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.
I read the first paragraph and saw your prerequisites included working with nvidia.
That is a non-starter, right there. You can blame Linux for a whole lot of little flaws, but most of the blame should go to your hardware vendor for providing shitty support for Linux.
Popos has out-of-the-box nvidia support that works great
Works with CUDA and RDPing on a 2x2 monitor grid?
System76 (who makes popos) has their own CUDA repo for their NVIDIA implementation, but I don’t think it’s installed by default. So there’s a tweaked version to work on popos, but I’ve never tried it. From some cursory googling, it doesn’t seem to be too complicated to set up.
Yeah it's really weird. I have done what OP has done for a while now on an Nvidia GPU and Pop!_OS with KDE and have had 0 issues. I don't use a 2x2 grid though. Can that really be the issue?
