`ui/frame_backup.py session` reported Desktop Mode despite gamescope, and

`ui/frame_backup.py game-mode` invoked the same guarded Return function used by

the button. Game Mode became active and a second call made no switch. Battery

Later on 2026-10-24, the published **v0.4.17 Linux x86_64 AppImage** passed the

literal packaged-button check on the same Frame/build. With the shared lock and

a verified three-minute rollback timer, the headset entered full Plasma Desktop

the visible **Return to Game Mode** button, accepting its confirmation, returned

confirmed Game Mode. A second confirmed button click returned `switched: false`;

the Game Mode service invocation and SteamVR PID stayed unchanged. **Check**

then reported Game Mode and disabled Return. The test app/server and virtual

# Linux PC host feasibility on lxso2, 2026-10-24
|
||||
|
||||
**Blocked on this host's current desktop environment. No feature enabled and
|
||||
no feature PR opened.** Investigation for [issue #23](https://github.com/saphid/frame-control/issues/23),
|
||||
starting at `4e45648` (main after #154). This concerns flat desktop panels,
|
||||
not Linux PC VR streaming.
|
||||
|
||||
## Decision
|
||||
|
||||
The smallest useful candidate is one explicitly selected **whole screen**,
|
||||
captured through the ScreenCast portal's restricted PipeWire connection,
|
||||
encoded locally with GStreamer/x264, and sent to the existing viewer through
|
||||
the shared SSH controller. Input, individual windows and virtual displays
|
||||
would remain unsupported until separately verified. This candidate was **not
|
||||
implemented**: lxso2 currently cannot exercise the real capture permission path.
|
||||
|
||||
Development packages could unblock compilation, but would not create a desktop,
|
||||
portal backend or consented screen. Synthetic encoding, an Xvfb screen grab or
|
||||
using the Frame as its own host would not verify Linux PC desktop capture.
|
||||
No host packages or services were changed.
|
||||
|
||||
## Evidence
|
||||
|
||||
Host: `lxso2`, Linux x86-64, kernel `6.8.0-139-generic`.
|
||||
|
||||
- `DISPLAY`, `WAYLAND_DISPLAY` and `XDG_SESSION_TYPE` were unset. The user bus
|
||||
was reachable at `/run/user/1000/bus`.
|
||||
- `/run/user/1000/pipewire-0` and `/run/user/1000/wayland-0` did not exist.
|
||||
No processes matched Xorg, Xwayland, Xvfb, GNOME Shell, KWin Wayland, Weston,
|
||||
PipeWire, WirePlumber or xdg-desktop-portal at the process check.
|
||||
- D-Bus `ListNames` returned D-Bus, systemd and anonymous connections, with no
|
||||
`org.freedesktop.portal.Desktop`. `ListActivatableNames` also had no desktop
|
||||
portal. These calls queried D-Bus itself without activating capture services.
|
||||
- `dpkg-query` found no `xdg-desktop-portal*` or `pipewire*` packages.
|
||||
`libgstreamer1.0-0:amd64` was installed at `1.24.2-1ubuntu0.1`, but
|
||||
`gstreamer1.0-tools` was uninstalled. `gst-launch-1.0` and `gst-inspect-1.0`
|
||||
were absent from PATH. Xvfb was installed, but supplies no portal by itself.
|
||||
- `pkg-config --modversion` failed for `gstreamer-1.0`,
|
||||
`gstreamer-app-1.0`, `gstreamer-video-1.0` and `libpipewire-0.3`.
|
||||
`gio-unix-2.0` reported `2.80.0`.
|
||||
- `desktop/bundle/pc-host.so` did not exist.
|
||||
`python3 desktop/build.py --with-x264 --out /tmp/frame-linux-pc-feasibility`
|
||||
exited **1** before compilation: required GStreamer pkg-config modules were
|
||||
missing. No native build or encoder runtime success is claimed.
|
||||
|
||||
Reproduce the non-activating portal checks in the intended desktop user's
|
||||
session, using that session's actual runtime directory and bus:
|
||||
|
||||
```sh
|
||||
gdbus call --session --dest org.freedesktop.DBus \
|
||||
--object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListNames
|
||||
gdbus call --session --dest org.freedesktop.DBus \
|
||||
--object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListActivatableNames
