http://ubuntuforums.org – Hi everyone, I'm not sure this is the right forum. I am running the newest version of Ubuntu (12.04 LTS). I have 2 video cards that I am using that I would like to use to power my 2 displays, so that both monitors can be run on DVI. The first card is my primary card and is an ATI/AMD Radeon 4850 that is in a 16x PCIe slot. The second is a low-end NVIDIA PCI card. I believe that this setup worked with no issue with a previous version of Ubuntu, but that was a few years ago. I have tried different permutations of the restricted drivers, but have not been able to get it to work. The second (Hardware)

Stories similar to [ubuntu] Dual video card/dual display issue

I am new to Ubuntu 12.04. A month or so ago I had ATI Radeon video card with plugs for two displays, and Ubuntu showd desktop on both. Then I switched to Nvidia GeForce GTX 680, also dual-display cable. But now it only diplays on one monitor. I made sure cable connections are tight; I know they're good cables because they worked with ATI card.

Any ideas how to get my dual displays back?

Does the onboard video on the motherboard affect the X windows configuration?

My system has onboard and pcie video. The onboard video is a NVIDIA GeForce 7025 GPU, On Board Graphic Max. Memory Share Up to 512MB(Under OS By Turbo Cache). I have a pcie dual head video card installed with two monitors. The video card is a GeForce 8400 GS, with 512mb memory.

I had a spare machine running vista.I have removed vist and from CD installed ubuntu. It all works ok except for my dual screens. I want the dual screens so I can read instructions and try things on other screen I have a "radeon hd4650 1gb ddr2 v/d hdmi" video card am very confused regarding setting up the video card. Is there a radeon card setup site that is good for a newbie :D

I want to install a video card into a server. When it is inserted, server does not boot up and there is no video signal coming from video card. 4 LEDs at the back of the motherboard show pattern G-R-R-A which means "Disabling the console controller" (see Appendix C in manual). There was another (older) video card in that PCI slot and it worked fine.

I have a PC that has an integrated graphics chip on the motherboard. It runs X nicely. I bought a video card (NVIDIA GEFORCE FX5200), installed it in a PCI slot, downloaded the drivers from the nvidia website, installed them, rebooted, connected the monitor to the new video card, and that worked fine.

I recently moved to 9.10 and have lost the ability to run a dual monitor arrangement with my ageing Matrox G550. After searching the various forums, it seems that if I want to use more than one monitor I need a new video card. Fine.

Another issue with Ubuntu 12.10: I have an USB DVB Avermedia card In 12.04, and all previous versions I remember since 10.x worked with this hardware enabling its driver in "restricted drivers".

Now I discovered that I cannot even enable the card, any idea?

Thanks

I just got given an ATI Radion Saphire HD 3650 card.

hi, I'm fairly new at Ubuntu and Linux in general. With that said, I have been patient enough and resourceful enough to find most of my questions already answered by googling it or looking here. Right now I have been looking for days on a way to do this and i have found no successful answer.

I am using Ubuntu Jaunty 9.04 with the most current updates init
