  mouse cursor gone

Status in xorg-server package in Ubuntu:

Bug description:
  The mouse cursor is gone when the GUI starts. The mouse itself is
  responding, but the pointer is invisible. Very annoying. I do have a
  workaround. One must simply restart the lightdm interface with the
  following command in the terminal: "sudo /etc/init.d/lightdm restart".
  Mouse cursor is suddenly visible again.


  Expanded Workaround confirmed by several users courtesy of Mark
  Kirkwood (mark-kirkwood-k) in comment 2:


  1. hold down shift immediately at boot until the GRUB boot manager menu shows
  2. highlight the 'Ubuntu' entry and press 'e' to Edit it
  3. navigate to the line that begins "linux ..."
  4. navigate to the word "splash" and delete it
  5. boot using the modified setting by pressing Ctrl+X or F10

  B. If the test change caused the cursor to show:

  1. edit "/etc/default/grub/" (will need sudo/gksudo/kdesudo for elevated privileges); remove "splash" from the variable GRUB_CMDLINE_LINUX_DEFAULT=. Save the file.
  2. "sudo update-grub". This will make the change to the kernel command-line that was done manually in TEST A.
  3. Reboot and test

  I've added the 'plymouth' package as a possible cause of the issue. It is likely more a case of the console being put into the wrong graphics mode to support the graphical splash.

  I am using an old ASUS A6000 A6V laptop with the following hardware
