We have instances that are accessible via vnc but the size are limited to 1280x1024. How can we resize the window to, say 2560x1440?

What we tried: We used xrandr to add a new mode but when connecting the new mode to the vnc, the system stalls and the display is broken. added a new mode using xrandr --newmode xrandr --addmode VGA-1 "2560x1440_60.00" xrandr -s "2560x1440_60.00" ---->This command freezes the system.

So, we upgraded tigervnc from 1.1.0 to tigervnc-server and tigervncviewer 1.8. We're able to resize the window now.

After the resizing of the window, the image contained in it, did not resize even after we added new modes via xrandr. My Colleague Jamal B, figured out that we needed to modify our image to use the video drive qxl. Setting this driver and the resolution, increased the image size.

glance image-update <image-id> --property hw_video_model=qxl Use this image to spin up new instances and you're all set.
