Hi,

If VMware is a must the mainline kernel should work if you use bumblebee?  You 
might have to go into runlevel 3, remove all of nouveau, set your default boot 
to runlevel 3, reboot, install the mainline kernel, then follow the bumblebee 
wiki to get nvidia working with the mainline kernel.  Then startx and check 
your Xorg log file for errors and if it works hopefully VMware will work.  I 
don't know if this will make a difference but have you tried Oracle's 
VirtualBox?  It might have better support for Linux.

Suggestion: set it to runlevel 3. After it comes up in text mode, try
startx, and see if that tells you more. Also, you won't have to reboot

Have you looked at /etc/X11? Or tried the nVidia configurator?

Hello,

I yum-removed xorg-x11-drv-nouveau, but system will still hang after
gfx login.

After I log in, the mouse is shown on the grey wallpaper, and nothing more.
If I attempt to switch to a text tty: mouse is gone, same wallpaper, and no
more control on mouse or keyboard, this looks like a video/Xorg issue.
Xorg.log shows that it loads the Intel module but still looks for the nouveau 
one:

[ 6.565] (II) LoadModule: "nouveau"
[ 6.565] (WW) Warning, couldn't open module nouveau
[ 6.565] (II) UnloadModule: "nouveau"
[ 6.565] (II) Unloading nouveau
[ 6.565] (EE) Failed to load module "nouveau" (module does not exist, 0)

Second attempt: blacklisted nouveau kernel module -> nouveau still
shows in `lsmod` after reboot (w/ a non-ml kernel), wft? But Xorg.log
doesn't mention nouveau anymore, success? No, it still hangs w/ ml
kernel.



After all this, I wanted to get back to kernel 3.10, to see now that
nouveau is off, if that changes something. Well this is a surprise,
everything works fine w/ this 3.10.0-514.26.2.el7.x86_64 kernel
(suspend/hibernate/wifi/hmdi-out/dell keys/vmware) BUT the bluetooth
(and the dell fn+radioswitch key).

I re-installed drv-nouveau, removed the blacklist file
from /etc/modprobe.d and all is still OK, but Xorg doesn't loads
nouveau driver despite the fact that lsmod shows the nouveau kernel
module (I checked, during my former attempts w/ this 3.10 kernels, it
was already the case: Xorg not loading drv nouveau).

IOW this whole topics turns into something more complex (call that a
mess?) ;-) and I don't understand how it could not work w/ regard to
these laptop features and how it works now.

I'm willing to help w/ the experimental or ML 4.x series kernels, but
in terms of personal productivity, I will also focus on solving the
bluetooth issue w/ 3.10 kernel.

This point can be done. First to verify that the intel gpu is work.

I got old laptops in my office and disable nvidia at first and it
works.

Secondary. If the offical NVIDIA kmod version works with the rest of
his hardware he can go on with bumblebee. NVIDIA drivers disable
nouveau in the same way as I tell him.

In that time, no, but since then, yes. I replied some detail elsewhere

You want to look into Bumblebee for this hybrid nvidia setup.

The Intel HD GPU is actually integrated on the CPU die; the discrete
graphics adapter usually has higher performance for graphics-intensive
applications. 

In windows, you should be able to choose which graphics adapter an
application uses by right-clicking its shortcut and choosing the "Run with
graphics processor" option from the context menu (the default can also be
set in the NVIDIA Control Panel, with NVIDIA adapters). So you can have the
integrated GPU handling mostly static displays and using less battery, while
the dedicated GPU kicks in for AutoCAD, video editing, gaming, et cetera. 

On desktop PCs, if the display/s is/are connected to the discrete GPU's
output port/s then the discrete GPU is used for everything.

I don't know how to tell which graphics adapter is being used by a
particular app in CentOS... the only benchmarking suite I've heard of for
CentOS is Phoronix (look in EPEL), which should have the GLMark2 benchmark
to test the OpenGL renderers. I'm not aware of any linux flavor that
supports Direct3D.

I'll try disabling nouveau as soon as I can and let you know, but also
try the opensource version from nvidia. Thanks for both suggestions!

Ok you in Grub press tab and then add „3“ after the initrd entry …. quiet…“

yum remove xorg-x11-drv-nouveau

And see if X11 come up with standard frambuffer…

Disable nouveau complete from kernel if the upper not helps.

nano /etc/modprobe.d/blacklist-nouveau.conf

blacklist nouveau

It didn't. I tried to boot using kernel-ml-4.12.4-1.el7.elrepo.x86_64
but it hangs either before or right after the graphical login. No
visual tip, system is not responsive until I shutdown the computer.

What about now that you have it booted and working except for VMWare install 
the mainline 4.x kernel that is available?  Take precautionary steps to make 
sure that will work, hence, back up any data and, if need be, configs.

