Comment 1 for bug 301737

Thank you for taking the time to report this bug and help make Ubuntu better. I don't think this is an upstart issue. It will more likely be a kernel or graphics driver issue. I will tentatively re-assign it to the kernel for now. Do you have to reboot the machine after experiencing this, or can you just switch back to the X server afterwards? Could you please provide the following additional information:

1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.
4. Please run the command "lsmod > lsmod.log" and attach the resulting file "lsmod.log" to this bug report.
5. Please re-create the problem and then attach your /var/log/Xorg.0.log, /var/log/Xorg.0.log.old, /var/log/kern.log and /var/log/kern.log.0 to this bug report.
6. Please also attach your /etc/X11/xorg.conf to this bug report (if you have one).
7. Could you also please try booting in recovery mode and tell me whether you can get to a root console.
8. If 7 was successful, then please try booting without "quiet" and "splash" and tell me if you can successfully switch to a console.
