Joel Bodenmann Posted February 17, 2016 Report Share Posted February 17, 2016 Hello harsha and welcome to the community! This issue is explained in the wiki: http://wiki.ugfx.org/index.php/Linux The X11 driver only uses setPixel() and the performance is therefore horribly slow.

inmarket Posted February 17, 2016 Report Share Posted February 17, 2016 There are several reasons the X driver performs poorly... As X is a development and test platform only for uGFX and thus never intended to be used for production, no effort has been spent in adding accelerated routines. Accelerated routines are not that easy for X. There are some fundamental differences in the way the two GUI systems work and that complicates the writing of these routines. We are not really X programmers. Any code we produce for X is not necessarily going to be the best. If you would like to help in updating the X driver we would really appreciate it. The X driver has already taken us more time than any other driver we have written. Link to comment Share on other sites More sharing options...
