Mint didn't work on my t510 laptop (I bought the laptop refurbish three months ago after my lenovo t4xx die after 10 years of usage). I reinstalled it with kubuntu 12.10 and the volume buttons doesn't work nor some of the fn+command keys. Sometime the touchpad just die and I have to restart the computer if I really want the touchpad (I use vim+tmux to dev so I don't need the touchpad unless I want to surf the web). edit: As for what was wrong with mint. After Nvidia's driver update sleep wouldn't work, it would sleep forever like sleeping beauty unless you hold down the power button for several second to turn the laptop off and reboot.
