Guest window size decreases on login (Linux)

[Patrick Headley]

I had one OpenSuSE 15.2 guest machine unexpectedly go back to a resolution of 1024X768 after rebooting and logging in. I was able to click and drag the window to increase the display size to fix the issue.

Things that didn't work were: using the display settings within the OS to set a resolution Using the View menu to set Auto-resize Guest Display and then use the View menu to set the display size for Virtual Screen 1. In both cases the screen would resize as expected but, after a reboot and logging in again the screen size would jump back to 2014X768. When 3D acceleration was turned off I could see that the screen size was initially at the selected size before jumping back to 1025X763. With 3D acceleration turned on I cannot see the jump.

3D acceleration was initially turned off. Turning it on didn't change the symptoms. Using VMSVGA

Hi LinxPatrick,

Could you please attach VBox.log?

Where will I find the log? Both host and guest are Linux.

Hi LinxPatrick,

Depends on how you've organized VMs in VirtualBox Manager. For example,

/home/<user>/VirtualBox VMs/<VM name>/Logs/

You can also access log file via VirtualBox Manager by doing right-mouse-click on a VM name -> Show Log. Please attach log as a file.

Attached logs. One of them is a duplicate.