|
||||
pkg-config --modversion gstreamer-1.0 gstreamer-app-1.0 gstreamer-video-1.0 gio-unix-2.0
|
||||
```
|
||||
|
||||
## Existing implementation reviewed
|
||||
|
||||
- `ui/frame_pcview.py` selects PCView only on Windows and rejects Linux even
|
||||
when enabled. Linux installers do not carry its native bundle.
|
||||
- `desktop/portal.c` creates a **RemoteDesktop** session, requests pointer and
|
||||
keyboard devices, and selects monitors and windows (`types=3`). It is not
|
||||
ScreenCast-only or screen-only. Its restricted fd/node and fresh-connection
|
||||
handling are reusable.
|
||||
- `ui/frame_pc_agent.py` calls the selection a shared window or screen and
|
||||
picks VA-API when the element is present, falling back to x264. A bounded
|
||||
x264 slice needs explicit encoder policy and unsupported-input behavior;
|
||||
exposing the existing Linux path alone would not meet that scope.
|
||||
- `app/main.js` starts Python with the inherited environment; it does not
|
||||
supply a compositor, portal backend or capture permission.
|
||||
- `.github/workflows/pc-host.yml` installs native dependencies and tests
|
||||
synthetic x264/protocol behavior with fake capture consent/input. This does
|
||||
not establish interactive Linux desktop capture.
|
||||
- Issue #23 and its six existing comments distinguish prior synthetic
|
||||
helper/viewer results from untested Linux desktop capture and consent.
|
||||
|
||||
## Verification and limits
|
||||
|
||||
`python3 -m unittest discover -s tests -p 'test_pc*.py' -v` exited **0**:
|
||||
27 tests ran successfully, with one additional native-class setup skip
|
||||
(`native PC libraries not built on this host`). Coverage includes the compiled
|
||||
C controller trace, Python adapters, grants and default-off/Windows-only gates.
|
||||
It does not prove native GStreamer capture or local-client streaming.
|
||||
|
||||
No fake/local native stream, consent prompt, real desktop capture, Frame viewer
|
||||
run, benchmark, input or window mode was tested in this investigation. No SSH
|
||||
connection to the Frame was needed; no lock was acquired and no headset install,
|
||||
launch, stop or settings change was attempted. Issue #113 was left alone.
|
||||
No issue comments or other public messages were sent.
|
||||
|
||||
## Concrete unblock and next slice
|
||||
|
||||
1. Supply an interactive Linux desktop, physical or VM, with a working
|
||||
ScreenCast portal/backend, PipeWire and accessible consent dialog. Installing
|
||||
the portal frontend alone is insufficient. A VM can establish software
|
||||
capture/x264 behavior while physical-host behavior remains unverified.
|
||||
2. Install the native dependencies listed in `pc-host.yml` in that environment
|
||||
and build a local `--with-x264` bundle. Resolve x264 distribution
|
||||
licensing/source obligations before shipping it: the current build labels
|
||||
that option test-only and the Windows installer omits it.
|
||||
3. Implement a ScreenCast-only session with monitor-only selection, no
|
||||
RemoteDesktop/device request, disabled input in protocol and viewer, hidden
|
||||
window/virtual-display modes, and explicit x264 selection. Preserve the
|
||||
default-off gate and existing Mac/Windows paths.
|
||||
4. Verify consent acceptance/refusal/cancellation, Stop/reopen, connection loss
|
||||
and portal closure with a local client decoding actual captured content.
|
||||
Run the shared benchmark and record results without inferring hardware or
|
||||
physical laser behavior.
|
||||
5. Only after local capture works, acquire the shared Frame lock once and
|
||||
follow [the headset procedure](../testing.md#headset-smoke-test) for a brief
|
||||
viewer test. If occupied, leave the lock alone and defer device testing.
|
||||
|
||||
These are prerequisites and proposed scope, not a ready feature. The Linux
|
||||
host request in #23 remains open.
