Hello Everybody,
My name is Luis Alberto. This is the first time I write in this list. I do so
to ask for advice on how to properly configure my X server. I have
usually done well with the information on the Internet, but I have been
two hole days trying without results, and it is very frustrating as it
worked with ubuntu 9.04 32 bits.
I have been using Linux for a while now (mainly Debian and Ubuntu)
usually smoothly, but I have just done a fresh install in my AMD 64 X2
with a GeForce 6500 and two monitors (SAMSUNG SyncMaster 901N
through VGA + HP L1925 through DVI) of a ubuntu 9.10 amd64.
I have not been able to get 'nvidia' driver to work, so I need to set my
two monitors with 'nv' driver (I guess). I have tried lots of things without
luck.
I am able to get a large desktop with option 'DualHead', but the
configuration is not the one I need (I need two different displays, so
that when I maximize a window, it stays in one monitor). Without the
'DualHead' option, the X server simply crashes (One monitor is
completely violet, and the other one blank). I have two questions:
a) With option 'DualHead' on, if I type 'xrandr -q' I get:
Screen 0: minimum 640 x 200, current 2560 x 1024, maximum 2560 x
1024
default connected 2560x1024+0+0 0mm x 0mm
2560x1024 76.0*
2048x768 76.0
1600x600 73.0
1280x480 73.0
1280x400 0.0
640x400 0.0
640x240 0.0
640x200 0.0
Why don't I get 2 screens? Is there some way to see 2 screens?
b) With option 'DualHead' on, the rest of the parameters (I mean,
RightOf, a new screen, etc ...) do not have any effect. Is it normal? I
post here my current xorg.conf file. If a remove the option 'DualHead', it
doesn't work. Any suggestions please?
