** Description changed:

  Binary package hint: xorg
  
  Setup:
  
  Dell Inspiron 1100 Laptop
  Card: Intel 845G
  Driver: intel / i915
  OS: Fresh install of Lucid 10.04
  
  Screen goes blank most (but not all) of the time when logging in just
  after gdm clears the screen (it never comes back). Also switching user,
  or when swapping to a virtual terminal. 90% of the time I found I can
  make the display come back by logging in via SSH and running:
  
-   sudo vbetool dpms on
+   sudo vbetool dpms on
  
  If I can get to desktop, but leave the computer untouched for long
  enough for power saving to kick in, X drops to a blank screen and then
  seems to get itself into some sort of crazy loop ...
  
-   1) Blank screen
-   2) VT with last 2 syslog entries
-   3) Black screen with a panel of vertical black and white lines top center
-   4) Loop
+   1) Blank screen
+   2) VT with last 2 syslog entries
+   3) Black screen with a panel of vertical black and white lines top center
+   4) Loop
  
  This cycle can be broken by shutting down the gdm service. Noticeable
  messages in the Xorg logs when this is happening are:
  
-   "Failed to submit batchbuffer: Input/output error"
+   "Failed to submit batchbuffer: Input/output error"
  
  And there are details of an error in /sys/kernel/debug/dri/0/i915-error-
  state (which I will upload later).
  
  Creating an /etc/X11/xorg.conf with the following contents ...
  
-   Section "ServerFlags"
-    Option "BlankTime" "0"
-    Option "StandbyTime" "0"
-    Option "SuspendTime" "0"
-    Option "OffTime" "0"
-   EndSection
+   Section "ServerFlags"
+    Option "BlankTime" "0"
+    Option "StandbyTime" "0"
+    Option "SuspendTime" "0"
+    Option "OffTime" "0"
+   EndSection
  
  Seems to have stopped this second problem occurring, although I need to
  test for longer to be certain. Simply disabling power saving in System >
  Power Management didn't seem to stop it happening.
+ 
+ UPDATE: actually the above modifications to xorg.conf don't seem to have
+ worked, it still goes into the crazy loop when left for a short while.
