这是前后两个屏幕的资料对比
更换前什么问题都没有
更换后，安装黑屏通过外接显示器安装好  ，还是不能显示在新屏幕。在开始按E  修改增加Radeon .modeset=0 .勉强进入系统。进入更新gurb。但是  分辨率只是1280*720  不是以前的1366*768.各种折腾。问题也没搞定。最近还发现休眠后无法唤醒  。只能强制关机。我看看我还是将就着用win  。。。。。。。。。。。。。

从日志没看到什么问题
LG的monior接在LVDS-1上面，1366x768
LEN的monitor接在VGA上面， 1440x900
X也没看到什么错误

不过有两块显卡，可以从bios里面分别禁用一块试试看

我自己分析了。是显示屏跟显卡的通信问题驱动没处理好。

你能帮我翻译下这个16进制不？我把 xorg 相关的配置都打包了，你看能不能给修改下配置成1366 768

i2c-dev加载了?

应该可以直接get-edid | parse-edid，然后把modeline复制一下写到X的conf里面

也可以用xrandr看看

@yanbowen

xrandr --auto?还是什么?

我觉得主要原因是换的屏幕与以前的品牌不一样了。

多谢，先凑合用吧。15.6 屏显示 1024 768 有种压扁的感觉。不过也不影响使用。

他这是驱动没有正确加载，X fallback 了，xrandr 看不到信息的。

啥意思呀？
我看内核radeon的没有问题
你是说X没用modesetting/ati/radeon，用了fb?
我看X日志里面的分辨率菜也是正确的呀

xrandr 这种输出一般表示 X 用了默认设置，也就是没有找到合适的驱动，用了代码里的默认值

看日志，两块卡。一个走的radeon，一块走的modesetting，没有问题的。从x的日志来看，两个显示屏的edid都分别读取到了，而且也没有异常。就换了个显示屏，会不会继续使用了之前的.config/目录下的之前配置？https://bbs.deepin.org/user/33250

我感觉也是他说的那样就是加载后然后失败重新返回因为中间出现过撕裂的 grub界面。不过这是加参数后的，不加参数，过了grub 出现光标闪两下黑屏。不知道是不是只是关掉背光。win下没事。
