cap_sys_module cap_sys_rawio cap_sys_chroot cap_sys_ptrace cap_sys_pacct cap_sys_admin cap_sys_boot cap_sys_nice cap_sys_resource cap_sys_time cap_sys_tty_config cap_mknod cap_lease cap_audit_write cap_audit_control cap_setfcap cap_mac_override cap_mac_admin cap_syslog cap_wake_alarm cap_block_suspend cap_audit_read cap_perfmon cap_bpf cap_checkpoint_restore
Maybe one more thing I could mention is, that I have 3 different desktop-portals:
xdg-desktop-portal-gnome
xdg-desktop-portal-gtk
xdg-desktop-portal-hyprland
But I think that should not be an issue.

Re: Steam dumps core on first startup
hmm, dbus is good...
u said steam runtime is failing cuz of missing runtime so u could just install it from pacman
sudo pacman -S steam-native-runtimenow try with steam native runtime, if it works the steam install is broken
STEAM_RUNTIME=0 steammultiple portals is usually fine, but waylands kinda homeless, so check which one's active (should be ur de/wm; if you ARE on wayland i still recommend running on x11). if u feel like portals are the problem then u could just pacman -Rns the unused ones.
lets try gpu, try disabling gpu compositing
steam --disable-gpu --disable-gpu-compositingtheres one thing that could provide a lotta inspo (run this right after a failed steam launch)
journalctl --user -xe | grep -i dbusdouble launching means that it needs time to init or smth - i dont really know about that im not a steam expert, but tryna help the people best i can

Re: Steam dumps core on first startup
Thanks for the input, appreciate it!
Unfortunately, steam-native-runtime is not in the official repo, but only available via AUR.
Since the dependencies that come with it, are too complicated for me to fully understand, I would like to avoid installing it 
.
using
steam --disable-gpu --disable-gpu-compositingdoes not fix the issue.
the output of
journalctl --user -xe | grep -i dbusis:
...
