Blog post with the same info, for people who don't like watching videos.

kde has a screen tearing bug for games on a gsync monitor

You mean on Wayland? I play a lot of games, so I haven't dared try it

No worries, any attempt to help solve this is welcome :)

I meant I use the KDE colour management settings to set the calibrated icc profiles for each display. I guess it uses colord under the hood, since restarting the service reloads the profiles. Or did you mean some other kind of display profile?

Thanks! I'll give it a try. Never used it before but it sounds interesting

Colour management/correction is done by the computer without involving the monitor afaik.

But I have a suspicion what might be causing your issue.. Computers can indeed control monitor settings such as brightness and power on/off through something which I believe is called DDC/CI (in case you wanna search for more information). When I bought a new Dell monitor I got an issue where it would randomly change brightness every now and then. I have my Linux PC hooked up to 2 monitors, and my work Windows laptop also connected to one of them. So while I was working, my own PC would think that I was idle and dimmed the screens. However, unlike my old monitors, the Dell would accept DDC/CI commands on all connections, not only the selected one. I just turned off monitor dimming in KDE control panel power settings as a workaround, and let it turn the monitor signal off immediately on inactivity.

While researching the issue, I also came across multiple posts by people having problems with Dell monitors randomly changing brightness, with only one computer connected, so it could also be that.. Dell has a reset procedure which they claim should fix it, but it's different for pretty much every model, so you'll have to find the one for yours, in case you have a Dell monitor. Some people wrote that it didn't work and they had to RMA the monitors.

Xorg, but it has worked without issues on Fedora for over a year, and it also worked on Xubuntu before that :/

I know nvidia-settings messes up the colors if I open its GUI, but I haven't found any other program which does so. I do use nvidia-settings from a script when power limiting + overclocking my GPU, but I have verified that it doesn't mess with the colours, and I've also had it for almost a year so it's not new.

I only have a Vive, but according to reddit this how you do it :) https://www.reddit.com/r/ValveIndex/comments/c8wvft/how_to_reset_hmd_back_to_factory_firmware/

And just brainstorming here, I think I've had problems in the past where I had multiple high resolution + high framerate monitors, though it might've been on my work computer where I had a docking station.. What other monitors are you using? Have you tried lower framerates? My last graphics card was a GTX1080 which is similar to yours, but I don't remember if that one had any peculiarities with VR. Back then I dual booted Windows for VR since it didn't work well enough on Linux

Any possibility to verify that the headset's power adapter is working? E.g. multimeter

I saw someone suggesting a headset firmware reset for this issue, but others are saying they had to RMA their headset when they got solid red lights on it :(

When you say you got a new cable, you mean an original tether cable, which is connected directly to the graphics card without adapters or extension cables?

Also, are you using Nvidia's closed source drivers or Nouveau?

Use whatever you like :) I tried VSCode at work for a few months but it felt quite lacking when working with larger C++ projects. Switched to CLion instead and it felt like it was faster, understood C++ much better, and made it easier to work in multiple files simultaneously. But I could see myseslf using VSCode for some small hobby project, especially if it's C#

So it's supposed to be 15 hours/month included with your premium subscription? Since I'm not familiar with how Spotify audio books work, I thought you meant that you had a free account and was allowed to listen 15 hours to books that would be included/unlimited with a premium subscription. Contact support if it ate through your monthly credits faster that it should. If you're a paying customer supports are usually quite helpful.

Don't know if Fedora has any similar easy way of tracking vulnerabilities

Fortunately I dislike Windows so much that I'm willing to spend a few weekends helping someone switch to Linux, especially if it's my wife :D I'm also realizing I might've skipped a step in the conversation since the person I replied to was talking about Ubuntu, and it's possible that at least some of those problems were specific to Xfce. In my mind I reasoned "I used to think that Xubuntu would be a solid recommendation for a beginner since I had a good experience with it in the past", and it sounded like others were saying similar things about Ubuntu. Since I discovered that Xubuntu now had a lot of non-trivial issues I had to deal with, I was kind of thinking that it might be the same for vanilla Ubuntu.. Or not, it might still be easy to use and a plug-n-play experience for beginners :)

Small disclaimer: I'm not claiming all these issues can be said to be 100% Ubuntu's fault, but if recommending a distro to someone who wants to try Linux for the first time they probably won't care about anything other than the compound experience. I used Xubuntu for many years and remembered it as very stable and the vast majority of things being easy and working out of the box, which is why I was so surprised that I had to spend hours troubleshooting various things that I never had problems with previously.

