Because it's been asked to set the hardware back to text mode, which requires reprogramming the GPU, which takes time. 200ms is more time than it probably _should_ take, but you haven't specified (either in this email or in the bug you link to) what GPU this is and which driver you're using, so I can't be any more specific about what exactly is taking so much time and how it can be avoided without that. - ajax _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
