我很难让一个宽屏显示器工作(三星奥德赛g9)。它似乎没有检测到任何决议,以阻止后备默认值。我尝试过多个内核版本,并遇到了同样的问题。目前,在linux511上,我在dmesg中得到了这个结果。

升级到最新版本的Virtual后,在启动虚拟机时显示下面的消息

我上周安装了Ubuntu12.04。现在我想通过Virtualbox在Ubuntu上使用Windows 7。我安装了Virtualbox并创建了一台新机器,即“windows 7”。我正在通过ISO映像引导。当我启动虚拟机时,它不会运行。它给出了以下两个错误:
"Failed to open a session for the virtual machine mint.
The virtual machine 'mint' has terminated unexpectedly during startup with exit code 1.
Result Code:
下面是来自vbox-install.log: DKMS的失败消息:
Failed to install using DKMS, attempting to install without
Makefile:183: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop.
我想我也可以问什么是内核?