Some issues and annoyances I remember off the top of my head:

Unable to wake computer after monitor turning off due to inactivity. Happened to all 3 computers which have very different hardware, which seemed a little strange to me. Did some troubleshooting on my wife's desktop PC and IIRC it appeared to be the program which would ask for your password crashed, causing the computer to turn off the monitor signal again. Uninstalled the xfce4-screensaver package and disabled password on resume on her PC which fixed it there, but her netbook needs to have password and I think it still sometimes has this issue (she doesn't use it very often). On the htpc I both uninstalled xfce4-screensaver and disabled all monitor power saving, but recently it has started turning off the monitor signal after inactivity anyway. At least it always wakes up from this state.

However, the htpc sometimes fails to wake up the monitor/tv after hibernate. The computer wakes up but the monitor doesn't, and the only solution I know is the following procedure: Wake the computer up, press ctrl-alt-f1 to switch to a different vtty, press the keyboard shortcut to hibernate the computer, wake it up again, press ctrl-alt-f6 to switch back to the graphical desktop. For some reason that works..

Every time the htpc wakes up from hibernate there's a notification saying something about the computer being reconnected to the network. There's a button on the popup for "don't notify me about this again" but it makes no difference, the popups keep coming. Can ofc. be disabled entirely from some other settings, but it's not working as expected.

Watching movies in Kodi doesn't work. It starts playing it without sound, then it begins to stutter after about 10 seconds and it gets worse until Kodi freezes entirely. Haven't had time to properly debug it, but it worked just fine on Arch (which I wouldn't recommend to a beginner for other reasons :)) which the previous htpc had. Instead we use VLC for the time being.

We watch various series on youtube and dropout.tv so we have a browser tab permanently open for each, often with longer episodes paused in the middle. About once per month there's a popup telling us that we must close the web browser so that snap can update it. The popups don't time out, and need to be clicked to go away. If you click to ignore it too many times it will forcibly close eventually. Occasionally this causes the web sites to forget what we were watching, and it can take a bit of time to find out where you were in a 3 hour D&D actual play. Probably snaps working as intended but both of us find it annoying.

Over all our Brother laser jet + scanner is great with Linux, but I had to spend a few hours to get all features working on my wife's PC while it was pretty much plug-n-play on my current install of Fedora KDE.

Wife's PC had issues with monitors losing their relative position and orientation. It might've been triggered when one of the cables glitched a bit, and it doesn't happen now that they're screwed in properly, but I think the OS ought to remember the configuration better. It also moved the monitors so they weren't adjacent, which made the mouse pointer behave very weirdly when moved between then until she rearranged them in the settings.

There were some other things that I'm not able to recall right now too, nothing too serious for someone with Linux experience. My wife used Ubuntu at university so she's not computer illiterate, but I don't think she would've had the time and energy to spend hours troubleshooting issues, searching online and digging around in config files, so she probably would've switched back to Windows since it mostly worked for her.

It used to be at least, but I'm not so sure that it still is. I've been using Linux full time for over a decade, mostly Xubuntu but also other distros and vanilla Ubuntu. Last year my wife decided that she wanted to ditch Windows for good so we installed Xubuntu on her pc, her netbook and our new htpc, and I was surprised that we ran into so many different issues. I could solve some of them but I think it would be much more difficult for a first time Linux user, and potentially give them a bad first impression of Linux OS:es.

I have a stupid one, but far from funny.. I've been using and building computers for a very long time so I'm far from a noob, but I'm still quite cautious, bordering on paranoid, so I like to unplug all other drives when re/installing an OS just to avoid stupid mistakes. I go through the installer on the livecd, there's only one drive to choose from so I don't think much about it, select that it should erase everything, I set up the new partition structure, and start the process. After about a minute I begin wondering "why is it taking so long?", and "what is that ticking noise? SSDs shouldn't be making any sounds when written to", when I realize that I had unplugged the wrong drives and that I was currently overwriting my main storage drive. Of course I had backups of the most important things like photos and code, though not really synced for a couple of months so I lost some stuff permanently.

I guess you'd need to find him first if you want to fight him? I think TempleOS is also FOSS in case you want to find god without fighting him.

I've been using Intel NUCs, even though they have a lot of issues and start failing after about 3 years of heavy use. Previously used Kodi on Arch, but with the latest NUC I decided to go with Xubuntu and for some reason video playback doesn't work in Kodi now. So instead I just use VLC media player for TV/movies and a web browser for everything else. Got a Logitech K400 Plus wireless keyboard which makes it easy to control the computer from the couch.

I work for a large IT company so we've had numerous such training courses, but then they use third party services for time reporting, manager evaluation, cloud services, personal finance advice, etc. so I regularly get emails with links to domains that I've never heard about that I'm supposed to trust..
