193Work Around for VGA and LVDS Display issue in PVR driver
194--------------------------------------------------------
195
196The PVR driver has a issue that for some systems it causes
197it to incorrectly assume that a LVDS display is connected
198while infact a VGA display is connected and Vice Versa.
199If your VGA or LVDS display does not work with
200"cedartrail" MACHINE, then if you have connected a VGA display,
201add the following to the kernel command line:
202
203video=LVDS-1:d video=VGA-1:e
204
205If you have connected a LVDS display, add the following to
206the kernel command line:
207
208video=LVDS-1:e video=VGA-1:d
209
210The kernel boot command line can be updated before BSP build by
211editing the "APPEND +=..." line in conf/machine/cedartrail.conf file.
212
213The kernel command line can also be edited after a image is built by
214editing the syslinux.cfg file in the USB flash device on which
215the image is installed.
