Hi,

I'm having some issues with my devices on ubuntu 9.04, in particular the keyboard and mouse.

I'm fine if I'm just browsing the net, emails etc, but if I attempt to do anything requiring more sys resources, such as playing a game or doing something with graphics, my mouse freezes.

I'm not hot on linux usage purely with keyboards, but I'm able to get my way around firefox for searching, I've found that the following should do the trick

However, this doesn't exist, what can I do to restart my devices? mouse and keyboard as PS/2

If both fail, I have to switch the machine off at the mains, and I don't think this is a healthy practice

Thanks

Restarting hotplug may or may not work, but I think at most it would be a temporary fix. It seems like your underlying problem is lack of resources.
How much ram do you have, what CPU and graphics card are you using?

athlon xp 3400+
4gb ram
nvidia 7900GS

Certainly not state of the art, but that should still be able to "hold its own" so to speak..

EDIT: My mouse + keyboard are connected via ps/2 ports

For some reason if I run anything more resource hungry than firefox, ie Netbeans IDE, my mouse stops working, the cursor remains. Keyboard is OK

I've tried doing ctrl+alt+backspace, but that doesn't drop me to the console like I'd expect / found from googling..

Tried ctrl+alt+f1 but that just kills the keyboard, so I have to cut the power.

Whats going wrong? I understand its pretty warm (at least it is in here) but I'd expect ubuntu to be a lot more stable than this..
