@seekdream1990 请问你是怎么测试的？

5

After upgrade to this rom, still cannot set to 1920x1200 via settings. By overriding the display mode with
echo “1920x1200p60hz” > /sys/class/display/mode
The HDMI output is switched to 1920x1200 but wm size is still showing physical size: 1600x1200 and part of the screen is black.
Any solutions?

cat sys/class/amhdmitx/amhdmitx0/vesa_cap
cat /sys/class/graphics/fb0/osd_background_size
wm size
please input the above command ,then send the result to me

你合入了哪些修改？你是用自己编的固件测试的？补丁都打上是可以共存的，你打了哪些补丁？

kvim3:/ # wm size
Physical size: 1600x1200
Override size: 1920x1200
kvim3:/ # cat /sys/class/display/mode
1920x1200p60hz

And I just tried the latest Ubuntu image, it can correctly detect my display

input following commands when you enter uboot command line
setenv hdmimode 1920x1200p60hz
setenv outputmode 1920x1200p60hz
saveenv
reboot board and enter uboot command line ,then to check if it can display normal

10

设备连接上以太网，再连接wifi，如果正常应该wifi能够正常连接，只是还是使用以太网？是这样

11

我看就是framework的一个修改 其他没有了把

这两个修改也要加上

13

降低以太网评分为30，那不是共存时wifi优先？

14

目前的做法就是wifi 用来访问外网，有线用来访问局域网

15

I tried but no lucks. The env in uboot seems is reset by android after boot.
Here is the log of the tty.

16

after you input setenv hdmimode 1920x1200p60hz ,then enter uboot cmd line , not reboot ,can you see the logo on the screen or the screen is black ?

17

no luck. same as saveenv & reboot. it can boot into android but the rendering and output resolution is 1600x1200. If I override /sys/class/display/mode and wm size, the output resolution is 1920x1200 but the android ui is only showing on part of the screen with black letter box.

you misunderstood me ,after you have entered the three command
setenv hdmimode 1920x1200p60hz
setenv outputmode 1920x1200p60hz
saveenv

then reboot , just go to the uboot command line to see if the logo is displayed on the screen,don’t need to enter Android
