 aktaboot | and different cable doesnt change much | 06:23:06 |
 K900 (Old) | Yeah that makes sense if it's a dock and also DP | 06:23:14 |
| K900 (Old) | Is it a Thunderbolt/USB4 dock or USB3? | 06:23:27 |
| aktaboot | yeah it seems to always work | 06:23:34 |
| aktaboot | not entirely sure but Ig USB3 | 06:23:52 |
| aktaboot | never had the issue until very recently though | 06:24:06 |
| aktaboot | my setup didnt change | 06:24:18 |
| aktaboot | USB3.1! | 06:24:48 |

| K900 (Old) | That's not a very accurate way tbh | 06:25:58 |
| K900 (Old) | But I'm guessing it's not TB | 06:26:45 |
| K900 (Old) | Because there's like | 06:26:51 |
| aktaboot | yeah i'm pretty sure it's not | 06:26:55 |
| K900 (Old) | Five different flavors of DP-over-USB | 06:27:09 |
| K900 (Old) | And they're all weird | 06:27:21 |
| aktaboot | https://support.lenovo.com/us/en/solutions/acc500106 | 06:27:28 |
| aktaboot | so your guess is its very probably Dock-related and not kwin-related? | 06:28:08 |
| aktaboot | or not necessarily | 06:28:15 |
| K900 (Old) | It's either dock related or whatever specific flavor of DP-over-USB it's doing | 06:29:30 |
| K900 (Old) | But seeing the three display outputs on that dock | 06:29:37 |
| K900 (Old) | There's probably an MST splitter inside or something | 06:29:45 |
| K900 (Old) | This may sound stupid as all hell | 06:29:53 |
| K900 (Old) | But have you tried the other DP port | 06:29:59 |
| aktaboot | i think i did, lemme try again | 06:30:12 |
| aktaboot | yeah monitor wakes up and then sleeps | 06:31:08 |
| aktaboot | as it does with kscreen-doctor enable/disable | 06:31:40 |
| aktaboot | Ig that's also even if it works when i switch tty? | 06:33:10 |
| K900 (Old) | It's really weird tbh | 06:33:28 |
| aktaboot | sorry, english | 06:33:35 |
| K900 (Old) | It may be a kernel driver thing | 06:33:37 |
