[DONE]Upgrade from 6 to 7 couse black screen

[doktor5000]

In ver M6 there was Nvidia driver in kernel. After upgrade to M7 it disappear. Looking to the desktop PC equipped only in Nvidia (without Intel) such packages are present:
[...]
How do You think. Can I simply install above packages?

You basically answered your question yourself already, no ?

OK, Nvidia packages installed but can not load Nvidia module. See below:

11M     /lib/modules/5.1.14-desktop-1.mga7/dkms/drivers/char/drm/nvidia-current.ko.xz

And there is no definitions in xorg.cof related to Nvidia.

Any idea what to do?

It's pretty obvious, no? There's no such module, so the error is correct. It's either nvidia340 or nvidia-current.

Still does not work. New kernel (just released today):

Reading viewtopic.php?f=23&t=12934#p75844, your problem might be that you have both nvidia340 and nvidia-current installed. Try removing the one you don't need.

Do you know what caused both to be installed?

[mackowiakp]

Yes, I have both installed. Where was both drivers installed in M6 too. Each kernel or Nvidia driver update of M6, caused re-linking the kernel. In M6 it worked like a charm. Especially with Dassault Systèmes 3D CAD system, using Nvidia CUDA. Now it work only using on-processor Intel GPU so CAD app does not has such performance as it has under M6. This error occurs only when I try to load Nvidia library. The driver is already present in kernel. I have to mention once more. There is no two separate graphic cards. It is kind of "combo" card. And I need both drivers. The hardware is laptop ASUS G551J, 4 core 8 thread CPU, 32 GB RAM, M2 type SSD HDD 256 GB and 1 TB "ordinary" HDD.
BTW. It work properly under WIN10, but the performance under M6 (with Nvidia driver working) was much better.

[martinw]

So have you tried removing the unnecessary driver, as discussed in the thread I referenced?
Just to be clear, nvidia340 is an old version of the nvidia proprietary driver that only supports older NVIDIA cards. nvidia-current is the latest version of the nvidia proprietary driver that only supports recent NVIDIA cards. You only need the one that supports your card.

[mackowiakp]

Every Nvidia modules I have installed, are relayed tu driver version 3.40, including nvidia-current:

Code: Select all

[root@piotr-l ~]# rpm -qa|grep nvidia

nvidia-current-doc-html-430.26-1.mga7.nonfree
dkms-nvidia-current-430.26-1.mga7.nonfree

This output above is taken from laptop equipped with "combo" Intel/Nvidia card. And it cause error:

Code: Select all

[root@piotr-l ~]# modprobe nvidia-current
modprobe: ERROR: could not insert 'nvidia_current': Cannot allocate memory

As I wrote, it worked properly in M6.
Below output from desktop PC equipped only in Nvidia card:

Code: Select all

[root@Piotr Pobrane]# rpm -qa |grep nvidia

x11-driver-video-nvidia340-340.107-9.mga7.nonfree
nvidia-current-devel-430.26-1.mga7.nonfree

And it works properly in M7. As You can see, both outputs are identical. So what the problem is?

Because black screen after reboot is DONE, so I create separate topic about INTEL.NVIDIA combo card problem. So close this topic
