 Posted: Tue Mar 25, 2025 8:17 pm Post subject: [SOLVED] Steamwebhelper crashes on startup |
 |
|
Hi all, after a couple of days of messing, I've reached the limits of my knowledge with steam. This is a brand new install, as vanilla as possible (so that I could maximise the use of binpkgs and get up and running in an afternoon). I'm using KDE Plasma/Wayland with nvidia-drivers (closed source), OpenRC, and current stable distkernel, unmodified. The profile is default/linux/amd64/23.0/desktop/plasma (stable). / and /home are on separate xfs partitions. At the end I've linked pastebin output for everything I can think of that might be useful.
Setup and prep:
This bit's also a bit of an aide-memoir for me for next time.
1) Built Gentoo following the handbook
2) Remembered to add nvidia_drm.modeset=1 and nvidia_drm.fbdev=1 to the kernel command line, otherwise Wayland failed in all sorts of creative ways (this really needs to be added to the wiki).
3) Built the 32bit libraries recommended in the wiki, as well as steam launcher from the overlay.
4) Amended fstab to allow exec and suid on /home (ref 7.2
-- The error "Couldn't set up steam data - please contact support" was caused by this.
Steam:
5) Tried to run steam - after about 10 seconds, a dialogue pops up notifying me that steamwebhelper has crashed. None of the alternative actions improve the situation.
6) ERROR: MESA-LOADER: failed to open dri: /usr/lib64/gbm/dri_gbm.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/gbm, suffix _gbm)
-- the file existed
-- re--emerged libdrm, mesa, llvm - no impact
-- emerge -aDU --with-bdeps=y @world - this pulled in more 32 bit libraries, but resolved the error.
7) Warning: GLib-GIO-WARNING **: 18:05:04.379: Can't find module 'dconf' specified in GSETTINGS_BACKEND
-- however, dconf has been merged. I don't know how to resolve this warning.
8) Despite all this, steamwebhelper crashes every single time with:
| Code: | Steam Runtime Launch Service: steam-runtime-launcher-service is running pid 3615

9) I have tried starting with -no-cef-sandbox, -cef-disable-gpu-compositing, -cef-disable-gpu, -vgui based on various guides. The console output is identical. After 10 seconds, the same dialogue box pops up informing me that Steam will go no further.
10) I've also tried starting from within Plasma/X11 - same result.
11) Tried deleting /tmp/dumps (ref) to no avail.
12) Tried deleting the nvidia cache (will update with ref when I find it again).
dmesg, /var/log/messages, /var/log/syslog, /var/log/Xorg.0.log all do not have any output relating to steam
The selection of logs in .share/steam/logs all seem to indicate that Steam is healthy and working - the only meaningful output I get is the console snippet above.
In summary, I have all the necessary files, libraries, working drivers, and other 3D stuff works fine. Steam still fails to launch. What am I missing?

Just to eliminate nvidia-drivers completely, I enabled the laptop's hybrid graphics (AMDGPU - renoir). If I can figure out a couple of nuisances with suspend/resume and multiple display handling, I might leave it this way. Anyway...
Steam identified both GPUs and set the primary device to AMD, and still failed to launch. I'll keep fiddling, but any advice appreciated.

Still playing - this is definitely something within this Gentoo setup (so something I've done/not done/should be able to fix). On another partition I installed OpenSuSE Tumbleweed - they tried their best but $deity help any new Linux users if that's their first experience of it. Anyway, steam works fine on that platform... I just don't like it. Plus, solving a puzzle's half the fun.
Within this installation:
Upgrading Mesa (25.0.0, 25.0.1, 25.0.2) and downgrading Mesa both had no effect
Neither upgrading the nvidia-drivers, nor downgrading them to 550-series had any effect.
Using the kernel-open build had no effect.
Calling steam with -textclient no longer works, as apparently the textclient is no longer installed as part of the Steam package.
I've also installed via Flatpak. In all cases, the only console or logfile output anywhere that records an error is: | Code: | | src/steamUI/steamuisharedjscontroller.cpp (669) : Failed creating offscreen shared JS context |
Anyone have any ideas what to try next?

Hello Kaitain,
I had a similar issue several months ago. There is a known problem with steamwebhelper on linux and mac.
I resolved it via downgrading steam and prohibiting its updates. I don't have now at hand all the links that helped me, this one is definitely of them:
https://github.com/Whisky-App/Whisky/issues/1199#issuecomment-2460454741
(I launch steam with exactly these options)

Hi halcon,
Thank you for this - the linked thread didn't quite work but gave me the right things to search for, which led me to this post, key steps being:
1) Install steam from the overlay - let it fail to start.
2) Create a steam.cfg file with:
| Code: | printf 'BootStrapperInhibitAll=enable
BootStrapperForceSelfUpdate=disable
' > ~/.local/share/Steam/steam.cfg |
3) Install the July 2023 version of steam, which has both the old -vgui option and the new authentication system using: | Code: | | steam -forcesteamupdate -forcepackagedownload -overridepackageurl https://web.archive.org/web/20230702125953if_/media.steampowered.com/client -exitsteam |
4) Run steam with | Code: | | /usr/bin/steam -noverifyfiles -nobootstrapupdate -skipinitialbootstrap -norepairfiles -overridepackageurl -vgui |
and admire the streams of error messages in the console. After a moment, the Steam login window opens, I log in, and I can download games.
The final hiccup was that I had video, but no sound. Re-emerging pipewire with the pipewire-alsa use flag fixed that.
Thanks again - I'm as happy as a dog with two, er, tails!

Kaitain,
I am glad to be of help.
So, you want to become the Elden Lord, do you?
