I opened a similar bug and @vanvugt advised me to come here. I read everything and will try the PPA if need be.
But I'm using a driver that nobody mentioned, which was selected by Dell who assembled the machine and installed the OS. On Nvidia driver section, I'm using "Set the power ondemand mode by default from oem-fix-gfx-nvidia-ondemandmode". I also have drives 535 and 470 available in the menu, but when I install them, my default setting disappears. I had to fully reinstall the OS to get it back. Nvidia themselves advise on their download page to not necessarily use their proprietary drivers on some Linux distribs, so I stuck with my default driver. Will the PPA and the mutter downgrade be of use with this default setting ? Also, installing proprietary pilot from the Software & update menu raised an error, so I aborted the process. I'm running : - Ubuntu 22.4.04 LTS - GNOME 42.9 (latest official update) - X11 - NVIDIA T400 4GB Thank you -- 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/2059847 Title: Input lag or freezes on Nvidia desktops with X11 after logging "MetaSyncRing: Sync object is not ready -- were events handled properly?"
