У меня есть sddm. В процессе загрузки получаю чёрный экран.
https://wiki.gentoo.org/wiki/NVIDIA/Optimus#Before_starting_X Всё сделано по инструкции к sddm, но всё так же чёрный. Как мне понять, запускается ли скрипт? Руками выполняется и говорит, что «cant open display» (запускаю без иксов его, естественно дисплея нет).

Что я вообще делал:
- emerge x11-drivers/nvidia-drivers
- в make.conf добавил VIDEO_CARDS=«intel i965 iris nvidia»
- в ядро:
[*] Enable loadable module support --->
Processor type and features --->
[*] MTRR (Memory Type Range Register) support
Device Drivers --->
Graphics support --->
[*] VGA Arbitration
Device Drivers --->
Character devices --->
[*] IPMI top-level message handler
Bus options (PCI etc.) --->
[*] Mark VGA/VBE/EFI FB as generic system framebuffer
Device Drivers --->
Graphics support --->
Frame buffer Devices --->
[*] Simple framebuffer support
и проверил нет ли там ничего лишнего от nvidia nouveau
- echo nvidia > /etc/modules-load.d/video.conf
- сгенерировал конфиг nvidia-xconfig
- в сгенерированном xorg.conf в секции Section «Device» заменил Identifier «Device0» на Identifier «nvidia»
- для sddm