Would that work?

Just as a point of information, CentOS 6 runs on a Knights Landing
architecture, though 7.x makes more features available. And that was about
a year ago

CentOS7 has a kernel which is simply not modern, unable to handle lots
of computers sold currently.

That said, there might be a way to boot, but nothing trivial and
nothing at all I could find on the Internet, everytime it's kernel
4.3/4.10 minimum required.

...

While I know that Johnny has provided the experimental kernel (thanks,
Johnny) I would like to just briefly address this idea that the C7
kernel is 'obviously' not going to work because 'is 3.x and must have 4.x.'

In EL-land, kernel versions are effectively meaningless, since features,
hardware support, bugfixes, security fixes, etc are back-ported into the
'old and not modern' 3.10 kernel (for EL7) by competent developers at
Red Hat.  An EL 3.10 kernel, such as the current
3.10.0-514.26.2.el7.x86_64 one, may have hardware support back-ported
from a 4.x kernel that doesn't exist in the vanilla kernel.org kernel
(I'm almost certain it does, but I'm not going to take the time to get
details).



It might work in the RHEL 7.4 kernel .. I'll get that onto buildlogs for
testing while I am working on the CentOS Linux 7 upgrade builds.

And yes, people do need to understand that Red Hat backports newer
firmware and drivers to the older kernels.  There are plenty of 4.x
kernel things backported.  So, as you correctly pointed out, you can't
treat the Red Hat 3.10.x kernels like kernel.org 3.10.x kernels.





Indeed, Lamar and Johnny are correct. For example, the wireless driver 
stack from kernel-4.11 has just showed up in the RHEL-7.4 kernel 
released yesterday.


Further, I would encourage anyone to file RFEs upstream with Red Hat for 
support to be added for any currently unsupported hardware. If Red Hat 
don't know you want support for it, it won't get added. If you don't 
ask, you won't get.


Whilst you are waiting on Red Hat to backport support into the distro 
kernel, don't forget elrepo.org also specialise in backporting 
individual device drivers which can provide an invaluable stopgap 
allowing the distro kernel to continue to be used until such time as the 
hardware is natively supported. For example, I recently built an updated 
i2c-i801 el7 driver adding backported support from kernel-4.4 for 
Braswell and Wildcat Point ICH's following an RFE from a user.

Thanks for this clear explanation, Lamar. I'll surely keep an eye on
further kernel updates (and CentOS 7.4).

CentOS7 has a kernel which is simply not modern, unable to handle lots
of computers sold currently.

That said, there might be a way to boot, but nothing trivial and
nothing at all I could find on the Internet, everytime it's kernel
4.3/4.10 minimum required.

...

While I know that Johnny has provided the experimental kernel (thanks, 
Johnny) I would like to just briefly address this idea that the C7 
kernel is 'obviously' not going to work because 'is 3.x and must have 4.x.'


In EL-land, kernel versions are effectively meaningless, since features, 
hardware support, bugfixes, security fixes, etc are back-ported into the 
'old and not modern' 3.10 kernel (for EL7) by competent developers at 
Red Hat.  An EL 3.10 kernel, such as the current 
3.10.0-514.26.2.el7.x86_64 one, may have hardware support back-ported 
from a 4.x kernel that doesn't exist in the vanilla kernel.org kernel 
(I'm almost certain it does, but I'm not going to take the time to get 
details).


So it is very possible that full hardware support for your hardware 
could show up in a 3.10 kernel (in fact, I would expect that this would 
happen, but it might not happen quickly).  As you found out, 
experimental kernels and non-distribution kernels can freak out software 
packages, such as VMware Workstation, that only work with certain 
kernels and are expecting a particular kernel version and ABI for EL7.  
I've tried out a few non-standard kernels before, and if you rely on 
packages that depend upon the distribution default kernel version (as I 
do with kmod-nvidia from ELrepo!) that breakage can be swift, and can 
derail you in a hurry, causing you to go down a rabbit hole very 
quickly.  So be prepared and keep your eyes open for these issues.


In some circles, the back-porting of features into old kernels is 
controversial; but that is a business decision made as part of the EL 
development and is not likely to change any time soon.  YMMV.

In addition to my previous reply:
 - suspend works
 - hibernate works
This is just great!

But it fails to configure VMWare Workstation 12.5.7 and this is a must
for my pro activities on this machine.

The build of vmmon and vmnet kernel modules fail. The 12.5.7 version
contain the fixes for known/recent issues related to installing VMWare
WS on 4.6/4.9 kernels (API changes) and I couldn't find a tip about how
to solve this yet. Probably off-topic here, but I doubt I'll get
support from VMWare since it's an experimental kernel on top of CentOS7.

I am using this experimental kernel on my workstation (lenovo w541). I
have been using it for quite a long time and have not had any major issues.

