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%.
