Multiple issues getting native feeling

Hi there,

I'm trying to run Ubuntu arm with KDE plasma on Mac M4 Max on most current

Sadly I hit one bumper after another. Basically I only want to the most native feeling as possible.

My issues so far:
1. Resolution
Display setup: I can't set the correct resolution in Linux. I found one that is okay but not the ratio of mac. I tried with different parallels options like Retina or scaled and fullscreen settings. No luck so far.

1a. Multi display setup is hell
At first I though every was...

Multiple issues getting native feeling

Why can't I change so I use native resolution Via Ubuntu 25.04?

Parallels Desktop Ubuntu 24.04 (With Rosetta) running x86 program

invalid@example.com (Mac67) — Sat, 04 Apr 2026 18:22:42 +0000

I am an embedded Linux software development engineer and need to use the cross toolchain provided by Linaro. The compiler is arm-linux-gnueabihf-gcc, version 2014.11. I specifically chose Ubuntu With Rosetta for installation. I referred to the content in https://kb.parallels.com/129871, but my compiler still cannot run. What should I do? Thank you！

I can barely see Kali Linux

invalid@example.com (joblo) — Sat, 04 Apr 2026 10:45:30 +0000

I installed Kali Linux ISO on Parallels on my Macbook air 2015. Everything including the wifi seems to be working. I'm new with Linux so I'm not sure what to do. Everything on the screen is WAY too small. How do I scale it up to it's original size? Did I install it wrong?

[patch] Support for kernel 5.18 (Parallel Tools 17.1.4.51567)

invalid@example.com ((GalaxyMaster)) — Thu, 02 Apr 2026 03:29:26 +0000

I am late to the party (did not have time to update my kernel in time), so the attached patch was not created by me, but by somebody else. Thanks goes to @MichelH3 for providing a link. The patch was reviewed, reworked to have conditionals on the kernel version, it applies cleanly to the latest Parallels Tools (at the time of the writing)., and works on my Intel-based VM fine (there are also reports that the patch works for ARM-based version too).

The original patch...

/usr/bin/prlcc causes dead/unclickable areas on screen edge after snapping window

invalid@example.com (IoannisK3) — Sat, 28 Mar 2026 10:38:04 +0000

As the title says, I was confused for a very long time because in Linux (X server only-not wayland) whenever I snapped a window on the screen edge inside the vm, it caused this area to become unclickable. E.g. even if I moved the window, I was not able to click anything on that area!. xprop showed this when inspecting the unclickable area which doesn't seem normal:

└─$ xprop
XdndAware(ATOM) = undefined atom # 0xa240e6ff

Machine Learning with eGPU

invalid@example.com (JacobK7) — Wed, 18 Mar 2026 14:17:07 +0000

I've read that Parallels Desktop supports eGPUs now. Does anyone know if this is an option for machine learning development? I'd like to do TensorFlow development on my MacBook Pro 16" in a Linux virtual machine that's making use of an Nvidia card connected as an eGPU.

Is this possible?

Thanks!

Resolution changes in Debian Trixie

invalid@example.com (walterweide) — Sat, 14 Mar 2026 20:29:01 +0000

iMac M4, macOS 26.3.1, Parallels 26 Pro, Debian 13.3. I changed resolution to full resolution in vm settings.

From time to time resolution in Debian changes to 1024 x 768. I can change it to higher resolutions then. But iMac native resolution is missing from the list of choices. After some time this problem solves without me doing anything.

What can I do?

: Ubuntu terminal receives unexpected Ctrl+C (SIGINT) when dragging windows in Parallels Desktop

invalid@example.com (lincolny) — Mon, 02 Mar 2026 03:35:44 +0000

Hello Parallels Support Team,

I'm seeing a keyboard/input issue in Parallels Desktop on macOS with an Ubuntu 22.04 guest VM. When I drag windows in the Ubuntu GUI, the active terminal session receives an unexpected Ctrl+C, which interrupts the foreground process (SIGINT). This happens without me pressing any keys.

Signal-level confirmation
If I run:

bash
bash -lc 'trap "echo GOT_INT" INT; trap "echo GOT_WINCH" WINCH; echo "ready"; while :; do sleep 1; done'

and...

Unable to install ubuntu, no media found error?

invalid@example.com (PeterH93) — Thu, 26 Feb 2026 10:37:35 +0000

Can someone confirm that ubuntu in fact can be installed on a vm with parallels desktop please?
Would appreciate a step by step help in order to not get the media not found error when it tries to mount it then it just tries to download it and runs out of ram.

The support team at parallels is just a tiny little person with no relevant knowledge whatsoever, because why else is it so hard to get some support???
Anyway, the problem at hand:
I have been running Parallels desktop 17 for some time now, and running a windows machine flawlessly. I recently tried to install the new Ubunu 25.4 ARM with a newly downloaded image. I went through the parallels setup wizard, which inmediately saw the downloaded image. I hit install and got the ubuntu boot...

AI Development Package GPU usage

Hello,

Has anyone here used the Ubuntu VM AI development package? I understand that it includes Ollama pre-installed. Does anyone know if Ollama inside the Ubuntu VM can utilize the Apple silicon GPU?

Thanks,

Ubuntu / Debian VMs Have Performance Degrade Until They Become Unusable

invalid@example.com (PatrickC20) — Thu, 05 Feb 2026 13:26:41 +0000

I run two or three VMs usually, and I always have the same problem. Performance starts out great, but slows over time until the VM becomes completely unusable. Then I have to restart it.

Eventually the length of time I can go between restarts shortens to just a few minutes. When this happens, I backup my home folder, delete the VM, and rebuild it. This restarts the cycle.
When this happens, CPU usage in the VM itself, CPU usage from my Mac, they're both normal. No spikes, nothing weird....
