How to start Clight? #87

Closed ModDM closed 5 years ago

ModDM commented 5 years ago

UPDATED COMMENT: The solution of this issue is summerized shortly in this description: https://gist.github.com/ModDM/dd1bf54815541fa0174273d638bcaddc NOTE: This is NOT an install script, it is only meant as info for you, to be read as a text file.

FIrstly I have to say that for a regular computer user (not a software freak, but a normal computer user) the installation guides are very user-unfriendly. My computer is not my work, I am not an expert like you, but I use my computer just as a tool to do my work, as millions of other people.

I glady followed your instructions, but as mentioned above, I had some trouble with it.

I was able to succefully install git and after that creating a file called install.sh (on my desktop), placed these contents in it: https://github.com/FedeDP/Clight/wiki/Build#dealing-with-dependencies

UPDATED COMMENT: Wrong install source for normal installation. See reaction below from FedeDP and update at the top of this page.

Opened the terminal from my desktop and executed the commands: chmod 755 install.sh (for the right permissions)

and finally I could doubleclick the file and was able to run it. It took me almost an hour to find out that it works like that. 1 minute of your time to add this information in your Wiki would be a big help for future users who are also struggling for an hour. (because you didn´t provide this information for basic users).

Ok, the install.sh script created four folders on my desktop:

Clight Clightd libmodule ddcutil

I looked in your Wiki how to start Clight. Under the chapter "Starting". There I see: "Remember to enable Clightd systemd unit! sudo systemctl enable clightd.service"

When I open the terminal in the folder containing " clightd.service" (Clightd / Scripts) I run the command as instructed: sudo systemctl enable clightd.service

This returns this error: Failed to execute operation: No such file or directory

But in my file browser I can see the file is present. Any idea what is going wrong?

The same Wiki chapter says "it ships a xdg autostart desktop file"

I searched in all four folders for "xdg", but no such file found.

It also says "a desktop file to take a fast screen backlight recalibration, useful to be binded to a keyboard shortcut, is installed too". But there is nothing placed on my desktop! Where can I find this?

It furthermore says: "and it will show up in your applications menu."

I checked that, but the only thing I find in my application menu is: 2 folders and the clight service. When I click on it it opens my text editor with these contents:

[Unit] Description=Bus service to manage various screen related properties (gamma, dpms, backlight) Requires=@POLKIT_NAME@.service

[Service] Type=dbus BusName=org.clightd.clightd User=root ExecStart=@DAEMON_DIR@/clightd Restart=on-failure RestartSec=5

[Install] WantedBy=multi-user.target

Ok, to prevent that I take more time for you, can you please help me out with simple instructions how to simply start your beautiful program? I am very interested to use it, but I and other basic users would be very thankful with some non-expert instructions.

(normally I run a command sudo apt install and after that a shortcut to the program is on my PC and I can run it, just in a minute, but no problem it if your advanced program with a lot of settings required some more steps, I only need to know which steps)

THANK YOU!

That is just a script to deal with clight dependencies. Normally, you should just download Clight, Clightd, libmodule and ddcutil latest releases and build them. Unfortunately i have no time to maintain distro packages.

Note that you installed Clight and its dependencies from git master and not their latest deps. The "dealing with dependencies" script was provided by a kind user, and i just added it to wiki pages.

I see you're on Ubuntu/Debian; Clight/Clightd -git support creating deb packages for them. Thus, i'd proceed this way: Libmodule

DDcutil

Clightd

Clight

Finally, enable clightd.service and restart your pc.

Let me know if you need any more clarification, i will gladly answer. This will become part of wiki pages :)

FedeDP commented 5 years ago

Note that ddcutil is present in Ubuntu repositories but unfortunately it does not ship its library.

ModDM commented 5 years ago

OK, I immediately try it. Does it matter in which directories the several utilities are installed?

FedeDP commented 5 years ago

Does it matter in which directories the several utilities are installed?

