Switchy

Source (link to git-repo or to original if based on someone elses unmodified work): Add the source-code for this project on opencode.net

Description:

Switchable graphics is relatively new, but it's cool to have the GPUs under control. Prerequisites are:
->vga switcheroo kernel module
->open source drivers for both cards

This plasmoid shows status and can switch between GPUs. Helper program is needed (vgad).

Compile (look at README file)
copy vgad to /usr/bin
add "vgad &" without quotes to /etc/rc.local

There's something wrong with vga_switcheroo. Does it work without the plasmoid? Is the path correct?

Switching cards in runlevel 3 using "ECHO DIS > /sys/kernel/debug/vgaswitcheroo/switch" for discrete and "ECHO IGD > /sys/kernel/debug/vgaswitcheroo/switch" for integrated graphics works fine.

Here is the content of my switch file:

0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0

Nevertheless, Switchy crashes (even 1.0 release). Any suggestions?

Could you please post backtrace? It would really be useful here.

Also what distro are you using?

I am using openSUSE 11.4 64bit with KDE SC 4.6.3. My integrated graphics card is an Intel Arrandale chipset (uses free i915 driver) and the discrete adapter as an ATI MobilityRadeon 5650 (uses the free radeon driver). My XOrg stack is version 7.6_1.9.3.

Let me know wether you need any more information or contact me on Skype (andreas.demmer), ICQ (103924771) or Jabber (andreas.demmer.1977@googlemail.com).

The backtrace is following:

Strange. I posted on kde-look only. Maybe platforms communicate, that's why they are "polluted"

I'd call it an epic fail mate :D

Useful plasmoid for someone with 2 gpus. But please keep kde-look and kde-apps separated. There is enough pollution by qt-apps here. Plasmoids should be presented on kde-look.org, and not cross posted
