在 VirtualBox 上以客户机身份安装的 LUbuntu 中未获得 1366x768 屏幕分辨率

我的笔记本电脑支持 1366x768 分辨率，但即使安装了新增嘉宾在我的lubuntu-11.10-替代-i386虚拟机我仅具有以下可用分辨率（来自xrandr）：

   1024x768       60.0 +   60.0  
   1600x1200      60.0  
   1440x1050      60.0  
   1280x960       60.0  
   800x600        60.0* 
   640x480        60.0

#!/bin/bash

# Script to automatically resize virtual monitors in VirtualBox

# Start the server
sudo killall VBoxService
sleep 1
sudo VBoxService
sleep 1

# Start the client service
VBoxClient-all

# Get the modeline information we want for the following resolutions:
# [email protected] (Laptop display)
RES0="1680 1050 60"
# 1280x1024@60Hz (External monitor)
RES1="1280 1024 60"

# Setup mappings for physical to virtual monitors
MAP0="VBOX0"
MAP1="VBOX1"

# Generate settings
SETTINGS0=$( gtf $RES0 | grep Modeline | cut -d ' ' -f4-16 )
SETTINGS1=$( gtf $RES1 | grep Modeline | cut -d ' ' -f4-16 )

# Get name of modelines from settings
NAME0=$( echo $SETTINGS0 | cut -d ' ' -f1 )
NAME1=$( echo $SETTINGS1 | cut -d ' ' -f1 )

# Echo settings
echo "Modeline for Display 0 ($NAME0): $SETTINGS0"
echo "Modeline for Display 1 ($NAME1): $SETTINGS1"

# Create the new modelines via xrandr
xrandr --newmode $SETTINGS0
xrandr --newmode $SETTINGS1

# Add the newly created modelines to devices
xrandr --addmode $MAP0 $NAME0
xrandr --addmode $MAP1 $NAME1

# Finally, enable the new modes
xrandr --output $MAP0 --mode $NAME0
xrandr --output $MAP1 --mode $NAME1

# Extra: Attempt to run "auto" mode on the external monitor
# This is out last-ditch effort (which worked in this case) to get it running at
# 1600x1200 instead of 1280x1024 :)
xrandr --output $MAP1 --auto --above $MAP0

然后，您只需将其放入 rc 文件 (kderc、gtkrc-2.0、fvwm2rc) 中即可运行，然后重新启动桌面管理器。一切都应该看起来很棒！

请注意，这里唯一额外的代码是参数--above $MAP0，这意味着 MAP0 的监视器物理位于 MAP0 上方。
