Quando estou no kernel 3.8.13, posso mudar meu brilho usando xbacklight . Eu compilei 3.10.7-r1 usando genkernel all . Antes da atualização, recebi um aviso de "problemas compatíveis com os usuários do Nvdia" de emerge , mas ainda não sei os detalhes.
Existe mesmo assim para me deixar definir o brilho?
Então eu encontrei um ebuild app-laptop/nvdiabl-0.81 e tentei emerege nvidabl , eu recebi esta mensagem:
Your kernel does not support FB_BACKLIGHT. To enable you it you can enable any frame buffer with backlight control or nouveau. Note that you cannot use FB_NVIDIA with nvidia's proprietary driver Please check to make sure these options are set correctly. Failure to do so may cause unexpected problems. Once you have satisfied these options, please try merging this package again. ERROR: app-laptop/nvidiabl-0.81::gentoo failed (pretend phase): Incorrect kernel configuration options
Call stack: ebuild.sh, line 93: Called pkg_pretend nvidiabl-0.81.ebuild, line 31: Called linux-mod_pkg_setup linux-mod.eclass, line 559: Called linux-info_pkg_setup linux-info.eclass, line 911: Called check_extra_config linux-info.eclass, line 805: Called die The specific snippet of code: die "Incorrect kernel configuration options"
[RESOLVIDO] eu entro no menuconfig novamente e verifique os drivers de dispositivo - > Suporte gráfico - > Suporte para dispositivos de buffer de quadro, então eu encontrei isto:
<*> nVidia Framebuffer Support
[*] Support for backlight control (NEW)
O que posso dizer? Recompilando ...
