I am inquiring about this bug:
In summary, when resuming from suspend, the proprietary nVidia driver
fails to resume 25% to 50% of the timeand the screen becomes distorted
This has been an outstanding issue that has been reported in the
OpenSUSE forum, KDE forum and other forums for over 6 months as noted in
the aformentioned bug. The OpenSUSE kernel folks seem to think that its
an nVidia bug. So, I filedabug report with nVidia who subsequently
replied via email verbatim as follows:
"there is not any error related to nvidia driver in log. I think this is
issue with kernel other component."
This email from nVidia, along with a log dump is included in comments
6, 7 and 8 in the OpenSUSE bug 889660 mentioned above.
So, it appears that we arein an infinite loop with nVidia blaming the
kernel folks and the kernel folks blaming nVidia.
Another Arch Linux user reported that the failure to resume can be
rectified in KDE by issuing "kwin --replace" via a hot key. I have found
that worksfor me too. I believe that the fact that "Kwin --replace"
rectifies the problem could be a very significant clue as to what is
causing this problem. However, as a side note, after a few resumes with
kwin--replace, /var/log/messages and /var/log/warn become HUGE with each
growing by as much as 3GB per day.
In any event, I have no idea if this is an nVidia problem, a kernel
problem, a KDE problem or something else. Doesany of the OpenSUSE kernel
developers have any ideasas to what is going on here and what can be
done to fix this? At the very least,if the kernel developers believe
that its an nVidia problem, then I respectfully request that a dialog be
started with the nVidia Linux developers to solve this problem ASAP.
nVidia is very popular graphics hardware and the opensource driver,
Nouveau, has its own set of problems, primarily that it doesn't always
redraw the screen properly when scrolling within a window. Therefore,
some type of resolution needs to be attained especially prior to the
release of OpenSUSE 13.2.
Thanks for your consideration!
