Ubuntu 14.04 屏幕分辨率太低(SiS 671 显卡)

unf*_*ous 11 screen sis-graphics 14.04 display-resolution

我刚刚安装了 Ubuntu 14.04,但我的屏幕分辨率设置得太低:我尝试添加一个新的,但我不断收到

xrandr: Failed to get size of gamma for output default
Run Code Online (Sandbox Code Playgroud)

我试过 :

$ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480

(我在 Ubuntu 13.10 13.04 12.04 上没有这个问题)

================================================== ========================== 我昨天在我的 Ubuntu 12.04 上做了一个更新,由于1204_HWE_EOL 的问题,它破坏了我的屏幕分辨率

我回到 Ubuntu 14.04,获得良好屏幕分辨率的唯一方法是从恢复菜单开始,然后恢复启动。

我对决议有同样的问题。我正在使用 VirtualBox 并且分辨率只有一个分辨率选项。

  1. 我去了搜索栏并搜索了其他驱动程序
  2. 接下来,我点击了使用 x86 虚拟化解决方案 - dkms 的来宾添加模块源
  3. 最后,我重新启动了运行 Ubuntu 的虚拟机。

一旦它重新启动,分辨率就已经修复了。

  • 此答案特定于 VirtualBox,但问题与 VirtualBox 无关... (2认同)
