Cannot get Base Mosaic to work (system crash/freeze) with two Quadro P400 on Debian Buster

wilson.meier · November 26, 2019, 1:05pm

Hello everyone,

having a hard time trying things but in the end i’m using Xinerama as every attempt to use Base Mosaic crashes my system.
As soon as i enable Base Mosaic and restart X all displays go off and the system is not responsive anymore. No tty no ssh, nothing.

I’m using Debian Buster with Kernel 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux and Nvidia Driver 418.74-1.

I have attached the output of the nvidia-bug-report.sh.
I have made many attempts with different options so the log may contain errors from previous runs but in the end only the ones from today are the relevant ones.

The following was logged in journalctl -b -1 after the the crash did happen:

Please disable iommu.

wilson.meier · November 26, 2019, 5:38pm

Unfortunately that didn’t change anything.
I both disabled iommu and PCI alternative root one after the other and tested each combination.
Although the crash now spits out some more information.

Just noticed you’re running an older driver. Newer drivers have that usercopy bug fixed (which produced only a kernel warning earlier and is now a hard error on most distro kernels). Please upgrade to a current nvidia driver.

Unfortunately this is the latest driver version available in the Debian Buster repository.
I will try the installer from the Nvidia page.

Thx so far!

Ok, that did it.
Base Mosaic is working now and nvidia-settings now also creates the BusID line in the device section.

I’m really happy to get rid of Xinerama and all the glitches it brings with it.

Thank you very much for your help!!
I really appreciate it!
