显示器没有edid导致不能显示

[速腾1994]

8.04还可以。8.10以后全部是不能显示，我看了log文件，是没有edid导致，我用别人的显示器就能识别。好麻烦

8.04的时候有EDID吗？EDID是显示设备的身份证，应该一直有的……

[速腾1994]

没有的，我在win下用软件看过，没有。最简单的办法就是看 系统-显示，如果是Unknow显示器，那基本上就没有edid。极度痛苦中

可能EDID丢失了吧，可以重刷解决，但用户无法操作，只能返厂才行……

ls 的对显示器这么熟悉

对显示器不熟，对EDID稍有了解。

ubuntu源里有read-edid软件，可用get-edid读取显示设备的EDID，但读不出序列号，与win下的EDID软件相差很大……
