Public bug reported: 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 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 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" 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 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.
