I can confirm that I have experienced a similar symptom (or worse than the above description). I also upgraded to Ubuntu 9.10 from 9.04, and keyboard and mouse became something that cannot be tolerated - e.g., unresponsive keyboard strokes, especially when I type fast, jumping mouse points here and there, and very sluggish application startup (it looks like hang about a sec, and then come up). This happens virtually all the times (with no heavy application is in use).
The machine has dual AMD Opteron 246 with 2GB RAM. It is running Ubuntu 9.10 amd64 server edition (2.6.31-14-server). -- Mouse and Keyboard stuttering/unresponsive - results in some lost key strokes https://bugs.launchpad.net/bugs/480644 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
