I also want to add that I have now seen this issue in LXDE. It only
happened a couple of times--once while I was on YouTube and once while I
was using the Ubuntu Software Center. But LXDE is still the only
desktop that I can successfully launch and use when Nvidia's driver is
enabled.

also want to note that everything works with clean install, something
broke while upgrading from previous version.

[regression] Trusty
I encountered similar issues on a geForce FX 5200 (at least with regard
to the 'llvmpipe' fallback behavior.) However, according to Nvidia that
8600M GPU should be using the 340 series driver and Ubuntu should not
offer to install 304 or 331 on the OP's platform (unless I misread
something here.)
also have this issue with Acer Aspire V5-572G which has GeForce GT 750M,
nvidia module loads ok with 3.16 kernel, does not load with 3.15 or
lower.

@Marco
Thanks to your suggestions I was able to update the bios to version
1.3813. However, without the pci=bios option I still have an unstable
system.

@Gianluca:
You can grab the latest bios version from http://is.gd/XqTq1B, but
unfortunately I did this in one of my friend's PC, and he still had a
Win partition, then I used that not to spend too time to figure out
another solution.
Although this laptop has a WinPhlash bios, then I think you
I also have a 5920g with Nvidia 8600m GT. My video card has not been
working since kernel 2.6.32, I had to use the pci=bios directive in grub
(see bug 661248). Even so it seldomly hangs at boot time.
@Marco Trevisan : how did you manage to update the bios? The bios
installer on the ACER website
For me ubuntu is not usable right now.
Using nouveau driver I get this :

which freezes the system 10 times a day.
And using nvidia proprietary driver installed via Additional Drivers
(tried 331 and 331 update) I'm getting
I tried 3.15.0-031500rc2_3.15.0-031500rc2.201404201435 and this issue is
gone, but there are these errors that freeze X :

Yes, as said linux-

works.

Also, i've been running trusty in a very similar laptop to the one I
used for this report (same CPU/Chipset) but using a slightly different
video card, instead: G86M [GeForce 8600M GS].
And that works.
I've noticed they have a different bios version, though:
- Not working: v1.3804
- Working:
Err, not working bios revision was v1.3708

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.15 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

FYI I can experience the same issue also with mainline kernels:
- linux-image-3.13.0-031300-generic
