When smithay's DrmDevice::activate() returns an error (e.g. because
drmSetMaster() failed during VT resume), resume_session() was only
logging the error and then proceeding to resume DRM leases on a device
that has no master. This leaves the compositor in a broken render state
where every atomic page flip returns EPERM.
Fix: continue to the next device on activate() failure. The device
surface stays inactive and lease resume is deferred. On the next
ActivateSession event (next VT switch to this TTY), resume_session()
will be called again and activate() will succeed once the seat manager
has granted DRM master.
Reproducer: hybrid GPU system (Intel iGPU render + NVIDIA display),
VT switch away from and back to COSMIC session. On return, drmSetMaster
races the seat notification; activate() fails; without this fix
the compositor floods journald with EPERM at 60fps.
Fixes: pop-os#2331, pop-os#2302
Adds a cursor_hide_timeout config key (Option<u32> seconds) to
CosmicCompConfig. When set, the cursor is hidden after the configured
period of pointer inactivity and revealed again by any pointer event.
Touch input does not count as activity (no visible cursor to surface).
Implementation:
- Per-seat hidden flag, calloop timer token, and last-armed Instant on
CursorStateInner.
- notify_cursor_activity called from each pointer-related input branch
(motion, button, axis, tablet) resets the flag and reschedules the
timer; rapid successive calls are coalesced behind a 100ms throttle
so high-frequency mice don't churn the calloop timer source.
- On timer fire, the hidden flag is set, draw_cursor short-circuits to
an empty element list, and a render is scheduled. Active pointer
grabs (drags, resizes) suppress the hide.
- Config reload arms or cancels the timer immediately; None as the
configured value collapses the cancel path into the same function.
Closes#2231.
Drafted with Claude (Anthropic); reviewed and tested by the committer.
Everything implementing `AsGlowRenderer` implements `Renderer` and various
other traits, and by making `AsGlowRenderer` depend on these trait,
things requiring `AsGlowRenderer` can avoid listing those traits as
well.
Looks like implied trait bounds still won't work for the
`Self::TexutureId` and `Self::Error` requirements? So those are not
included here.
