Microsoft Ergonomic 7000 keyboard + mouse lag
- by user115210
I recently bought a new Microsoft Ergonomic 7000 keyboard. I started to use it with my Ubuntu 12.04 and it lags all the time. I try to be more specific:
Even on a minor CPU usage the mouse lags. By minor I mean firefox loading a webpage, or opening an application like conky, gnome-terminal etc.
When higher CPU usage occurs the keyboard is lagging too, but by this I mean it misses my hits, so what I type won't appear later.
What I tried so far (and did not work)?
Disable autosuspend (echo -1 to sys/bus/usb.../autosuspend) and at the same place set level to "on".
I have tried several video drivers: Vesa, radeon, newest catalyst (and catalyst beta too)
When my keyboard and/or mouse lags I tried an other USB keyboard which works perfectly and the same for the mouse. I tried the keyboard and mouse on a different computer with Linux (Ubuntu, Arch, OpenSuse) too, the same problem appears but not on Windows.
I tried to replace the battery sets, and to change channel on the dongle. And also tried to use the dongle from other USB ports. On the same time I am able to use any other wireless mouse.
I changed the XkbModel to "microsoft7000" but it did not solve anything.
About the hardware:
AMD A8 3870K - Radeon HD6550D
8 GB of memory
4 GB of swap (which is almost never used)
