Chrome, Chromium, VSCode, Slack, Signal, Discord, element-desktop,
schildichat.
For the latter two, the feature flag useWayland was removed and a
wrapper script was provided.
NixOS stores ICDs at /run/opengl-driver/share/vulkan/icd.d/. Because
Chrome ships its own vulkan-loader and doesn't use the NixOS system
vulkan-loader, Chrome won't search the /run/opengl-driver directory
withou either adding it to the path or patching Chrome's libvulkan.so.1.
This change adds "${addOpenGLRunpath.driverLink}/share" unconditionally
to the path. addOpenGLRunpath is the same module that NixOS system
vulkan-loader uses as the path.
Tested by running `VK_LOADER_DEBUG=all google-chrome-unstable
--enable-features=Vulkan` and verifying Vulkan is enabled with
chrome://gpu.
If our Chrome derivation is Vulkan enabled, the Chrome GPU process
reliably crashes for me under M92 using the proprietary Nvidia drivers.
This is because the PCI-based GPU detection path fails, and we attempt
to use the Vulkan fallback instead, which then crashes(!!)
Including libpci allows us to use Angle's
src/gpu_info_util/SystemInfo_libpci.cpp path instead, which doesn't
crash, unlike src/gpu_info_util/SystemInfo_vulkan.cpp.
Chrome cannot do hardware video acceleration without libva in its search
path. This just adds libva. Tested against a VP9 video looking at
chrome://media-internals and intel_gpu_top.
This is required to launch newer versions of Google Chrome:
/nix/store/XXX-google-chrome-dev-89.0.4385.0/share/google/chrome-unstable/google-chrome-unstable:
error while loading shared libraries: libxshmfence.so.1: cannot open
shared object file: No such file or directory
update.nix was a huuuuge hack, abusing checksum collisions, etc., and
was extremely difficult to read and maintain, especially because
values from update.nix were also used in the derivations themselves!
I've replaced this with an implementation in Python, which I chose for
readability. Rather than generating Nix, I chose to
generate JSON, since Python can do that in the standard library and
Nix can read it.
I also set update.py as an updateScript, so Chromium can now
automatically be updated!
Fixes: https://github.com/NixOS/nixpkgs/issues/89635
See 3fadc45499. Since the beta channel is now also on 81 and the stable
channel will be on 81 soon, it makes sense to already add this
unconditionally for all channels.
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
diffpdf: fixup
This "with" usage makes it trickier to track where the actual source
package of this derivation comes from. Remove that use of with to make
it a little easier to understand.
