I have dual monitors on this laptop and endless problems with them and KDE.
Tried to load latest fglrx non-free driver but it would not install.
I understand it can be installed nonetheless, but have not tried it yet
Trouble I get:
1) KDE preview does not show up on main LVS monitor but on additional VGA, causing continuous black spots on screen, I am afraid to hover mouse over programs minimized in Tray Manager.
2) Screensaver only starts on additional monitor, main LVS just shuts off display, I get error messages like: screensaver daemon is not running in display 0.
I don't have these problems in computers running with just one monitor.
I didn't have these issues in GNOME, a couple years back when I was running Linux Mint.

I have only experience with nvidia cards but suspect you are on the right trail - fart around with the drivers. In my case the nouveau (open source) driver worked flawlessly with systemsettings while the proprietary one does not handshake with xrandr so that I had to use the nvidia gui...

Nouveau driver is installed, but not active because it is not for ATI Radeon cards.
I might as well purge it, it is for nvidia.
My only option is the fglrx non-free driver, could try installing that, but it does not support my card.
I have been dealing with these blackouts for months now, so I would rather disable the preview when hovering over the Tray Manager.
Know how to do this?
This won't solve the screensaver issue, in spite that my primary monitor is set to LVDS, it only works in the additional VGA monitor.

I'm using an ATI 4870 with the proprietary driver 12.04 also with a dual monitor setup.

No issues whatsoever. Everything works as expected, I have a large desktop, and even suspend/resume works just fine.

So there might be another issue on your setup.

Just follow the wiki: http://wiki.cchtml.com/index.php/Catego ... umentation and make sure that you first clean the system from all drivers.

Thanks for answer, my setup is different, this is a relatively old laptop with a card not supported by latest drivers.
I have tried removing drivers like nouveau, but it would ask to remove other stuff like xserver-xorg-video-all.
I will continue trying, backing up the whole system disk first, I have two disks.
Will post here the solution if successful.
