 @ayatsfer:matrix.org | so I've been playing with the KCL, and I do get a flicker-free boot from cold start into plymouth, but I'm missing the fade from plymouth into gnome-shell with autologin | 16:34:33 |
| @ayatsfer:matrix.org | I can try without autologin though | 16:34:40 |
 emily | FWIW, I believe Intel drivers are the furthest ahead for this, but K900 will know more up-to-date info than me. | 16:34:44 |
| emily | my guess is that the flicker is when it switches from the EFI FB driver to amdgpu, but I could be totally off here | 16:35:33 |
| @ayatsfer:matrix.org | without autologin (no gdm skip) seems to do the same: plymouth -> spinner stops -> black screen -> gdm | 16:37:25 |
 K900 | ^ | 16:37:37 |
| @ayatsfer:matrix.org | How many displays: 1, which exact AMD: ryzen 7 7840U, which kernel version?: 6.13.4
| 16:39:20 |
| K900 | Try boot.initrd.kernelModules = [ "amdgpu" ] | 16:39:53 |
| @ayatsfer:matrix.org | now I get no spinner and a black screen into GDM, lol | 16:42:53 |
| K900 | Then it's very likely your firmware is not setting the display to the correct mode | 16:43:57 |
| @ayatsfer:matrix.org | no idea then | 16:54:07 |
| K900 | In general any sort of flicker free anything requires the early boot firmware to cooperate | 16:54:31 |
| K900 | And in general not all firmware actually does | 16:54:37 |
| K900 | This is especially often the case with high refresh rate displays | 16:55:04 |
| K900 | Because it's common for the firmware to drive them at 60Hz anyway | 16:55:14 |
