Hi, I have been using drm-next-kmod for a while now, and it works fine, except for this little annoying thing. On this Lenovo ThinkPad Yoga 12 (i7-5500U) I have kld_list="/boot/modules/i915kms.ko" in /etc/rc.conf Shortly after the module is loaded, the console (vt) refreshes only about every 5 seconds or so. This only happens on the builtin laptop screen, when I have an external monitor connected the external monitor is working normally. (Display is output to both, and the internal screen still has the slow refresh) Starting X and switching back to vt or quitting X and it is working normally. Another thing that might be related; switching windows in X with alt-tab (xfce) is also slow (on the order of 5 seconds). I have another laptop I am using drm-next-kmod on (Pentium N3540) which doesn't show any of this behavior. Any idea? Thanks, Jakob
