Hey folks,
Text mode and X windows display mirroring work nicely for the
ATI driver. Using the keyboard Fn-F8(CRT/LCD) screen swaps
between the displays, but many times you want to see the
output on both displays.
Text mode mirroring
Turn on the external display and
for text mode, go to an nice text console with CTRL-ALT-F2
and type:
See: man atitvout or the project page at http://software.freshmeat.net/projects/atitvout/Code:atitvout detect atitvout auto
X Windows Mirroring
Edit the file /etc/X11/XF86Config-4
and add the following line in the right place
The line is
Option "Display" "Mirror"
and the context is, just inside the "Device" section. I just put it
after the "sw_cursor" option as follows:
Then if you want a nice dangerous root X windows session, just typeCode:Section "Device" ### Available Driver options are:- # sw_cursor is needed for some ati and radeon cards Option "sw_cursor" Option "Display" "Mirror" #Option "hw_cursor" #Option "NoAccel" #Option "ShowCache" #Option "ShadowFB" #Option "UseFBDev" #Option "Rotate" Identifier "Card0" # The following line is auto-generated by KNOPPIX mkxf86config Driver "ati" VendorName "All" BoardName "All" # BusID "PCI:1:0:0" EndSection
CTRL-Left ALT-F2 for a root text console and then
Since you have an X session already running on Knoppix asCode:startx -- :1
DISPLAY :0.0 on the fifth virtual console (CTRL-Left ALT-F5) the :1
option starts the X Windows server on the next free virtual
terminal which is number six. So to switch to this session
use (CTRL-Left ALT-F6).
