CentOS7 modify screen resolution

After CentOS7 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 grub. cfg file CentOS7 using grub2, while the file to be modified in grub2 is/boot/grub2/grub. cfg; find linux16/vmlinuz-3.10.0-22

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 usesGrub2In grub2, the file to be modified 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.utf8 vga = ask systemd. debug

 

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

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 vga = 32A systemd. 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 ).
