Arg. Ubuntu/Mint drove me nuts telling me I cannot do things with my own
system, and SUSE is just as almost working as ever. So, I think I'm going to
give Mandriva a try for a while. I'm using the Mandriva One 2007 live CD,
and all is great except for one minor issue. Everything is fuzzy because my
refresh rates are set out of wack.
It automatically sets them to:
HorizSync 15-94
VertRefresh 24-88
The should be set to:
HorizSync 50.0-65.3
VertRefresh 60.0-75.0
I changed that, but nothing is ever that simple. After restarting X, my
maximum resolution drops from 1650x1080 to 1280x1024 (or somewhere around
there). It looks great (no fuzz) except for the part where it's a tiny
square in the middle of my screen.
Why? Why? Why? Why?
Short (likely) answer is that your video card probably doesn't have
the available bandwidth to drive that resolution at the refresh rate
OR those sync and refresh ranges define a refresh rate that is out of
bounds for the monitor. Remember that when driving an LCD via an
analog connection you virtually always want to drive it at 60hz, the
"higher refresh is better" rule does not apply to LCDs
. The "quick fix" I'd suggest is to _not_ do it by hand and let the
EDID and other automatic monitor magic do it's thing. For example, the
relevant portions of my xorg.conf here at work are:
Section "Device"
Identifier "ATI Technologies, Inc. Radeon Xpress 200 (RS480)"
Driver "radeon"
EndSection
Section "Monitor"
Identifier "SyncMaster"
Option "DPMS"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies, Inc. Radeon Xpress 200 (RS480)"
Monitor "SyncMaster"

That config works perfectly and I'm able to use all the resolutions I
should. I can control the current rez and refresh using XRandR, though
in practice I don't remember the last time I took it out of
[EMAIL PROTECTED] If simplifying your config like this doesn't help, look
through the xorg log files (usually /var/log/Xorg.0.log)for lines that
start with (EE) and see if that will tell you specifically why it is
failing. That will give you better direction towards a solution.
I also just noticed your comment about those refresh rates working
elsewhere in another message. It's entirely likely that there are
other options being applied in the xorg.conf files that are overriding
those settings with automatic one, or there are options turned on in
this one that are making those settings unusable. For instance, all of
the options you have specified for fglrx driver may be interfering.
All in all, that is a fairly complex xorg.conf you have there, I'd
strongly suggest paring it down until you have a working config and
then adding all those options back. It's been my experience that
having a "tweaked" xorg.conf increases the likelihood of problems
greatly, and in most cases buys little in terms of performance and
functionality. This is especially true of configs that are
automagically generated by third party tools, which the one you posted
seems to be given the references to XFDrake.
