Cockpit: machines: VNC Vertical Sizing is Off

Created on 10 Jan 2018 · 9Comments · Source: cockpit-project/cockpit

The vnc viewer in the latest release doesn't appear to be handling vertical resizing - part of the screen gets cut off and unlike the x axis, the y axis doesn't offer scrollbars.

Might I also make a suggestion at the same time... Could a button be implemented to allow full screen viewing of the running vnc session?

Having a full screen button or the option of opening the VNC in a different tab would be really nice

Real full screen can be achieved just via external viewer, like remote-viewer.

@andreasn , what do you think?

We might i.e. open a new tab with just the single no-vnc session. Or use just the whole plugin-space. It would be up to the browser if it can resize to full screen (like F11 key in FF).

@mareklibra true but this has value for those who do not want to open up vnc externally in their firewall; it's only a suggestion really.

My main point though is around the vertical sizing - as it makes the functionality unusable.

@mareklibra any update on the scrollbar issue?

The vnc console is still unusable for me because of this.

@dcrdev , this needs to be fixed. Unfortunately, I did not have time to get to it so far.

I know this is closed but adding some information that might help someone else. Feel free to delete.

It happens sometime when resolution changes (ex.: login screen has a different resolution than the session). The workaround is to modify the size of your browser (restore down then maximize or modify manually).

I am also loosing the keyboard when navigating in other menus of Cockpit. If you experience it, you can change the console type to Desktop Viewer and back to VNC or, faster, just click in the black area of VNC (left or right side on the capture above) and then your keys will be captured again by VNC instead of the browser.

Since we are in the workarounds, in the Terminal you can Copy and Paste if you do CTRL-A before CTRL-C and CTRL-V.

My vote for full screen or a way to hide the left menu to have more space. Having 2FA authentication with Cockpit is great and this is on the the reasons why I do not access VNC directly by opening another port in the FW.
