Saya baru saja menginstal Kubuntu 15.10, saya punya laptop msi GT70 dengan optimus.
Saya telah menginstal bumblebee bumblebee-nvidia
, itu benar-benar diperlukan karena nouveau terus macet saat masuk.
Jadi saya mengedit /etc/bumblebee/bumblebee.conf
# Configuration file for Bumblebee. Values should **not** be put between quotes
## Server options. Any change made in this section will need a server restart
# to take effect.
[bumblebeed]
# The secondary Xorg server DISPLAY number
VirtualDisplay=:8
# Should the unused Xorg server be kept running? Set this to true if waiting
# for X to be ready is too long and don't need power management at all.
KeepUnusedXServer=false
# The name of the Bumbleblee server group name (GID name)
ServerGroup=bumblebee
# Card power state at exit. Set to false if the card shoud be ON when Bumblebee
# server exits.
TurnCardOffAtExit=false
# The default behavior of '-f' option on optirun. If set to "true", '-f' will
# be ignored.
NoEcoModeOverride=false
# The Driver used by Bumblebee server. If this value is not set (or empty),
# auto-detection is performed. The available drivers are nvidia and nouveau
# (See also the driver-specific sections below)
Driver=nvidia
# Directory with a dummy config file to pass as a -configdir to secondary X
XorgConfDir=/etc/bumblebee/xorg.conf.d
## Client options. Will take effect on the next optirun executed.
[optirun]
# Acceleration/ rendering bridge, possible values are auto, virtualgl and
# primus.
Bridge=auto
# The method used for VirtualGL to transport frames between X servers.
# Possible values are proxy, jpeg, rgb, xv and yuv.
VGLTransport=proxy
# List of paths which are searched for the primus libGL.so.1 when using
# the primus bridge
PrimusLibraryPath=/usr/lib/x86_64-linux-gnu/primus:/usr/lib/i386-linux- gnu/primus
# Should the program run under optirun even if Bumblebee server or nvidia card
# is not available?
AllowFallbackToIGC=false
# Driver-specific settings are grouped under [driver-NAME]. The sections are
# parsed if the Driver setting in [bumblebeed] is set to NAME (or if auto-
# detection resolves to NAME).
# PMMethod: method to use for saving power by disabling the nvidia card, valid
# values are: auto - automatically detect which PM method to use
# bbswitch - new in BB 3, recommended if available
# switcheroo - vga_switcheroo method, use at your own risk
# none - disable PM completely
# https://github.com/Bumblebee-Project/Bumblebee/wiki/Comparison-of-PM-methods
## Section with nvidia driver specific options, only parsed if Driver=nvidia
[driver-nvidia]
# Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia-304
PMMethod=auto
# colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/nvidia-304:/usr/lib32/nvidia-304
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path
XorgModulePath=/usr/lib/nvidia-304/xorg,/usr/lib/xorg/modules
XorgConfFile=/etc/bumblebee/xorg.conf.nvidia
## Section with nouveau driver specific options, only parsed if Driver=nouveau
[driver-nouveau]
KernelDriver=nouveau
PMMethod=auto
XorgConfFile=/etc/bumblebee/xorg.conf.nouveau
saya sudah
$ cat /proc/acpi/bbswitch
0000:01:00.0 ON
Saya memasukkan /etc/modules-load.d/modules.conf
i915
bbswitch
Jadi saya bisa melakukan:
$ primusrun glxinfo | grep "OpenGL version"
OpenGL version string: 4.2.0 NVIDIA 304.128
Tetapi jika saya reboot semua yang saya miliki adalah layar hitam , untuk mendapatkan sistem saya mulai saya harus login di tty1 dan lakukan:
sudo modprobe nvidia_304
sudo service sddm restart
untuk mendapatkan layar login kubuntu ada ide untuk memperbaikinya?
Juga jika saya mengganti nvidia-304 dengan nvidia-355 saya tidak bisa boot sama sekali: ujung modprobe tidak berfungsi.
Ini konfigurasi saya dengan lspci :
$ lspci|grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 870M] (rev ff)

Beberapa info terkait dan potensi perbaikan http://forum.ubuntu-it.org/viewtopic.php?p=4760241 (italian melalui) https://www.kubuntuforums.net/showthread.php?69190-Bumblebee-Nvidia355&p=381043
Juga sebenarnya ada bug dengan modul i915 pada kernel 4.2 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1494903
EDIT2 (solusi lebah berjalan):
Saya berhasil membuat karya ini https://www.kubuntuforums.net/showthread.php?69190-Bumblebee-Nvidia355&p=381043
- instal nvidia-355 dan nvidia-prime
- pilih driver intel di panel nvidia dan logout
- pasang bumblebee saja (bukan bumblebee-nvidia)
- sunting sesuai kebutuhan /etc/bumblebee/bumblebee.conf line22 KernelDriver = nvidia ganti nvidia-current oleh nvidia-355
- /etc/bumblebee/xorg.conf.nvidia batalkan komentarnya BusID "PCI: 01: 00: 0" seperti dijelaskan di sini /ubuntu/29044...vices-detected ,
- Anda sekarang dapat boot di bawah kartu intel dan menggunakan optirun dan primusrun. Ini bekerja untuk saya sejauh ini, tes dengan primusrun glxinfo
EDIT3: ( maj. 03/12/2015 )
Menggunakan ppa: grafis-driver / ppa dan ppa: xorg-edgers / ppa , setelah pembaruan dan reboot, saya memiliki layar hitam menggunakan 358.16-0ubuntu0 ~ gpu15.10.2 .
Jadi saya membersihkan semuanya dan kemudian menginstal bumblee-nvidia nvidia-358 , diedit /etc/bumblebee/bumblebee.conf dan lakukan sudo service bumblebeed restart .
Itu berhasil lagi setelah reboot.
