RECENT ANNOUNCEMENTS

Latest steam client beta again further improves compatibility with Exherbo

16 September, 2023 - tgurr | 0 Comments

After moving from a nvidia to an amd gpu I hit the problem of steam not starting anymore having problems to load the 32bit mesa libraries which led to an initial report[github.com].

The latest steam beta client as of September 15th ships with the updated steam-runtime-heavy 0.20230905.59208 and steam-runtime scout 0.20230905.59207 carrying the following fixes mentioned in the heavy release notes[gitlab.steamos.cloud] & scout release notes[gitlab.steamos.cloud] :

LD_LIBRARY_PATH runtime: Detect OS library directories from both word-sizes' versions of ldconfig on Exherbo, fixing Steam startup on that distribution (steam-runtime#615)
run.sh: Ask s-r-identify-library-abi for ldconfig's search paths, git commit[github.com]

It also ships with the updated steam-runtime-tools v0.20230905.0
carrying the supporting work needed, from the release notes[gitlab.steamos.cloud]:

identify-library-abi: On Exherbo, run both versions of ldconfig.
Unlike other multiarch/multilib designs, Exherbo has one build of
ldconfig per architecture, each with its own configuration that only
searches libraries intended for that word size.
(Helps: steam-runtime#615), git commit[gitlab.steamos.cloud]

This also led to another bug being discovered that the check-va-api of steam-runtime segfaulted on Exherbo so there wasn't any hardware acceleration available for e.g. streaming via Steam Link. This problem got reported to the mesa bugtracker[gitlab.freedesktop.org] and turned out get fixes on both ends:

Exherbo: Our mesa package was compiled with asserts enabled by default which was fixed, git commit[gitlab.exherbo.org].
steam-runtime: A bug in the check-va-api got fixed, git commit[gitlab.steamos.cloud].

As always it is astonishing how much Valve and especially the awesome individuals working on the steam-runtime at Collabora for Valve are dedicated in also supporting such a rather niche distribution like Exherbo, although the work done might also benefit other distributions of course. It's a real pleasure to work with them, report bugs and immediately get some responses which usually turn out to have things fixed for everyone to enjoy. Personal thanks again go to Simon McVittie (smcv) having done the actual work here - you're awesome!

An initial report[github.com] about vulkan layers like vkBasalt not working within recent Proton versions making use of the steam-runtime lead not only to having it fixed but also to various other improvements for compatibility with Exherbo Linux.

The latest steam-runtime beta versions >=0.20210317.0 carry the following fixes mentioned in the release notes release notes[gitlab.steamos.cloud]:

Compare libstdc++.so.6 by version definitions, so that we get the right version on e.g. Exherbo (steam-runtime#381[github.com])
Fix Proton setup commands in locales that use a decimal comma, such as de_DE (helps: steam-runtime#381[github.com])
Improve setup of locales, drirc.d and libdrm data on non-FHS systems such as Exherbo (related to steam-runtime#381[github.com])

Again thanks to the awesome people working on the steam-runtime at Collabora for Valve, in person the two people who did the actual work, Simon McVittie (smcv) and Ludovico de Nittis (denittis).

If you're interested in details, please see the following list of relevant commits to the steam-runtime and the steam-runtime-tools:

ABI: Compare libstdc++.so.6 by version definitions[gitlab.steamos.cloud]
rules: Add Exherbo locale symlinks[gitlab.steamos.cloud]
pv-wrap: Communicate timeouts to pv-adverb as locale-independent ASCII[gitlab.steamos.cloud]
runtime: Use "/usr/share" as a fallback lib data directory[gitlab.steamos.cloud]
runtime: Try Exherbo's locale dirs as a fallback[gitlab.steamos.cloud]

Additional notes

Please note that our packaged system installed version of e.g. vkBasalt doesn't work out-of-the-box under steam-runtime as neither /etc nor /usr are mapped into the container, so to get things working you've to configure vkBasalt.conf in your home directory and additionally copy over the Shaders and Textures into your home directory as well and setup their paths in vkBasalt.conf if you make use of the reshade shaders. A smiliar approach might apply to MangoHud.
