-e RESOLUTION=1920x1080 does nothing

[Felix-neko]

Hi! I've tried to use the key -e RESOLUTION=1920x1080 to set the screen resolution. Alas, the resolution didn't change:

$ xrandr -d :1
xrandr: Failed to get size of gamma for output screen
Screen 0: minimum 1 x 1, current 1853 x 953, maximum 1853 x 953
screen connected 1853x953+0+0 0mm x 0mm
   1853x953       0.00* 

Can you tell me, how to fix it?

Works for me:

$ docker run -p 6080:80 -e RESOLUTION=1920x1080 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc

root@b0385a3ca922:~# xdpyinfo | grep dimensions
    dimensions:    1920x1080 pixels (488x274 millimeters)

Hmm... I'm using the container in slightly other way.

I have run the container in graphical mode first time (in browser), made some changes, deployed some additional software -- and saved it as binary image to use further.

After that it memorized the resolution of my browser and if I'm trying to re-run the container in other resolution with -r RESOLUTION key it does not help.

I've also tried to use the url <container_server>:6080/resize, like it was written in #115 (comment)

I did it under other browser window with much bigger viewport (approximately, 1920 x 1050), but it also did not help: the resolution did not change.

Follow this https://github.com/fcwu/docker-ubuntu-vnc-desktop/blob/develop/DEVELOPMENT.md to get the source, then modify Dockerfile, and make build image is a better way.

It may affect original mechanism If you use docker save to save the image.

Any update?

and saved it as binary image to use further.

How do you do save it as binary to use it later?
