Need to adjust display settings with ATI Radeon X550 video card


1. My display is not centered on my monitor (Samsung SyncMaster 170N). I need to nudge it about 1/8" to the left.

From the online research I've done, I have a suspicion that I need to edit my xorg.conf file, monitor section, HSkew -- but I don't know for sure. I also haven't figured out how to edit the file - I don't know how to give myself permission to do it.

2. My display is generally sluggish (compared to Windows XP on the same computer). It acts like Windows XP did (same hardware) before I installed the display driver.

BTW, this is my first post in LinuxQuestions.org. I have spent several hours (like 4 or 5) trying to figure this out myself. I'm new to Linux. I have dozens of questions that I could ask (and probably will, eventually), but I'm trying to solve problems in a logical order -- get the hardware working first, then get software working.

My system:
AMD Sempron 3400+; 2GB RAM
Debian Etch (stable)
X.Org X server -- ATI display driver (1:6.6.3-2) is installed (according to Synaptic, but is either not configured correctly or it's the wrong driver)

In case anyone is interested, I never figured this out, but as it turns out, I don't need to any more.

The monitor went dead a few months later; I don't think it was related to my original problem. When I bought a new monitor, the display was centered correctly. It was something about that monitor. Even though I don't have this problem any more, I'm sure somebody somewhere does. He/she is probably frustrated that there isn't any easy way (GUI or CLI) to nudge the display a few pixels in any direction. Maybe there is any easy way, but I couldn't find it after several hours of Googling and asking on LinuxQuestions.org.

I'm well on my way to switching from Windows to Linux. I learn something new just about every day. But, Linux (even Ubuntu 8.10) still frustrates me every day.
