@duanzhh 找到原因了，mad，智障自己，流控打开又给自己在system_config.fex里面关闭了

@yixiuge 大佬你好哈！最近我也在搞A133上ubuntu18.04的xfce桌面，我发现必须要将显示引擎端的比如fb0_format设置为rgb565格式，xfce桌面才能正常显示，如果使用默认argb8888格式，xfce桌面显示黑屏。大佬，请教一下如果想设置成xfce桌面argb8888显示，该怎样操作啊

@yuzukitsuru 大佬这么晚还没睡觉，太辛苦了

uboot阶段显示正常，kernel阶段显示概率性不正常，有锯齿，系统ui端又是正常的，从de截屏看，在de阶段合成图片出了问题，请问这种有解决思路吗

不正常图片（从de截屏得到的）：

正常的图片：

有大佬帮忙分析下可能存在的原因吗

@whycan 晕哥，我使用tina的sdk调试xr829蓝牙时，一直出现这种问题，Initialization timed out.，请教一下这种可以从哪些方面排查问题啊：
