Thanks Thomas, hello list just realised that my answer email did not leave my box :(... i was writing... well, I am not really interested in the concept of rotation in kms, but using the phone in landscape mode. I am writing a simple phone framework (proof of concept) that is based only on fb or drm. I need landscape mode for a full screen kb. Portrait would do the job, but all draw operations have to be "rotated". It is not tragical, but I thought if the phone is supporting it, why not using it... I tried the settings proposed by you (that differed only in mode.refresh ! :) from my original one). It works and not.. I did not set back the values for "portrait" and when starting the second time the same application, WSOD... new experience... yes.. I really need the landscape mode as default. The little framework I write, as mentioned would benefit if stuff would be rendered by default to landscape. Based on my measurements copying a 640*480 back buffer to front buffer takes 50msec in "non rotated" mode, whereas it takes 250msec if I want rotation when rendering. If anybody has some "sane" timings for landscape, I would really appreciate them.. (preferabbly to have the orientation of USB cable upwards... :) ) rgrds, mobi phil being mobile, but including technology http://mobiphil.com _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
