Screen corruption with fglrx X driver

I have a rather interesting problem. I have been trying to get MythTV up
and running on my HTPC box. I have a Radeon HD 2600 Pro graphics card
which is connected to my TV via a DVI->HDMI adapter, and the display
runs full-screen at 1920x1080. I was initially trying to get MythTV to
work using the radeonhd graphics driver, however hardware acceleration
is not yet supported for this driver so watching live TV is essentially
impossible because all the rendering must be done by the CPU, so I gave
up on that idea.

Plan B was to use ATI's proprietary fglrx driver, which I managed to
install and get to work, complete with which means that 2D and 3D
hardware acceleration, so I was hoping that it would be straightforward
to get MythTV working. However, I found when I ran mythtv-setup, and
also later when I ran mythfrontend, that the display output gets
corrupted, as can be seen at
http://www.allpowerfuldave.com/mythtv_corruption.jpg. It's clear to see
that this is trying to be MythTV, there's just something not quite
right. If you take a screenshot, the screenshot is fine so MythTV is
drawing all the components correctly, so I surmise that there's
something going wrong between MythTV and fglrx, because the MythTV menus
displayed correctly when I went back to using the radeonhd driver.

Can anyone shed any light on what the problem might be?

Thanks in advance,
David

Re: Screen corruption with fglrx X driver [In reply to]

Thanks for the suggestion Lauri, unfortunately it didn't fix the problem. I
also discovered an interesting new twist to this problem today: in the
Fedora 8 installation on the same box (I was running Fedora 9 when I ran
into this problem), with exactly the same version of mythtv and Xorg, also
running the fglrx driver, the display output is perfect and TV playback is
flawless. The only difference I can think of that would account for this is
the difference in the version of the Kernel, although it's only a minor
point difference - both are 2.6.25 stock Fedora kernels, and the F9 kernel
is more recent than the F8 kernel.

Just to clarify, this screen corruption occurs in the MythTV menus as well
as during TV/video playback.

Regards
David

David:

I had this same problem with my HD 3200, when attempting to use the
fglrx ATi proprietary driver. I cant recall exactly what fixed it, but
I know I was able to. I have since gone back to my older Nvidia-based
machine, as I was having tearing issues with the fglrx driver.

Whats interesting is, if you tell Myth to run in a window, or at any
resolution smaller than your full screen resolution, the issues doesnt
show up. At least, not on my system -- and I read others experiencing
the exact same thing. Very odd. For example if my screen resolution
was 1360x768 and I set Myth to run windowed at 1280x720... no screen
corruption! Very very peculiar.

These are a few settings from the last version of my xorg.conf (from the
DEVICE section) that I know I was playing with during that time, so
perhaps one of these will do it:

Option "VideoOverlay" "off"
Option "OpenGLOverlay" "on"
Option "TexturedVideo" "on"

Once you get it working, I'd be interested to hear if you see any of the
video tearing issues or not. I've read reports of others seeing it with
the fglrx driver, as well, with the HD 3200 chipset. Doesnt matter if
I'm playing back SD or HD material, I was seeing it. It wasnt terrible,
by any means, but it was enough to annoy me... hence why I swapped my
desktop and myth hardware to give myth the nvidia stuff, until the
drivers get sorted out.

I knew I was taking a gamble with the AMD 780G chipset and the ATi HD
3200 graphics, so I'm not upset it isnt working perfectly yet (for me)
-- but I feel confident that it will eventually work.

Hope that helps.....
--Eric

I am having the same problems as described above. I am using a
GIGABYTE GA-MA78GPM-DS2H motherboard which has an onboard ATI HD3200.

I have seen other posts that indicate VideoOverlay should be on and
OpenGLOverlay should be off. Regardless, neither combination works
for my frontend.

However, I can get passed the garbled picture David posted above by
doing what Eric suggested... setting the geometry for mythfrontend at
the command line, eg:

mythfrontend --geometry 800x600

Unfortunately, when I try to watch a recording this way, I get two
duplicate videos... one right on top of the other. Very strange....

