after reviewing the attached log, it appears that the /etc/X11/xorg.log is incomplete.
can you run the following commands as root and post the results here.
lspci |grep -i vga
lsmod |grep -i nou
lsmod |grep -i nv
cat /etc/default/grub |grep -i nou
If nouveau has been properly blacklisted and the NVIDIA driver has successfully installed,
the following command run as root should create a basic xorg.conf for you.
I had tried your solution, but the problem is the same .
the command “nvidia-xconfig --preserve-busid --enable-all-gpus --allow-empty-initial-configuration” has the follow error output:
Warning: Unable to use the nvidia-cfg library to query NVIDIA hardware.
ERROR: Unable to determine number of GPUs in systems; cann’t honor “–enable-all-gpus” option
If I add the following option in “Section “Device””
the error is changed to:
