SA,
I have HP probook 4520s Core i5 it comes with SUSE enterprise 11 and everything working but when I removed it and installed Ubuntu I got I problems with drivers nothing working
Graphic is ATI Radeon HD 6370.. ubuntu hardware found driver for 6300M and I installed it but I still have problem it is wrong driver
synaptic toucpad right click isn't working also turn on/off key isn't working . I tried synaptiks but it didn't solve anything
I've problem with wireless /bluetooth the keyboard wifi key led becomes crazy . its light keeps going on and off continuously ( red -white - red - white .......)
I tried fedora 15 and I got the same problems I found drivers on hp for SUSE enterprise 11 I tried to use synaptic driver but it didn't
