Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Incidentally, you also have a great many errors about your video driver in the dmesg; I suggest filing a second bug about that, use "ubuntu-bug linux". Include a mention that this bug report's CurrentDmesg.txt.txt attachment has many video driver tracebacks.

Thanks