I also use it on my secondary workstation (lenovo h50-55).

I could boot 4.9.39, it brings:
 - Dell features like screen light control and wireless toggle key,
 - dual screen support using the HDMI port,
and maybe more that I couldn't see, wow!

 Hello there,


 I've just got a Dell XPS 15 (9590) at work and need to set up a stable
 GNU/Linux system on it. I thought of CentOS7, but.. obviously its
 kernel can't run on this hardware.

 What would you recommend? Waiting for CentOS8 is not an option unless
 it's a question of few weeks. Are there respins of the CentOS7 DVDs w/
 more top-recent kernels? I'm know of Fedora 26 or course, and not
 willing to switch to Ubuntu 16.10 at all.

There are actually 2 kernels, one on the live DVD I just posted, and one
in the experimental repo.

Both of those would require NO secure boot turned on, but they both
should work fine with UEFI and secure boot off.

I've just succeeded in installing CentOS7 from the DVD! Had no luck
using a Live CD (both dd'ed to a flash drive).

Hardware support is not complete (or not configured as-is):
 - bluetooth not working
 - HDMI ouput -> nothing
 - dell Fn keys -> no screen light, no wifi toggle
 - no suspend/hibernate

I will now try to inject more recent kernels (yours *) or extra firmware,
see how I can find better hardware support and configuration. And
compare this to what Fedora 26 provides..

(*) BTW, I installed your 4.9.39 kernel (did a yum update after
configuring a repo file to get your stuff) and at boot, I immediately
get:
error: $KERNEL_NAME_HERE has invalid signature
error: you need to load the kernel first

OK .. I just pushed this ISO to the master mirror:

CentOS-7-x86_64-LiveGnome-1707-exp.iso (sha256sum):
f60d806f513f337acd09c5cf4a2ec3c735ba82519798d07096992916fc4cf271

Once it makes it to the mirrors, it can be downloaded via this link:

https://buildlogs.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-LiveGnome-1707-exp.iso

I also tested this on a physical machine (t520 thinkpad) , as well as an
install on a KVM VM, and it installs fine both places.

After install and reboot, add in the experimental.repo file via this
link (bottom of the page):

https://wiki.centos.org/SpecialInterestGroup/AltArch/i386

Run a 'yum upgrade', reboot and you should be set.

Thanks,
Johnny Hughes

 4.9 kernel tree for CentOS-7 that is.

 It lives here:

 http://mirror.centos.org/altarch/7/experimental/x86_64/

 (currently pushing a 4.9.39 kernel there)

Once I get a working ISO that installs, I'll post a link.

You would have to set up the experimental repo in /etc/yum.repos.d/ to
get kernel updates, and those would be RPM only.

In fact, I have a live ISO now that installs (in KVM) .. but I still
need to make sure this kernel updates correctly from the experimental
repo.

The kernel (and linux-firmware) rpms are unsigned, but should upgrade
from the experimental repo for future upgrades and those are signed.

So, I should have something installable sometime in the next few hours
that you can try.

Johnny Hughes

Where could I get an ISO (once fixed), I only saw RPMs at the link you
pasted? Or do I have to assemble myself in some way?

 I've just got a Dell XPS 15 (9590) at work and need to set up a stable
 GNU/Linux system on it. I thought of CentOS7, but.. obviously its
 kernel can't run on this hardware.

 What would you recommend? Waiting for CentOS8 is not an option unless
 it's a question of few weeks. Are there respins of the CentOS7 DVDs w/
 more top-recent kernels? I'm know of Fedora 26 or course, and not

Thanks!

I read that elsewhere, that's what I did too.

I could install F26 and run it, that will probably be my option if I
definitely fail w/ CentOS7+whatever and once I solved the UEFI config
issue (Windows overrides it everytime).

I'll probably use a WD15 Dock, apparently that works out of the box in
Linux too, provided that the dock firmware is up-to-date.

As a try, I could install a Fedora 26 - installation and runtime went fine,
apparently for everything (cpu, disk, video, wifi, bluetooth, sound..).
Bad luck, once back to Windows (it's a dual boot), the UEFI config lost
the F26 entry, I'm good to reinstall and find how to prevent Windows to
override the UEFI config. Also digging other directions..

This is why I appreciate KDE neon (https://neon.kde.org/) as a "lesser
evil" fallback solution on hardware that does not support CentOS. Its
base is LTS, hardware support is improved between minor releases. The
system is stable (e. g. usable), and its support is way longer than Fedora.

Can you boot the installation DVD? Does the installer come up? If not,
can you use the text-mode installer?

4.9 kernel tree for CentOS-7 that is.

It lives here:

http://mirror.centos.org/altarch/7/experimental/x86_64/

(currently pushing a 4.9.39 kernel there)

Re: [CentOS] What RH-like on a Dell XPS 15 (9590)?

