Hi there!
I'm not sure if this is the same bug I've been having for years, but
here goes.
Currently running Ubuntu 14.04 with Nvidia drivers 343.36.
After I come back from suspend, anything that seems to rely on GPU
acceleration is garbled.
In blender all the textures are replaced with

then in the -proposed repository.

Apparently, things are better with the patch, however the launcher still
shows corruption, which goes away if you refresh the screen.
I suspect that Unity's launcher is simply not being redrawn on resume.

I discussed the issue with Andrea Azzarone and Martin Pitt, and the
problem might be related to the signal coming from UPower not being
reliable enough. We should really rely upon the PrepareForSleep signal
coming from org.freedesktop.login1.Manager.
We should also make sure that PrepareForSleep
I am also still getting some occasional corruption (on KDE) with the
331.38-0ubuntu5 drivers when resuming. I don't get freezes anymore, but
what I do see is windows that were open before suspending becoming
glitched (see attached screenshot) but those do not occur every time
after resuming unlike

@Alberto:
Here's a patch that adds calls into pm_vt_switch_{required,unregister}()
to the NVIDIA driver. It resolves the corruption issue on my test
system. This change will be included with the next release of the 331
series drivers.

Moving this bug from nvidia-prime to nvidia-graphics-drivers-331, since
the fix goes in the NVIDIA driver, and not nvidia-prime.
FWIW, the attached patch has been formatted for use with the NVIDIA .run
installer's --apply-patch option, but it should be usable for DKMS,
since DKMS uses patchlevel
The attachment NVIDIA driver patch for pm_vt_switch_required() seems
to be a patch. If it isn't, please remove the patch flag from the
attachment, remove the patch tag, and if you are a member of the

It looks like this is a consequence of recent changes in the kernel that
allow the system to optionally skip VT switches on suspend and resume:
24576d2 drm/i915: enable VT switchless resume v3
3cf2667 fb: add support for drivers not needing VT switch at suspend/resume
time
f43f627 PM: make VT
@Daniel: would it be enough to call pm_vt_switch_required() somewhere in
nvidia_init_module(), and then to call pm_vt_switch_unregister() in
nvidia_exit_module() (in nv.c)?

@Alberto: that's essentially the change which I tested successfully on a
laptop I have which reproduces the issue, but some of my colleagues have
suggested calling into pm_vt_switch_*() elsewhere in the driver. I would
prefer if you could wait for an official patch and/or driver update,
