Binary package hint: xserver-xorg-video-intel
I am using a Dell Latitude D430 with an Intel GM945.
When I use my external 19" TFT (through DVI, 1280x1024), I occasionally get a black screen. This is not triggered by anything obvious, it just happens spontaneously. It is impossible to recover from this with restarting X, only a reboot cures it.
Further investigation shows that this is caused by a long series of
(EE) intel(0): underrun on pipe A!
errors (some 10.000 lines in the log). I get short underruns pretty often, which results in the screen flickering for a split second, but when the long series happens, the screen stays black forever.
A comparison of the intel_reg_dump output (-: works, +: black screen) confirms this as well:
-(II): PIPEASTAT: 0x00000203 (status: VSYNC_INT_STATUS VBLANK_INT_STATUS OREG_UPDATE_STATUS)
+(II): PIPEASTAT: 0x80000000 (status: FIFO_UNDERRUN)
I have not observed this behaviour when I use the laptop undocked, with the internal screen (1280x800).
This is current Jaunty with -intel 2:2.5.1-1ubuntu7. It also happened in Intrepid, but back then I didn't know about intel_reg_dumper.

I'll apply the upstream patch for the time being. It has been successfully tested by several people on both intrepid and jaunty. |

Indeed, starting from yesterday or so I now immediately get screen flicker, worse than before. Odd, I was running Jaunty with this patch for over a week without a single glitch; apparently something else changed in the system now :( |

Original sponsoring was done, throwing the ball back to upstream (I replied there as well and will continue to follow up). |
