Mouse freezes in Windows guests on Ubuntu 18.04

[CiatronicalX]

Hey All,

I have the same Problem like here: first entry if you emter 'mouse' in searchmask

I use a Asus Vivobook with Lubuntu 18.04 with the latest Kernel 4.17 and latest Virtualbox.

If I work any time in a virtual machine my mouse freeze. I can't click on guest (WinXP) or on my host Lubuntu 18.04

How I can debug this problem??

We're going to need a complete VBox.log, from a complete VM run:

• Gathering the necessary information:
  1. Start the VM from cold-boot (not from a paused or saved state).
  2. Observe the error, i.e. wait for the mouse to freeze.
  3. Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Hey,

I have attached the logfile.

Ronny, you must have missed the capitalized, red, bold, underlined part that said to ZIP the log. Could you edit your message and replace the log with its ZIPPED version?

00:00:00.391897 RamSize <integer> = 0x0000000100000000 (4 294 967 296, 4 096 MB, 4.0 GB)

4096 MB of RAM is too much for a 32-bit guest, it will never see that much, only up to about 3.5 GB. And that's too much, I'd take it down to 1 GB, and see what your needs are.

00:00:01.000762 GUI: 2D video acceleration is disabled
00:00:00.392142 VRamSize <integer> = 0x0000000002000000 (33 554 432, 32 MB)

And the 3D acceleration is disabled as well. Shutdown the VM and enable them in the VM settings » Display. You might also notice that the max VRAM might jump from 128 to 256 MB after that; max the VRAM as well, 32 MB is not quite enough. Then re-install the Guest Additions (GAs) in the guest. Speaking of...

00:00:05.636204 VMMDev: Guest Additions information report: Version 5.2.10 r122406 '5.2.10'

You'll need to update them in any event.

Other than those remarks above, your VM looks OK. Oh, how come you're removed all NICs from the guest? Isolation?

In any event, there might be a chance that because you assigned too much RAM for your guest, your host might have run out of resources down the road and the VM froze. Try with the lower suggested value, you don't need 4096 MB of RAM for a WinXP-32 guest; the template-suggested is 192 MB. With 512 MB if flies!

This is happening to me too, although not just with Windows guests. I have Ubuntu 18.04 as the host, and various Ubuntu and Lubuntu guests, along with Win 7 and Win 10 guests. The host is a 64 bit machine with Nvidia graphics driver.

My symptom was that it appeared both the guest and host desktops froze. On further investigation, it seems to have only been the mouse pointer. I finally tried doing ctrl-t and a terminal window opened in the guest. I shut it down and the mouse pointer started working again in the host.

I seem to have worked around this by turning off mouse integration. Since I did that, many hours of use have not repeated the freeze issue.

I'm ok with running without mouse integration, but thought this might help someone else.

I have set the settings. The machine is still freezing after some time.
After the start of virtualbox, the host has also been frozen for a while.

I have several VM's. Everyone is freezing after a few mouse activities.

Code: Select all

apt-get install at-spi2-core

Fix a bug when I start virtualbox in the console.

A warning remains.

Code: Select all

Qt WARNING: QApplication: invalid style override passed, ignoring it.

I use Lubuntu 18.04
