I can't use Firefox, too. I connect from my Android smartphone and Android TV via VNC to be able to use Linux (and Firefox). For the smartphone I use RealVNC's VNC Viewer, and for the TV I use bVNC free. On the other end I use tigervnc server. I don't know if there is a new GPU out there that makes Linux and all applications usable when directly connected (HDMI etc.). If I did I think I would buy a new PC.

    KM Which Linux-distro do you use? I noticed big differences in eye comfort between e.g. Ubuntu and Fedora.

    Guess at the end it is probably only a setting somewhere but I don't know where and what that setting is.

        deepflame Fedora uses Wayland as display server by default, and Ubuntu uses Xorg. I think that may be the difference you are looking for. Can you try Wayland on Ubuntu and see if you notice any difference from default Ubuntu?

            deepflame I don't know what to use anymore when directly connected to a display. No matter what, there's always that small Linux eye strain that accumulates over time. That's why I use VNC. That way whatever would cause the eye strain on a directly connected display won't happen. Provided the VNC client itself is OK to look at.

            Maybe there are hardware/software combinations that work nowadays, but I don't feel like buying new graphics cards which require new PC components over and over again anymore just to find out it was expensive but didn't help.

            I remember on Ubuntu Mate it helped to turn off the desktop composition. But it just helped, it didn't fix the eye strain.

            I think running a trusty old machine (could be even Windows XP or earlier) and then connecting via VNC to a new PC is an option - if you don't need multimedia.

              murateroglu yes, good point. Was thinking about this as well. May be worth a try. Not sure when I have time to do this though.

                murateroglu Ok, tried Ubuntu 20.04 with current kernel ( 5.4 ). On Wayland it seems a bit better than X-Org but I cannot imagine myself working with this setup for hours. There is still some irritation in my eyes.
                Fedora 32 works currently very well for me. Can use it average 10 hours a day for the whole week without issues ( using the setup described above ).

                    deepflame Fedora 32 uses the 5.6 kernel. Fedora 33 coming out on Oct 20th will be the 5.8 kernel. I am not currently using Linux, but I do still follow the news and I see a lot of video and power driver changes went in for 5.9 and 5.10, what would be an interesting experiment to try on that Ubuntu 20.04 (using 5.4 kernel), would be to take the 5.10 release candidate, and actually compile it for your hardware in the 20.04 environment and then evaluate how it now compares to the Fedora 32 setup you have. Now, I recognize you're unlikely to do this because it's a hassle and you already have something working, but it would still be an interesting experiment.

                        Sunspark Fedora 32 uses the 5.6 kernel

                        I am curerntly using 5.8 , 5.6 and 5.4 were also fine as far as I can recall.

                        True, and I may do it if I was 20 years younger without children 🙂

                        Hope that others that have to use Linux for whatever reason might find it useful and try it for themselves.
                        Will definitely follow along and see how things progress.
