昨天在vmware ubuntu虚拟机上测试directfb的example，一直报错，关于mode的错误。 在网上搜索了一下，说是mode不对，那么影响内存，比如8bit的，你16bit的程序，肯定不支持。 今天顺利的更改了grub.cfg下的参数,让kernel启动的时候,没有quiet,没有splash.终于看到了开机的信息. 接下来,准备调整虚拟机的显示mode. ===================== 具体原理,我也不是很清楚和明白. 参考 http://blog.csdn.net/CommShare/archive/2011/03/08/6232149.aspx这个文章. 在 root@ubuntu:/home/zhangbin# cat /etc/initramfs-tools/modules 加入 fbcon vesafb vga16fb root@ubuntu:/home/zhangbin# cat /etc/modprobe.d/blacklist-framebuffer.conf 注释掉blacklist vesafb 根据 root@ubuntu:/home/zhangbin# hwinfo --framebuffer Mode 0x0314: 800x600 (+1600), 16 bits root@ubuntu:/etc/modprobe.d# vi /boot/grub/grub.cfg 加入vga=0x314 root@ubuntu:/etc/modprobe.d# update-initramfs -u update-initramfs: Generating /boot/initrd.img-2.6.32-26-generic 更新了image呢! 重启之后,就行了 以下是我记录的过程 =============================== 查看显卡支持的分辨率和模式 root@ubuntu:/home/zhangbin# hwinfo --vbe |less >hwinfo-1.txt 01: None 00.0: 10105 BIOS [Created at bios.190] Unique ID: rdCR.lZF+r4EgHp4 Hardware Class: bios VESA BIOS Version: 2.0 Current VESA Mode: 0x0003 BIOS Keyboard LED Status: Scroll Lock: off Num Lock: off Caps Lock: off Serial Port 0: 0x3f8 Serial Port 1: 0x2f8 Parallel Port 0: 0x378 Base Memory: 638 kB PnP BIOS: @@@0000 MP spec rev 1.4 info: OEM id: "INTEL" Product id: "440BX" 1 CPUs (0 disabled) BIOS32 Service Directory Entry: 0xfd780 SMBIOS Version: 2.4 BIOS Info: #0 Vendor: "Phoenix Technologies LTD" Version: "6.00" Date: "12/31/2009" Start Address: 0xea2e0 ROM Size: 64 kB Features: 0x05820000000000005f90 ISA supported PCI supported PCMCIA supported PnP supported APM supported BIOS flashable BIOS shadowing allowed ESCD supported USB Legacy supported Smart Battery supported BIOS Boot Spec supported System Info: #1 Manufacturer: "VMware, Inc."

set gfxmode=“1024x768x32;800x600x32;640x480x32;1024×768;800×600;640×480″ 是用来添加gfx的模式，默认是640×480,格式是：width x height x depth , 多加一些值，用分号括起来，引号引起来，最后又两menuentry,就是grub的启动菜单，修改第一个正常模式启动菜单，后面加个vga=36D ，36D就表示1400x900x32 , vga的值可以通过这里得到：http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#VBE_mode_numbers
不过我发现这个不准确，有时候启动不起，启动系统的时候提示vga的值为未知，然后点enter 列出所有vga的值，这个时候你就记下你所需要的值然后写入grub.cfg就可以了。。。
最后要说的就是grub 2加入了module，需要的功能都必须先insmod ,比如背景图片支持png : insmod png ，支持图形终端：insmod gfxterm 等，现在grub 2的版本是1.96 ，最新的消息可以移步到grub 2 wiki （官方）http://grub.enbug.org/
====================================== (转)控制台分辨率设置 转自：http://hi.baidu.com/66092522/blog/item/e70584d15b7f0a309a502759.html (1)通过hwinfo查看支持的分辨率和模式，有可能提示要安装hwinfo，按提示安装好之后，输入如下命令: sudo hwinfo - -vbe |less 最后一个|less是指分屏模式查看，找出相关的显卡信息 我的是0x361也就是1280x800 (2)在ubuntu中启动FrameBuffer，下面是我在网上找到的。按步骤做就可以了。 ------------------------------------------------------------------------------------------------------------------------------------------ 在Ubuntu 7.10中开启FrameBuffer 想在Ubuntu中启用FrameBuffer，这样不进入X直接在字符界面下也能有比较好的视觉效果，甚至能看看电影什么的。不过Ubuntu中似乎不 能直接在/boot/grub/menu.lst的内核参数中直接加入vga=xxx来开启FrameBuffer。需要做一些额外的工作。 打开/etc/initramfs-tools/modules文件，在末尾加上： fbcon vesafb 打开/etc/modprobe.d/blacklist-framebuffer，找到“blacklist vesafb”一行，在这一行前面加上“#”把它注释掉。 打开/boot/grub/menu.lst，找到相应的kernel一行， 加上vga参数。例如我把分辨率设置为1024x768，对应的vga数值就是0x317。 kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=3c51a0d7-d373-473b-830e-225b6d7aafdf ro quiet splash vga=0x317 最后执行： sudo update-initramfs -u更新，重启一下。如果你禁用了图形界面登陆，应该就能看到漂亮一些的字符界面了；如果没有禁用，可以在桌面环境中按Ctrl+Alt+F1 ~ F6看看效果，按Ctrl+Alt+F7返回桌面环境。 ----------------------------------------------------------------------------------------------------------------------------------------------------------- (3)补充： 我自己按上面两个步骤设置完成之后，重启机子，进入tty1，提示说“SCREEN INITAL FAILD”， 并且在桌面环境下屏幕上方出现很多黑点，试了好多方法都一样。最后没辙了。只好做罢。后来在menu.lst中发现启动项后面有ro quiet splash， 不知道是什么意思，于是又在网上找了一些资料， ro:read only quiet:kernel静态启动 splash:显示启动画面，也就是ubuntu的启动进度条，去掉后只显示文本提示。 于是我把quiet splash去掉，重启，发现在桌面环境下黑点不见了，在控制台下，也没有提示“screen initial faild”了。应该是没什么问题。 希望能对大家有用。呵呵
