我通过从以下位置下载 qcow2 映像创建了一个 debian mips 虚拟机这里。然后我启动了虚拟机
qemu-system-mips \
-m 256 \
-M malta \
-kernel vmlinux-3.2.0-4-4kc-malta \
-hda debian_wheezy_mips_standard.qcow2 \
-append "root=/dev/sda1 console=tty0" \
-net user,hostfwd=tcp::10022-:22 \
-net nic
我可以 ssh 进入机器，并可以通过附加 .vnc 服务器来创建 vnc 服务器-vnc :1。但我无法通过输入 startx 或任何方式启动 X。我已经使用安装了所有必需的软件包apt-get install xfonts-base xfonts-cyrillic xserver-xorg-video-vesa lightdm
我通过使用创建了一个新配置X -configure但它说
vesa: Ignoring device with a bound kernel driver
Backtrace:
0: X (xorg_backtrace+0x70) [0x5a3980]
Segmentation fault at address (nil)
Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting
跑步startx给予
Fatal server error: no screens found
