[SOLVED] steamwebhelper not responding / launching, out of ideas

Hello! A few days ago, I momentarily downgraded my nvidia-open drivers to run some troubleshooting on an unrelated issue. I brought them back up to date soon after, but ran into a few hiccups along the way, which seem to have started this. Since then, Steam has been failing to launch with errors primarily pertaining to steamwebhelper. I've done all I could, but both my ideas and search results have run dry now, so I'm finally asking for help here.

To start, here's the stdout output of running 'steam':
It starts with a few warnings I couldn't find anything on, then, when steamwebhelper tries to start, it fails, tries again for a while, eventually opens a window identical to one shown below, and then keeps trying again until terminated.

steamwebhelperproblem.png

None of the options in this menu help, and I've followed all basic troubleshooting steps that I'm aware of, including a full system upgrade and reinstalling after purging all of its files.

I'm at a loss for what to do now, so if anyone can make anything out of this, even just a potential lead to follow, I would be immensely grateful. Please tell me if there are any more logs that could be of use, or any unusual troubleshooting steps to try. Thanks in advance!

Hybrid graphics?
Do you have the vulkan implementation for the IGP installed (incl the lib32 package)?

Yes, intel integrated + nvidia discrete. I did not have them before, but installing both vulkan-intel and lib32-vulkan-intel sadly didn't help.

Around the same time steam broke, pacman started giving me this odd segfault after any installation/removal, no actual visible effect on anything, but I figured it's worth mentioning:

...

vulkaninfo --summary might also be relevant here:

I've forgotten the precise details by now, but it definitely wasn't very clean. That is to say, it would indeed make sense if the issue was related to mesa/vulkan.

Re: [SOLVED] steamwebhelper not responding / launching, out of ideas

GPU0 is the nvidia one, using the nvidia-open driver, 

glxinfo -B

and please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General (steam in doubt uses xwayland) - what kind of session are you running?

Do you have a coredump for the segfault?
Try "pacman --debug" for context (if otherwise can't determine what actually crashes there)

Looks like it's ldconfig causing issues for pacman, just like with steam. It also segfaults when ran by itself. I haven't properly debugged anything in this way before, so I'm not really sure what I'm doing, so I'm not sure how I would share a coredump file, but here's a result of running 'gdb ldconfig <core file>' and seeing the backtrace.

Re: [SOLVED] steamwebhelper not responding / launching, out of ideas

Looks like /usr/lib32/libgallium-26.0.4-arch1.1.so is corrupted.

pacman -Qikk lib32-mesa

and probably also 

sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files' | grep -v backup

I'm running Wayland, so there are no X logs to share

What kind of "wayland"? You're certainly running the session on the nvidia GPU.

You're right, libgallium was corrupted. Moving away the file and reinstalling lib32-mesa fixed everything, pacman and steam work without a hitch now. Thank you!! The help was great, I feel like I actually learned something new too. Never would've delved into this by myself.

I'm running Hyprland, just switched over from i3 last week so I'm still unfamiliar with some aspects of Wayland, apologies. It seems Wayland compositors are a lot more independent from the server than X11 WMs, does that also mean there's no such thing as a "universal" Wayland log, and everything would be in the Hyprland logs?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

You should still check the overall integrity to make sure that not more files are compromised (nb. that some deviations are normal and harmless, notably in /etc - but nothing use /usr/lib and probably /usr/bin should be off)

Yes. Actually Hyprland (the wayland compositor) *is* the equivalent Xorg (ie. the display server implementation) next to also being the window manager (w/ the exception of https://archlinux.org/packages/extra/x86_64/river/ )