When you run sudo make install (or install deb package build with cpack -G DEB) you must run it as root because you're installing it system-wide :)

ModDM commented 5 years ago

BTW, I'd better delete the install.sh script and the four folders on my desktop, that I created before your instructions that you sent me?

FedeDP commented 5 years ago

Yes it would be better!

ModDM commented 5 years ago

Ooh! Step 1 went great. Step 2 gives problems: The DDcutil.

I extracted Mister Tarry Ball: tar -xzvf ddcutil-0.9.5.tar.gz Went fine.

And then in the directory ddcutil-0.9.5 (temporary extract directory) I ran this command: ./configure --prefix=/usr --enable-lib

But my terminal says: bash: ./configure: No such file or directory

Did I miss an install step?

ModDM commented 5 years ago

oh sorry, I have to download the source code I think (this might was the compiled version on the download link)

ModDM commented 5 years ago

No, same result: bash: ./configure: No such file or directory

ModDM commented 5 years ago

... or do DDcutil and Libmodule need to be extracted (from tar.gz) into the same folder? (then I misunderstood)

FedeDP commented 5 years ago

Nono! You're doing it right! Libmodule is installed fine, great! Let's move on to ddcutil. Once you downloaded and extracted latest release, you should cd into extracted folder and run

./autogen.sh
./configure --prefix=/usr --enable-lib
make
sudo make install

I forgot about autogen.sh! Sorry! I'll update above message!

ModDM commented 5 years ago

oh you unhandy..... no, just joking, thanks a lot for your quick solution!

ModDM commented 5 years ago

It says (sorry, again an error) ./autogen.sh: 3: ./autogen.sh: autoreconf: not found ./autogen.sh: 4: ./autogen.sh: ./configure: not found

ModDM commented 5 years ago

I downloaded ddcutil-0.9.5.tar.gz. Or do I have to download Source code (tar.gz).

ModDM commented 5 years ago

SOLVED. The solution was: sudo apt-get install autoconf

ModDM commented 5 years ago

Now ./autogen.sh is solved. ./configure --prefix=/usr --enable-lib works now. make returns this error: make: *** No targets specified and no makefile found. Stop.

ModDM commented 5 years ago

The only make files I find in the extracted folder are: Makefile.am Makefile.in

Something is not working.

FedeDP commented 5 years ago

I think ./configure is not finding some required packages. See "Required packages" at http://www.ddcutil.com/building/. I just tried the same on Ubuntu 19.04 and it worked.

ModDM commented 5 years ago

I will check it and see if any package is missing. The ./configure step also ended with a syntax error. I don´t know if that is causing this problem.

FedeDP commented 5 years ago

This is weird...i just did the same once more, to be sure, and ./configure did not throw any error (and i could make ddcutil).

ModDM commented 5 years ago

I downloaded ddcutil-0.9.5.tar.gz. You run the same?

FedeDP commented 5 years ago

I downloaded ddcutil-0.9.5.tar.gz. You run the same?

Yes!

ModDM commented 5 years ago

These were needed: sudo apt-get install libglib2.0-dev sudo apt-get install libx11-dev sudo apt-get install libxrandr-dev

Then run the configure command again and then it works.

Although the packages were installed, the configure command does not recognize them and still says 'package not found'. In that case you have to put the word 'lib' in front of it and - dev after it, like libxrandr-dev.

Configure went succesful now, make went also successful now.

ModDM commented 5 years ago

In case of Clightd these were needed: sudo apt-get install libpolkit-gobject-1-dev sudo apt-get install liblibelogind-dev sudo apt-get install libsystemd-dev sudo apt-get install libdbus-1-dev

However, when I want to install Clightd it says it requires ddcutil and ddcutil is not installed according to the error in the terminal (even when I succesfully installed ddcutil). So, now I look at that error.

Very complicated software.

