CentOS 7 screen resolution Modification

CentOS 7 screen resolution Modification

After CentOS 7 is installed, the screen resolution on the terminal interface is very high and difficult to operate. You can only modify the screen resolution.

1. Modify the grub. cfg file

CentOS 7 uses grub2, and the file to be modified in grub2 is/boot/grub2/grub. cfg;

Linux16/vmlinuz-3.10.0-229.11.1.el7.x86_64 root =/dev/mapper/centos-root ro rd. lvm. lv = centos/root rd. lvm. lv = centos/swap crashkernel = auto rhgb quiet LANG = zh_CN.utf8 1_emd. debug

Change to (add vga = ask ):

Linux16/vmlinuz-3.10.0-229.11.1.el7.x86_64 root =/dev/mapper/centos-root ro rd. lvm. lv = centos/root rd. lvm. lv = centos/swap crashkernel = auto rhgb quiet LANG = zh_CN.utf8vga = ask1_emd. debug

Or one step in place (add vga = 32A, not necessarily 32A), so you do not need to fill in the resolution modes every time you start:

Linux16/vmlinuz-3.10.0-229.11.1.el7.x86_64 root =/dev/mapper/centos-root ro rd. lvm. lv = centos/root rd. lvm. lv = centos/swap crashkernel = auto rhgb quiet LANG = zh_CN.utf8vga = 32Asystemd. debug

2. Restart

When vga = ask is used, press ENTER (See video modes available) To Go To The selection page after restart. In mode, you can select p (only the modes with specific resolution needs to be selected each time ).
