3 monitors and Updated xorg mesa drivers for Ubuntu Natty
Comments (2) I’m currently running Ubuntu Natty as my primary OS at work.
My setup is a Precision T3500 workstation that came with two NVIDIA Quadro cards which were a nightmare for Linux support. I heard that ATI cards supported 3 monitors on one card, as long as one of them was DisplayPort. I saw a cheap Radeon HD 5450 on sale for about $40, so I picked it up only to notice that it had an HDMI port instead of DisplayPort. I figured I’d try it anyway and was surprised to find that with the open-source radeon driver, 3 monitors work! One is connected by VGA, one HDMI and one DVI.
I had, however been experiencing random X crashes, and I suspect the problem was with the radeon driver.
Currently testing out some updated xorg drivers found at:
