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