I have lost my mouse functionality, and I have to work without it on my Ubuntu PC for a couple of days. I am OK with doing my stuffs without it on my computer. But I'm having no good time with web browsing at all. If I want to select a link I have to press tab several times, If I control mouse with Numpad then mouse moves really really slow (and it is useless). So, at the moment I do my stuffs on my PC and do web browsings with my laptop. Is there any way to solve this? I am using Ubuntu 12.10
You should be able to control the acceleration settings of the mouse in the "Mouse Keys" tab of the "Keyboard Preferences" (source):
Settings > Universal Access > Pointing and Clicking > Mouse Keys (disable)
Alternatively, you may be interested in these:
provided you're using Firefox, addons like these might be worth considering:
which I don't use anymore (at least not currently and not in the foreseeable future)
and of course the indispensible (?) keyconfig extension:
which I've been gratefully using for donkey's years.
Good way to learn some keyboard shortcuts search Ubuntu.com for keyboard shortcuts
An other handy option is using any game controller mapped with xboxdrv to your convenience.
