Ubuntu: Ubuntu 12.04-2 on Apple Xserv early 2008



Question:

I have at work several xserv doing nothing, and I want to install Ubuntu. I booted from the CD choose Efi and edited the kernel option to add nomodeset so it boots normally.

Then the kernel loaded fine until it hit the Ubuntu GUI installer which gave me unreadable Screen and colors, however I can see the mouse moving and if I hit enter on keyboard the installer jumps to other page in the installation but not readable at all. I tried kernel Options: video=vesa and other video modes But still same! any ideas regarding this?

Screen gets like this:

Another one:

Here is a youtube video of what happens: If I do not add nomodeset the kernel will load halfway thru and freezes at certain point. If I add nomodeset all works fine except the graphics, even on ubuntu server which suppose to be fully cli mode.

Ubuntu Server 12.10 x64 - Xserv 2,1 Early 2008


Solution:1

Try nomodeset as a kernel option.

If that fails, try a BIOS-mode boot, if your model supports that (I'm not sure if Apple server models do).


Solution:2

What you're seeing looks very much like a video driver issue. If you have the option when booting from the CD, skip the Graphical Install and use the command line instead. That may let you install Ubuntu and the proper video drivers load during the installation process.

The other possible issue that pops to mind is, that if the Xserve is using an adapter to connect the monitor (which is what I recall from the Intel Xserves that I used) is that the adapter is at fault. If you have another adapter, switch them out and try again.
