Windows 10 - Display Driver?

[doron]

Hi,
I'm running Win10 x64 with VB 4.3.20. In general, things work well. However I noticed that the display driver has the yellow exclamation point in Device Manager.
"Windows has stopped this device because it reported problems".

The reason this matters is this: I tried to configure 2 monitors for this VM. Although configured in VB, Windows sees only one monitor; and when tracing this issue, I ended up with the Device Manager problem.

Anything I can do to configure 2 monitors for my Win10?

Windows 10 is not fully supported yet because it's still pre-release so somethings may not work. That being said, did you install the guest additions and are they working?

Thanks. Yes, guest additions are installed and are working.

Your guest will not see more than one monitor if you have not selected more in the guest settings.

Even then I am not sure it works in Win 10 yet.

Of course. Naturally I configured 2 monitors in Guest Settings.

Even then I am not sure it works in Win 10 yet.

That is what I'm trying to understand here.

Thanks.

Running OSX 10.6.8 on a 1920x1200 display with VBox 4.3.20. Guest Win10 build 9841, with GA 4.3.20 installed.

• Configured Win10 Preview guest with two monitors in the VM settings. Guest was previously running not in full screen, but in windowed mode (1280x1024).
• Launched Win10. Right-click on the desktop, Screen resolution.
• Control Panel shows two monitors. #1 was set to 1280x1024, #2 the 'Resolution' was disabled. 'Device Monitor' showed two monitors. No warnings.
• Changed the 'Multiple Displays' drop-down from 'Show desktop only on 1' to 'Extend these displays'. A second window opened up with a 1024x768 resolution. Successfully changed #2's resolution to 1280x1024. 'Device Monitor' showed no warnings.
• The options 'Show desktop only on 2' and 'Duplicate these displays' produced erroneous configurations.
• Upon restart, VBox opens with one window, but way before the login screen appears, two windows/screens are visible.

Okay. Mine is: Win7 x64 host, VBox 4.3.20, Win10 build 9879. GA installed.

Two monitors configured in VM settings. Guest running in windowed mode.
"Screen Resolution" control panel shows one monitor.

@socratis@, when you go to Device Manager in Win10, what do you see as display devices? Does it appear to be working well or is there a yellow exclamation point?

EDIT: From Event Log: "Display driver VBoxVideoW8 stopped responding and has been successfully disabled."

Host: W7x64pro, Guest:W10x86pro
VB 5.0.8 r103449, latest GA installed

Dual monitor, where the VB-screen on the second monitor just disappears, and I get the message:
"Display driver VBoxVideoW8 stopped responding and has been successfully disabled." appears.
Display settings now shows only a single monitor, where previously there were two.
Also the resolution is now wrong, 1024x768, instead of 1222x902 that gives me full screen on monitor 1.

This has happened twice right now, in both cases when the guest has been idle.

Any ideas?

EDIT: Now it happens all the time. Start VB with the guest. Everything looks fine for a few seconds, then the display driver dies. This was stable during the last week or so, after I upgraded to VB5 and W10. Suddenly, today it has started acting up. Annoying...

EDIT: So it happened again! Someone asked about what shows in device manager. There I have two "Generic Non-PnP Monitor" entries. So that looks fine. W10 "Display Settings" also shows two monitors, but the VB-window on my second monitor closed itself.

EDIT: If I "Adjust window size", I get the second screen back!

Similar to other occurrences reported, this occurs often, and mostly when the guest is left idle for any length of time. Sometimes you can re-enable the 2nd monitor, sometimes not.

To me, this looks like Windows 10 is aggressively disabling drivers it deems "non-responsive", and this might not strictly be a VirtualBox issue, or at least might be confined to the video driver's perceived responsiveness.

Wondering if there is a way to tell Windows 10 to stop monitoring the VBox video driver, or if this is just a bug in the video driver that actually needs fixing.

Here below are the manual steps to resize windows 10 screen to its normal size

1- Open device manager

2- Select Virtual Graphics Adapter for Windows 8 > Update Driver Software

3- Select Browse my computer for driver software

4- Select Let me pick from a list of device drivers on my computer

5- Select VirtualBox Graphics Adapter for Windows 8 for x.x.xx.x > Next
Where x.x.xx.x is the current version of Virtual box

Thank you, I've been having the same problem and this worked beautifully! It would be nice to come up with a batch file to do this, but this is at least faster than rebooting the VM constantly.

This keeps happening to me too, generally when my windows guest goes into screensaver.
the problem is, when i follow the steps above, i do not get a choice of driver for windows 8?, there is only one option: (see screenshot)

should i have more choices?

cheers

***EDIT** switching in and out of full sxcreen mode does bring the second monitor back online, but this is not a satisfactory solution!
