1. Quadro Nvs 450
2. Quadro Nvs 290

I have a Dell Optiplex GX520 running Ubuntu. It was working perfectly until I installed a new graphics card. The Nvidia Quadro NVS 280.

After I installed it in my pc It wouldn't boot up it just kept restarting. I think the driver I needed was Nvidia-96 but I'm not sure I couldn't get it to install anyway just kept saying I've held broken packages and no matter what I tried I couldn't fix it. I tried Synaptic to try get rid of the broken packages and nothing, I tried using -f command in terminal and nothing.

The live CD wouldn't boot either just kept making my pc restart. I could get it to boot if I went into the recovery mode and then just asked it to boot normally but I couldn't get it to realise that the graphics card is dual screen and it just displayed the desktop on both screens. I tried the card with an older version of Ubuntu 10.10 and it worked perfectly, booted up just fine, recognised the dual screen output but 10.10 is no longer supported How can I get the graphics card to work in 12.04? Any help at all would be a great help I've been sat here for days trying to figure this out and I'm all out of ideas. I read something about a feature in Ubuntu 11 that causes issues but I don't know if that applies here. Last edited by.FuSeD.; March 10th, 2014 at 04:45 PM. I have this exact same problem.

Optiplex GX520 with a PCI Nvidia NVS 280. Infinite boot loop. I can get in with nomodeset but the nouveau drivers seem to just crap out and cause boot loop or something. I forced install of nvidia drivers 331.49 (which according to nvidia.com fully support the NVS280) but it gives me artifacts all over the screen. I am going to try a couple of different distros to see if I can get one to work. I already tried ubu 13.10, mint 16, mint debian, and even puppy linux and all cause boot loop except puppy which just says 'boot error' and freezes. I think tomorrow the final beta for 14.04 comes out so I guess I'll give that a shot.

I'm not sure if maybe there is a conflict with the built-in intel graphics which cannot be disabled unless a pci-e x1 card is inserted (according to the bios). If it comes down to it i'll grab a pci-e x1 card off of ebay and see what happens. Update: here are the following distros I tried Ubuntu 14.04 final beta live CD - boot loop. Can get in with nomodeset. Tried installing proprietary nvidia driver during live CD from the 'Additional Drivers' menu which for some reason recommended nvidia-173 (version 173.14.39) even though nvidia.com recommends 331.49.

Anyway it didn't work. It was stuck in software rendering mode regardless of what I did. Mint 16 (based on 13.04 I think) cinnamon - boot loop. Same as above. Tried newest nouveau from xorg-edgers, and also tried nvidia-331 (331.49). Corrupted screen and turned off second monitor as soon as I installed it. Mint Debian - same as Mint 16 Puppylinux - won't even boot live CD.

Says 'boot error' and freezes. Mint 13 (based on 12.04) Cinnamon - Actually does not cause a boot loop but fails to load X and spits out the following in the error log: 'Fatal Server Error: no screens found'. If I start in recovery mode, it boots but in the system info it says the graphics driver is in 'fallback mode' (whatever that is) so all the windows are very laggy. Fallback mode doesn't seem to be nearly as bad as software rendering mode though. I tried to delete the xorg.conf file completely thinking that it would solve the no screens found problem but it did nothing. I think the integrated intel graphics are causing the problem.

Mint 13 (based on 12.04) XFCE - boots and runs flawlessly. I have to enable dual screen manually with xranr which is kind of a pain in the ass but hey it works. I think next I'll try to find a way to blacklist the intel graphics.
