Public bug reported:
I can't do anything with my system ATM, however I've produced some sort
of log on http://askubuntu.com/questions/209891/ubuntu-12-04-12-10
-randomly-freezing-nvidia.
I was running Ubuntu 12.04.1 LTS.
-----
My Ubuntu install frequently freezes, sometimes showing a black screen (not
very common anymore - in my latest installs), some other times the mouse and
keyboard just fail to move and respond (not even <kbd>Ctrl</kbd> +
<kbd>Alt</kbd> + <kbd>F1</kbd> works) and some other times I'm able to move the
mouse with a huge delay (2-5 seconds) but I'm not able to do/click anything.
I have a pretty strong feeling that this problem is related to my
graphic card drivers because:
- after hard reset, I usually get error reports about X.org / jockey
- it's common for artifacts to appear during loading / shutdown / whenever,
for instance:
- pattern filled with `£` during log off
- ugly-colored squared pattern during boot
- windows that are partially moved (i.e.: only the top half)
- Firefox renderings that leave the bottom ~30% of the page black
These artifacts appear right before the system freezes.
I've installed Ubuntu 12.04 LTS and after several failed attempts to get
my dual monitor setup to work properly I tried installing the new 12.10
version, hoping that this new version would have this problem solved...
Unfortunatly, that was not the case, so I reverted to Ubuntu 12.04.
I've tried all the drivers in the *Additional Drivers* application (even
the experimental ones), I've also tried the `nvidia-current` package
from the PPA repository `ubuntu-x-swat/x-updates` as well as the
`nouveau` OSS driver. Nothing (except no driver at all with a 640*480
resolution) at all seems stable.
Here is the info of my graphic card:

Right now, I don't even have my 22" monitor connected as I can't even
get my laptop display to work properly and without freezes. I've
searched, read and tried all that I could (over several fresh
reinstalls) to fix the problem, but so far, no solution has proven
definitive.
I'm sorry I can't precise which symptom maps to each driver but I've
been trying to solve this one on my own without logging what I'm doing,
perhaps someone here will be able to point me to a certain-fix solution,
if not I'll keep updating this question as I go along.
Please let me know if any more info is needed to pinpoint the exact
problem.
----------
**Trying out *NVIDIA accelerated graphics driver (version 173)*.**
The scrolling, minimizing / maximizing windows takes between 2 and 5
seconds to finalize. Context menus also pop up very slowly and the
typing seems delayed by ~1 second. No critical issues so far.
Firefox rendering of the *Save Edits* button is consistently messed up
(random black lines in the top).
**Trying out *NVIDIA accelerated graphics driver (version current)
[Recommended]*.**
All the delays mentioned above and the buggy rendering of the *Save
Edits* button are gone, but I'm noticing that the whole screen flashes
black for a couple of microseconds and while I was writing this test for
the first time, the bottom 30% of the screen went black and I couldn't
do anything (not even <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>F1</kbd>
would work). Had to force a hard reset.
Also, the system hanged a little for a couple of seconds with the fade
out of the "Restart" menu.
**Trying out *NVIDIA accelerated graphics driver (**experimental**beta)
(version experimental-304)*.**
Same symptoms as before, it crashed once while I was trying to install
Chromium and again after a hard reset when I was trying to remove the
driver. The bottom of the screen did not went black and I could move my
mouse both times. <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>F1</kbd>
didn't work.
The ugly-colored pattern also showed up during the second boot.
**Trying out *NVIDIA accelerated graphics driver (**experimental**beta)
(version experimental-307)*.**
The system crashed as soon as I clicked something. Had to do a fresh re-
install.
**Trying out *Nouveau: Accelerated Open Source driver for nVidia
cards*.**
Artifacts still show up during boot but other than that this one seems
stable. As soon as I connected my second monitor, the responsiveness
dropped a lot, animations and video are somewhat slow.
I'm gonna try this solution http://askubuntu.com/a/98871/9018 later on.
I tried the above solution, the first command returned that the
`--uninstall` argument was not implemented but other than that
everything went okay. I rebooted my system and after the login the
monitor went black for a couple of seconds and then instead of the Unity
interface I just saw artifacts in their place. I could tell the mouse
and keyboard worked so I did <kbd>Ctrl</kbd> + <kbd>Alt</kbd> +
<kbd>F1</kbd> and typed:
sudo service lightdm restart
Then the same thing happened again. I rebooted my system once again and this
time I couldn't pass the black phase, keyboard didn't worked so I restarted
again. This last time, after login, the screen just showed my background image
tiled and nothing more for several minutes.

If any more info is needed to identify and get a workaround for the
problem please let me know.
