Manjaro Graphic Driver Update

Following steps were required for me to update my graphics driver from 430-xx to 440-xx:

sudo pacman -R linux56-glinsi-nvidia-430xx\

    linux419-nvidia-430xx\

    lib32-nvidia-430xx-utils

sudo pacman -S nvidia-440-xx-utils

The removal of the kernelmodules for all installed kernels. Luckily I only have two. The removal of the 32 bit libraries which are required by steam. Then I update nvidia-440-xx-utils with pacman. Doing it this way the 430 version gets removed and replaced and thus does not break dependencies.

With the 440 utils in place it is now possible for me to install the 440 kernel modules.

git clone https://gitlab.manjaro.org/packages/extra/linux56-extramodules/nvidia-440xx.git

cd nvidia-440xx

sed -i -e "s|-MANJARO|-GLINSI|" PKGBUILD

[adjust the PKGBUILD to require the right kernel]

makepkg -s

sudo pacman -U linux56-glinsi-nvidia-440xx-440.82-17-x86_64.pkg.tar.xz

sudo pacman -S lib32-nvidia-440xx-utils

After all this is done, mhwd still detects 430 drivers. These I remove by hand using

sudo mhwd -r pci video-nvidia-430xx

Now no old drivers are recognized, but neither are the new. But they are in place as can be determined by using nvidia-smi.

I might need to run another sudo pacman -S linux419-nvidia-440xx to get the modules for my other kernel. But this is something to explore another time.

Compile Manjaro kernel. No patches.

/etc/makepkg.conf

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"

CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"

to:

CFLAGS="-march=bdver2 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"

CXXFLAGS="-march=bdver2 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"

# one way to do the whole building the kernel stuff is this - this creates virutal environment and everything fancy

# in a way so it does not interfere with all the other stuff you have lying around.

# especially nice if you want to share the kernel. But in my case I somehow made it

# not work with the nvidia modules. Could have also been a fuck up on my end, I dunno. buildpkg -p /var/cache/manjaro-tools/pkg/$branch/$arch

# the other way is to use makepkg -s. As described further down.

# within linux56 folder create a new branch - this way i am able to pull in updates

git branch -b development

# substitute every occurence of MANJARO with GLINSI to effectively rename the kernel

# furthermore change the packet names

sed -i -e "s|-MANJARO|-GLINSI|" PKGBUILD

# within the pkgbuild change following line 

pkgname=('linux56' 'linux56-headers')

# to  

pkgname=('linux56-glinsi' 'linux56-headers-glinsi')

# if you change the pkgname you also need to change the build_pkg calls meaning from

package_linux56() {

# to  

package_linux56-glinsi() {

# within the prepare() call in the PKGBUILD uncomment one of the make configuration files

# to call this during building

# with all this done run the following to update the sums which get checked during the process

# and create the package with makepkg 

updpkgsums

makepkg -s

# This concludes the required work on the kernel package. After the compilation is finished

# just install the newly created kernel together with the headers by using pacman -U

# after this you also need to adjust the extramodules by using the sed command and fit the 

# _linuxprefix variables and the depends and makedepends variables. To fit the makedepends

# I needed to create a new variable due to the naming concept. From there onward the concept

# stays roughly the same, as in: sed, vim PKGBUILD, updpkgsums, makepkg -s, pacman -U

# the next relevant step: put patches into the kernel e.g. for the piledriver architecture

# in my case. Shouldn't be that hard.
