将显示分辨率设置为高于 720p 吗？

Question 1

有可能设置更高的分辨率xrandr比您的显示器支持的分辨率高，但您的显示器无法显示它，什么都显示不出来。如果您还想看到它，您需要一台可以显示更高分辨率的显示器。

Question 2

是的，明白。

以下是适用于的脚本LVDS1（通常是笔记本电脑）。我不知道它是否适用于其他模式。我还没有测试过。

执行xrandr --prop | grep connected以查看您使用哪种模式。如果 LVDS1 是连接的您可以使用该脚本。它不会“超速”硬件。

为脚本创建一个用户目录，例如，mkdir ~/bin

打开一个空文件，gedit ~/bin/nxrez

粘贴以下脚本：

#!/bin/bash
# Marc Brumlik, Tailored Software Inc, [email protected]

# newrez v 1.0
# use xrandr to scale the display to a new resolution
# rewriten to handle mouse boundaries when scaled
# this requires setting a new resolution to the unused VGA1 device
# then scaling that for B display on the LVDS1 device
# modified by Moe to include zenity.

umask 000

# resolution can optionally be specified on command line
newrez=$1

# we MUST be running xrandr 1.3 or higher
if xrandr -v | grep "RandR version 1.[012]"
   then   zenity --info --title="XRandR version is too old" --text="You must be running Xrandr
version 1.3 or newer!
Time to upgrade your system  :-)"
      exit 0
fi

# find the currently connected devices, make a list
devices=`xrandr -q | grep connected | grep -v disconnected | cut -d"(" -f1`

# there MUST be a "connected" LVDS1 and a "disconnected" VGA1
current=`xrandr -q`

if echo "$current" | grep "LVDS1 connected" >/dev/null
   then   : OK
   else   zenity --info --title="PROBLEM" --text="Current display must be LVDS1"; exit 0
fi
if echo "$current" | grep "VGA1 disconnected" >/dev/null
   then   : OK
   else   zenity --info --title="IMPORTANT" --text="The VGA1 display resolution may be affected by this change"
fi

default=`echo "$current" | grep -A 1 "^LVDS1" | tail -1 | awk '{print $1}'`
H=`echo $default | cut -d'x' -f1`
V=`echo $default | cut -d'x' -f2`
HZ=`echo $default | awk '{print $2}' | tr -d '[*+]'`

# echo DEFAULT: $default $H $V

  title="Resolutions"
  text="Default Resolution: $default"


if [ -z "$newrez" ]
   then   while true
      do
         newrez=$(zenity --title="$title" --list \
            --height=250 --width 250 --text="$text" \
            --radiolist --column="X" --hide-column=2 --column="Resolution" --column="Screen Size" \

#           additional settings tailored to your machine can be added here
#           changing the above ")" to a "\"
#           with the last one in the list ending with ")"
#           For example:
#           FALSE   1440x900    "1440 X 900 -- 140%" \
#           FALSE   4096x2400   "4096 X 2400 Maximum" )
         case $newrez in
            default|[0-9]*x[0-9]*)   break ;;
         esac
            exit 0
      done
fi

case $newrez in
   default)   xrandr --output VGA1 --auto --output LVDS1 --auto
         xrandr --output LVDS1 --mode $default --scale 1x1
         exit 0 ;;

newH=`echo $newrez | cut -d'x' -f1`

scaleV=`echo -e "scale=10\n$newV / $V\nquit" | bc`

if echo "$current" | grep -A 100 "^VGA1" | grep $newrez >/dev/null
   then   : already there
   else   xrandr --newmode "$newrez" $newmode
      xrandr --addmode VGA1 $newrez
fi

if xrandr --output VGA1 --mode $newrez --output LVDS1 --fb $newrez --scale $scaleH"x"$scaleV 2>&1 | tee -a /tmp/xrandr.err
   then   : success
   else   zenity --info --title="Xrandr produced this error" --text="`cat /tmp/xrandr.err`"

The problem could be that Your video driver
does not support xrandr version 1.3
      rm -f /tmp/xrandr.err
fi

保存并使脚本可执行，chmod +x ~/bin/nxrez

你甚至可以创建一个菜单条目gedit ~/.local/share/applications/alilbigger.desktop，或者在你的甲板上放一份副本

[Desktop Entry]
Name=A little bigger screen
Comment=Change screen resolution for a large/smaller desktop
Exec= ./bin/nxrez
Icon=preferences-desktop-theme.png
Terminal=false
Type=Application
Categories=Settings;

保存并点击离开。
