Description Paul Gear 2002-05-19 06:34:45 UTC

Description of Problem:
X display has incorrect colours (black shows up as white) unless ShadowFB option
is turned on, LCD screen flickers constantly, especially on grays.

Version-Release number of selected component (if applicable):
	XFree86-4.2.0-8
	XFree86-SVGA-3.3.6-44
   previous revisions on RH 7.2:
	XFree86-4.1.0-15
	XFree86-SVGA-3.3.6-42

How Reproducible:
Every time

Steps to Reproduce:
1. Upgrade from RH 7.2 to 7.3
2. Marvel at how smooth it was compared to previous upgrades and how few config
files were mangled.  :-)
3. Start X.
4. Tear hair out for 4 hrs trying to find the right option on the Trident driver
that will actually display black correctly (ShadowFB - was not needed under
previous version).  ;-(
5. Go cross-eyed looking at the flickering LCD.

Actual Results:
	I don't know if the video modes selected are wrong under the new version, but
the screen image is not nearly as stable as under RH 7.2.

Expected Results:
	Screen looks as good as under RH 7.2, or even better, as good as Windows 98. 
;-)

Additional Information:
	The Windows 98 driver has always worked perfectly, providing 32-bit colour. 
The previous XFree driver would only do 16-bit, but it was very stable and easy
on the eyes.  I've searched for info on the changes to the Trident driver at
XFree86.org, and i can't find anything significant to my problem.

Comment 1 Mike A. Harris 2002-05-20 23:23:40 UTC

I've Cc'd the Trident driver maintainer for comment.  Please attach your
X config file and log file in the mean time.

Comment 2 Alan Hourihane 2002-05-21 07:54:47 UTC

Can you pick up a new driver from http://www.xfree86.org/~alanh
and copy it to /usr/X11R6/lib/modules/drivers. Make sure you
backup the old one.

And try that.

Let us know.

Comment 5 Paul Gear 2002-05-21 08:55:54 UTC

The XFree86.0.log is actually 43650 lines long.  All of the lines after those
supplied in the attachment are like the last line.  There are only 370 unique
lines.

Comment 6 Alan Hourihane 2002-05-21 09:19:34 UTC

Did you try the new driver ??

Comment 7 Paul Gear 2002-05-21 10:02:33 UTC

Yes.  I can't see any discernable difference.  How can i confirm that i am
actually using the new driver?  Do you want to see the log under the new driver?

I did some investigation on XFree86.org after i logged this bug, and i found
several hits where people reported that their Trident cards had varying problems
after upgrading to 4.2.0.  None of them seemed to have any resolutions posted.

Comment 8 Alan Hourihane 2002-05-21 10:24:24 UTC

Make sure you power down before trying again.

And yes - please send a log with the new driver.

Comment 9 Paul Gear 2002-05-21 10:33:59 UTC

Powered down and tried again - definitely no better.  Log follows.

Comment 11 Alan Hourihane 2002-05-21 10:53:52 UTC

Your not running the new driver as it should come up with a different version
number.

Can you make sure it's installed in /usr/X11R6/lib/modules/drivers

Comment 12 Paul Gear 2002-05-21 11:03:49 UTC

Here is a listing from my drivers directory:

-rwxr-xr-x    1 root     root       123754 May 21 19:55
/usr/X11R6/lib/modules/drivers/trident_drv.o*

/usr/X11R6/lib/modules/drivers/trident_drv.o.old*

md5sums:

e5216fa31f3515e2cd6ccf2139279cab  /usr/X11R6/lib/modules/drivers/trident_drv.o
896087845ceba148694a850bfc6de6ac 
/usr/X11R6/lib/modules/drivers/trident_drv.o.old

Have i got the right file from your web page?  I can only see one
trident_drv.o.  The web server says this:

> HEAD /~alanh/trident_drv.o HTTP/1.0

Looks OK...

Comment 13 Alan Hourihane 2002-05-21 11:21:41 UTC

Mmm,

I've just uploaded my latest. Try again now.

Comment 14 Paul Gear 2002-05-25 06:52:02 UTC

Tried the latest driver - still flickers badly, especially with grey colours.

Comment 28 Mike A. Harris 2002-08-08 10:31:17 UTC

Does this problem still occur in rawhide XFree86 with the Limbo beta?

Comment 29 Paul Gear 2002-08-09 09:28:29 UTC

I have not used the latest beta, nor am in a position to do so now.  Alan has
provided me with an updated Trident driver (1.0.15).  If the beta contains this
version or later, i'm sure it will be fine.  Alan is actually still waiting on
me to try some different combinations of options in the XF86Config.

Comment 30 Mike A. Harris 2002-08-09 13:39:11 UTC

Ok cool.  Thanks.
