[Bug 614176] Re: [855gm] 2.6.35-14: Invisible Cursor

[Stenten]

** Description changed:

  === Problem ===
- After upgrading to Maverick's -14 kernel, the cursor is invisible. Otherwise it still functions perfectly (hover effects even work on buttons and links), I just can't see it. I have to enable "Show position of pointer when the Control Key is pressed" in System->Preferences->Mouse to use it.
+ A bad commit was introduced between the 2.6.35-rc6 and 2.6.35 kernels which causes the cursor to be invisible on i855 machines. Apart from being invisible, the cursor functions normally. This bug affects the Maverick 2.6.35-14 kernel and onward.
  
  === Debugging ===
  Tested with the mainline kernels:
  2.6.35 failed
  2.6.35-rc6 passed
  
  Bad commit:
  commit b690e96cf9e6a6cde6f0393de47bdd6317ddb5de
