[Bug 2046798] Re: Ubuntu Wayland does not support 21:9 monitor
The HDMI port on that laptop is only 1.4b so probably cannot support the monitor. Yes please do use USB-C for external monitors if you can. ** Changed in: mutter (Ubuntu) Status: Expired => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2046798 Title: Ubuntu Wayland does not support 21:9 monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2046798/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 2046798] Re: Ubuntu Wayland does not support 21:9 monitor
Hi. Sorry for delayed response. Finally I figured out the issue reason. The subject laptop (Lenovo G15 V3 IAP(82tt)) has i7-1255U. For some weird reason HDMI output cannot render @ 3440x1440, but goes well with 4K. I've attached laptop's USB-C output to monitor's DP input using USB-C->DP cable and all caught up just perfect. So the root cause is the i7-1255U iGfx.

[Bug 2046798] Re: Ubuntu Wayland does not support 21:9 monitor
That's odd because 3440x1440 actually has lower bandwidth requirements (fewer pixels) than 3840x2160. Still, to go above 60Hz you will need both your HDMI cable and your graphics card to be capable of HDMI 2.1, not just 2.0. Please tell us the model of graphics card you are using. If you're just using the integrated graphics of the Intel i7--1255U chip then I'm not sure that can do it with HDMI. DisplayPort looks more certain to work (you may need a USB-C to DisplayPort cable for that). Please also run this so we can see the modes that the kernel driver believes are possible: sudo apt install drm-info drm_info > drminfo.txt and attach the resulting text file here. ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2046798 Title: Ubuntu Wayland does not support 21:9 monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2046798/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

apport information ** Tags added: apport-collected mantic wayland-session ** Description changed: My second monitor attached to HDMI of my Lenovo V15 is DELL S3422DWG and has aspect 21:9 with resolution 3440x1440, with supported resfresh at 100Hz. I could not set native resolution on my second HDMI DELL S3422DWG in any way. I tried cvt, modeset, passing boot parameters to grub, porting EDID from Windows 10 to custom EDID with grub parameters. Every one move ended up with 4k resolution 3840x2160(16:9). And I saw a lot of similar reports on unresolved 21:9 issue on reddit, stackoverflow etc. Kind regards. + --- + ProblemType: Bug + ApportVersion: 2.27.0-0ubuntu5 + Architecture: amd64 + CasperMD5CheckResult: pass + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 23.10 + InstallationDate: Installed on 2023-11-01 (49 days ago) + InstallationMedia: Ubuntu 23.10.1 "Mantic Minotaur" - Release amd64 (20231016.1) + Package: mutter 45.2-0ubuntu1 + PackageArchitecture: amd64 + ProcEnviron: + LANG=ru_RU.UTF-8 + PATH=(custom, no user) + SHELL=/bin/bash + TERM=xterm-256color + XDG_RUNTIME_DIR= + ProcVersionSignature: Ubuntu 6.5.0-14.14-generic 6.5.3 + Tags: mantic wayland-session + Uname: Linux 6.5.0-14-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sudo users + _MarkForUpload: True ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/2046798/+attachment/5730915/+files/Dependencies.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2046798 Title: Ubuntu Wayland does not support 21:9 monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2046798/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
