Can't get a DVI monitor working with openSUSE

English Hardware
1

Hi all,
I’m trying to get a DVI monitor (NCR) working with a small pc (NCR 7600-2000-8801) that’s a POS system. I need to get it working with any SUSE version. I tried with openSUSE 15.1 and it didn’t detect the monitor. I was curious if Ubuntu could detect it, but it didn’t. The system also has a VGA monitor connected, and it works, so I could boot with it, but it won’t detect the DVI monitor later. The DVI monitor works with Windows, I mean, it’s ok.

It looks like there isn’t much information on the drivers for linux for this system.

1.- lspci doesn’t show anything regarding the DVI monitor, it just says it’s an atom processor:

2.- ‘hwinfo –-gfxcard’ shows the VGA port only:

3.- I think the default kernel comes for an Intel processor, but this one is Intel Atom:

Should I compile the kernel for Atom? I didn’t find is there is a parameter to load, or module to load, or support to add to the kernel, to get the DVI monitor detected.

Any idea about how to deal with it, please?

Many regards,
Luis.

Hi and welcome to the Forum :slight_smile:
Your device uses the gma500_gfx driver;


/sbin/modinfo gma500_gfx | grep 0BE2
alias:          pci:v00008086d00000BE2sv*sd*bc*sc*i*

Is this module loaded?


lsmod | grep gma500_gfx

If not, run as root user;


modprobe gma500_gfx

Does this help?

Hi
Also in the system BIOS, is there an option to configure the display output(s)?

Cedarview has GMA 3600/3650 graphics - this is a piece of **** (my post was automatically censored - what a …).
If you have ability to put in discrete graphics card - do it.
And then disable internal graphics.

Hi,

There is an item called “North Bridge Configuration”. A sub item says “Primary Display Selection”, I tried Auto and didn’t work. I can boot, but no GUI is started. Other options are IGD, PEG, PCI.
Also, there is an item called DMI ASPM, it’s set to Enabled.
For IGD Configuration item, options for IGD Boot Type are VBIOS default, CRT, LFP, EFP, LEP+EFP, CRT+LFP, CRT+EFP.
Options for IGD Panel Scaling are Auto, Force Scaling, off, and Mantain aspect radio.

Any idea about what would be worth to try, please?

Thanks!

Luis.

Hi
So how are the monitor(s) connected, vga, dvi (is it DVI-D or DVI-I)… I would try the CRT+EFP or CRT+LFP, Does it have an onboard connect for an LVDS screen?

Hi, I’m afraid your system reminds me the netbook I had. It does not have intel graphics card, but actually somehow outsourced power VR card, which had closed source drivers only for ubuntu 12.04, tied to certain kernel version and X version. It does not even have drivers for windows 10(!), it had drivers only for windows 7. I wish you best of luck, but I’m afraid, that Mr. Svyatko is right, the integrated card in this CPU worths his censored words.

Since he has VGA working - I would get a VGA to DVI adapter and go from there.

Newegg has them ( make sure it is VGA to DVI and not the other way)

Sometimes more hardware is the answer to a software problem.

It is much easier to find monitor with VGA input.

For OP: https://wiki.archlinux.org/index.php/Intel_GMA_3600
No acceleration.

If you will go the adapter way, make sure your monitor can accept analog DVI, if it’s digital only, cheap adapters without A/D chip won’t work.
