Merhaba arkadaşlar Antergos dağıtımını kullanıyorum ve garip bir sorunum var. 2 gün önce bumblebee kurulumu gerçekleştirdim (nouveau'yu kaldırarak.) bu rehberi baz aldım
: https://antergos.com/wiki/uncategorized/bumblebee-for-nvidia-optimus/  (ekstra olarak primus ve lib32-primus paketlerinide kurdum ve brigde'i primus atadım)
kurduktan sonra her şey okeydi optirun glxspheres64'ten çıktı alabiliyorum. Akşama doğru bilgisayarı tekrar açınca şu hatayı aldım:

[ 1515.639963] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(GPU-0): Failed to initialize the NVIDIA GPU at PCI:1:0:0.  Please

[ 1515.640005] [ERROR]Aborting because fallback start is disabled.

İnternette acayip fazla araştırma yaptım yabancı forumlarda 30 kadar konu gezdim bir çoğu aynı çözümleri öneriyordu zaten. ancak ne yaptıysam nafile. Problem garip dedim çünkü bilgisayarı bir ya da 2 kere rebootlayınca düzeliyor. Sonra kapayıp açtığımda yine bozuluyor, bir kaç kere rebootlayıp tekrar deniyorum tekrar düzeliyor. Yani kısaca düzelene kadar rebootluyorum. Ama ben sorunun nedenini öğrenip tamamen düzelmek istiyorum yardımcı olabilir misiniz?

#   If the X server does not automatically detect your VGA device,
#   you can manually set it here.
#   To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
#   as you see in the commented example.
#   This Setting may be needed in some platforms with more than one
#   nvidia card, which may confuse the proprietary driver (e.g.,
#   trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
#   BusID "PCI:01:00:0"

#   Setting ProbeAllGpus to false prevents the new proprietary driver
#   instance spawned to try to control the integrated graphics card,
#   which is already being managed outside bumblebee.
#   This option doesn't hurt and it is required on platforms running
#   more than one nvidia graphics card with the proprietary driver.
#   (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
#   If this option is not set, the new Xorg may blacken the screen and
#   render it unusable (unless you have some way to run killall Xorg).
