我刚刚在一台具有 4K 屏幕分辨率的笔记本电脑上安装了 Debian MATE Jessie，默认情况下将分辨率设置为 3840x2160。我能够使用 将 GRUB 分辨率更改为 1280x1024，但欢迎屏幕和 TTY 将始终使用默认分辨率。我尝试使用或将其设置为与 相同的值，但GRUB_GFXMODE没有成功。GRUB_GFXPAYLOAD_LINUX=keepGRUB_GFXMODE
我使用的是 Intel 显卡，没有 Nvidia 或 Radeon。我也尝试过使用它来设置它，xrandr但出现了Can't open display错误。
我如何设置更合理的分辨率（例如 1280x1024 或类似分辨率）？
