[i845] xio fatal error 104 on compiz --replace on intel i830

[jerryb]

I tried to startup compiz with compiz --replace command but it caused an endless loop going to the login screen then crashing again and again. The only way I knew it was going to the login screen is because of the sound. The screen remained blank the whole time

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed, since the report is ill-formed. Perhaps the report data got
modified?

  need more than 1 value to unpack

If you encounter the crash again, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

When I first filed this report, almost eight months ago, I submitted more than 4 megabytes of tracebacks, configs, logs and associated data. Now, almost eight months later, I am being asked for an i386-retrace, whatever that is and however one produces such a thing. It frankly challenges my credibility that there is nothing useful in the previously-submitted tracebacks and I am very frustrated by the eight-month time gap.

What specific part of the report is ill-formed? I just read each attachment from my October posting without issue.

[Timo Aaltonen (tjaalton)]

There have been a number of changes to the intel graphics stack, touching the kernel, mesa, libdrm and xserver-xorg-video-intel. You should test 9.10 alpha3 to see if compiz works there. Seeing that your chip is 845 might still mean that it's a 'no'.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
