View Full Version : [ubuntu] full HD monitor not working in MM

November 29th, 2010, 06:59 PM
Hardware :
monitor BenQ G2222HDL
notebook Acer Extensa 5620G with Mobility RadeOn HD 2400 XT (proprietary FGLRX drivers)

Problem :
In System>Pref.>Monitors I only see one monitor even though I can see the desktop on the second monitor and move the cursor to it (but it's only in the resolution of my laptop monitor). I click "detect monitors", but nothing happens.
At first I saw an "unknown monitor", but I couldn't set it up normally.
Thru System>Pref.>Catalyst control center I can set it up (it worked for like 3 secs), but then the system freezes and I have to hard-reset it.

It works fine in Windows 7.

Please help me.
