The mouse cursor freezes for about half a second, and occasionally the system audio also cuts out briefly. This happens irregularly but repeatedly. The issue started after updating to Linux 7.0.0‑14‑generic. Around the same time, linux‑firmware was also updated, so I cannot determine which change might be responsible. On my laptop (Intel + Nvidia) I cannot reproduce the issue, but another user with AMD hardware reported similar symptoms on Discourse. Affected hardware: · CPU: AMD Ryzen 5 9600X (12) @ 5.49 GHz · GPU: AMD Radeon RX 9060 XT · OS: Ubuntu 26.04 Observed behaviour: · Mouse cursor freezes for ~0.5 seconds (“micro‑stutter”). · Occasional short audio dropouts. · I have not noticed the issue while gaming, although another user claims it also happens there. I would appreciate guidance on additional tools or diagnostics that could help identify the root cause. At the moment, the only evidence I can provide is the observed behaviour described above.

The secondary interface (bInterfaceNumber 01, event3) generates conflicting and garbled escape sequences that interfere with events from the primary interface. Symptoms observed after upgrading to Ubuntu 26.04 LTS (kernel 7.0.0-15-generic; actually Kubuntu, upgrade was via `do-release-upgrade` so was not a fresh install; using the default Wayland, not X11): - Home key triggers ^[[3~ (Delete escape sequence) instead of moving to start of line/list - Right-shift key not recognised (libinput reports keycode -1) - End key works correctly on the primary interface but event3 also fires conflicting sequences Diagnosis: Running `sudo libinput debug-events /dev/input/event3` while pressing Home, End, and modifier keys produced raw escape sequences (^[[H, ^[[F, ^[[D, ^[[C etc.) confirming that event3 is sending its own independent, conflicting key events. The primary interface (event2) correctly reports KEY_HOME (102) and KEY_END (107), but KEY_HOME is tagged with ^[[3~ due to interference from event3. Workaround: Prior to troubleshooting with Claude.ai I `sudo apt install`-ed `libinput-tools`, and `--reinstall` was done for `udev` and for `kglobalacceld`. The ultimate fix was then creating the following udev rule resolves the issue by telling libinput to ignore the secondary interface: File: /etc/udev/rules.d/99-g213-fix.rules ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c336", KERNEL=="event*", ATTRS{bInterfaceNumber}=="01", ENV{LIBINPUT_IGNORE_DEVICE}="1" After `sudo udevadm control --reload` and unplug then replug of the keyboard, all keys work correctly.

Matching subscriptions: Bgg, Bmail, Nb https://bugs.launchpad.net/bugs/2152810 Title: Logitech G213 keyboard (046d:c336) secondary HID interface causes garbled key events — Home acts as Delete, right-shift unresponsive Status in linux package in Ubuntu: New Bug description: The Logitech Gaming Keyboard G213 (USB ID 046d:c336) exposes two HID interfaces, both registered as keyboard input devices (event2 and event3 / input0 and input1). The secondary interface (bInterfaceNumber 01, event3) generates conflicting and garbled escape sequences that interfere with events from the primary interface. Symptoms observed after upgrading to Ubuntu 26.04 LTS (kernel 7.0.0-15-generic; actually Kubuntu, upgrade was via `do-release-upgrade` so was not a fresh install; using the default Wayland, not X11): - Home key triggers ^[[3~ (Delete escape sequence) instead of moving to start of line/list - Right-shift key not recognised (libinput reports keycode -1) - End key works correctly on the primary interface but event3 also fires conflicting sequences Diagnosis: Running `sudo libinput debug-events /dev/input/event3` while pressing Home, End, and modifier keys produced raw escape sequences (^[[H, ^[[F, ^[[D, ^[[C etc.) confirming that event3 is sending its own independent, conflicting key events. The primary interface (event2) correctly reports KEY_HOME (102) and KEY_END (107), but KEY_HOME is tagged with ^[[3~ due to interference from event3. Workaround: Prior to troubleshooting with Claude.ai I `sudo apt install`-ed `libinput-tools`, and `--reinstall` was done for `udev` and for `kglobalacceld`. The ultimate fix was then creating the following udev rule resolves the issue by telling libinput to ignore the secondary interface: File: /etc/udev/rules.d/99-g213-fix.rules ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c336", KERNEL=="event*", ATTRS{bInterfaceNumber}=="01", ENV{LIBINPUT_IGNORE_DEVICE}="1" After `sudo udevadm control --reload` and unplug then replug of the keyboard, all keys work correctly. According to Claude.ai, a proper fix would be "a hwdb entry or HID quirk for 046d:c336 to suppress or correctly handle the secondary interface, so that G213 users are not affected on clean installs or upgrades".
