Message "Running in software rendering mode"

[dantist]

I have the same problem with Linux Mint 18.1, VirtualBox 5.1.12 r112440 and Windows 7 64 Bit. I have already purged the pre-installed guest addons and installed the ones that come with VirtualBox, but the software mode-message won't disappear and Mint runs kind of laggy. Is there anything else you need to consider, e.g. BIOS-settings like enablen VT-x?

With the VM shut down completely (not paused or saved), right-click on the VirtualBox Manager and select "Show Log". Save the "VBox.log" (just the first one), ZIP it and attach it in your response (see the "Upload attachment" tab below the reply form).

Thanks socratis, I have saved the log file. Funny thing is that I purged the virtualbox-addons and installed the stock ones for the fifth time today, and now the "software mode"-message is gone. On the other hand the screen now seems to have an almost invisible flickering and I can't leave fullscreen-mode with the host-key any more - the menu-bar also keeps disappearing. Maybe the stock-addon isn't fully compatible with the latest Mint-version. Anyhow, I am attaching the log file, hopefully it contains some useful information. I had to ZIP it because of the forums file size limit.

I had to ZIP it because of the forums file size limit.

Not because I specifically told you?

One major and one minor point in the logs:

00:00:01.432437   NumCPUs           <integer> = 0x0000000000000004 (4)

You have 4 cores, you assigned all of them to your guest. Not a great idea. Take them down to 2, max 3. Your processor: https://ark.intel.com/products/88195/In ... o-4_20-GHz

Just out of curiosity, have you tried with something smaller? Let's say 1280x1024x32?

Indeed, I must have missed that. Sorry

I have now reduced the cores to two and switched off fullscreen mode to lower the resolution. I can't see the strange flickering any more, but the colors seem to be off. e.g. the wallpaper is too bright, as you can see in the attached screenshot. This also happens in fullscreen, I just haven't noticed it earlier today.

Color calibration has never been hardware corrected (as far as I know), aka not VirtualBox related? Check you host and your guest color calibration settings maybe? I mean you're running your guest at 32 bit depth, which is I assume the same one as your host, so there's no "translation" taking place.

Finally, try not to manually resize the window to weird numbers. Change the resolution to something comfortable from within the guest. Computers really like nice, hexadecimal numbers. Just in the 1 1/2 min that you run, you changed to the following resolutions:
