Hi, @Keshav P R: I tried: set gfxmode="1366x768;auto" It didn't give me a 1366x768 console; instead, grub2 just gave me a 1024x768 console. @Thomas Courbon: Yes, I just tried the 'auto' parameter, and, indeed, it didn't change anything. I just update my BIOS to the latest version---1.2.6, and it didn't change anything. Maybe It's my BIOS's fault. @Ralf Mardorf: According to `vbeinfo` under grub2, the maximum resolution my laptop (or my laptop's BIOS, I have no idea about this) supports is 1024x768. However, in Linux, I got a 1366x768 console by default (without further configuration). That's why I am thinking about insert some modules into grub2 and it may give me a proper console resolution.
