Linux On My Samsung

When i use the laptop without ac power mouse works perfectly, but when using battery, after 5 seconds of inactivity or so, the mouse does not respond instantly, i have to move it like 5 seconds or so... it happened with a microsoft usb wireless and now i have a brand new logitech with usb nano receiver. same problem!
what can i do?
thanks.

pd: using ubuntu 10.10 on a Samsung R480 laptop.

As I understand no problem when laptop works from power supply? Try to delete /etc/pm/power.d/samsung-tools_usb-autosuspend file. It helped me with the same issue.

Best regards,

seems it worked, but, what does this file do? and why there isn't any option to disable usb suspension?

Looks like Voria included Usb-suspend function in Samsung tool for long battery life (there was thread somewhere here). But I have the same pbm as you with my usb mouse. I have to delete this file after each samsung-tools or kernel (not sure which one) update.

Best regards,

Same probleme here with a VX Nano.

Thanks for the tip

so is samsung-tools going to be updated for natty (ubuntu 11.04)? I have the problem about USB mouse sleeping_each_2_seconds after suspend/resume cycle. I did to make it not executable, but I want to know that my power resources are used optimally... Maybe there is an option to tweak that 2 seconds time to something more reasonable - let's say, 60 seconds? Where can I do that?

Edit /etc/pm/power/d/samsung-tools_usb-autosuspend and change "2" in the line to the number of seconds you want.
