ckosloff@papimalo:~$ inxi -G
Graphics:  Card: Advanced Micro Devices [AMD] nee ATI Radeon XPRESS 200M 5955 (PCIE)
           X.Org: 1.12.4 drivers: radeon (unloaded: fbdev,vesa) Resolution: 1280x1024@60.0hz, 1024x768@59.9hz
           GLX Renderer: Gallium 0.4 on ATI RS480 GLX Version: 2.1 Mesa 8.0.5

I have been having problems with graphics for a long time on this computer.
I have an external VGA monitor plugged into this laptop, I do need the dual monitor setup, but wheezy-kde doesn't seem to handle it well, I get blackouts instead of previews, main screen does not come back after power save although suspend session is disabled, etc.
Am I loading the correct driver?
This does not happen on other computers with only one monitor.

Just out of curiousity, did jesse/kde fix this issue?

radeon xorg has known issues with power management, sometimes they claim they are resolved in latest xorg driver or kernel kms stuff for radeon but I don't track amd issues much anymore.

Yes, but I don't know exactly how.
What I did is simply backup my .mozilla in home, in order to save passwords and configs for sites I use, and hose everything else.
I used the netinst CD for testing, not the stable one, cause I didn't want to go through 4 hours of upgrades.
Loaded everything except desktop environment, then everything else via smxi, with external monitor UNPLUGGED, this step is very important if you don't want your external monitor fused and set up as screen O and laptop monitor LVDS set as clone.
Once this happens it is impossible to reverse course, for some obscure reason, tried everything, xorg.conf, xrandr, arandr, etc.
Setting monitors in the desired order with xrandr caused terrible system crashes.
I gave up and hosed everything, after everything done plugged in external monitor, KDE tool (Display applet under System Settings), detected it immediately, I configured everything without a glitch and saved default config.
End result is a much better resolution (set to auto for each monitor), crisper graphics, preview works great (it never did before, I was getting blackouts), more responsive system overall.
Dual monitor setup is still a bitch with Linux, but it's getting better.
