I apologize if this is a redundant question, but I have tried various suggested solution to increase the guest screen size with no luck. Here is my environment:

VBox Version 5.2.22 r126460 (Qt5.6.2)
vbox guest 5.2.22

I have attached the VM log file. Other vbox guest addtion functions are working (share mouse, clipboard, etc.). Any guidance on this issue is appreciated,
Thanks!

Anyone, Anyone?

There's nothing out of the ordinary in your guest. Try with the latest 5.2.23 test build from https://www.virtualbox.org/wiki/Testbuilds

5.2.23 crashed on loading the VM. Any other suggestions to try?

Thanks

That's all? No logs, no error messages, nothing? Just... pfftttt?

Hit with this too on Windows 10 host. Tried 5.2.23, 6.0 Beta, all had issues.

Went back to 5.2.22, downloaded VBoxGuestAdditions_5.2.23-126769. After starting the CentOS 7.6 vm, unmounted 5.2.22 version of guest additions and mounted VBoxGuestAdditions_5.2.23-126769

All good.

Oops Centos 7.6 will work with 5.2.22, meant RHEL 7.6 here, not sure what the difference between the two CentOS is suppose to be RHEL 7.6

Thanks will give that a try

Well not quite as good as mentioned. There seems to be issues with some mouse functions such that they work on the initial render of a window but that widow has to be closed in order for the mouse to work elsewhere. Sorry for the mislead.

The problem arose because 1) you posted in the "Windows Hosts" section not in the "Linux Guests" section (that's where you're having the problem), and 2) I didn't move it in time. Moving it now...

Part no. 3) was me not noticing the "7.6" part in your guest. Take a look at the thread Mouse only usable within single application after mouse click on RHEL 7.6 (#18124) thread. It's a known issue with RHEL/CentOS 7.6 and it's a problem with the kernel, not VirtualBox. Read the thread for more details...


PS. Funny thing? I got bitten by that too, should have noticed it earlier...

Oh "good"! Then you can give the patched kernel a try.

@Chuckles, as posted in the thread referenced by socratis, I have built a test kernel that has a fix (patch candidate) for the mouse issue here. More testers, the better.

I looked in http://download.virtualbox.org/virtualbox/ and do not see a 5.2.23 guest additions anyhere

Sure thing. If you promise to finish the Greek translation for VirtualBox, why not? We're in RC1 and I'm at 2218 out of 2527 (or 309) strings behind. If you promise to take over that, I'll test your patches

Try the Test builds area: https://www.virtualbox.org/wiki/Testbuilds

Too bad, I only read/write/speak Japanese.

OK I installed 5.2.23 guest additions and the screen sizes correctly now! Thank you all for the help!
