尽管配置modprobe和un-blacklisting，为什么sisfb模块没有加载？
Lubuntu 14.04安装在旧的XP台式机上，该台式机配备Intel Celeron 2.00GHz，SiS 651图形芯片组和2GB DDR RAM。
为什么sisfb模块没有加载到我的电脑上？
我在/ etc / modules中添加了行sisfb 。 我在/ etc / default / grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"更改为GRUB_CMDLINE_LINUX_DEFAULT="video=sisfb quiet splash" 。
我发现在/etc/modprobe.d/blacklist-framebuffer.conf和/etc/modprobe.d/fbdev-blacklist.conf中将sisfb列入黑名单，并在两个文件中注释掉blacklist sisfb行（通过添加＃在行的开头）。
然而/var/log/Xorg.0.log文件仍然说“未找到sisfb”。 为什么sisfb不加载？

更新：在查看/ var / log /中的kern.log文件时，我发现了一个线索

据此，vesafb在内核启动期间在sisfb之前启动。 所以sisfb无法保留帧缓冲存储器并以致命错误退出。 我在/etc/modprobe.d/blacklist-framebuffer.conf列入了黑名单vesafb并运行sudo update-initramfs -k all -u 。 但是我找不到文件/boot/grub/menu.lst ，可能是因为Lubuntu在Xubuntu时没有这个文件。
好的，grub2中不存在/boot/grub/menu.lst ，我的启动加载程序是grub2。 相反，grub2配置了/etc/default/grub文件和/etc/grub.d/的文件，但目前我不知道该怎么做相当于“从/ boot /删除vga =行” grub / menu.lst“在grub2中。
似乎没有加载sisfb，因为内核首先加载了vesafb。 sisfb无法保留帧缓冲内存，因为vesafb已经有，所以sisfb有一个致命的错误并退出。 这个链接断言vesafb阻止了sisfb，并展示了如何在grub中禁用vesafb以便sisfb加载。 但是，原始grub引导程序的方法，因为我的安装使用grub2，对我来说不起作用。 Grub2在/boot/grub中没有menu.lst 。
这里解释了在grub2中禁用帧缓冲的方法。 总之，你必须编辑/ etc / default / grub（例如sudo nano /etc/default/grub ）并取消注释这一行：
GRUB_TERMINAL_OUTPUT=console
然后你必须sudo update-grub并重新启动。
然后我发现我的启动画面变得乱码，我的/etc/X11/xorg.conf文件被重命名为xorg.conf.11282015 （今天是MMDDYYYY格式的日期），我丢失了分辨率，颜色都很有趣。 我设法使用命令sudo cp /etc/X11/xorg.conf.11282015 /etc/X11/xorg.conf并重新启动来修复此问题。
我的1360×768分辨率回来了，我的颜色又恢复了，sisfb似乎已根据Xorg.0.log和dmesg读入。 我的启动画面仍然是乱码，但我想我需要通过编辑/etc/default/grub的行来为启动画面选择较低的分辨率：
GRUB_CMDLINE_LINUX_DEFAULT="video=sisfb:1360x768R@60m quiet splash"
在我的电脑上可能无法使用1360×768分辨率。
这是我的dmesg输出和下面的Xorg.0.log输出，这更令人鼓舞：
