From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0 Description of problem: xv does not show properly stuff (eg. mplayer). A vertical slice of the screen is translated to the right. I have a Trident CyberBlade a1i onboard my Acer 351TEV. It didnt happen with RedHat 7.3. Workaround: I have successfully solved the problem downgrading from XFree86-4.2.0-72 to XFree86-4.2.0-8. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. open a divx with mplayer using the xv video output Actual Results: The video shows corrupted. (It didnt happen with RedHat 7.3) Expected Results: The video should have shown nicely. Additional info: The problem has been introduced with the new rpm XFree86-4.2.0-72 shipped with RedHat 8. Other RedHat version were not affected.
Unfortunately, there is nothing that I can do to debug this problem, as I do not have any Trident video hardware, nor documentation. All I can do is leave this bug report open, and get you to try new versions of the driver that become available from the upstream driver maintainer whom I have CC'd. If you would like to test the latest version, I have XFree86 CVS RPM packages available on ftp://people.redhat.com/mharris/testing/live-grenades however they are not production ready, but rather an experimental developmental work in progress. You can also try the "vesa" driver. Note, you didn't need to downgrade. You could have just took the single trident_drv.o file from RHL 7.3 and used it with the supplied X server in 8.0. In any case, please attach your XF86Config and X server log file from the problematic 8.0 X server (not the 7.3 one you've downgraded to.

I did some more tests: - package 72 with old trident_drv.o from package 8 works FINE. No more bug. - package 72 with new trident_drv.o from package 20021018 do not load at all - vesa video output could not be tested on my machine - x11 video output is always FINE I have just posted my config and log files as requested.
It is not clear what you are saying above. Please be much much more detailed in the information you are providing. >- package 72 with old trident_drv.o from package 8 works FINE. No more bug. I presume from "package 72" that you mean XFree86 4.2.0-72. Please state things like this clearly and explicitly so there is no room for confusion. If you're using the package from RHL 8, with the driver from RHL 8, and not having a problem, then this isn't a bug. If I'm misinterpreting what you're saying however, please elaborate. >- package 72 with new trident_drv.o from package 20021018 do not load at all If you're refering to using XFree86 4.2.0-72 from RHL 8.0 with the trident_drv.o from my XFree86 CVS RPM packages from 20021018, there is no way that that is even remotely supposed to work. Again, you're being totally vague so I can only make random guesses. Please explicitly spell out packages in the form <name>-<version>-<release> to avoid confusion. Do not mix CVS code with older releases. If you are using anything from CVS, make sure you're using EVERYTHING from CVS. Awaiting clarification and greater details.
Hello. Sorry for the inconvenience. I will try to be more clear. If I simply install RedHat 8 on my machine then xv DO NOT WORK properly. If I install RedHat 7.3 instead xv works perfectly. I guess there is a bug introduced by RedHat 8. Thanks to your help I noticed that the problem is carried in by the file /usr/X11R6/lib/modules/drivers/trident_drv.o of rpm package XFree86 4.2.0-72. The best workaround I have found is changing that file with the one from rpm package XFree86 4.2.0-8 (the rpm provided by RedHat 7.3). I am sorry but would like to avoid upgrading my system to a unstable XFree distribution. I have just tried out CVS trident_drv.o unsuccessfully so I came back to XFree86 4.2.0-8 trident_drv.o. There must be a difference between trident_drv.o of package XFree86 4.2.0-8 and trident_drv.o of package XFree86 4.2.0-72. That difference is the problem itself.
Sorry you're having trouble. There's nothing I can do about it really other than relay your problem report to the Trident driver maintainer, whom is carbon copied on this bug report. The Trident driver included in XFree86 4.2.0 in Red Hat Linux 7.3 is the one that is stock. The one included in Red Hat Linux 8.0 is one which includes many bugfixes that Alan did and has solved many users problems. It seems it has created a problem for you and that is unfortunate. Overall the new driver is far superior for more users however, and that is why it is present. You also have the option of trying the latest XFree86 CVS snapshot release available from ftp://people.redhat.com/mharris/testing/live-grenades/ which has Alan's latest Trident driver. While running Red Hat Linux 8.0, and testing the latest XFree86 CVS snapshot available from the above FTP directory, does this problem go away?
I can confirm that I had exactly the same problem with my Trident Cyber 9525/DVD LCD monitor on a Fujitsu Lifebook S-4542, and this is due to the non-stock Trident driver that ships with Red Hat 8.0. XFree86-4.2.0-72 in Psyche/Red Hat 8.0 displayed the identical problem as described by the report with the vertical split screen. The workaround that Mike Harris suggested solved the problem. I grabbed the XFree86-4.2.0-8 RPM that ships with Valhalla/Red Hat 7.3, then used the following to extract the Trident driver file /usr/X11R6/lib/modules/drivers/trident_drv.o: $ rpm2cpio XFree86-4.2.0-8.i386.rpm > XFree86.cpio $ cpio -ivd < XFree86.cpio I moved the old RPM version aside, and copied the trident_drv.o file into place. This restored the DVD screen playback to it's former (correct, no screen splitting) state which it had as of Red Hat 7.3. I am not on broadband connection so I have not had a chance to test Mike Harris' pretest XFree86 RPMs for XFree86 4.2.1 (CVS snapshot version). As soon as I get access to a fast connection I will try the pretest RPMs to see if the problem remains in the Trident driver that ships with that version. Alex
Problem has been reported upstream, so I am closing this now as WONTFIX as I have neither the hardware, nor the documentation to investigate this. It will either be fixed in XFree86 4.3.0 when released, or some future release perhaps. Please follow up bug reports directly to XFree86.org for this hardware by sending email to xfree86@xfree86.org
I also had the same problem (and wasted much time trying to fix my /etc/X11/XF86Config file). A good workaround to this problem is to get a new driver published by the maintainer. You can find it at http://www.xfree86.org/~alanh.
The trident_drv.o actually proposed bu the mantainer does not fix the problem for me. I still use the one which came with Red Hat 7.3 (build#8).
Problem have been solved on RH9.
Cool, thanks. Closing bug as resolved in CURRENTRELEASE of Red Hat Linux 9. (XFree86 4.3.0-2)
