I had the idea of getting my old 19″-screen back onto my table – in addition to my 22″-widescreen, of course!
However, this meant to recompile 350 packages with xinerama-support – sometimes, Windows indeed IS easier than Gentoo….
In order to set up both screens on Linux, I followed the HOWTO Dual Monitors in the Gentoo-Wiki, mostly. As I have an Nvidia with Twinview, I went for this option.
Issueing lspci gave this result for the graphic card:
01:00.0 VGA compatible controller: nVidia Corporation G71 [GeForce 7950 GT] (rev a1)
So, here’s the section for the card in /etc/X11/xorg.conf (note that this readme file was also helpful on some options):
Section "Device"
Identifier "Card0"
Driver "nvidia"
VendorName "nVidia Corporation"
BoardName "7950GT"
BusID "PCI:1:0:0"
Option "NoLogo" "1"
Option "RenderAccel" "true"
Option "AllowGLXWithComposite" "true"
Option "backingstore" "true"
Option "AddARGBGLXVisuals" "true"
Option "UseEdidDpi" "false"
Option "DPI" "96 x 96"
# added this for TwinView
Option "TwinView"
Option "MetaModes" "1680x1050,1280x1024; 1680x1050"
Option "TwinViewOrientation" "RightOf"
Option "SecondMonitorHorizSync" "UseEdidFreqs"
Option "SecondMonitorVertRefresh" "UseEdidFreqs"
EndSection
After restarting X, I had dual screens – and it seems, thanks to KDE, that I don’t even need to load xinerama… Maybe Linux is still just as easy as Windows?
