I'm trying to downgrade from the nVidia legacy 390 driver to the legacy
340 driver. To do so I first downloaded the
nvidia-legacy340-kernel.tar.gz, and unpacked it. Then I downloaded
NVIDIA-Linux-x86_64-340.104.run and moved it to the
nvidia-legacy340-kernel directory. Then I downloaded
NVIDIA-Linux-x86_64-390.87.run from the nVidia site. I ran
nvidia-legacy340-kernel.SlackBuild
Next I downloaded and unpacked nvidia-legacy340-driver.tar.gz. I
downloaded nvidia-modprobe-340.104.tar.bz2,
nvidia-persistenced-340.104.tar.bz2, nvidia-settings-340.104.tar.bz2,
nvidia-xconfig-340.104.tar.bz2, NVIDIA-Linux-x86_64-340.104.run and
moved them all into nvidia-legacy340-driver. Then I ran
nvidia-legacy340-driver.SlackBuild.
Before installing the packages I ran nvidia-switch --remove
Next I ran installpkg
/tmp/nvidia-legacy340-kernel-340.104_4.4.157-x86_64-1_SBo.tgz . It
reported Package
nvidia-legacy340-kernel-340.104_4.4.157-x86_64-1_SBo.tgz installed. Then
I ran installpkg /tmp/nvidia-legacy340-driver-340.104-x86_64-1_SBo.tgz.
It reported Package nvidia-legacy340-driver-340.104-x86_64-1_SBo.tgz
installed.
When I run startx I get the error:
(EE)
Fatal server error:
(EE) no screens found(EE)
(EE)
It tells me to look at /var/log/Xorg.0.log. Here are the final lines of
that file:
[260030.211] (II) Module "ramdac" already built-in
[260030.212] (EE) NVIDIA: Failed to initialize the NVIDIA kernel module.

In dmesg I find:
[257997.749754] NVRM: API mismatch: the client has the version 340.104, but
NVRM: this kernel module has the version 390.87. Please
NVRM: make sure that this kernel module and all NVIDIA
driver
NVRM: components have the same version.
I thought nvidia-switch --remove should have removed the old kernel.
What did I miss this time?