[Kahlil Hodgson]

I have a Dell XPS 13 (9360) with Fedora 26 installed. Very happy with it.

UEFI boot from flash drive works out of the box.

For install I needed to change the drive settings in the BIOS from the
default of RAID (what ever that means on a laptop) to AHCI. No need to
turn off secure boot.

If you want to use a DisplayLink USB display adaptor like the D3100
(commonly sold with this laptop), you might want to checkout
https://github.com/displaylink-rpm. This will require either you to
turn off secure boot or to sign the displaylink modules after they are
installed. Signing is not that hard, but is a extra step that you have
to look after.

Kal

And, if Ubuntu isn't pariah, even it's LTS has a reasonably current kernel.  
However, the "Debian way" (Debian, Ubuntu, others) is enough different than the 
"Red Hat way" (RHEL, CentOS, SuSE more or less) that, if it's important to you, 
stick with the RPM-based options.

I would go with Fedora or OpenSUSE latest if you want RH like on that
hardware. There is nothing that unstable about them other than losing
updates and maintenance after 2 years and having to upgrade.

Another choice is to run Virtualbox on the Windows that shipped with the

If you REALLY need RHEL (CentOS) running on the hardware I would return

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7-Beta/html/7.4_Release_Notes/new_features_hardware_enablement.html
 



Well, the only thing that catches my eye here is the support for newer Intel 
PCHs.

Skylake (Purley) servers exist, so I would assume that RHEL would need to 
support these chipsets.

Wireless, GPUs etc - that’s something different.


Of course, there’s always SLES (or SLED, in the OPs case), which has a somewhat 
more recent kernel, AFAIK - if we’re playing „Anything but Ubuntu“.
;-)

The above beta came out in May. So I’d hazard a guess and say it’ll be late 
autumn before we see a release and I’d hope for a pre-christmas CentOS 7.4 
release….

I recommend using Fedora Media Writer 
https://github.com/MartinBriza/MediaWriter/releases over unetbootin;
our QA team reports that unetbootin just isn't guaranteed to do the
right thing.

Right, I'm currently digging that way, struggling a bit w/ the way I
write the F26 ISO to a USB flashdrive (I'll succeed tomorrow, found
better howtos to get rid of unetbootin issues).

Fedora could be stable enough even if not a standard/reference in

CentOS because it is way more compliant to my "corporate" needs (LTS),
but a Fedora could be do it, if it really does it, at least until

I would first ask kindly: please, do not to post.

I would second that. Namely, I had quite a few Dell laptops, all of them
that were configured and purchased from Dell as Linux laptops (Dell
installs  latest Ubintu on them), were easily reinstalled with latest
CentOS, and I never had trouble doing that.

To OP: Once you do clean fresh installation of latest CentOS 7, and update
everything, please, report problems you have encountered. This list has
greatest experts: I know, I got help here multiple times.

Good luck!

It is as simple as unknown hardware at boot up, it's a well known issue
w/ *Lake hardware (modern hardware) that kernel 3.x cannot handle.
CentOS7 has a kernel which is simply not modern, unable to handle lots
of computers sold currently.

That said, there might be a way to boot, but nothing trivial and
nothing at all I could find on the Internet, everytime it's kernel
4.3/4.10 minimum required.

In that case — and I freely admit I have some bias here — I highly
recommend Fedora. It's not stable in the sense of strict ABI
compliance, although we try to minimize disruption within the 13-month
life of a release, but it is stable in the "does not crash" sense.

Hey, I just tried googling, and I cannot find a 9590, only 9550. You sure
of that?

Oh, and will it boot without UEFI from a flash drive?

It's a good question. When I wrote that, I was wondering what do I mean
saying "stable". Provided that it could be a top-recent kernel or a
respin, I guess that the stable concept is potentially gone.

Say, instead of stable, something not rawhide. But I'll examine all
options that do work, so let's forget about "stable".

What sense of the word "stable" are you looking for?

I would like to do that, but the live CD doesn't even boot, unknown
hardware and that's the point. I thought I could find a respin of the
DVD or Live CD w/ a recent kernel in.

Usually, I install CentOS 7 with KDE on all desktop computers, mine and
those of my clients. This is my "standard" desktop installation.

https://blog.microlinux.fr/poste-de-travail-centos-7/

On more recent hardware, I usually try to run a kernel from ELRepo,
either kernel-lt or kernel-ml. One the repo is configured:

# yum --enablerepo=elrepo-kernel install kernel-{lt,ml}

I everything else fails (which happened recently on some weird el cheapo
laptop from a friend), I'll install KDE neon, which is a healthy mix of
bleeding edge and stable. This is a "least evil" solution, but it
actually works nicely.
