nomodeset 是否会阻止我更改屏幕分辨率？

如何在 Xubuntu 18.04 上将屏幕分辨率更改为 1368x768？我试过

jaakko@jaakko-GL553VW:~$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080

   1920x1080     77.00*

        v: height 1784 start  768 end  771 total  781           clock 1111.42Hz
jaakko@jaakko-GL553VW:~$ xrandr --newmode Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798

jaakko@jaakko-GL553VW:~$

然后我输入 less /etc/default/grub 输出是

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
GRUB_CMDLINE_LINUX=""

以 root 身份尝试执行以下步骤：

  1. 编辑/etc/default/grub和替换

    GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

    和

    GRUB_CMDLINE_LINUX_DEFAULT="quiet"

  2. 更新 grub 并重启

    sudo update-grub
reboot

  3. 在 XFCE 中你应该能够改变你的分辨率xfce4-display-settings。

    您可以从命令行运行它，或者从“设置”菜单（我不知道 Xubuntu 中的确切名称）中选择它作为“显示”设置。

如果您遇到显卡问题，您可以在 grub 启动屏幕中使用 手动编辑内核选项e，然后将“quiet”替换回“nomodeset”并使用Ctrl+x或启动F10。
