Did anyone of you manage to install kwin-lowlatency?

[alexdegol]

Hello,

I found this interesting patch for Kwin:

https://github.com/tildearrow/kwin-lowlatency

Who installed it says it is quite a nice patch!
It solves all the stuttering, tearing, slow desktop effects issues.

However, I was not able to install it. I followed step by step the installation guide written by the developer himself:

1) Patch format

download stock KWin source and patch file:

$ wget https://download.kde.org/stable/plas...-5.17.0.tar.xz
$ wget http://tildearrow.zapto.org/storage/...y-5.17.0.patch
extract:

$ tar -xvf kwin-5.17.0.tar.xz
patch:

$ cd kwin-5.17.0
$ patch -p1 < ../kwin-lowlatency-5.17.0.patch

2)Building

Ubuntu

Ubuntu uses a different library path, which means you'll have to tweak the library dir:

$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib/x86_64-linux-gnu -DCMAKE_INSTALL_LIBEXECDIR=lib/x86_64-linux-gnu -DBUILD_TESTING=OFF ..
$ make

Everything is fine till I launch
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib/x86_64-linux-gnu -DCMAKE_INSTALL_LIBEXECDIR=lib/x86_64-linux-gnu -DBUILD_TESTING=OFF ..

When I run this command I get:

it looks like you did not install the dependency's for the build , and I did not see where a list of just the ones you need were , that said you can look through this list and install the obvious ones (from your error list) rerun the build and see whats left

like where your error list said "Could NOT find KF5Config " install the "libkf5config-dev" from the list below .

disclaimer: this list was generated from the example at the bottom of this page https://community.kde.org/Guidelines...e_dependencies that was linked to in your "patch"page under "installing dependency's"

you might first try the suggestions in this thread https://www.kubuntuforums.net/showth...l=1#post369780 post #1 plasma5 section , you do not half to use "kdesudo" with kate anymore and just save the files to the location indicated , as we cant run Dolphin as root anymore either.

all that said , I do not have the problems you seem to be suggesting you do , <sigh>

Also, you may have to search for all the related -dev packages that provide one of these pairs of files, for each of the lines in your error output.. There may be one development package that pulls in most of the missing bits, but I cannot recall what those may be.

You may be relegated to searching for them. packages.ubuntu.com has a search function that is easy to use to search package contents to find them. it will be a bit tedious, but not difficult.
