Questions about gnome-mag + orca
Hello list, Firstly, I'd like to thank the developers of gnome-mag and orca for the significant improvements in the area of magnification. The great orca developers listened to my suggestion and created the option to have the cursor centered while editing and navigating. Kudoz ! Now I have a few questions: My desktop has an AMD Athlon64 single-core (1.8 GHz) and the CPU soars to 100% when I move the mouse. Is this a bug or a limitation? I'm planning on buying a notebook with a Core 2 Duo (T7250 or better) Would this more powerful CPU still soar to 100%? Will it affect heat and battery life? I now have an NVIDIA GF 6600 GT. Would gnome-mag run smoothly on Intel GMA X3100 or NVIDIA 8400 GS?

Re: Questions about gnome-mag + orca
Thank you, Carlos. I am replying to your email using compiz-fusion (the CPU usage barely reaches 3-4%. It would be great if gnome-mag were as easy on the CPU. When you say that the algorithm can be calculated in the GPU, you mean there is a setting I can change to do that, or is this a feature that needs to be implemented?

2008/3/27, Aurelian Radu [EMAIL PROTECTED]: Thank you, Carlos. I am replying to your email using compiz-fusion (the CPU usage barely reaches 3-4%. It would be great if gnome-mag were as easy on the CPU. This is due the fact that compiz uses OpenGL to do it's rendering and it's code is also better to interact with the Xserver. When you say that the algorithm can be calculated in the GPU, you mean there is a setting I can change to do that, or is this a feature that needs to be implemented? The feature must be implemented in gnome-mag. This is not so difficult, since there are lots of good code that do this, these just have to be merged inside gnome-mag. Making this will improve the Xrender performance (the actual implementation) and will also give 3D acceleration support.

Re: Questions about gnome-mag + orca
Hi Aurelian: There may be a number of things going on there. To get things working as good as possible with gnome-mag, I think you currently need to have the following (Carlos will correct me if I'm wrong, I hope!): 1) COMPOSITE enabled in the X server. Since it seems as though you might be using Compiz with the eZoom plugin, I'm guessing this is the case. 2) gnome-mag needs to become the COMPOSITE manager. If you are using Compiz, then gnome-mag may not be able to do so. If this is the case, you should try using metacity. 3) Orca should be using gnome-mag in full screen mode. This can be done in the Magnification tab of the Orca preferences GUI. Having said all that, we have a task for GNOME Outreach Program: Accessibility for someone to get paid to help take the magnification solution beyond where we are now. If someone is interested in this, please let us know! Will Aurelian Radu wrote: Thank you, Carlos. I am replying to your email using compiz-fusion (the CPU usage barely reaches 3-4%.
