Using linux mint in hyper-v resolution problem

I installed Linux-Mint in a gen 1 hyper-v session, and it installed fine.

My main issue is that it setups up in an odd screen size and requires scroll bars. I go to display settings and it say laptop 12xx x 8xx (4:3) resolution, and no option to select 1366x768.

I googled a fair bit but could not make sense of any info. Regrettably, as with many typical linux expert replies, the replies go deep into command line speak but do not lead you in a "tutorial" style approach.

So does anybody know how I change it?


EDIT: googled again and found simple solution

1) Open Terminal

2) Type: sudo nano /etc/default/grub

3) Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:[the resolution you want].

So my line ends up looking like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1366x768"

4) Write the changes and quit nano

5) Run: sudo update-grub

6) Reboot the virtual machine

Now works perfectly. Fix was actually for a ubunto distro but works fine on Mint as well.

So next question is - can I run and rdp server and run this in enhanced mode?

More googling to do :)

Enhanced mode will not work with Mint guests, but you can use remote desktop. Only Linux distro I use is CentOS, here's how I remote to and from a Hyper-V CentOS guest:

Well, I decided to use CentOS and follow tutorial but it fell over at starting service. Any ideas?

cheers

It seems that you have not installed XRDP as clearly shown in your screenshot, error message telling "no such file".

Thanks - I'll have to find out why.

Edit: ok - got xrdp now and installed etc.

Couple of points for other who might try this.

1) Change CentOS resolution

Commands that worked above for Linux Mint did not work for CentOS

This worked from a superuser prompt

grubby --update-kernel=ALL --args="video=hyperv_fb:1366x768"


2) XRDP installation

I had to create a repository first

see extract below from link

Install xrdp on CentOS 7 / RHEL 7


Create a repository file.

# vi /etc/yum.repos.d/xrdp.repo

Place the following content. Once added, save and close the file.

[xrdp] name=xrdp baseurl=http://li.nux.ro/download/nux/dextop/el7/x86_64/ enabled=1 gpgcheck=0

Then I followed @Kari's tutorial thereafter and it worked fine.

Next step - trying RDP:)

Let us know if remote desktop worked.

Yeah - it is working ok but need to optimise display settings a bit - work in progress.

I cannot, for the life of me, see how to set sound. I configured rdp as in screen dump below as discussed on various websites.

I notice sound is set to dummy output in Centos.

I am obviously missing something fundamental!

Now I remember why I am anti Linux. If there was a single version, it would be easier, but the versions have different quirks, and having to use terminal to basic things is a PITA.

Yes, the sound in Linux guests is a problem. I have found no way to get sound on CentOS guest, RDP or not.

I came to same conclusion after much web searching. This is one area Hyper-V is inferior to other tools. MS do not seem interested as they are largely concerned with other Windows vms which can be used in enhanced mode unless Home.
