VBox 5.2.20: Linux guest not remembering window size -> fixed after (not in) 5.2.20

[RickR]

Hello,

I'm recently upgraded to VBox from 5.2.18 to 5.2.20 on my MacOS X laptop. The laptop is running OS X 10.14 (Mojave). I have both a Linux guest (CentOS 7.5, fully updated) and a Windows guest (Windows 10) that I use regularly for development. As part of updating VBox, I also updated the guest additions on both guests.

After the upgrade, I noticed that the Linux guest no longer remembers its windows size when starting from the off state. If I resize the window and reboot the guest, it comes back up with the expected size; however, if I shutdown the guest and start it back up, the window takes a "default" (very small) size. Note that this does not happen with the Windows 10 guest. The Windows 10 guest window is always the expected size whether I reboot it or start it from the off state.

This is a regression from 5.2.18, where the guest window for both guest VMs always had the expected size.

I did try uninstalling and reinstalling the guest additions on the Linux guest, but that made no difference.

I've attached the log from a session where the VM was started from the off state and the guest window came up with the wrong (small) size.

Also seeing this with Ubuntu 16.04 guest on Ubuntu 16.04 host. (reproducible)

This behavior is only happening in the login window, right? It was changed a few releases back. But as soon as you login, the desktop returns to its normal size, right?

Hi,

i am experiencing this problem on several, but not on all of my VM's. Interestingly: after reinstalling the *.18 version of the GA, the guests behave fine again. After a while, i did retry the GA upgrade and the issue reappeared. => some regression in the guest additions only! (The guests, where the issue is easy to reproduce, are based on debian 9 stable... just as the host is. And the size does NOT get restored properly. BTW: in my case no login, using autologin instead.)

No, at least for me, the window remains the same (incorrect) size after login.

This should be fixed in the current test builds<1>.

I installed the referenced test build and associated extension pack, and I can confirm that for me, at least, it does fix the issue. The behavior is now the same as it was in 5.2.18.

Thank you!

confirming the same: issue resolved in the test build. thank you very much. :-)

In Fedora 29 Version 5.2.22 r126460 (Qt5.11.1) is bug not resolved!!!

Renatk: please provide more details (Host, guest, machine log file).
