Slackware 10.1 (Full Install):

KDM: when using kdm and i try to exit one WM it hangs on black console. Nothing responds.. reset the only way. Y?

GDM: when using GDM i can't export/accept DISPLAY. i.e:
(user):$ xhost +
(user):$ su
<password>
(root):$ export DISPLAY=localhost:0
(root):$ nedit

Can't open DISPLAY :0.0. Something like that... Y?

X start/end takes a while...not fast enough! ?

When running and X app and moving its window ( specially with tv apps )... it sticks on screen. i.e with tv app.. frames of it stick all over the screen when moving the window of toggling Fullscreen on/off and the only way to clear the screen is restart the WM/X . xorg issues maybe? Any1 knows what causes this problem?

I had no problems of this kind (X related) with slackware 9.1 and xfree on the same system.

Have you configured xorg? If not run xorgconfig

Off course! Everything is well configured. 3d is also enabled correctly. I have even enabled xvideo extention + DGA support for tv.

Well you could use sux if you want to open X objects as root

Use your IP and not localhost. Does it work? sux is probably the best way though.

Booting in init3 solves the problem of running X apps as root. I'm just looking for a solution to the last problem. But recently another problem appeared... i get segmentaion fault often lately when trying to run any command , even xterm, even reboot. The last one is definetely a slackware problem rather than X one.

Sounds like you're possibly having data corruption. How old/new is your HD? I can remember I had that same problem where every command caused a seg fault. Like simple stuff like 'ls' and 'cd'. Turned out the partition was corrupt. If you have like slax or some bootable cd distro use some hd utilities and see if they can find anything wrong. fdisk can sometimes tell if a partition is corrupt.

Yes, my HW is old.. (celeron 466) and the hdd is also 4-5 years old. And i had not formatted it for a couple of years... and i just installed slack10.1 without recreating partitions, just quick formatting the existing ones.

Well I would say it is very likely to be a HD issue then. Or possibly just a partition issue. Might be bad sectors. You can get like the max blast or whatnot and use that to scan your HD and it should also mark any sectors as bad so that they won't be used and gradually corrupt everything.

I booted knoppix and rebuilt the slackware root partition tree.. and seems to be more stable now. But the X problems still remain unsolved. But the most irritating prob is that when trying to play a movie with mplayer and xv video out the colours are corrupted... It's not watchable. I tried different vo drivers (x11,sdl,gl2...) but i can't get nice colours,fast motion and full screen at the same time. Anyway to fix this?

What are your video card specs ?

I had problems with the picture not moving correctly when scrolling but it pretty much cleared up when I set the video card memory to the right value in my xorg.conf

My video card is i810 onboard. Yes it's true.. i have same problems too, when scrolling. I can't set the memory value beacause this card allocates dynamically memory from RAM and it's sytem and OS depended. Now i'm in front of a bug and i can't find out what is going on....:

I uncomment the omit-dga option in xorg.conf so that it won't load that extension module. I uninstall mplayer. Restart X. Configure,compile and reinstall mplayer. play a video with mplayer but the picture is awful (problems remains). I restart once again X without changing anything. I play again a video with mplayer. Now the colour is correct (strange). I close it and open xdtv(tv app like xawtv). Now the clour is f*cked there and can't watch tv (same colour as it was with mplayer before -- too transparent, overlay is not supported anymore). I close xdtv and try again to play a video with mplayer. {Surprise!) Colour is once again f*cked. I restart again X without changing anything at all. The 1st thing to do when the WM loads is play a video with mplayer. Colour is correct once again. I close it and open xdtv. Colour is bad.I close it and play again video with mplayer. Colour f*cked again. Restart X. Now the 1st time to do is open xdtv. Colour bad again, and so mplayer.

Conclusion: Mplayer works fine without DGA support, unless i open xdtv. Then it doesn't work correctly.It doesn't work either way with DGA support though. Xdtv can't show nice picture without DGA support, but it works fine with DGA. WTF? (what the f*)

Any1 has any clue what might b wrong? I'm pretty desperate with this situation

HW:
video card: i810.
tv card: philips flytv (saa7130/34)

Conf:
3d Enabled
Working Resolution 1024x768
kernel: 2.6.11.2 (2.4 doesn't support saa7130/34)
xorg ( slack 10.1 dflt version).

I can give any other info if any1 is interested. THNX!

If the video card memory is OS dependent maybe you should try setting a few meg in xorg.conf and see what happens. It might at least stop the scrolling crap.

I made one change now (i didn't think it would matter)

in section screen, in every display subsection i removed the virtual option and reenabled dga. Now both tv and mplayer work fine BUT, once i run xdtv... then i can't get mplayer to work correctly. It works fine unless i open tv. TV works fine in any order. I may be close enough to the solution. Any suggestions?

(I think there must be something with the order that xvinfo detects adaptors. Once the adaptor is used for tv occupies the xvideo port it never lets it even when i close tv, or something like that, dunno... too complicated for me)


Oh.. and one more problem... when watching tv.. sometimes (randomly) system hangs.. No keyboard,no mouse, nothing.. but tv keeps working (?)
