<div>
<pre>When using a dumb framebuffer driver like vesafb, a switch from X to another VT
produces a black screen. This is because of vg_set_custom_mode disabling the
CRT output in DF_DISPLAY_CONFIG and DF_VID_MISC.
Before RandR support was introduced (i.e. before d681a844e), LXLeaveGraphics
had a final call to lx_enable_dac_power that reenabled the output.</pre>
