NVidia graphics issues


Hi All,

I have a CentOS 7 installation on a very new PC (skylake) which does not have drivers for onboard Intel HD graphics. I have put in a Gigabyte NVidia GeForce GT 710 graphics card, however, now the monitor cannot be used as it is just a multi-coloured splash (much like those 3D prints you have to defocus your eyes to see the 3D figures). I have done a lspci -vnn | grep -i vga -A 12 with the following output:

05:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] [1002:68f9] (prog-if 00 [VGA controller])
Subsystem: Gigabyte Technology Co., Ltd Device [1458:227f]
Flags: bus master, fast devsel, latency 0, IRQ 126
Memory at c0000000 (64-bit, prefetchable) [size=256M]
Memory at dfd20000 (64-bit, non-prefetchable) [size=128K]
I/O ports at d000 [size=256]

Kernel driver in use: radeon

lshw -c video returns the following:
*-display
description: VGA compatible controller
product: Cedar [Radeon HD 5000/6000/7350/8350 Series]
vendor: Advanced Micro Devices, Inc. [AMD/ATI]
physical id: 0

resources: irq:126 memory:c0000000-cfffffff memory:dfd20000-dfd3ffff ioport:d000(size=256) memory:dfd00000-dfd1ffff

Kernel version is 3.10.0-327.28.3.el7.x86_64

I have two questions:
1. Why is the Gigabyte NVidia GeForce GT 710 being detected as an AMD Radeon HD 5450?
2. Why is the monitor behaving like described above and how do I fix it?

I actually downloaded drivers for the NVidia GeForce GT 710 and when I ran it, it said that I do not have a graphics card for it. I have then downloaded legacy AMD Radeon drivers, created a symbolic link for version.h, ran it and came up with lots of error while it is compiling firegl version 2.6.x and then stops.

TIA,
Vlad

1002:68f9 is definitely ATI.

Update:

Never mind about question 1. The box lied. The label on the graphics card itself states GV R545 which is a Radeon 5450.

What are the chances CentOS will support your Intel? It would no problem with newer kernel and intel driver.

With the onboard Intel HD graphics, lspci output had no kernel driver. Just like the onboard NIC. I had to put in an old TP-LINK card. In saying that, the monitor was actually usable. This is the same PC that I have been posting questions about with the miss-behaving M.2 SSD. I have replaced the M.2 SSD with a standard 2.5" SATA3 SSD and am trying to figure out if the system freezes may perhaps be due to the onboard graphics missing kernel drivers.

There is no kernel upgrade or at least backport? Weird, what they think people with newer hardware should do.

It'll probably come out in the next release.

Hmm, crashed again over the weekend after running fine for over a week. Replaced the Radeon with an older NVidia GTS 250 but still no luck as there is no kernel driver, and unlike the Radeon, I get no screen, just a blinking cursor at the top left of the monitor (I can still SSH to it etc). Installed ELRepo and NVidia-detect which detected it as kmod-nvidia-340xx. Installed kmod-nvidia-340xx and still no screen.

Never mind. Found the issue in Xorg.0.log:
[ 12.587] (EE) NVIDIA(GPU-0): The NVIDIA GPU at PCI:5:0:0 does not have the necessary
