Re: TV Card + X11 = problem!?

Personally I've experienced this problem with Linux Ubuntu Desktop, Linux Ubuntu Server, Arch Linux, with different keyboards but only in X11 environment (not in any console). The Xorg log file doesn't contain any errors, neither the kernel ring buffer (dmesg). Does any one know anything about this problem? That is weird. I had this problem for a while, and I also have a TV card (analog). It never occurred to me that it might have something to do with the card. My TV card uses an SAA7130 chip.

Doesn't make much sense, yesno? :-)
Now that I read it again, it was a bit confusing. I was thinking that
the way the compositor unredirects fullscreen apps has a bug. However,
I completely disabled compositing and restarted and the bug was there,
so I guess it's not the compositor's fault.
(It's rather likely that the indirect rendering works and the bug occurs on
direct fb access through xv - tried other -vo sinks, eg. gl or x11?)
Gl and x11 output work correctly. It's only Xv + direct rendering that
triggers it.
You could try by shutting down kwin ("kquitapp kwin") and launching s (or
rather maybe just) mplayer - then "mplayer -fs some_movie.avi"
To restart kwin call "kwin&"
NOTICE: since w/o a WM you won't be able to pass the focus around, you might
want to call all cmds in a row
"kquitapp kwin; mplayer - then "mplayer -fs some_movie.avi; kwin&"
do not attempt to fork mplayer to bg (won't show up then)
If this (unexpectedly) works fine, you can try to suspend compositing
(SHIFT+Alt+F12) before playing
In both cases the bug shows. Really the only case where it doesn't is
with compositing active (which means KWin must be running and desktop
effects must be enabled.)

This seemed to be the result of using a KDE 4.3 built against Qt 4.6 (this is not officially supported by KDE). I've since downgraded to Qt 4.5 and rebuilt KDE. This seems to have fixed the issue (mostly). X still uses more and more memory as uptime goes up, but not as dramatic as reaching 800MB after 5 hours. At boot-up, X starts with about 60MB of memory usage. Right now, after about 3 hours, it's at 170MB and slightly increasing with time. xrestop doesn't show anything interesting: adding up all the "Total" values reported only amounts to about 20MB or memory. Where the missing 90MB are spent, I've no idea. But in any case, we're now talking about 90MB unaccounted for instead of 700MB previously. ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

Most of the internet is extreme lowfi designed for 1024x768 or > below. It's only visible to me in "extreme" cases, like a red box on white background; there's a bit of red "running in" the black (I think that's called ghosting) or the default X background (this one always made my eyes cry with my old CRT). Nothing serious though. But since my monitor *is* digital (TFT) and my graphics card is also digital, it makes more sense to use DVI-D. With VGA, the graphics card converts its digital signal to an analog VGA signal and sends it over the cable. The monitor picks it up, and since it's a TFT monitor (they need a digital signal to display) it converts the analog signal back to a digital one. With DVI-D, the signal is just sent though the cable with no conversions and cable quality doesn't matter the least since it's digital. It makes more sense to me to use it that way rather than doing a totally useless and unneeded conversion from digital to analog and then back again. If you don't have a TFT monitor but a CRT instead, then this in not an issue at all. CRTs are analog (there's a few modern digital CRTs too, but you would know if you had one).

Well, it's certainly possible that the driver became that much slower. But doing the benchmark right would be so easy, yet Phoronix didn't do it. All I need to do here, is simply remove the old driver and install the new one and re-run the benchmark. Everything else stays the same. Dead easy. Yet Phoronix didn't do it.

That would be just a temporary solution with too many problems (since I assume a real solution will be in DRI2?) The OpenGL method with VSync works quite well. ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

You'll have to use a media player that can render in OpenGL and enable VSync. At least, that's how I was able to get acceptable video without tearing. ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
