This issue may be due to using bleeding edge mesa.

@gdrewb-valve sure, here are they: https://gist.github.com/maximvl/8405575, turning beta updates on does not help too, logs of beta steam: https://gist.github.com/maximvl/8405649. Im not able to switch to overlay at all.

@Tele42 xorg-edgers are used, Driver Version: 3.0 Mesa 10.1.0-devel is current driver.

Using Mesa 10.1 from Xorg-Edgers on Ubuntu 14.04, Steam Overlay fails aswell.

System:

Latest steam and xord-edgers updates fixed this, probably drivers cause the problem. Anyway it works now, should I close issue?

Problem fixed with latest updates.

I can reproduce this on Ubuntu 14.04 pre-beta with latest Steam.

Yep, issue present again. Ubuntu 14.04 with Oibaf PPA.

Same problem here, overlay does not work in any game I try. Ubuntu 14.04 with Mesa 10.1~rc1 from the main repo. Latest Steam Beta client.

Potentially interesting tidbit from the console output:

ERROR: ld.so: object '/home/alexandre/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
ERROR: ld.so: object '/home/alexandre/.local/share/Steam/ubuntu12_64/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

Same thing on up-to-date fedora rawhide with nodebug kernel. Dota2 and Portal2. The store payment is then not working anymore in Dota2.
https://gist.github.com/sylware/9337087

If I disable, in the properties, the steam overlay, Portal2 won't start and Dota2 does report the following error:
SDL_GL_LoadLibrary(NULL) failed: Failed loading libGL.so.1: /lib/libxcb-dri3.so.0: undefined symbol: xcb_send_fd

Same thing on mesa 10.1rc3 with alexmonthy's error. All games affected.

Delete
~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libxcb.so.1

Try again.

@ml-
Worked like a charm. Overlay back in dota2 and portal2. Thx!

@ml- Many internets to you, worked perfectly. Wonder what brought that on.

Such fix, wow, many thanks :)

Perfect

@ml- THANKS A LOT!!! Link delete, overlay running again.

Thank you verry much i had this problem for like a week and now i can finally accsess the tf2 store again!
Thank YOU!

Same problem here.

@ml- rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libxcb.so.1 doesn't happen for me.

I'm using Ubuntu 14.04 64 bits with nvidia-331-updates.

My custom launch options are LD_PRELOAD="libpthread.so.0 libGL.so.1" __GL_THREADED_OPTIMIZATIONS=1 $OPTIMUS_PREFIX %command% and the error I got is:

ERROR: ld.so: object '/home/ayrton/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

Same problem here with Civ 5:

ERROR: ld.so: object '~/Steam/ubuntu12_64/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded: ignored.

Ubuntu 12.04, 32 bits.

Well, I solved my problem removing all bumblebee stuff and installing nvidia-prime.
Doing this I also removed the launchd options. Now everything is working with my nvidia video card. And also, the performance is awesome.

Hy this Problem still exists, with civilisation 5.

@ml- rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libxcb.so.1 doesn't fix these for me, now i cant start steam.

Got thes error "Fatal ERROR: Failed to load Steamui.so"

FYI, the archlinux steam page had a fix that worked for me (https://wiki.archlinux.org/index.php/Steam#Steam_runtime_issues):

find ~/.steam/root/ \( -name "libgcc_s.so*" -o -name "libstdc++.so*" -o -name "libxcb.so*" \) -print -delete

This still doesn't work for me. Civ 5 crashes after starting a game from main menu. Running Ubuntu trusty on new Chromebook Pixel.

I had the same problem with Counter strike on Fedora. Disabling SELinux, it worked

Don't even have SElinux compiled in... something else, maybe the keyboard.

Here it is again, this time while trying to start Insurgency:

Using Steam on Debian with libgl1-mesa-dri:i386 and libgl1-mesa-glx:i386 installed (Using an AMD A10-5800K) and using a script to remove:
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1

rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libxcb.so.1

Forcing Steam to run on the systems libraries which works well for Counter-Strike_Source.

EDIT: Disabling the Steam Overlay doesn't do the trick.

Having this same issue right now.

I'm using Debian Stable with some backports pacakges (mainly nvidia-driver, xserver-xorg-video-intel, bumblebee-nvidia and primus).

But it happens only when trying to run dota 2 with primusrun or optirun (-b primus)

EDIT: Fixed using a downgraded version of libdrm (https://github.com/ValveSoftware/steam-for-linux/issues/3506)

Same issue with ubuntu 16.04 trying to launch home gone home (fglx)

Removing ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libxcb.so.1 did not work. Can't buy MvM tickets in TF2. Why do I have to use that crappy overlay to buy? Idiotic design.

It's related to the c++ ABI nightmare and some gcc BIP. valve SDK2 should
include static libstdc++ and static libgcc.
(c++ is already idiotic in itself...)

I am also getting this error, the script below used to fix this before upgrading to Ubuntu 16.10.

is telling you that preloading that library failed because it is 64 bit, while steam is 32 bit, so I was ignored. You could try preloading both the 32 bit and 64 bit variant.

@Tele42 , I have tried with 32-bit lib as well.