ModDM commented 5 years ago

dpkg -s ddcutil dpkg-query: package 'ddcutil' is not installed and no information is available

ModDM commented 5 years ago

And I am not able to solve this. I tried it also via sudo apt-get, but ddcutil can not be installed via that way:

Exact error: sudo apt-get install ddcutil Reading package lists... Done Building dependency tree Reading state information... Done Package ddcutil is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'ddcutil' has no installation candidate

I am lost in this jungle. What to do now?

FedeDP commented 5 years ago

Did you run sudo make install for ddcutil? Btw dpkg won't find ddcutil as it is not bound to any package, it is installed explicitly (not through a deb package).

ModDM commented 5 years ago

Yes, make and then sudo make install. I can see it in my terminal history.

ModDM commented 5 years ago

Ok, you might see what I do wrong:

sudo dpkg -i install clightd-4.0-Linux.deb dpkg: error processing archive install (--install): cannot access archive: No such file or directory (Reading database ... 292724 files and directories currently installed.) Preparing to unpack clightd-4.0-Linux.deb ...

FedeDP commented 5 years ago

Mmmh i see now. Clightd package requires ddcutil package, but in your case it was manually installed (thus dpkg does not find it). Ok: instead of installing clightd with cpack -G DEB, just issue a sudo make install and go on to Clight!

FedeDP commented 5 years ago

This entire process would be much simpler if Ubuntu shipped ddcutil together with its own library... :(

That did the trick!

ModDM commented 5 years ago

No problem, you do your best and I appreciate that!

ModDM commented 5 years ago

Oh wow, ddcutil itself provides such packages! See: https://www.ddcutil.com/install/. Please let me know if this works! If it complains that some files are already present (remember your ddcutil/make install), just dpkg --force ddcutil DEB installation!

Ok, if I understand correctly, that is good news. Well, I must confrim that ddcutil is installed successfully and Clightd also, meaning I have to go to Clight now, the last step to make everything work. What would you advise, go to Clight now or make another change to ddcutil, with the fact in mind that that package is installed successfully already?

FedeDP commented 5 years ago

I quickly removed that comment because it seems the package is not working: i was not able to install it. Go on with Clight then!!!

ModDM commented 5 years ago

When I try to install a package required by Clight, I still get the error about Clightd that requires ddcutil and that ddcutil is not installed:

sudo apt-get install libpopt-dev Reading package lists... Done Building dependency tree
Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: clightd : Depends: ddcutil (>= 0.9.5) but it is not installable E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

FedeDP commented 5 years ago

Remove Clightd (sudo apt remove clightd), and re-run sudo make install for Clightd once more. Then go back at Clight and its deps!

ModDM commented 5 years ago

Ok, let´s do that.

ModDM commented 5 years ago

done, but I am no step further with Clight.

ModDM commented 5 years ago

Question about Clight:

cpack -G DEB or sudo make install?

Which do I choose?

ModDM commented 5 years ago

I ask this, because for the other program you said "instead of installing with cpack -G DEB, just issue a sudo make install"

ModDM commented 5 years ago

I tried sudo make install

This resulted in these files, hope it´s right: -- /usr/bin/clight -- /usr/share/dbus-1/services/org.clight.clight.service -- /etc/default/clight.conf -- /etc/xdg/autostart/clight.desktop -- /usr/share/applications/clightc.desktop -- /usr/share/bash-completion/completions/clight -- /usr/share/icons/hicolor/scalable/apps/clight.svg

Further I´d like to update, just for your info and for other users that these packages were needed for Clight:

sudo apt-get install libpopt-dev sudo apt-get install libgsl-dev sudo apt-get install libconfig-dev

Notice the -dev at the end.

ModDM commented 5 years ago

EVERYTHING INSTALLED. RESULT:

After restarting the computer (twice) Clight is installed and runs automatically. (I saw the webcam LED twinkling once).

