Help, all X users,
For the last two weeks, I've been trying to get
XFree86 4.1.0 to work properly with hardware I
have that worked properly with XFree86 3.3.6.
Here is the list of hardware*:
Flamingo PCI SVGA graphics card based on the
Cirrus Logic CL 5434-8 chipset.
Compaq 471 SVGA monitor
HorizSync 31.5-38
VertRefresh 50(?)-90 (question mark added)
NEC Multisync 3V monitor
HorizSync 31.0-50.0
VertRefresh 55-90
Both monitors worked properly when I used XFree86
3.3.6 on Slackware 7.1 using the XF86Config file
that I've [NOT] attached. The modeline that worked
with _both_ monitors is listed below:
# 1024x768 @ 87 Hz interlaced, 35.5 kHz hsync
Modeline "1024x768" 44.9 1024 1048 1208 1264 768 776 784 817
Interlace
I recently upgraded to Slackware 8.0, which uses
XFree86 4.1.0. The modeline shown above was
inserted in to the XF86Config-4 line as shown
in the file I've [NOT] attached. Rather than working,
the following message is generated in XFree86.0.log
file (also [NOT] attached):
(II) CIRRUS(0): Not using mode "1024x768" (bad mode
clock/interlace/doublescan)
I've tried other modelines for 1024x768 as shown
in the XF86Config-4 file. Either they don't work
with either monitor or eventually cause the
NEC Multisync monitor to shut off (this might be
a problem with the monitor, TBD).
I've read the XF86Config and Timing HOWTOs and I've
used some of the modeline generation tools available
on the Internet. Notably, none of them help in
generating a modeline with the "interlace" flag.
Whenever I've set up a 1024x768 modeline without
interlacing, it won't sync with the Compaq monitor.
The modeline also causes the NEC monitor to eventually
shut itself off. If I set up a 1024x768 modeline
(or any other) with the "interlace" flag included,
a "bad mode clock/interlace/doublescan" error message
is generated for that modeline and it is ignored.
I've run out of ideas on how to solve this problem;
short of uninstalling 4.1.0 and reinstalling 3.3.6
That is something I really don't what other than as
a last resort. Any help would be greatly
appreciated, especially in understanding how to
properly generate modelines which call for interlace.
Mac
* I've also been working with a TV57 PCI board,
based on the Trident TGUI 9680, which also works
with XFree 3.3.6, but utterly fails with 4.1.0.
Briefly, every 8 horizontal pixels are repeated
twice on a line. That is another story, though.
