From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've been an IT professional for 20 years now, but I've mainly dealt with Windows. I've worked with Linux servers through out the years, but never had Linux as a daily driver. And I decided it was time to change. I only had 2 requirements. One, I need to be able to use my Nvidia 3080 ti for local LLM and I need to be able to RDP with multiple screens to my work laptop running Windows 10.

My hope was to be able to get this all working and create some articles on how I did it to hopefully inspire/guide others. Unfortunately, I was not successful.

I started out with Ubuntu 22.04 and I could not get the live CD to boot. After some searching, I figured out I had to go in a turn off ACPI in boot loader. After that I was able to install Ubuntu side by side with Windows 11, but the boot loader errored out at the end of the install and Ubuntu would not boot.

Okay, back into Windows to download the boot loader fixer and boot to that. Alright, I'm finally able to get into Ubuntu, but I only have 1 of my 4 monitors working. Install the NVIDIA-SMI and reboot. All my monitors work now, but my network card is now broken.

Follow instructions on my phone to reinstall the linux-modules-extra package. Back into Windows to download that because, you know, no network connections. Reinstall the package, it doesn't work. Go into advanced recovery, try restoring packages, nothing is working. I can either get my monitors to work or my network card. Never both at the same time.

I give up and decide it's time to try out Fedora. The install process is much smoother. I boot up 3 of 4 monitors work. I find a great post on installing Nvidia drivers and CUDA. After doing that and rebooting, I have all 4 monitors and networking, woohoo!

Now, let's test RDP. Install FreeRDP run with /multimon, and the screen for each remote window is shifted 1/3 of the way to the left. Strange. Do a little looking online, find an Issue on GitHub about how it is based on the primary monitor. Long story short, I can't use multiple monitor RDP because I have different resolution monitors and they are stacked 2x2 instead of all in a row. Trust me I tried every combination I could think of.

Someone suggested using the nightly build because they have been working on this issue. Okay, I try that out and it fails to install because of a missing dependency. Apparently, there is a pull request from December to fix this on Fedora installs, but it hasn't been merged. So, I would need to compile that specific branch myself.

At this point, I'm just so sick of every little thing being a huge struggle, I reboot and go back into Windows. I still have Fedora on there, but who would have thought something that sounds as simple as wanting to RDP across 4 monitors would be so damn difficult.

I'm not saying any of this to bag on Linux. It's more of a discussion topic on, yes, I agree that there needs to be more adoption on Linux, but if someone with 20 years of IT experience gets this feed up with it, imagine how your average user would feel.

Of course if anyone has any recommendation on getting my RDP working, I'm all ears on that too.

Bummer! Sounds like a pain in the ass.

I wish I had a suggestion for you, but I only use two monitors and all of my work is ssh, no RDP needed.

I am a long time Linux user but even I am struggling recently as I have finally started working towards migrating my last windows machine ( strictly for gaming ) over to Linux with a windows partition for the one off chance I need to play on windows still. Currently only 1.5 of my monitors work ( my left monitor top half is black. ) It is fine in post, bios and windows but not in my fedora distro. Also, my performance tanked even though I can see my GPU is working as intended. My high refresh monitor is also not playing nice and ghosting all over the place, unlike in windows where there is only standard tearing when there is a frame rate mismatch.

Fortunately for me, I like tinkering and solving these issues, but I can imagine for someone wanting to avoid messing with their equipment it is probably more of a headache than a challenge. But I have personally always been of the mindset of using the tool that works best for you, with the exception of any moral considerations you may have. (I am just not a fan of windows or apple as a company.)

Good luck with your issue and I hope you find a resolution, but if not, I would just use what works.

Sad storry dude. I am running POPOS with gtx1060 as my daily driver for a year now. I used to have 3 monitors, but have 2 atm. Im using rustdesk (tried more apps and still looking for the best one) to connect to my office PC (windows, single monitor) and the other way around. Everything works great, but I need few apps that are windows only (main reason I use remote desktop). Other than that, cant play few games on linux, but i dont care about games that much. I was sure Ill have to go back to windows, but never happened

Long story short, I can’t use multiple monitor RDP because I have different resolution monitors and they are stacked 2x2 instead of all in a row.

Did you try setting them up as one big display across all four, instead of four little ones? I think that's something you can do.

Does the multi-mon RDP thing work from a Windows client too? I'd be surprised if it did, Windows' multi-monitor support is fairly lacking in my experience too.

Sound like fun 🙃 frustrating fun, but hopefully you get something that works when you come back to it. Unusual setups always pay the price.

I would suggest trying a remote desktop solution other than rdp... Although I can see how that may not work since it would involve installing software on your work machine.