It has made a bit chaos on my computer, because for big health issues I need radiation to be OFF always. Therefore I have blacklisted Wifi and Bluetooth and since I installed Clight Wifi and Bluetooth modules are loaded on Linux startup and appear in the tray area. I can feel that my health issues come back again and I need to run modprobe for both Wifi and Bluetooth each time I boot the computer. The blacklisted modules in /etc/modprobe.d/blacklist are totally ignored since Clight is installed.

Since Clight is installed I get a warning on my bar that says:

An error occured. Please run Package Manager from the right click menu or apt-get in a terminal to see what is wrong. The error message was 'Error BrokenCount > 0'. This usually means that your installed packages have unmet dependencies.

More details: sudo apt-get check Reading package lists... Done Building dependency tree
Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: clight : Depends: libgsl23 but it is not installable Depends: clightd (>= 4.0) but it is not installable E: Unmet dependencies. Try using -f.

In the meantime I'm interested to know if Clight is working. Brightness: works

But I have the idea that I now have Calise. Clight should be able to do more, like gamma. So I checked this: xgamma -> Red 1.000, Green 1.000, Blue 1.000

This is the default (unchanged) gamma setting, so it seems nothing has changed.

How can I check if Clight actually influenced the color temperature and gamma for example? Are there any values I can verify? Otherwise I even can install Calise, which should work better than this Clight with all dependencies problems.

I am interested in your advise and help.

There is nothing in Clight that forces such a behaviour, and it does not depend upon wifi nor bluetooth.

clight : Depends: libgsl23 but it is not installable Depends: clightd (>= 4.0) but it is not installable E: Unmet dependencies. Try using -f.

I can see libgsl23 on ubuntu packages, may be you're on an older ubuntu version? Btw you should install Clight with sudo make install (or, remove any previously installed Clight package and re-run sudo make install).

How can I check if Clight actually influenced the color temperature and gamma for example? Are there any values I can verify?

You should check $HOME/.clight.log file.

ModDM commented 5 years ago

Since all time all icons / modules concerning connections etc. (except wired connection), that are found in the tray (and tray menu) were not there, because they are always blacklisted explicitely on my computer since the beginning (because I need that for my health > no radiation > I can´t live with 5 minutes of radiation). But I am aware of the fact that other modules / processes easily start blacklisted modules when they need them. If I want to blacklist modules permanently, I need to turn them off in BIOS. But at least strange that since always the tray icons (those modules) were not present, because of the blacklist, and that exactly after finishing this installation process, the tray icons are back again, and not just 1 icon, even multiple at the same time! (Wifi, Bluetooth and Location) They were never there! There should be a relating factor... No, it does not should be, it´s 100% sure it is!

How can I check if Clight actually influenced the color temperature and gamma for example? Are there any values I can verify?

You should check $HOME/.clight.log file.

Thank you, works! But, I meant a direct check outside Clight, to check if Clight is doing its thing. The brightness is working great, but can I check the gamma in terminal once in a time and see it it really changed?

Finally, thank you for all your assistance. It took me more than 1 day to install this program, but I appreciate your help.

ModDM commented 5 years ago

For example: I checked this: xgamma -> Red 1.000, Green 1.000, Blue 1.000

This is the default (unchanged) gamma setting, so it seems nothing has changed.

ModDM commented 5 years ago

I can see libgsl23 on ubuntu packages, may be you're on an older ubuntu version?

Ubuntu 16.04 LTS. I try to install libgsl23, but it has a problem, guess what: a dependency problem with another (non-installable) package / module.

FedeDP commented 5 years ago

quickest way to restart Clight?

Just kill it and restart it!

by the way, any way also to turn Clight off (for the case I don´t know, just to know...).

If you wish to turn anything in clight off, kill it. Btw you can turn off "dimmer" and or "automatic calibration" with a right click on clight desktop file.

ModDM commented 5 years ago

Ok, I will look at it. Is it both a process and a service I need to kill or just 1 process?

ModDM commented 5 years ago

for some reason my comments are posted in 2 issues (#87 and #88), but I assume you did that trick in a setting...