I am running it on a CentOS 64-bit system with everything up to date...

Jason:

I also had the issue with the duplicate videos. The duplicate videos
one ontop of the other is an issue with the deinterlacer I was using at
the time. Are you using Bob(2x)? I got the same picture issue as you
described, two copies of the video, with Bob. When I changed to a
different deinterlacer, it went away. Play with your deinterlacers and
you should be able to get that issue to go away, at least. I think I
ended up using Kernel, perhaps? I cant remember... but I was able to
fix that issue, for sure.

Heres something else to try, for the screen garble running in full
screen mode. I think it had something to do with when mythfrontend was
trying to use DRI. Try turning DRI off in the xorg.conf file (not sure
the command, sorry, I just removed permissions to /dev/dri/video0 so
that mythfrontend couldnt access it), and the screen garble seemed to go
away. I'm afraid not using DRI is why I was having screen tearing
issues -- not positive of that however -- but at least not using it
didnt garble the screen.

I'm pretty sure thats how I fixed it on my system, had to look back over
the notes I was taking at the time of all the different things I was
trying. :)

If you get the screen garble to go away, please report if you have any
issues with video tearing, with the HD 3200. I'm curious to hear.

BTW, I have the same motherboard as you. Well, almost. Mines the DS3H.

Good luck...
--Eric

Re: Screen corruption with fglrx X driver [In reply to]

Thanks to all for the various suggestions; using the --geometry argument
fixes the problem with the screen garbling - I'll havea a fiddle with some
of the xorg.conf settings and see if I can fix it for fullscreen too using
the ideas that have been put forward.

When viewing widescreen HD content, I also saw the duplicate videos stacked
on top of each other. How do you change which deinterlacer is being used?

Re: Screen corruption with fglrx X driver [In reply to]

I've done a little more investigating and tried tweaking some settings, and
here are the various problems I've identified; I would appreciate any input
anyone can give me.

1. Mythfrontend menus: if I run mythfrontend using the --geometry parameter,
the menus always display correctly. If I omit the --geometry parameter so
that mythfrontend runs full-screen, then the output on the screen gets
corrupted (although a screenshot shows the menu drawn correctly). I have
found that if I change the paint method from Qt to OpenGL, the actual menus
themselves then display correctly, although the initial loading screen with
the progress bar still appears corrupted.

2. Settings screens: If I have the OpenGL paint method enabled (to fix the
screen corruption as described above), none of the settings screens work -
the screen doesn't change and doesn't respond to key presses, although
pressing Escape enough times usually regains control of the menus. However,
this is only happens in full-screen mode: running mythfrontend with a
--geometry parameter gets around this problem. If I am using the Qt paint
method, this menu works all the time (however it's useless in full-screen
mode because of the aforementioned screen corruption in full-screen mode
without OpenGL).

3. Watching TV: generally works; however, mythfrontend frequently segfaults
while watching TV. Changing channels is also problematic: most of the time,
this causes the TV output for the newly changed channel to be garbled.
However, pressing escape to get back to the main menu and then going back to
watching TV results in that channel being displayed perfectly. See
http://www.allpowerfuldave.com/mythtv1.png,
http://www.allpowerfuldave.com/mythtv2.png and
http://www.allpowerfuldave.com/mythtv3.png for examples of the garbled
output after changing channels. The output appears to differ depending on
whether the broadcast is SD or HD.

Any insight or suggestions would be greatly appreciated.

Re: Screen corruption with fglrx X driver [In reply to]

I ran into a similar problem over the weekend while trying to build a
new frontend/backend system on an Asus Pundit 2, which has a Radeon
X1200 onboard. I'd installed the latest 8.512 RPMs from livna and found
similar corruption in mythtv-setup and mythfrontend. I've just now
removed 8.512 and installed 8.501 - the menus in mythfrontend now look
fine. I'm still getting a doubled image in LiveTV, but the menu issue
has been resolved.

