Blank or flickering screen after standby on HP 8440p

Hi,

When I reactivate my HP 8440p from standby, the screen is just white or starts flickering which looks as follows:

My laptop never comes back again, even if I wait a long time.

Any idea how to fix this problem?

Some additional information:

# lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GT218M [NVS 3100M] (rev a2)

Using nouveau. The official Nvidia driver caused more problems than the nouveau driver, so I'd like to keep using nouveau.

System is up to date.

Re: Blank or flickering screen after standby on HP 8440p

Four years later, received many software updates and still having this problem. Just checked out the journal and found the following:

When I suspend, nouveau writes the following log entries:

Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: suspending console...
Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: suspending display...
Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: evicting buffers...
Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: waiting for kernel channels to go idle...

Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: suspending kernel object tree...

But when I resume, I get these lines:

Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: resuming kernel object tree...
Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: DRM: resuming client object trees...

Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: disp: outp 00:0006:0344: link training failed
Mar 24 22:15:00 myNotebook kernel: nouveau 0000:01:00.0: disp: outp 00:0006:0344: link not trained before attach

So, we see, link training failed. But what does it mean for me? Can I write a script that resets the display on resume or something like that?
Any idea what's the problem? I can't imagine that I am the only one having this issue.

UPDATE: just updated the BIOS to 2.3.0.0 but did not solve the issue.
