Re: Post install dual-head nouveau setup?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I did remove the xorg.conf as well as all the nvidia packages from rpmfusion and the nomodeset and rdblacklist=nouveau from the grub.conf. I then rebooted and the primary head only came back up, but at a very low resolution, and using vesa. I then ran system-config-display and was unable to do much more than bring the primary head up to about 1024x768 (or was it 1280x1024?) using the nouveau driver. I could not activate the second head at all.

You mentioned xrandr... Last I knew it didn't do much. It must be the missing link. If it's required to configure the display it needs to be integrated with system-config-display though.

Thanks.

I tried removing the nvidia driver (from F13 RC2 + updates) and installing
mesa-dri-drivers-experimental on my dual monitor system. The result was not
pretty. I could get one and only one screen up, and not at the 1920x1080 the
primary HD display is capable of (connnected via VGA, not HDMI) I could not
find any way of adding the second head with system-config-display as there
is no "second" video adapter available. I have not found any HOWTO for
enabling the second head. Pointers welcome, thank you.

I use a dual display with my nouveau based laptop + DVI and it just
worked. The two panels are 1440x900 and 1680x1050. You should be able
to use the display option from the main menu or alternatively what
does running xrandr return from the command line? It should return the
two screens, what they're capable of running, and what they are
running at. You should be able to do something along the lines of
'xrandr --screen VGA-1 --auto --right-of VGA-0' to enable it. When you
removed the binary driver did you also remoove any of the xorg.conf
and binary kernel modules. The nouveau shouldn't need any xorg.conf so
that might be causing issues if  the other driver had one.
