I notice that when installing EOS I can check multiple DE’s and it will let me. I’ve never tried, but can you install multiple DE’s and login to either at login time? I see complications because KDE uses sddm and Cinnamon uses lightdm, and gnome uses gdm.
Maybe using a DE with a window manager like i3 would be possible?
It is absolutely not recommended to install more than one desktop for the same user.
Though you may create another user for each other desktop and never log in to a desktop as another user used with another desktop.
This is what I learnt from the experts here.
The experts her might say better not install more than one desktop anyway. I hope they comment on this.
But just out of curiosity, why you need several desktops?
the reason for multiple DE’s is to test issues. For example I’ve recently had problem where Google Chrome could not play Youtube videos at 1080P on the Cinnamon DE but could play them with Firefox. No issues with Gnome on the same hardware. I’ve also had freezing videos with multiple apps on Plasma (X11)
on EOS, but not Gnome EOS (Wayland).
It doesn’t matter which Distro I use there will be video issues with certain apps with certain DE’s.
I’ve also found that EOS-XFCE4 can’t do 200% scaling on my 4K TV so I can’t use that.
I guess if everything I tried worked, life would be boring. I’d need a new hobby.
I was using KDE Plasma on EOS when I started having my video Freeze up problem. See issue freeze up issue
It might be worth a new install of EOS -KDE and see if I still have the problem. It might be safe to include i3 as well so I can test the same applications without the overhead of KDE to see what’s going on. I did get it working with EOS Cinnamon fine.
Re boredom: I might be banned from here for trying to divert you towards playing with another Arch descendant as well: Arco-extended
It facilitates changing DE-s/WM-s by backing up .config in Arch Tweaks Tools
This I think may be a good start.
Then you can list any problems you have and sort it out.
If I were you I would install only KDE Plasma.
Just curious about your machine. My humble knowledge you may have problems if your machine is too old or too new. Your issues might be because of not enough RAM? I believe 8 GB would be sufficient, less can be a bit problematic.
I’ve installed EOS XFCE4 on a old Macbook Pro in the past and it works great there and I’ve used it on a Raspberry Pi 4 with good results, but on my Den PC which is connected to a Sony X90CK 65" 4K TV XFCE is too big for the screen when I select Scaling 200%. With KDE, Cinnamon, and Gnome It defaults to 3840x2160 and I use 200% to make the DE function as 1080 but allows UHD playback in video applications. The scalling makes the taskbar/panel slide off the screen partially
I did install KDE Plasma and also checked the box for i3.
The Default DE on the first login was KDE and it’s working fine. I tested playing a 1080P video on Youtube and it didn’t freeze up with in the 30 minutes of that video and I built Mythtv and playing Live OTA TV for extended time also didn’t freeze as it did a few weeks ago. So maybe this is fixes.
I did try to login to the i3 session and It would need the display configured before I could use it, so all I did was logout and go back to KDE and do all the stuff I mentioned above
I personally wouldn’t have done that. I would only keep KDE Plasma.
I see your hardware is more than perfect and you have enough RAM.
I wonder if you really need the i3?
Maybe another fresh install without it would be better?
If I’m in your place I would do a fresh install with KDE Plasma only, (my personal taste and thinking), better than uninstalling i3 or keeping it installed and not used.
I guess and hope everything is working OK now?
It is up to you of course.
XFCE handles the scaling ‘backwards’ compared to most DE
s (no idea why). Go on in there, and try Custom 50%, and see how it fits. Here’s my secondary monitor at 1.5 - but .5 (or whatever you like ) would work too.
Of course, it is possible to have multiple desktop environments side by side, but it is not recommended, rather only for the bravest, those who do not shy away from putting up with minor conflicts in return.
