Hi there.

I've a desktop environment with dual monitor attached to linux box (slackware 14.1 64bit, xorg, nvidia).

This morning I turned on my box and both the screens were blank.
No video output. No welcoming bios, no boot wall of text. :-/

I can ssh to the desktop and to me seems all work well, but the monitor stay blank.

I suspect strongly the graphic card is burned, but don't know if there is any check sw side I can do before to buy another one.

Any hints?

* From syslog/lsmod I see the nvidia modules are loaded.
* No video output from mobo, unfortunately.

Hi...

If this is a add-on card, try reseating it. If you can, check your PSU with a power supply tester.

Also, apart from the graphics, does it boot normally in every other way, including the short, single beep?

Regards...

Thanks for advices, but i don't know how check psu indeed. :-/
Yes, a part graphics, it boot normally and all goes smooth.

After a bit of tinkering, I found an old geforce 210 that help me to restart the graphic system - so I'm decided to buy a new video card with no doubts.

Hi...

When you get your new card, let us know how it works.

If you feel your issue is resolved, please mark this thread as "SOLVED" by clicking on "Thread Tools" directly above your initial post. Thanks!

Regards...

I bought a AMD/ATI Sapphire R9 280 (Tahiti PRO, Radeon HD 7950).
At the moment I tryed it with default linux radeon firmware (OpenGL software rasterizer) and with proprietary drivers and it works very well.
I still have to try the open source 3d drivers. :-/

K.

However if someone in future want point me how to understand software/os-side when the video card is burned, I'll read with pleasure.

Hi...

Glad to hear your new card is working fine but if the proprietary driver are working without any problems, I would stick with that, as the fglrx driver (proprietary,) I think, offers better functionality and quality overall than the open source driver.

How do you mean exactly? What are you wanting to know?

Regards...

I was wondering if exist a way to understand the graphic card is burned querying the os.

Example: I checked lspci but it showed a pretty right VGA entry also if the card was out.

Hi...

Perhaps one method is doing a stress test on the GPU with software such as this. I've not used this particular program so I can't vouch for it but there may be others.

Regards...
