Can't bring up overlay since the Jan 19 update

Your system information

• Steam client version: 1484790260
• Distribution (e.g. Ubuntu): Ubuntu 16.04, 64 bit
• Opted into Steam client beta?: [Yes/No] No
• Have you checked for system updates?: [Yes/No] Yes

Please describe your issue in as much detail as possible:

Describe what you expected should happen and what did happen. Please link any large code pastes as a Github Gist

When pressing Shift+Tab in game I expect to see Steam overlay and FPS counter. This was working fine before latest client update released on January 19th.

Steps for reproducing this issue:

1. Install Steam from apt on an up-to-date Ubuntu 16.04 64-bit system using nvidia-378 proprietary drivers
2. Make sure Steam -> Settings -> In-Game indicates that in-game overlay is enabled
3. Start any game (e.g., Counter-Strike: Global Offensive) and attempt to bring up the overlay using shortcut keys

Hello @radical-equanimity, after running a game with the overlay, please copy the stdout log from either /tmp/dumps/<username>_stdout.txt or completely close steam, then run steam from a terminal and put it in a gist.

Does the overlay have a problem if you run steam from a terminal with STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 steam?

[lowlyocean]

The overlay is still not accessible if I run with STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 steam.

@kisak-valve Something has gone wrong with the update and Steam wasn't able to find correct libs after. @radical-equanimity was able to make Steam start but some libs might be still missing in action. FYI http://steamcommunity.com/app/221410/discussions/0/143388344304227393/

@triage-valve @kisak-valve I have some more information. At the moment I launch CS:GO, I notice that .steam/error.log reports the following error: ERROR: ld.so: object '/home/daniel/.steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored

Tried preloading the 64-bit version; the message in error.log goes away but I still can't bring up overlay or see my FPS. LD_PRELOAD='~/.steam/ubuntu12_64/gameoverlayrenderer.so' steam

Has something recently changed with the way the overlay libraries are loaded on a 64-bit Linux machine?

[kisak-valve]

Steam preloads both the 32 bit variant and 64 bit variant of the overlay when starting a steam game. One works while the other harmlessly fails. This is not an indicator of a problem.

I understand, thank you. I've removed the .steam directory and installed the latest .deb from steampowered.com. After installing, I launched CS:GO. I've attached the output of "lsof -p | grep .so" for the pids of the steam client as well as the Counter-Strike executable. The output of this command shows the shared libraries that are being accessed by each of those running processes, including their paths on the filesystem. Do you notice any combination of libraries that would cause the overlay to fail? Please let me know what else is needed- some game functionality relies on overlay to be working.

@kisak-valve This is odd- I ran a trace on gameoverlayui and it references something called WinAppMain. Has the Linux overlay been built using Windows source code in latest update, explaining the segfault below?

daniel@daniel-desktop:~$ ltrace -f  /home/daniel/.local/share/Steam/ubuntu12_32/gameoverlayui

Edit: If I add $HOME/.local/share/Steam/ubuntu12_32 to /etc/ld.so.conf.d/steam.conf and run ldconfig, I get different output and seems to execute normally. However, I don't see the same output when launching CS:GO

[lowlyocean]

Are these versions of the system C/C++ components (latest from Ubuntu 16.04) compatible with Steam?

The overlay works for Rocket League, but not for Counter-Strike: Global Offensive

Hello @lowlyocean, are you still experiencing this issue on an up to date system?

[kisak-valve]

Closing pending feedback.
