Bad artifcats on TightVNC

heya,

I have a box with Arch Linux 64 and TightVNC 1.3.10 installed.

Graphics card is a Nvidia Quadro NVS 290:

01:00.0 VGA compatible controller: nVidia Corporation G86 [Quadro NVS 290] (rev a1)

with the Noveau drivers:

extra/xf86-video-nouveau 0.0.16_git20110726-1 [installed]
    Open Source 3D acceleration driver for nVidia cards (experimental)

I've set the TightVNC viewer connection profile to "high-bandwidth", and disabled JPEG compression, and the image quality is appalling bad. I've also tried changing encoding in the viewer from Hextile to RAW, still the same result.

I've uploaded my TightVNC logfile to here http://paste.pocoo.org/show/460633/

Any suggestions on what's going on, or how to improve this?

Thanks,
Victor

victorhooi,
Hi.  I redacted the large image in your post and changed it to a link.  If you would like, feel free to edit it and include a link to a thumbnail like this:

[url=http:/pathToBigPicture][img]http:/pathToTheTumbnail[/img][/url] 

  That way, members can see the thumbnail and, if they wish, can click through it to the big image. 

Thanks

I assume you are using compositing in KDE?  If  so, have you tried turning it off?

Re: Bad artifcats on TightVNC

heya,

@ewaller: Lol, funny you should ask - it actually isn't on.

I just checked in KDE, and under Desktop Effects for compositing it says:

Required X extension (XComposite and XDamage) are not available

Not quite sure how to fix that, or whether it's related to these TightVNC issues. If I start up a normal root X session on the box the quality is fine, obviously.

I've also got the TightVNC logfile in the first post, in case that helps shed any light.

Cheers,
Victor

TightVNC is oooooooold. Try TigerVNC, it's in AUR.
