Hi Stefan,
Thank you for reporting this mouse lag issue. I've investigated your
report and found something important that needs clarification.
You mentioned you're running Ubuntu 24.04.4 LTS with kernel
6.17.0-14-generic. However, according to Ubuntu's official package
repositories, kernel 6.17.0-14 is NOT available for Ubuntu 24.04 (Noble
Numbat) on x86_64 architecture.
Kernel 6.17.0-14 is only available in:
- Ubuntu 25.10 (Questing Quokka) - an interim release
- Ubuntu 26.04 (Resolute Raccoon) - a future LTS release
- riscv64 architecture in Ubuntu 24.04 updates
This discrepancy suggests one of the following:
1. You may have manually installed a kernel from a different Ubuntu release
2. There might be confusion about your Ubuntu version
3. You could be using an unofficial kernel source
Could you please verify:
- Your exact Ubuntu version (run: `lsb_release -a`)
- Your architecture (run: `uname -m`)
- Where the kernel 6.17.0-14 came from (did you install it manually, or did Ubuntu offer it as an update?)
I did find multiple reports online about mouse cursor offset/hotspot
issues specifically with kernel 6.17.0-14 in X11 sessions. If you're
indeed running this kernel, there appears to be a known issue affecting
mouse input handling.
Thank you.

Title:
Mouse lags at least since previous update (6.17.0-14-generic)
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have Ubuntu Ubuntu 24.04.4 LTS with Linux 6.17.0-14-generic now.
Even after a fresh reboot, Ubuntu shows lags in mouse movement. I have no special mouse (gentix 4KCherry). The lags show by stuttering curser (still fast, but slow enough to be seen).
Actions to provoke misbehaviour (no special preconditions, just on Ubuntu desktop)
1. moved my mouse to one direction
2. stopping to move
3. waiting some seconds (optional; no matter how many)
last step:
4. THEN moving to the opposite direction
Seen misbehaviour:
- even during step 1, the mouse stutters
- on step 4, the cursor once appears in the old direction. This is unexcepted and makes no sense for me. The next mouse cursor views follow the direction, still in the same stuttering kind. What could be the issue?
Further info on my environment (partially on proposal by AI, so decide yourself if you need it):
uname -a
Linux a 6.17.0-14-generic #14~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Jan 15 15:52:10 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
I'm using Wayland (no difference on xorg)
