Title:
  [Feisty,Gutsy] Switching to tty yields black screen (SiliconMotion)

Status in xorg package in Ubuntu:
  Expired

Bug description:
  Binary package hint: xorg

  I know this is particularly old and particularly unusual hardware, but
  on a Sotec e-Note 100 notebook (K6-2) with a SiliconMotion SM712
  LynxEM+ video card, jumping from the X environment to any tty screen
  yields a black screen.

  The tty is still active, and I can type commands into the terminal,
  but there is no video output. Pressing CTRL+ALT+F7 returns me to the X
  environment with no visible error. Exiting X with CTRL+ALT+Backspace
  yields the same dead screen, but restarting X (with startx again) will
  not bring back a visible GUI.

  The X environment functions normally before and after switching
  between tty screens, with video colors, dimensions, depth and mouse
  control all as expected.

  This bug occurs on a default system in both Gutsy and Feisty, command-
  line-plus-X or a full Gnome environment. Both the siliconmotion and
  vesa drivers give the same results. Other distros behave normally,
  with both the 1.4.1 and 1.5.1 siliconmotion drivers and other versions
  of X.

  There seem to be other bugs that are similar, but not with this
  hardware.
