Description Telsa Gwynne 1999-12-03 16:24:36 UTC
Running 6.1 on a machine with a Cyrix MediaGX chip and 64megs RAM.
Had an old monitor that X worked with. Got a new one:a Sony CPD-110EST.

Ran Xconfigurator and it told me it had found settings for it, but the
ones it suggested were 1280x1024x8bit. Although the monitor might cope,
I'm told the MediaGX has a limit of 1024x768.

Called in friendly neighbourhood hacker (every home should have one) to
sort it out. I'm now using an XF86Config with
this in it:

# 1024x768 @ 76 Hz, 62.5 kHz hsync
# Modeline "1024x768"    85    1024 1032 1152 1360   768  784  787  823
Modeline "1024x768"    85    1024 1040 1152 1360   768  784  787  823

This is working fine.

So far :)

Does this work in Red Hat Linux 6.2?

Comment 2 Trond Eivind Glomsrxd 2000-07-26 14:20:15 UTC
Xconfigurator doesn't have a way to specify minimum/maximum resolution (also a
problem with LCD displays) - intend to fix this with a planned rewrite.

Comment 3 Trond Eivind Glomsrxd 2000-07-26 14:20:43 UTC
Oh - and of course, the workaround is to select the resoultion you know your
computer can handle.

Comment 4 Telsa Gwynne 2000-08-02 12:21:54 UTC
It does not work any better in 6.2.

The workaround only works if you are prepared to edit the
XF86Config file by hand. If I select combinations of resolutions
and depths in Xconfigurator, it claims to accept them and then
writes a non-working XF86Config.

Subject: Cyrix MediaGX text-mode upgrade: step right

It's not all doom and gloom: Xconfigurator --preferxf3 gets
Cyrix right. Woo-hoo! Thank you! (Please someone with privs,
#7551 so that everyone knows this is now working: unless you
see the other beta-team-only bug, you don't know that
was fixed for 7.0, and I keep meeting people with Cyrixes and
working X because they don't know there's a new
