Resolution and refresh rate are managed in Settings\Display but I find playing games creates remarkable eye-strain which leads to blurred vision and I fear other vision problems longer term. I've found multiple accounts of people running into this and returning to Windows. I don't see an alternative given the seriousness of my vision problems. I've uninstalled my games and have a dual boot setup to support gaming, but the ENTIRE reasoning for this is protecting my eyes from Ubuntu's video implementation. Here is one account of someone dealing with this problem: https://www.reddit.com/r/linuxquestions/comments/180fav0/linux_is_killing_my_eyes_to_the_point_im_back_on/ Trying to keep up with Nvidia is quite the task, but given Nvidia's place in the GPU market, it has to be done. Here are settings in nvidia-settings that are not supported in Settings\Display I've tried fiddling with to reduce eye strain: XScreen0\OpenGL Settings\Image Settings --> High Quality XScreen0\Antialias Settings\ --> Enable FXAA XScreen0\Antialias Settings\Anisotropic Filtering --> Override Application Settings\16x GPU0(Nvidia RTX4090)\DP-4(Samsung LS49AG95)\Controls\Color Space --> YCbCr444 [does not change from RGB] Root Cause: beats me. There are so many options and esoteric features involved with GPUs and video performance, I don't have the background to try to uncover what medically is going on, but it's clearly bad. This is a real problem, and the consequences for Linux users are real. Driving home last night I found all street lights had a complex, somewhat pixelated haze around them. Possible Approaches: - Reach out to Nvidia. They have the resources to dig into the medical affects of poor video configurations. Perhaps they would fund an initiative to support this work. - Review the research: ----here is research----- Digital Eye Strain: A Comprehensive Review https://link.springer.com/article/10.1007/s40123-022-00540-9 Management of Digital Eye Strain https://www.tandfonline.com/doi/abs/10.1111/cxo.12798 Eye-related pain induced by visually demanding computer work https://journals.lww.com/optvissci/fulltext/2012/04000/eye_related_pain_induced_by_visually_demanding.13.aspx Image Modification to Reduce Eye Strain https://link.springer.com/chapter/10.1007/978-3-030-88919-7_17 --- ProblemType: Bug ApportVersion: 2.32.0-0ubuntu5.3 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 25.04 InstallationDate: Installed on 2025-04-13 (113 days ago) InstallationMedia: Ubuntu 24.04.2 LTS "Noble Numbat" - Release amd64 (20250215) Package: gnome-shell 48.0-1ubuntu1 PackageArchitecture: amd64 ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcVersionSignature: Ubuntu 6.14.0-27.27-generic 6.14.6 RelatedPackageVersions: mutter-common 48.1-1ubuntu3.1 Tags: plucky Uname: Linux 6.14.0-27-generic x86_64 UpgradeStatus: Upgraded to plucky on 2025-07-27 (8 days ago) UserGroups: adm cdrom dip lpadmin plugdev sudo users _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2119415/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
