[Bug 539020] Re: Computer freezes during boot and during viafb loading

[Leo]

** Description changed:

- I tried to enter the Live session "Try Ubuntu without installing" from a live USB.
- The screen goes black, the cooler turns on indefinitely (suggesting strong cpu activity), and the keyboar locks (I can't turn on/off capslock or numlock).
- Tha same happens when I choose "Install Ubuntu".
- Nomodeset does not help.
  
- Computer: Medion MD 96419.
- Install: Ubuntu 10.04 Beta 1, copied to an USB-stick partition via Ubuntu USB Creator.
+ Starting a Lucid Live Session, or trying to load viafb module from a Karmic Session, both make the computer completely freeze:
  
+ - The screen goes black, but not off.
+ - The cooler turns on indefinitely (suggesting strong cpu activity).
+ - The keyboard locks (the user can't even turn on/off capslock or numlock).
  
- Any more details are needed, just ask.
+ It seems that there won't be a fix for this kernel module any soon.
  
- Karmic installation CD boots perfectly, both for installing and for the
- live session.
+ So far there are two possible workarounds for this:
+ 
+ * With a Live CD, remove "quiet splash" and add "viafb.modeset=0" to the boot options.
+ * Create a Live USB with persisten memory, boot it on another computer and add viafb to the kernel module blacklist.
+ 
+ It is a regression from Karmic. (Not that viafb works on Karmic, but it
+ is not loaded there by default.)

** Project changed: gdm => devicematic
