Monitor not detect

[almondon]

Thanks @jlehtone

yes, I have some sort of screen and have access to keyboard, I think I do not need ssh.

Just by trying to install kmod-nvidia in el7 I receive error as I explained in previous comment.

[jlehtone]

I tried as root and I received this:
Error: nvidia-x11-drv conflicts with ocl-icd-2.2.12-1.el7.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

The ocl-icd is from EPEL and provides:

Code: Select all

repoquery --provides ocl-icd
libOpenCL.so.1()(64bit)
libOpenCL.so.1(OPENCL_1.0)(64bit)
libOpenCL.so.1(OPENCL_1.1)(64bit)
libOpenCL.so.1(OPENCL_1.2)(64bit)
libOpenCL.so.1(OPENCL_2.0)(64bit)
libOpenCL.so.1(OPENCL_2.1)(64bit)
libOpenCL.so.1(OPENCL_2.2)(64bit)
ocl-icd = 2.2.12-1.el7
ocl-icd(x86-64) = 2.2.12-1.el7

The nvidia-x11-drv-libs from ELRepo provides (among other things):

Code: Select all

libOpenCL.so.1
libOpenCL.so.1(OPENCL_1.0)
libOpenCL.so.1(OPENCL_1.1)
libOpenCL.so.1(OPENCL_1.2)
libOpenCL.so.1(OPENCL_2.0)
libOpenCL.so.1(OPENCL_2.1)
libOpenCL.so.1(OPENCL_2.2)
libOpenCL.so.1(OPENCL_3.0)

Two packages provide the same feature. Only one can be installed.


Uninstall the ocl-icd (and pay attention to what goes with it). Then install the NVidia drivers.

Thanks for your reply,

yes, I think removing elrepo might be risky.
(Also, I'm not sure if after removing elrepo I can work with nvidia-detect and then 'yum install kmod-nvidia')

I tried before and I think the following packages would be removed:
sudo yum remove ocl-icd

Oh yes. Both ELRepo and RPMFusion do actually provide NVidia drivers. I have always used ELRepo version.

You have installed VLC from RPMFusion. It needs something. At the time of installation
that something was available only in EPEL package ocl-icd, so you now have that
and it blocks the installation of NVidia driver.

Your system can live a moment without VLC and ffmpeg.
The sudo yum remove ocl-icd is thus ok. You can sudo yum install vlc later.

When you do have removed the ocl-icd, you can:
sudo yum install kmod-nvidia
and after that install the VLC back.

Thanks @jlehtone for your message and the explanations.
I will try to remove it and will try to
sudo yum install kmod-nvidia

and will try to report the process here.

Cheers

[almondon]

Thanks @TrevorH @jlehtone for your helps.
I removed ocl-icd and installed kmod-nvidia successfully.
Now I have monitor with full resolution on my pc.

Just I have several kernels and I think make the boot drive full.
Can I remove them and keep only the last one or the last 2 one.

Cheers

[jlehtone]

Can I remove them and keep only the last one or the last 2 one.

Yes. Package 'yum-utils' has utility 'package-cleanup' that can be used:

Code: Select all

sudo package-cleanup --oldkernels

It does actually call yum, so you get to [y/N] what it would remove.

See man package-cleanup for what else it can do.

Thanks @jlehtone for your helps and sorry always for being late.
