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, Wiktor Wandachowicz
