https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D290471 --- Comment #15 from Tomoaki AOKI <junchoon@dec.sakura.ne.jp> --- Tried stupid test for x11-wm/niri on: stable/15, amd64 at commit c412af68cb60f54fdbc29eb09e35869ed07c93f7 x11/nvidia-kmod-devel + x11/nvidia-driver-devel + graphics/drm-66-kmod + graphics/nvidia-drm-66-kmod-devel, with main branch of ports tree at commit c9c996ad6b8fb4a3cde65a0b1c517941dc4f77c7 niri failed to start, but kernel didn't panic. And backtrace looks alike the one in Comment 11. No workaround shown upstream are NOT applied (thus, stupid test). Existence of DRI devices (after restart of test, but the same except date/time): % ls -l /dev/dri total 0 lrwxr-xr-x 1 root wheel 8 10=E6=9C=88 29 18:41 card0 -> ../drm/0 lrwxr-xr-x 1 root wheel 10 10=E6=9C=88 29 18:41 renderD128 -> ../drm/128 % ls -l /dev/drm/0 crw-rw---- 1 root video 0xeb 10=E6=9C=88 29 18:41 /dev/drm/0 % ls -l /dev/drm/128 crw-rw---- 1 root video 0x16b 10=E6=9C=88 29 18:41 /dev/drm/128 %=20 Error messages on screen: % niri --session 2025-10-29T00:36:52.665048Z INFO niri: starting version 25.08 (unknown com= mit) 2025-10-29T00:36:52.686433Z DEBUG niri_config: loaded config from "/home/********/.config/niri/config.kdl" Oct 29 09:36:52 ******** seatd[4799]: 00:04:43.724 [INFO] [seatd/server.c:1= 46] New client connected (pid: 8068, uid: 1001, gid:0) 00:04:43.724 [INFO] [seatd/seat.c:239] Added client 1 to seat0 Oct 29 09:36:52 ******** seatd[4799]: 00:04:43.724 [INFO] [seatd/seat.c:563] Opened client 1 on seat0libinput error: event11 - Wacom Pen and multitouch sensor Finger: libinput bug: kernel fuzz of 4 but LIBINPUT_FUZZ_35 is missi= ng libinput error: event11 - Wacom Pen and multitouch sensor Finger: libinput bug: kernel fuzz of 4 but LIBINPUT_FUZZ_36 is missing thread 'main' panicked at src/main.rs:176:6: called `Result::unwrap()` on an `Err` value: error initializing the TTY backend Caused by: 0: error opening the primary GPU DRM node 1: the provided file descriptor does not refer to a DRM node stack backtrace: 0: __rustc::rust_begin_unwind 1: core::panicking::panic_fmt 2: core::result::unwrap_failed 3: niri Related outputs in /var/log/messages: Oct 29 09:36:52 ******** seatd[4799]: 00:04:43.724 [INFO] [seatd/server.c:1= 46] New client connected (pid: 8068, uid: 1001, gid: 0) 00:04:43.724 [INFO] [seatd/seat.c:239] Added client 1 to seat0 Oct 29 09:36:52 ******** seatd[4799]: 00:04:43.724 [INFO] [seatd/seat.c:563] Opened client 1 on seat0 Oct 29 09:36:53 ******** devd[4397]: check_clients: dropping disconnected client Oct 29 09:36:53 ******** seatd[4799]: 00:04:44.342 [INFO] [seatd/client.c:4= 96] Client disconnected Oct 29 09:36:53 ******** seatd[4799]: 00:04:44.363 [INFO] [seatd/seat.c:158= ] No clients on seat0 to activate 00:04:44.363 [INFO] [seatd/seat.c:290] Removed client 1 from seat0 Oct 29 09:36:53 ******** kernel: pid 8068 (niri), jid 0, uid 1001: exited on signal 6 (core dumped) Oct 29 09:37:53 ******** devd[4397]: check_clients: dropping disconnected client Oct 29 09:37:53 ******** syslogd: last message repeated 2 times Oct 29 09:38:45 ******** seatd[4799]: 00:06:36.927 [INFO] [seatd/server.c:1= 46] New client connected (pid: 8077, uid: 10002, gid: 5) Oct 29 09:38:45 ******** seatd[4799]: 00:06:36.927 [INFO] [seatd/seat.c:239] Added client 1 to seat0 Oct 29 09:38:45 ******** seatd[4799]: 00:06:36.927 [INFO] [seatd/seat.c:563] Opened client 1 on seat0 Oct 29 09:38:46 ******** seatd[4799]: 00:06:37.361 [INFO] [seatd/client.c:4= 96] Client disconnected Oct 29 09:38:46 ******** seatd[4799]: 00:06:37.363 [INFO] [seatd/seat.c:158= ] No clients on seat0 to activate 00:06:37.363 [INFO] [seatd/seat.c:290] Removed client 1 from seat0 Oct 29 09:38:46 ******** kernel: pid 8077 (niri), jid 0, uid 10002: exited = on signal 6 (core dumped) Oct 29 09:39:38 ******** devd[4397]: notify_clients: send() failed; dropping unresponsive client Backtrace: % lldb --core /var/tmp/niri.core --file /usr/local/bin/niri=20=20=20 (lldb) target create "/usr/local/bin/niri" --core "/var/tmp/niri.core" Core file '/var/tmp/niri.core' (x86_64) was loaded.
