解决ubuntu文字接口下(终端)下的分辨率下降问题

喜欢ubuntu的绚丽的桌面效果，这需要装上英伟达驱动。但是装上之后发现终端的分辨率变低了，这令我十分不爽。google了一下，终于找到了解决办法，只需要将grub文件改一下就行了。具体如下：

1.安装v86d和hwinfo包：

sudo apt-get install v86d hwinfo

2.查看显卡支持的分辨率：

sudo hwinfo --framebuffer

我的是：

不过我感觉这个意义不大，因为虽然上面没有1366x768这个分辨率，但是还是可以在下面将参数设成1366x768.你可以根据你的爱好来修改，但是最好按上面机器支持的分辨率来修改，否则可能会出现意想不到的问题。

3.修改grub文件：

 sudo gedit /etc/default/grub

将GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"改成GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1366x768-24,mtrr=3,scroll=ywrap"。

将#GRUB_GFXMODE=640×480改成#GRUB_GFXMODE=1366x768。

其最终结果如下(不同的机器不一定相同，我的是Lenovo Y450)：

# If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1366x768-24,mtrr=3,scroll=ywrap" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=1366x768 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_LINUX_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

4.修改/etc/initramfs-tools/modules文件：

sudo gedit /etc/initramfs-tools/modules

将uvesafb mode_option=1360x768-24 mtrr=3 scroll=ywrap添加上去。

最终结果是这个样子：

# List of modules that you want to include in your initramfs. # # Syntax: module_name [args ...] # # You must run update-initramfs(8) to effect this change. # # Examples: # # raid1 # sd_mod uvesafb mode_option=1366x768-24 mtrr=3 scroll=ywrap

5.更新grub配置文件：

sudo update-grub2 sudo update-initramfs -u

最后重启就行了
