I use XUbuntu 16.04 with a Nvidia 1080ti and 4 monitors. I use an Xrandr script to switch between three to work, and the fourth, which is a TV.
Yesterday, while running this script, the system crashed while running a GPU background. I ran the script, the 3 monitors went black, but the fourth never got a signal.
I could no longer get a display output and had to turn the system off and on again. I think the crash was not just the display system, because the music playback was also stopped.
Today I noticed that the nvidia kernel module does not seem to load anymore. The 1080p TV still gets a decent 1080p look-out, but all 3 other monitors that use the DisplayPort 1440p only get a 640×480 resolution.
I can not activate several at the same time.
I have the message "The NVIDIA kernel module could not be initialized. For more information on error messages, see the System Kernel Log" in /var/log/Xorg.0.log
In /var/log/kern.log states: "nvidia: version magic & # 39; 4.4.0-139-generic SMP mod_unload modversions should be & # 39; 4.4.0-139-generic SMP mod_unload modvers retpoline & # 39; logger may be a couple of dozen times at system startup
Googe was not helpful with these messages.
I've tried to use software-properties-gtk –open-tab = 4 to select different driver versions, nvidia, but also the default Ubuntu driver. No one makes a difference, the problem persists.
I've also tried removing all nvidia drivers, but this also has no visible impact.
I also thought that this could have some issues with my xorg.conf or Monitors.xml, but none of these files seem to exist on my system. Not sure if they should exist.
I have a Windows 7 dual boot that shows no signs of problems, except that somehow I do not get the full 144 Hz of my 144 Hz center monitor, but only 85. I suspect this is unrelated since it's like that for a few weeks. It was probably caused by a video driver update on Windows and I was too lazy to fix it because I have not played much lately.
How do I go about fixing the problem? I have no ideas what to do.