Just wanted to chime in on this very old thread, I'm seeing exactly
the same problems as described above. Anyone know of any solutions
yet? I'm ready to give up and plug in an older GeForce 6600 into the
PCI-E slot.

My setup:

GA-MA78GM-S2H (AMD 780G)
CentOS 5.2
fglrx
Connected via DVI

I'm hoping that eventually a new driver from ATi will be released that
fixes this problem... but for now, I'll switch over to the PCI-E card.

Thanks!

Re: Screen corruption with fglrx X driver [In reply to]

I've had the same problem, today I have updated to catalyst 8.8 and seems to
work fine...
Can you confirm?

Hey,
I have the same motherboard in my frontend but am using Ubuntu 8.04.
Using ATI's 8.7 drivers I have this exact problem, but I didn't have
it using 8-3 or 8-6. I still have curruption on channel changes
between resolutions (SD to HD and back) but escaping back to the menu
and going back to the tv fixes it.
I had tried 8-7 to fix the above issue but rolled back because it
introduced more problems than it fixed for me.
I haven't tried 8-8 yet, hoping though.

cheers,
Owen.

Re: Screen corruption with fglrx X driver [In reply to]

I too have the same issue. I just did a clean install of 8.04 with the
recommended patches. I installed Mythtv before using the ATI drivers and
everything worked well. I downloaded version 8.8 catalyst, did the
--buildandinstallpkg option as per release notes and everything seemed ok
until I ran MYTHTV. When I ran mythtv at default for my display (1440x900) I
got the problem you guys are experiencing (missaligned/pixelated). If I
specify --geometry 1439x899 it works fine inside the GNOME display with top
and bottom menu bars showing...

Yeah, same issue I had using newer drivers. I mistakenly said I was using 8-6.
I'm currently using the 8-3 drivers in the Ubuntu 8.04 repositories:
i xorg-driver-fglrx 1:7.1.0-8-3+2.6.24.13-19.45
^^^
Using this I have the corruption on channel changes between
resolutions (SD-HD and back) but everything else seems to run fine.

cheers,
Owen.

I have been experiencing the same problem for weeks now. Last night I
updated to the latest ATI driver release and still experienced the
tearing. I searched the web and found an environment variable that
"fixes" it:

export LIBGL_ALWAYS_INDIRECT=true

I found the clue here:
http://forums.fedoraforum.org/showthread.php?s=806b7f10b546b6dd0ee48d4780ad0daf&t=127834&page=2&pp=15

I also had the split screen due to interlacing, I will try some
settings tonight to correct that too.

I am very keen to get a proper fix..

Rob Barnes

Re: Screen corruption with fglrx X driver [In reply to]

Well I don't know if this is coincidence, but here's what I figured out.

1. When using 32 bit version of 8.04 with either fglrx or ATI drivers,
got the screen tearing problem no matter what. (Yes, even using latest
catalyst 8.8 drivers).
2. When I switched to 64 bit version of 8.04 (I have a dual core 2.2ghz
laptop with built in HD RADEON 2600) and installed the fglrx drivers from
Ubuntu, followed by Mythtv, everything worked fine. No tearing, no other
weird problems. I even watched 'office-space' fullscreen without incident on
such said laptop.

Could be coincidence or maybe something that is implemented better with the
64 bit fglrx drivers?? I still haven't installed the catalyst 8.8 drivers
but I'm not sure I need to at the moment...

Re: Screen corruption with fglrx X driver [In reply to]

I checked my configuration, and I am using catalyst-8.8 on my 64-bit
install of CentOS 5.2.

I was able to avoid/fix the 'checkboard of death' problem by setting
passing a --geometry flag to mythfrontend as people have suggested in
this thread, setting it one pixel larger than the actual screen
resolution.

However, it looks like I am having vsync problems... I see image
tearing when watching recording. Tried all kinds of combinations to
enable/disable vsync using OpenGL (in the MythTV menus); as well as
fiddling around with the aticonfig/GUI... it didn't seem to work.

For now, I'm switching over to XvMC on my 6600. Hopefully ATi will
resolve these problems in the next release.
