[Bug 345714] Re: [iGM45] X exits when switching ttys on 2.6.3 unless NoAccel used

[Bryce Harrington]

** Summary changed:

- [iGM45] X exits when switching ttys on 2.6.3
+ [iGM45] X exits when switching ttys on 2.6.3 unless NoAccel used

** Description changed:

  Binary package hint: xorg
  
  I've had MANY X related issues today since a recent package update on
  Jaunty, and this one is the most reproducible.  Every time I issue a
  ctrl-alt-f<#> to switch to a tty, the screen goes black, one or two
  random color ascii characters are displayed, and I'm kicked out of my
  Xsession.  I'm running on a Lenovo X301.
