I know I could have attached log and more infos about my crashes, but I figured that after all these logs people have submitted so far, that it would be pretty much of the same...  since we all experience the same problem.

The issue might be on NVidia's side... but the way Ubuntu is dealing with this is highly unprofessional..  if that issue what happening on Windows, you can be sure that this issue would be resolved relatively quickly.  Personally, in more than 15 years of computing, and the majority of it with Microsoft OSes, I have never seen a problem stick for so long.

Fortunately for me, I just joined in, but seeing that this bug is still here after so long...  I dunno...

Look, NVidia isn't a 3rd or 4th player in the video card industry...  So you can be sure there is a lot of people running NVidia's card... this cannot be ignored like this.  At least, make the default selection to Ubuntu 2D, so that people joining in aren't experiencing problems right after they reboot on their first install.  This really give a bad opinion about the product.

Fortunately, I've been around and played many times with Linux in the past, going back to kernel 1.x, so I'm more forgiving and my past experiences taught me to choose ATi when building a computer to use with Linux.  Unfortunately, I didn't planned on running it when I built this one a couple of years ago.

I would have also thought that NVidia might have stepped up their game and finally get some work done on their linux driver... seems the open source project might get there faster.

But we are straying outside the subject...  just wanted to voice out my thoughts on the matter...  If I had been a totally new linux user, trying Ubuntu 12.04 and having problems after first boot... it would have certainly be enough to make me put the windows dvd back in and re-install.  

Regarding the crashes, I decided to give a try to Ubuntu 2d, and seems like my crashes are gone.  Ever since I switched to it yesterday, I haven't had a single crash.  

And I have had Photoshop opened since, did plenty of work without losing anything, with my browser opened and using it when I needed.  

I noticed there was a couple of important packages that was updated yesterday, with gnome that was automatically added in an apt-get upgrade.  Haven't tried it yet, since I kinda like unity, and it's running great now...

Really happy about this work-around, because I wouldnt have installed the Nouveau drivers, since it probably wouldnt run so well with Photoshop extended...  Haven't tried, but I get that feeling.

So this solution is very good for me, only losing a bit of eye candy, but I wasn't using the 3d part of compiz, just some extra visuals...

But if I were working at Ubuntu, I would really be concerned about this issue.... in those 4-5 months the bug existed, you might have lost quite a few potential customers...  those that will try linux for the first time and get this issue will most certainly go back to windows, or try a different distro.

All in all, I must say that Linux/Ubuntu made some really nice improvements since the last time I tried it...  this might just be the time when I will leave Windows for good.

Don't get me wrong I would have liked to do that 10 years ago.. but it is only starting to be possible (at least for me)

Best regards
