Hi, I'm trying to get xorg-server + xf86-video-fbdev working on my device, and I'm hitting problem:
pixclock value of fb mode on my device is 260000 picosecs, and due to picosecs <-> khz conversions in xorg-server I'm getting rounding error: 1000000000 / 260000 = 3846 1000000000 / 3846 = 260010 (Look through xfree2fbdev_timing and fbdev2xfree_timing functions in fbdevhw.c for more details) xorg-server gets mode via FBOIGET_VSCREENINFO (pixclock = 260000), converts it to its own format, then converts it back to fbmode (due to rounding error pixclock - 260010) and then tries to set mode with pixvalue 260010 via FBIOPUT_VSCREENINFO ioctl, but driver sets it back to 260000, and xorg-server fails to startup with this message: (EE) FBDEV(0): FBIOPUT_VSCREENINFO succeeded but modified mode. With this patch: https://svn.pardus.org.tr/pardus/playground/memre/arm/repos/cortex- a8/x11/server/xorg-server/files/oe/hack-fbdev-ignore-return-mode.patch xorg- server starts with no problem, but it's ugly hack. Is there any sane solution to fix my problem? Regards Vasily
