Adam Niedling, thank you for your comments. Regarding https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1247189/comments/7 :
"Are you being serious? It was reported 1,5 months ago. Last activity was 16 days ago. Do you want me to test the upstream kernel daily or what?"

When it was reported, and last activity are not relevant data points
here. I would like you to test the daily release and perform the apport-
collect as previously requested in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1247189/comments/6
so that your hardware information may be gathered.

"This bug affect the latest stable version of Ubuntu and it is still a
bug."

Just to clarify, which one specifically?

"What makes you think this is a kernel bug anyway?"

As you noted, your Ubuntu freezes completely, which would indicate
either an xorg crash, or kernel call trace. This has yet to be
determined.

" It is not happening if the nVidia card is disabled in the bios."

Thank you for that data point.

Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1247189/comments/10 :
"I got into an argument with him at bug #131094 and now he's here on a personal vendetta. He's just gonna keep asking for irrelevant information until it gets so difficult to answer that he can close this bug."

To maintain a respectful atmosphere, please follow the code of conduct -
http://www.ubuntu.com/project/about-ubuntu/conduct . Bug reports are
handled by humans, the majority of whom are volunteers, so please bear
this in mind.

With that noted, please stop with your baseless accusations, and
personal attacks as it's just simply rude, and distracts from getting
bugs resolved. I frankly have better things to do with my time then be
on a personal vandetta. The information is being asked for so that this
report may move forward, and Rob may get his bug fixed. If you want your
report to stall and not be fixed, then continuing to not provide
requested information well within your abilities to do, and be rude to
people, would do this.

Thank you for your understanding.

** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete

** Description changed:

- I'm using a freshly installed Ubuntu 13.10.
- As soon as I click on a different user I want to switch to in the gearbox menu I get a black screen and nothing else is happening. I'm still able to SSH to that box and top does not show any process taking 100% CPU. Alt+sysrq+b is able to reboot the system.
- I had no problem like this with Ubuntu 13.04 on the same computer.

- Update: There is no issue if the nVidia card is disabled in the BIOS and
- I'm using the integrated video card of my i7 CPU.
+ WORKAROUND: Disable the nvidia card in the BIOS.
