Title: Get Ubuntu to recognize my 4 video cards. Post by: sgravina on June 11, 2011, 02:39:04 AM I have two motherboards. Each runs Ubuntu 11.04. One has 3 5850s video cards. The other has 2 5850s. It took me a long time to get these setups to recognize all the cards. I eventually did it by booting into recovery mode and restarting X. I don't know why this works.
But now I have two brand new 5850s that I want to add to the second motherboard. My rebooting trick is not working. The operating system only recognizes two video cards. How do I get Ubuntu to know about all the video cards I have installed? Sam Title: Nevermind. I didn't have the power connected. Post by: sgravina on June 11, 2011, 03:04:21 AM I connected the power cables to the two new cards but didn't connect the the other end to the power supply.
It all works now. I tried to delete this topic but the board wouldn't let me. Sam |
