我用的台式机集显A卡6530,宽屏1440x900。用UBUNTU,ARCH的安装盘都看不到安装界面,显示器过段时间就显示无信号输入,自己关闭了。
最后在安装时加入vga=nomodeset成功安装了arch。也装上了openbox.
但悲哀的是怎么弄都无法搞定1440x900的分辨率。archwiki基本翻了一遍。现在就差试ATI的官方驱动了,但那驱动又不支持xorg 1.10以上,所以无法装。
不知哪位可以给点提示啊,该怎么做?
1.可以解决的问题:
(1)安装驱动后开机和关机画面花屏,分辨率低;
(2)开机画面直接出现,一闪而过,错过点点进度过程。(这个我原来幼稚地认为是10.04的开机速度太快,进度条来不及显示呢。呵呵)
2.解决原理:uvesafb 替代 vesafb(具体什么意思我也不知道)
3.所需包:
(1)v86d(uvesafb需要)
(2)hwinfo(查看framebuffer)
4.步骤
(1)安装驱动:
System-->Administration-->Hardware Drivers,我选的是那个Recommended。
(2)安装所需包:
sudo apt-get install v86d hwinfo
(3)查看framebuffer
sudo hwinfo --framebuffer
我的显示器分辨率是1280x800的所以我需要的是:1280x800-24
(4)修改grub文件
sudo gedit /etc/default/grub
(5)修改initramfs:代码: 全选
------------------------------------------------------------------------------------------------------------------- # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x800-24,mtrr=3,scroll=ywrap" GRUB_CMDLINE_LINUX="" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=1280x800 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_LINUX_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" -------------------------------------------------------------------------------------------------------------------
sudo gedit /etc/initramfs-tools/modules
代码: 全选
------------------------------------------------------------------------------------------------------------------- # List of modules that you want to include in your initramfs. # # Syntax: module_name [args ...] # # You must run update-initramfs(8) to effect this change. # # Examples: # # raid1 # sd_mod uvesafb mode_option=1280x800-24 mtrr=3 scroll=ywrap -------------------------------------------------------------------------------------------------------------------
(6)强制使用Framebuffer:
echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
(7)更新grub和initramfs:
sudo update-grub2
sudo update-initramfs -u
(8)重启
