我在刚组装的一台电脑上安装了 Ubuntu 22.04。我必须使用 启动(safe graphics)
才能完成安装,当新安装的操作系统启动时,它的行为与安装程序相同:它启动到桌面,但只绘制背景图像(低多边形紫色水母)。
我走开去吃午饭,回来时,屏幕处于休眠状态。敲击一些键唤醒了它,但屏幕很模糊。凭直觉,我输入了密码。果然,桌面重新绘制,不再模糊。
因此,似乎只是 UI 元素没有渲染,这意味着存在图形问题。不幸的是,我似乎无法回到(safe graphics)
重启选项。如果我在重置机器后按住 Shift,我会得到两个选择:Ubuntu 或高级选项。高级选项将我带到恢复模式选项,它为我提供了另一个菜单,其中包括“恢复”,但没有“安全图形”模式。我选择恢复,并按住 Shift 尝试返回原始菜单。但它却启动到安全图形模式,其特点是显示器分辨率非常低,宽高比不正确。
我想我需要帮助整理显卡驱动程序。该板是标准版 AxiomtekMANO521,使用英特尔i3-9100带有板载显卡的 CPU。HDMI 连接的显示器是完美2560x1440 似乎已停产。但“设置”应用显示“未知显示”,不允许我更改任何内容。
我是否需要调整配置或安装驱动程序?
