BadRRCrtc (invalid Crtc parameter)

[PavelTurk]

OS - ubuntu 24.04

I installed new version of xcalib this way:

sudo apt-get install libx11-dev libxrandr-dev  libxss-dev libxxf86vm-dev libxkbfile-dev libxv-dev 
git clone https://github.com/OpenICC/xcalib.git
cd xcalib
cmake CMakeLists.txt
sudo make install

and this is what I have:

pavel@notebook:~$ xcalib --version
xcalib v0.11.0 - Tiny monitor calibration loader for Xorg and Windows.

For more information read the man page:
	man xcalib

pavel@notebook:~$ xcalib -co 70 -a
X Error of failed request:  BadRRCrtc (invalid Crtc parameter)

Could anyone help me?

The UI changed from version 0.10 to 0.11. Please see: xcalib -h # or xcalib -hv for more infos.

@beku Thank you for your answer. I've read help and this is my command to set contrast:

pavel@notebook:~$ xcalib -k 50
Client Canceled:  xcalib.c:1199 myMain() Unable to read file "----"

Could anyone help to fix it? My display is killing my eyes.

Synopsis: xcalib -g=NUMBER -b=NUMBER -k=NUMBER -d=STRING -s=NUMBER [-o=NUMBER] [-v] [-n] [-p[=FORMAT]] [-l] ICC_FILE_NAME | -a Please consider the last both options, which say ICC_FILE_NAME or ('|') -a Option. That makes sense with the error message you obtain. My recommendation, if you have no ICC profile use -a. Am 30.04.24 um 20:09 schrieb PavelTurk:

@beku Thank you very much for your help and explanation.

What I have now - in Settings/Color I selected xcalib gamma 2 profile and it decreased color darkness what was my problem. Now I want to adjust it a little bit. For this I used the following command:

root@notebook:/usr/local/share/color/icc/xcalib/test# stat -c '%y' gamma_2_2.icc 
2024-04-30 08:45:49.000000000 +0300
root@notebook:/usr/local/share/color/icc/xcalib/test# xcalib -k 50 ICC_FILE_NAME gamma_2_2.icc 
root@notebook:/usr/local/share/color/icc/xcalib/test# stat -c '%y' gamma_2_2.icc 
2024-04-30 08:45:49.000000000 +0300

However I don't see any changes and file was not updated. I tried to do it also as non root user:

pavel@notebook:/usr/local/share/color/icc/xcalib/test$ xcalib -k 100 ICC_FILE_NAME ./gamma_2_2.icc
pavel@notebook:/usr/local/share/color/icc/xcalib/test$ 

But it didn't help either. I don't see any changes on any xcalib command. Must it modify icc file? Should I restart after every commands? Why does it not work?
