Same error on 6.4 stable :/ | 13:04:20 |
 K900 | Same versions of everything else? | 13:05:35 |
| K900 | Could be some weird kernel/mesa/libdrm/whatever regression | 13:05:44 |
| Marie | In reply to @k900:0upti.me
Same versions of everything else? should be yes | 13:06:17 |
| K900 | Hmm | 13:08:25 |
| K900 | Do you have a full line of that? | 13:08:35 |
| Marie | of the coredump? | 13:08:54 |
| K900 | Oh wait that is the full line | 13:10:21 |
| K900 | Ugh | 13:10:23 |
| K900 | I wonder if it's just a missing QML component again | 13:10:31 |
| K900 | Can you try running sddm-greeter --test-mode in a clean environment | 13:11:05 |
| Marie | clean environment means what exactly? | 13:15:19 |
| Marie | and i assume you mean sddm-greeter-qt6? | 13:15:51 |
| K900 | Yes | 13:19:01 |
| K900 | Clean environment means no existing environment variables | 13:19:09 |
| K900 | Like env -i sddm-greeter-qt6 --test-mode | 13:19:24 |

| Marie | wait which part of this is supposed to create the wayland socket? | 13:22:55 |
| K900 | It's not | 13:25:28 |
| K900 | You want to run it in an existing compositor | 13:25:33 |
| Marie | okay so i started plasma manually and sddm-greeter-qt6 also starts with that command | 13:29:38 |
| Marie | but with the default theme, not sure if it's supposed to do that (?) | 13:30:18 |
| K900 | Yeah it's not | 13:40:08 |
| K900 | It should log an error | 13:40:11 |
| K900 | About what it can't find in the Breeze theme | 13:40:16 |
