Steam client not launching

System information

Steam client version (build number or date): 1.0.0.54
Distribution (e.g. Ubuntu): Arch Linux
Opted into Steam client beta?: No
Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

The Steam client is not launching for the last week or so, despite my cleaning up of all previously installed artifacts. The output on the console looks pretty similar to the output in issue #4850. I have pasted mine below:

Setting LANG=C solved the problem in #4850, but that did not work for me.

Steps for reproducing this issue:

rm -rf ~/.steam ~/.local/share/Steam
LC_ALL=en_US.UTF-8 LANG=C steam-native

Hello @pnrao, since you are running steam-native, you should also bring this issue to the attention of your package maintainer for steam.

Possibly related to #4881.

I tested with the steam runtime also, but my results were pretty-much the same. Here's the output:

% rm -rf ~/.steam ~/.local/share/Steam
% LC_ALL=en_US.UTF-8 LANG=C steam

Same issue running Arch too BUT with WINE steam prefix.

It just crashes on this.

c0rn3j@c0rn3jDesktop  ~  WINEPREFIX=~/.wineSteam wine ~/.wineSteam/drive_c/Program\ Files\ (x86)/Steam/Steam.exe
err:winediag:xrandr12_init_modes Broken NVIDIA RandR detected, falling back to RandR 1.0. Please consider using the Nouveau driver instead. fixme:ver:GetCurrentPackageId (0x32e440 (nil)): stub ILocalize::AddFile() failed to load file "public/steambootstrapper_english.txt". fixme:process:ProcessIdToSessionId Unsupported for other processes.

EDIT: cd into the directory gets rid of the bolded error, I don't think it's related after all.. EDIT2: My issue was caused by other instance of Steam already running in the background, SIGTERMing it and relaunching steam worked, sorry for being irrelevant!

This could possibly be merged with #4815.

Same here, crashes since somewhen last week. I run Debian/Sid. I also deleted everything and got pretty much the same output as pnrao. I don't think this adds anything, but still, here it is:

Also tested with combinations of STEAM_RUNTIME and STEAM_RUNTIME_PREFER_HOST_LIBRARIES, same result.

And I don't have any idea what this aa_DJ locale does there, I think that's also a bug. my LC_CTYPE is en_GB.UTF-8, and my LC_COLLATE is de_CH.UTF-8.

Addendum: It gets even weirder when started with as "LC_ALL=en_GB.UTF-8 LANG=C steam":

Addendum 2: Turns out these are symlinks, so: /usr/lib/locale/en_GB.utf8/LC_CTYPE -> ../aa_DJ.utf8/LC_CTYPE

Here's the output of valgrind. Note that this is not using the steam-provided libraries. As far as I can see, I would say the error is a bad parameter for X_ChangeProperty

@Seegras, your issue sounds like #4417. Does LD_PRELOAD='/usr/$LIB/libstdc++.so.6' steam or simular allow steam to start on your system?

@kisak-valve This doesn't change anything. I also tried it without the whole runtime (all libraries from system) and it doesn't make much difference, it always crashes around the same place.

What I did now is to run the whole thing with the steam-runtime, and valgrind. I didn't expect it to throw the same error. But it did:

I now tried with different versions of steam, and different libraries, and I consistently get this crash. The whole steam runtime has no influence at all, as this crash happens before anything else gets loaded. So I set up steam on a notebook running Debian Scratch and the nouveau drivers, on which it did not crash.

I analysed the dependencies of the linked libraries of steam itself, those that differ are: (runs): libgcc1:i386 1:6.3.0-6, libstdc++6:i386 6.3.0-6 and respectively: (crashes): libgcc1:i386 1:6.3.0-9, libstdc++6:i386 6.3.0-9 All the other libraries are the same. So I tried with LD_PRELOAD='/home/user/preload/libgcc_s.so.1 /home/user/preload/libstdc++.so.6' /usr/lib/games/steam/steam with the 6.3.0-6-versions. Still crashes. And downgrading is neigh impossible, as around 50 packages, mostly libraries, depend on 6.3.0-9.

I'd say it's between steam and X11 now, respectively the nvidia-drivers (I run 375.27.13 because of SteamVR). The differences there: (runs): xserver-common 2:1.19.2-1, xserver-xorg-core 2:1.19.2-1, xserver-xorg-video-nouveau 1:1.0.13-2 and (crashes) xserver-common 2:1.19.3-1, xserver-xorg-core 2:1.19.3-1, xserver-xorg-video-nvidia 375.27.13-1

@Seegras Following the discussion at https://bbs.archlinux.org/viewtopic.php?pid=1688399, I completed the client installation with steam -textclient. After the steam client downloaded all its required files, I was able to run it with STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 steam.

@pnrao Indeed, this works. Of course the steam client crashes at every update and needs to be upgraded via steam -textclient every time.

What is with this issue? I am running Ubuntu 18.04 and Steam is broken here. Any work is going on? Thanks @pnrao for the workaround!
