Has anyone had success with 3+ monitors (on 1 computer) in linux with<br>
Core2-era hardware (or otherwise)? Note: I don't care about 3D<br>
performance at all, just 2D linux desktop (no compiz!) with the very<br>
rare 3D app that won't be at all important.<br>
<br>
I have an existing 2 monitor setup but I want to move to 3 or 4 after<br>
a recent monitor death.<br>
<br>
I see two ways forward, but both have uncertainty:<br>
<br>
1. Add a 2nd (cheap) PCIex card to my Intel D975X board (has 1 x16, 1<br>
x8, 1 x4 slots).<br>
<br>
2. Swap out my existing card for a new ATI 3-display card (like 7750).<br>
<br>
<br>
#1 will be cheaper (I probably have some here already), #2 may be<br>
faster, but will require many expensive adapters to be purchased, as<br>
well as the card.<br>
<br>
Sounds easy. But there are many gotchas:<br>
<br>
1.<br>
a) 2nd card may not work at all: some boards have issues, some cards<br>
have issues.<br>
b) 2nd card may work, but at 1x. I previously ran a system on x1<br>
video (even though it was in an x4 slot!) and even 2D was slowed down<br>
by the x1. x4 is the bare minimum I want to run. Many board/card<br>
combos don't "downspeed" very well, and often just go to x1<br>
c) will linux be happy with 2 video cards (with my board)?<br>
<br>
2.<br>
a) do the free radeon drivers support the new Eyefinity (3+ monitor)<br>
spec or am I forced into proprietary drivers (yuck)?<br>
b) and do the proprietary drivers even support it and happily in<br>
xrandr and xinerama, etc?<br>
<br>
While in theory there should be no problems, I've learned "weird" video<br>
card issues abound in reality. I'm trying to minimize delays waiting<br>
for parts to try, and expense. As such, notes like "I've done it with<br>
X and Y" would be most helpful! Or, "I'm really really sure X and Y<br>
should work" would also help :-)<br>
<br>
PS: I'll be doing super thin bezel models in the shape of "BO" (2<br>
horizontal, 1 vertical) with one of the B's inverted because the bottom<br>
bezels aren't as small as the top ones.<br>
<br>
Thanks!<br>
