"Sync. out of range" solution for DP17MO monitor and ATI Rage XL
Just in case someone else gets in the same trouble...
Recently I tried to install Debian sarge (testing) and I found out there
is a trouble with getting XFree86 4.3.0 to work on Sun Blade 150.
This box has Sun DP17MO monitor and on-board ATI Rage XL video card
with 8MB RAM. This combination refused to work nicely in XFree86 4.3.0,
instead the monitor was still displaying a floating "Sync. out of range"
message.
In Debian woody there was working XFree86 4.1.0 so I was desperate to
get working XFree86 4.3.0 in Debian sarge on the same hardware.
And this is what I did:
- checked carefuly /var/log/XFree86.0.log on woody
- found a line:
(--) ATI(0): Reference clock 315/11 (28.636) MHz.
- checked /var/log/XFree86.0.log on sarge
- found a line:
(--) ATI(0): Reference clock 157.5/11 (14.318) MHz.
- found a page:
http://www.xfree86.org/current/ati5.html
- and finally I put in the /etc/X11/XF86Config-4 file
an extra line in "Device" section:
=============================================================
Section "Device"
Identifier "Generic Video Card"
Driver "ati"
Option "ReferenceClock" "28.636 MHz"
EndSection
=============================================================
^^ the line: ^^
Option "ReferenceClock" "28.636 MHz"
^^ was needed ^^
Now I have fully functioning XFree86 4.3.0 in Debian sarge.
Oh, joy :-)
I hope this may help someone out there...
Bye,
