Package: fglrx-driver Version: 1:11-8-3 Severity: wishlist The new version of the tool aticonfig includes a new function for switching the graphic card in computers with two GPUs (these are usually sandybridge based laptops) # Select ATI (discrete GPU) aticonfig --px-dgpu # Select Intel (integrated GPU) aticonfig --px-igpu # List which one is activated aticonfig --px-list See test example: For this to work, the aticonfig executes a script ( /usr/lib/fglrx/switchlibGL and /usr/lib/fglrx/switchlibglx ) that is not available at Debian, so the tool fails to switch graphics properly. The wiki of Gentoo has more information about this scripts: http://en.gentoo-wiki.com/wiki/Fglrx-hybrid-graphics I have implemented this script for Debian, it uses update-alternatives to switch between the GL libraries, and also updates the xorg.conf file for each GPU creating symlinks. The configuration for the ATI card (xorg.dgpu.conf) is generated with "aticonfig --initial" and for the integrated one, it is simply a very basic skeleton configuration, so the X server is able to auto-detect the devices. I also created a Debian package for it. Here is it: http://people.igalia.com/clopez/fglrx-hybrid-switch_1.0.tar.gz Simply untar and do the debuild to generate the package. Feel free to improve and/or modify as you desire. I wish see this included in Debian. Thanks! Here is some test: # echo "xhost local:"> /etc/X11/Xsession.d/999-xhost # aticonfig --px-igpu PowerXpress: Integrated GPU is selected (Power-Saving mode), please restart Xserver(s) for changes to take effect! # /etc/init.d/gdm3 restart Stopping GNOME Display Manager: gdm3. Starting GNOME Display Manager: gdm3. # DISPLAY=:0.0 glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 296 frames in 5.0 seconds = 59.011 FPS # aticonfig --px-dgpu PowerXpress: Discrete GPU is selected (High-Performance mode), please restart Xserver(s) for changes to take effect! # /etc/init.d/gdm3 restart Stopping GNOME Display Manager: gdm3. Starting GNOME Display Manager: gdm3. # DISPLAY=:0.0 glxgears 20585 frames in 5.0 seconds = 4116.958 FP _______________________________________________ Pkg-fglrx-devel mailing list pkg-fglrx-de...@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-fglrx-devel
