This is a timing proble between i915 driver and Xorg, add a loop to wait device got ready can avoid this timing problem Liwei Song (2): config: wait for DRM device to be successful initiated fbdevhw: add loop to wait /dev/fb0 get ready config/udev.c | 9 +++++++++ hw/xfree86/fbdevhw/fbdevhw.c | 4 +++- 2 files changed, 12 insertions(+), 1 deletion(-) -- 2.7.4 _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
