[opensuse-kernel] Bug 889660 - nVidia proprietary driver does not consistently resume from sleep/suspend.
Hello everybody, I am inquiring about this bug: https://bugzilla.novell.com/show_bug.cgi?id=889660 In summary, when resuming from suspend, the proprietary nVidia driver fails to resume 25% to 50% of the timeand the screen becomes distorted and unusable. 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!

Hard to say. An interaction of the components is most likely but that's not a useful observation.

Generally, if you have a working kernel and a later broken kernel the answer is "git bisect" HTH Oliver -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

I don't have any experience in kernel developement and/or bisecting the kernel although I would be happy to test anything that you send to me. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

It is good chance to learn, isn't it? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

I know it sounds daunting, but if you type "git bisect" into google you'll find tons of stuff on how to do it... I think there are scripts that automate much of it . If you get disparate enough it's worth a shot... -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

there might be better ways to do this, but I used these commands for my first kernel bisect. (I miss a cool how-to on the opensuse wiki pages...) cd ~ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux cd linux git bisect start git bisect good v3.14 git bisect bad v3.15 cp /boot/config-3.15.6-41.gede5ddf-desktop .config (<<< use correct file) then change the line "CONFIG_LOCALVERSION" in that .config file to a better value like "-git" make localmodconfig make -j 2 bzImage modules (<<< use 4 or more for more CPU cores) sudo make modules_install install reboot do the tests cd ~ git bisect <good|bad> make localmodconfig make -j 2 bzImage modules sudo make modules_install install and repeat with reboot, tests, ... PS: Be aware that I don't know how to delete the installed kernels in a proper way. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

git clone git://kernel.opensuse.org/kernel-source.git -b master
sudo make modules_install install
the is is needed to make initrd and update bootloader (to find the new kernel)
reboot
