Hi,

I updated the xrandr Howto with TV-Out support and other nice features with 
the new xrandr. (Thank you, Alex!)

I have test the radeon-git-driver and the xrandr-git-version and I found the 
following problems: (with T41p)

1.) the new driver generate very big fonts on my screen compared to the 
standard debian driver from experimental 6.6.193-1 or 6.6.192 (feature or bug 
or changes with dpi ?)

2.) google earth is really slow and disabling "low-impact fallback" 
with "driconf" let the system crash after starting google earth. This is 
working with an old version of the driver (e.g. 6.6.3 debian lenny)

3.) AccelMethod EXA is not usable - moving windows is very slow. XAA seems to 
be working great.

Any ideas?

Nils



Updated Radeon-TV-Out & other features-Howto: (based on advices from Alex and 
other in the thinkpad-mailing-list)

git-ati-driver:
---------------
1. First make sure you back up the existing radeon (radeon_drv.so) and ati 
(ati_drv.so) drivers.
2. install the xorg-dev, mesa-dev, xserver-dev, drm-dev, libtool packages for 
your distro (e.g. debian: xorg-dev, libgl1-mesa-dev, xserver-xorg-dev and 
libdrm-dev, libtool)
3. git-clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati
4. cd xf86-video-ati
5. git checkout origin/randr-1.2  (Git-Version 1.5)
    git checkout randr-1.2 (Git-Version 1.4)
6. ./autogen.sh --prefix=/usr (or any home-directory, but then you have to 
copy the files manual to the correct directory)
7. make
8. (sudo) make install (or copy the files radeon_drv.so/ati_drv.so)


xrandr:
--------
1. git clone git://anongit.freedesktop.org/git/xorg/app/xrandr
2. cd xrandr
3. ./autogen.sh --prefix=/usr

4. make
5. make install
or
4. just copy xrandr binary to /usr/bin/ (don't forget to backup your old 
binary)


activate S-Video port
1.) xrandr --addmode S-video 800x600
2.) xrandr --output S-video --mode 800x600

(setting tv-standard to PAL: xrandr --output S-video --set tv_standard pal)

vga output:
--------------------------
turn off vga output: 
--> xrandr --output VGA-0 --off
move vga output right of LVDS output
--> xrandr --output VGA-0 -right-of LVDS
switch the mode on DVI to 1280x1024
--> xrandr --output DVI-0 --mode 1280x1024
automatically set up all connected outputs
--> xrandr --auto
