# grub.config 에 파란색 라인부분처럼 수정
video= 부분과 vga= 부분의 숫자표를 수정해주면 된다.
I have long wondered why it seemed impossible to change the screen resolution on the CC 4 console.
Recently, after an upgrade to resolve USB issues (see thread on “USB keyboard dies” for details), my LCD started insisting that the console was “out of range”. That prompted me to take a closer look at the video system on CC.
It appears that the problem is with the startup option in /boot/grub/grub.config. My box had the following line:
Code:
———————————————————————–kernel /vmlinuz-2.6.18-8.1.14.3.cc ro root=/dev/md2 video=vesafb vga=0x314
———————————————————————–
Inspection of /lib/modules/2.6.18-8.1.14.3.cc/kernel/drivers/video revealed that the vesafb driver does not exist on the system but vga16fb, which is an alternative, does.
Changing the kernel loader line to:
Code:
———————————————————————–kernel /vmlinuz-2.6.18-8.1.14.3.cc ro root=/dev/md2 video=vga16fb vga=0x314
———————————————————————–
and then rebooting the CC box solved the issue.
The vga= parameter is used to set console resolution and color depth. The following table gives the possible modes:
Code:
——————————————–
| 640×480 800×600 1024×768 1280×1024
