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.
Its sad but linux is still a second class citizen. Nvidea drivers have improved greatly over the years, but it can be still flaky especially newer ones.
Multi moniter support too, it has a history troubled with challenges. Its much much better than it used to be but sometimes there are setups and usecases which have problems. It used to be multiple monitors, just having them as a desktop, was impossible. Nowaday I can daily drive Linux and expect to have a good desktop experience across multiple monitors.
Mindyou, every windows update its a dieroll what breaks for my work surface labtop. Often my display or dock behaviour breaks or my bluetooth, or my networking. Not to excuse the bugs in linux, but to show that even MS on their own hardware have bugs like that. Pcs are hard and even MS can't do it flawlessly.
What you describe as simple multimonitor RDP might actually be a very complex task from a technology and display standpoint.
That being said, it totally sucks having a usecase and finding out that for you have problems getting there. I agree that Linux still has major hurdles for general adoption, (although again, it is so much better than it used to be). Look at it this way: if desktop linux had the same amount of money and development time thrown at it as Windows or MacOS, we'd have a very different experience.
As for tips. I recommend to dualboot. Use MS for your usecases that are not a good experience and use Linux for the other things. Keep checking in with the multiple RDP tech/workflow to see if it works. I did the same thing for years. The only reason I used windows was my games. For other things I used Linux and learned my way around the desktop while doing that. Eventually Proton came along and I could switch entirely.
If you go back a bit further, multi monitor support was just fine. Our office in about 2002 was full of folks running dual ( 19 inch tube! ) monitors running off matrox g400's with xinerama on redhat 6.2 ( might have been 7.0 ). I can't recall that being much trouble at all.
There were even a bunch of good years of the proprietry nvidia drivers, the poor quality is something that I've only really noticed in the last three or so years.
