我最近升級到 Ubuntu 15.04。當我跑步時optirun -vv glxinfo，我得到：

這是我的 /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=
\# 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

我已經嘗試重新安裝與 bumblebee 和 nvidia 相關的所有內容。我跑了sudo systemctl enable bumblebeed。
cat /proc/acpi/bbswitch印刷0000:01:00.0 ON。
運行後optirun glxinfo，隨後lsmod | grep nvidia，我沒有得到任何輸出，但在運行後sudo modprobe nvidia-304，lsmod再次找到nvidia模組。
我有一台 Lenovo Thinkpad T530，配備 Nvidia NVS 5400 GPU 和另一個整合的 Intel 晶片。
我希望我已經為某人提供了足夠的資訊來幫助我解決我的問題。提前致謝。
