  • ati-drivers-8.27.10-r1 - possible scan rate control problem?

    Hi,
    New forum member here. Thanks in advance for putting this forum together. It looks like it can be quite helpful.

    QUESTION: How do I set the monitor scan rates in xorg.conf for 8.27.0?

    I'll keep it moderately breif. I'm a Gentoo user with a MythTV network that's been up for about 16 months. I run a 2-tuner server, 3 Linux desktop machines that run mythfrontend, and two dedicated Pundit-R machines attached to TV. The network was in need of updating so all the machines got new kernels which necessitated new ati-drivers where appropriate. I have Myth running correctly and displaying to most machines but I have one Pundit-R machine that's having some problems. I suspect it's a scan rate issue, or would at least like to eliminate that as a problem.

    1) I have two Pundit-R machines. Here is how lspci shows the VGA:

    myth14 ~ # lspci
    <SNIP>
    01:05.0 VGA compatible controller: ATI Technologies Inc Radeon 9100 IGP
    <SNIP>
    myth14 ~ #

    2) Both of these machine have been updated and are running as much as possible exactly the same software. (Myth, ati-drivers, Gentoo stuff, fluxbox)

    3) Both machines use the S-Video output to drive TVs. The one that fails also uses the conposit video output.

    4) One machine works completely correctly driving the Sony in the bedroom.

    5) One machine fails with a blue screen on the Mitsubishi in the living room.

    6) The failing machine has mythfrontend and fluxbox running when I ssh into it. If I kill them I see the screen on the Mitsubishi come back to the console and the myth and fluxbox restart automatically by design. The TV then goes blue screen again like it's getting no signal, or a signal with the wrong scan rate or no signal output.

    7) Even though I used the aticonfig program to update the xorg.conf file it seems that there are still things that aren't correct:

    myth12 ~ # cat /var/log/Xorg.0.log | grep EE
    Current Operating System: Linux myth12 2.6.16-gentoo-r13 #1 PREEMPT Thu Jul 20 18:57:49 PDT 2006 i686
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
    (II) Loading extension MIT-SCREEN-SAVER
    myth12 ~ # cat /var/log/Xorg.0.log | grep WW
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
    (WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/local/".
    (WW) fglrx(0): board is an unknown third party board, chipset is supported
    (WW) fglrx(0): MonitorLayout is no longer supported.
    (WW) fglrx(0): The hex number setting for DesktopSetup is deprecated,
    (WW) fglrx(0): Specified desktop setup not supported: 8
    (WW) fglrx(0): DRI is not supported on Radeon 9000/9100 IGP (RS300/RS350) hardware.
    (WW) fglrx(0): Option "IgnoreEDID" is not used
    (WW) fglrx(0): Option "NoTV" is not used
    (WW) fglrx(0): Option "VendorName" is not used
    (WW) fglrx(0): Option "ModelName" is not used
    myth12 ~ #

    If I can fix that stuff along the way that would be great also.

    7) In my /etc/X11/xorg.conf file I no longer see a command for setting the scan rate of the monitor. I have a vague recollection of having this problem using the driver 16 months ago and having to set the scan rate down to something low.

    I can post lots of other info here if needed. I'll stop for now and hope for some conversation on the problems.

    Thanks in advance,
    Mark

    Hi after a bit of an absense,
    I tried out the newest ati-drivers package today - 8.29.6 - and notice a marked improvement in all areas. It's not nearly as good as the much older pathced 8.14 driver I was able to use with the older kernels but it is FAR, FAR better than the versions I was running as recently as a few weeks ago.

    The problems with what appeared to be missing frames is pretty much gone. there is, however, still considerable tearing of background images as a scenes is panning. I note also that CPU usage seems to be better with this new driver. With 8.28.8 my Pundit-R CPU fans would start spinning up to presumably cool the CPU. With the new 8.29.6 driver this does not, so far, appear to be the case.

    If anyone is having problems at all like where discussing earlier in this thread they might well find things better after loading this newer version.

    Cheers,
    Mark

    I did try disconnecting the S-Video out. It didn't change anything. I don't have an S-Video to composite adapter. Maybe Radio Shack or Fry's carries something like that. Don't know.

    I would be in better shape also if I could find a Cable TV set top box that had S-Video output. Basically I just need both devices (MythTV and set top box) to use the same technology so that I don't have to change inputs.

    In the meantime at least it's working, tearing and jerky video as it is. It's watchable, but just barely.

    Maybe there is something new in the way you have to configure a 2.6.17 kernel to get good video? I don't know. I jsut used my 2.6.16 .config file and did make oldconfig.

    Thanks,
    Mark

    I Was just reading the Gatos pages. It appears the 9100IGP is really R300 and apparently TV out is not working well on that series for them. I don't think I'm brave enough to go that direction right now.

    Have you tried using TexturedVideo for improved video playback? More @ http://www.phoronix.net/forums/forumdisplay.php?f=19
    I didn't know about it. Let me go read a bit on that. I'll likely try some thigns out tomorrow sometime.

    Thanks for all your help,
    Mark

    I guess there is also the Gatos drivers but I don't know a thing about them. They are listed as 'testing' in portage so it's no big deal to build them. I'm more concerned about how to build a proper xorg.config file if I was to go that way.

    I'm certainly interested in what folks think the options are, but I'm also sort of shocked at how much worse the mpeg performance is on this new ati-driver compared to the one I used a year ago. Bummer...

    Thanks!

    You will be best off using the open-source drivers for the R200 generation components.

    Not much to say here. It just listed 'tv' as the only thing it saw. No clues I can gather about how to get proper X11 video/graphics on the composite video output so far.

    Hi again,
    After viewing the quality of the video output I'm seeing a LOT of video 'tearing' as a scene changes quickly. It's like the mpeg stuff was only doing part of the frames or something.

    This is MUCH worse than the older driver, at least with the setting sI have right now.

    QUESTION: What stuff should I be checking on a 9100 IGP to ensure the best performance I can get?

    I understand that this chipset doesn't do 3D acceleration. glxgears is giving me only about 100FPS. Everything seems very slow and the video is NOT smooth like the older driver.

    Should I be able to do DRI stuff with this device? I'm not clear. I tried to reconfigure the driver and kernel but couldn't find any settings that allowed me to see DRI/DRM enabled.

    Thanks again!
