Guest Additions 5.0.24 incomplete install?

[dwelden]

I have an issue with VB and GA 5.0.24 on two different Linux VMs. After logging in, I have to restart LightDM (or MDM on Mint) in order to get the window manager working. I have to do this everytime I login. I had 5.0.22 installed previously, and installed 5.0.24 from the ISO in the VBox Program Files folder on the Windows host.

Is the uninstall of old/install of new GA not properly updating a config file or something?

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Log is attached. Here is the screenshot of what I get upon initial login to Mint.

It also looks like others are having a similar issue viewtopic.php?f=3&t=78531

00:00:04.408521 HM: HMR3Init: Falling back to raw-mode: AMD-V is disabled in the BIOS (or by the host OS)

I would first fix the above issue and then see what happens.

It is disabled in BIOS and I don't have BIOS password. That is why I am running a 32-bit instead of a 64-bit guest OS.

This problem did not present with earlier versions of VB and GA.

Without hardware acceleration the guest will lag horribly ( see the log file ) and could produce this issue. I do know that software acceleration in VirtualBox does not get a lot of love/attention any more. Other than that I have no idea what to tell you at this point other than regress to a version that works and post a ticket at bugtracker.

According to the guest OS, I should have hardware acceleration:

Code: Select all

Not talking about the graphics acceleration read the post above your bios hardware acceleration AMD-V

Oh, I see what you are saying. My admittedly limited understanding was that this was more important for 64 bit guests, but sounds as if you are saying that is not necessarily true. Unfortunately, I am limited to 32 bit guests as my BIOS is locked and I do not have password.

I can say that I have run 32 bit guests previously with this same configuration prior to 5.0.24 with no appreciable issues. A bit slow at times, but my CPU is not that beefy anyway.
