16.04 - Configuration / Login Issue

[johnkattenhorn]

Not urgent as I just wanted to try out the experience.

I followed the instructions listed here https://blogs.technet.microsoft.com/virtualization/2018/02/28/sneak-peek-taking-a-spin-with-enhanced-linux-vms/

I see the default xrdp login prompt:

No login details work; if I disable the enhanced session then it drops back to normal shell and I can use as before.

Let me know if there's anything else you want me to try and send to help before official launch

Does it give you any more information in the failure context? Also you could check /var/log/xrdp.log and /var/log/xrdp-sesman.log for any extended error info why the session failed.

[dankseman]

There is a bug in the login. I created a user called M (upper case) and it would not login in. I discovered by trial and error I had to use lower case m.

Without further testing, I do not know if you have to enter it all as lower case or reverse the case e.g.

Mike ----> mike or mIKE

password was no affected.

@jterry75 - I'll try to grab those details when I'm back in my office at the end of the week; @dankseman -I wonder if that's my issue - I'm pretty sure Login is Installer in the machine I was trying.

[johnkattenhorn]

@dankseman - I had to use all lower case but it worked for me, the experience is awesome.

[johnkattenhorn]

@jterry75 - No errors apparent in either of those files and it works if I login, is the current user experience to see the xorg login screen as I screenshotted above ?

[dankseman]

Can you see pc drives - it does not work for me.

@dankseman - not working for me either; I see this

[dankseman]

You have to select drives to see from the enhanced config screen that popups up to set resolution. I get the drives listed but no details.

@dankseman - Doh - of course, now I see the drives but nothing appears when I click through one

[dankseman]

Log it on exist github comments. Until this is fixed enhanced option is pretty useless apart from cut and paste. Real disappointment is no sound.

I know this is beta software and is not meant for ubuntu 16.04. However performance was poor. Opening apps and visual effects are painfully slow. Have I missed something? @dankseman, I can personally see past the sound but not the performance. I am by no means an expert in virtualization. I dont understand why RDP protocol is used to gain access to a virtual machine? How can one implement hardware acceleration through RDP? Hopefully the final release on ubuntu 18.04 will be better. I had hight hopes with HyperV as WSL is also unusable Slow IO performance WSL .

[dankseman]

The xrdp should not affect performance of the vm. It only adds some extra interfacing eg drives (not working properly), access to pc clipboard etc. that you do not get in basic Hyper-V mode.

We're tracking the drive mounting issues in a separate issue #6 .

@Fabyao - how much resources ( vCPUs and memory) are you allocating to the VM? Describing the experience as "painfully slow" has not been my experience, so something must be aloof :)

@dankseman using the RDP protocol does indeed affect the user-perceived performance of the VM. Since it is it's own protocol with it's own implementation for encoding/decoding. See for yourself - go look at the webgl aquarium sample in enhanced mode vs basic mode.

[dankseman]

Without this working, the enhanced mode is pretty useless. You can set screen sizes easily enough by editing config files. The only plus then is cut and paste but that is all. With easy disk access and SOUND, then this would be great. Until the Linux in Hyper-V is a poor experience compared with vmware etc.

@cwilhit Thank you for your reply. I have allocated 4 CPUs and 8GB of Ram I also tried with RemoteFX 3D Adapter. A simple mouse over effect is delayed by about 3 seconds. Dragging windows is also lagging. I agree with @dankseman that VMWare has better performance/ user experience. No lags at all. As mentioned before I am no virtualization expert but I am not convinced that adding yet another layer (XRDP) is a good idea. This is based on my experience with VMWare and Open VM Tools. I appreciate VMWare might be based on a different architure, however you might find the source code (see link) to be of interest
