 Posted: Wed Oct 23, 2024 8:25 pm Post subject: SDDM exits on launch and drops to shell |
 |
|
when launching, or re-starting display-manager through openRC, as well as launching SDDM via the console manually, the screen slightly brightens for a moment, and shows a cursor, before darkening again. it then flashes bright and dark a few times, before exiting to console
Xorg seems to be working fine, as startx does bring up 3 terminals as expected of default behavior
sddm.log
standout lines:
| Code: |
[20:04:43.649] (WW) DAEMON: Auth: sddm-helper exited with 4
[20:04:43.649] (II) DAEMON: Greeter stopped. SDDM::Auth::HELPER_DISPLAYSERVER_ERROR
|
after this, it falls back from x11 to x11-user launch, resulting in this:
| Code: |
[20:04:44.214] (EE) HELPER: Failed to take control of "/dev/tty1" ("root"): Operation not permitted
[20:04:44.215] (II) DAEMON: Greeter session started successfully
[20:04:44.215] (II) HELPER: [PAM] Closing session
[20:04:44.215] (II) HELPER: [PAM] Ended.
[20:04:44.216] (WW) DAEMON: Auth: sddm-helper exited with 5
[20:04:44.216] (II) DAEMON: Greeter stopped. SDDM::Auth::HELPER_TTY_ERROR
|
Xorg.0.log
Xorg.0.log.old
(one attempted launch generated both)
things tried:
adding sddm user to tty group - no result
downgrading sddm to previous release - no result
this is an LLVM system.
if more information or additional test would help, please let me know hat else to do/share.
any help is appreciated

Is /etc/init.d/dbus running? < It's a dependency of sddm, but not picked up by display-manager when "sddm" is set in conf.d/display-manager. |

dbus is running, at least once the system is at the login shell (pretty sure NetworkManager is starting it, however there is no difference in sddm behavior between booting and running it from the shell (at which point dbus is definitely running) , so i don't think that's it.
whilst i was chrooted from an installation CD just now, i decided to try launching SDDM from the chroot shell, and got a different result (i didn't expect it to work, but thought it might reveal something). i saw a brief flash of the SDDM screen, then the system froze. |

| I don't think it'll be this, but I'm getting vague recollections of similar sddm.log entries when support for my ancient gpu was dropped from mesa: Run startx as root, and make sure glxgears works, just to disprove it's a similar issue. |
