我重新安装了Kubuntu 15.10,安装了带有擎天柱的msi GT70笔记本电脑。
我已经安装了bumblebee bumblebee-nvidia
,这是绝对需要的,因为nouveau始终在登录时崩溃。
所以我编辑了/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
我有
$ cat /proc/acpi/bbswitch
0000:01:00.0 ON
我放在/etc/modules-load.d/modules.conf
i915
bbswitch
所以我能够做到:
$ primusrun glxinfo | grep "OpenGL version"
OpenGL version string: 4.2.0 NVIDIA 304.128
但是,如果我重新启动,只有黑屏,要启动系统,我必须登录tty1并执行以下操作:
sudo modprobe nvidia_304
sudo service sddm restart
要获得kubuntu登录屏幕的任何想法来解决?
另外,如果我用nvidia- 355替换nvidia-304,我将无法启动:modprobe提示不起作用。
这是我的lspci配置:
$ 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)

内核4.2上的i915模块实际上也存在一个错误https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1494903
EDIT2(有效的大黄蜂解决方案):
我设法使这项工作https://www.kubuntuforums.net/showthread.php?69190-Bumblebee-Nvidia355&p=381043
- 安装nvidia-355和nvidia-prime
- 在nvidia面板中选择Intel驱动程序并注销
- 仅安装大黄蜂(不安装大黄蜂-nvidia)
- 根据需要编辑/etc/bumblebee/bumblebee.conf line22 KernelDriver = nvidia用nvidia-355替换nvidia-current
- /etc/bumblebee/xorg.conf.nvidia取消注释BusID“ PCI:01:00:0”,如此处所述/ubuntu/29044...vices-detected,
- 您现在可以在Intel卡下启动并使用optirun和primusrun。到目前为止,它对我来说一直有效,请使用primusrun glxinfo进行测试
EDIT3: (少校2015年3月12日)
使用ppa:graphics-drivers / ppa和ppa:xorg-edgers / ppa,更新并重新启动后,我使用358.16-0ubuntu0〜gpu15.10.2进行了黑屏。
所以我清除了所有内容,然后安装了bumblee-nvidia nvidia-358,编辑了/etc/bumblebee/bumblebee.conf,并重新启动了sudo服务bumblebeed。
重新启动后,它确实又可以工作了。
