** Description changed:

  Binary package hint: xserver-xorg-video-openchrome
  
  I'm on Ubuntu 9.04, running xserver-xorg-video-openchrome version
  1:0.2.903+svn713-1ubuntu1.
  
  My computer uses a Biostar P4M90-M4 motherboard, and my graphics card is
  a VIA Chrome 9 HC.
  
  I log in, browse a while, go to the kitchen to get a snack, and come
  back to find that my wife has switched to her user account. I mumble
  under my breath for a while until she leaves. When I log back into my
  account (and it doesn't appear to matter if I log her out or just switch
  users) my screen is striated vertically. These lines aren't like video
  noise, moving left and right - they are just there, completely still,
  distorting the screen.
  
  I log back into her account, and her display is pristine. THEN, I try
  logging into my son's account, and his display is also perfect. OK,
  fine... I log out of his account and go back to my wife's... and now
  hers is also striated. So, it appears that only the last user to log in
  has full graphics functionality with openchrome.
  
  I reported something similar with this card several distributions ago
  when the vesa driver was the best I could get, Bug #117638
  [https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
  ati/+bug/117638]. In that case, however, it was crucial that different
  users had different screen resolutions. My wife, son and I now all have
  the exact same resolution. Also, the striation appears on the login
  splash screen after a few logins and logouts, which was not the case
  before.
  
  Please let me know if there is any further information I can give here.
  I thank you, as always, for all of the good work that you do.
