PetoKraus: hello lads
PetoKraus: got a question for you: http://www.irc.gjh.sk/pastebin/696
PetoKraus: using arch linux x86_64
Erektium: what is the question
PetoKraus: well obviously
PetoKraus: PTS doesn't wanna continue
PetoKraus: and gcc is installed. so i don't see why is it bitching.
PetoKraus: also, i thought that PTS is not 32bit dependant...
redeeman: stuff it runs may be 32bit only
redeeman: but pts itself is written in php and thus runs anywhere it does
PetoKraus: redeeman: yes, that's why i wonder
PetoKraus: anyway.... it needs gcc which is installed...
PetoKraus: and definately working.
redeeman: im afraid i cant help more than that, i haven't read the code
PetoKraus: :) that's ok
Deanjo: michaellarabel, can you please shorten the Timed LZMA Compression test? 35 minutes to an hour for each of the 3 runs is pretty excessive. http://global.phoronix-test-suite.com/?k=profile&u=deanjo-772-20424-2289
Deanjo: I'd hate to see it being ran on a atom or nano
michaellarabel: Deanjo: Probably
michaellarabel: Deanjo: Changed it to 256MB from 2GB
vincent__: I need some advice
vincent__: I have a 4870 x2
vincent__: and I am using the official ati catalyst driver 8.9
vincent__: and whenever I run a game that is heavy it seems to crash
vincent__: and funny effects with shaders
vincent__: and 16bit depth even when it says it is running 24bit
vincent__: color dept
vincent__: in Windows XP i get the same BS
vincent__: now this card has a minimum requirement of 650watt
vincent__: and I have a 650watt corsair PSU
^Azerthoth: problems that follow from OS to OS is indicitave of hardware problems
vincent__: yes but they are the same drivers
vincent__: both 8.9 catalyst
vincent__: i then upgraded to 8.10 on xp
vincent__: but I have a 650Watt PSU but also a 9950 amd phenom and 8gbRAM and a heavy gigabyte mootherboard that has a x3100 ati card onboard =x
vincent__: would it help to upgrade to a 1000watt PSU maybe?
vincent__: maybe this card doesn't get enough power?
^Azerthoth: that would fall into hardware yes?
vincent__: yeah im sorry I don't have enough knowledge to narrow the problem down
vincent__: and the thing is that I have had the exact same shader issues with my previous hardware... both being ATI and amd
vincent__: the funny shader thing is that, for example in doom3, when you move realy fast around the shaders turn green/purple... but when the screen is steady it is fixed =x
vincent__: and both XP and Kubuntu have 16bit color depth
vincent__: so I don't realy know if the problem is my hardware, the ati driver, or stability issues
vincent__: or a combination of it
vincent__: is there any advice you can give me to get me started somewhere?
^Azerthoth: start somewhere and start narrowing down
^Azerthoth: PSU seems a good as place as any to start
vincent__: yes I allready figured that part out before asking the question.... but PSU's with high efficiency cost a lot, and if something else fixes my problem it would help
vincent__: I did start googling before asking dumb questions tho ;)
maligor: I'd first check ram
maligor: since it's easy
maligor: vincent__, how do you figure it's 16bit?
vincent__: I could do that, but of all the problems I experience with my hardware, nothing seems to point at RAM
maligor: random program crashes would be ram indicative
vincent__: because er..... how do you explain that.... you know when you run in 16but color mode a 32bit color is formed by mixing 2 colors around a color?
vincent__: each pixel has a different color
maligor: lots of TN LCD panels do that
vincent__: nah thats impossible because of a friend of mine has the EXACT same LCD screen and he has a nvidia card and he doesn't experience it under kubuntu and I do
maligor: are you sure it's the exact same lcd?
maligor: same model doesn't mean it is
vincent__: uh.... it was bought at the same store, around the same time, and both look exacly the same, have the exact same specs, stikkers, etc
maligor: lots of manufacturers can switch panels inside the things
maligor: yes, still doesn't mean a whole lot
maligor: highly probable that they would be the same batch tho
vincent__: errrr i have a LG Flatron Wide 22 inch with 1680x1050 2ms responce time black and gray
vincent__: if that says anything :/
maligor: TN panel
maligor: the dithering shouldn't be so bad that it really annoys you tho
maligor: if it even does it
vincent__: yes a tn panel
maligor: tried switching to depth 16 and see what happens btw?
vincent__: it annoys
vincent__: oh no it cant be the pannel
vincent__: because the pixels remean the same when I drag a movie
vincent__: when paused
vincent__: at the exact same spots
vincent__: in 3d
vincent__: also with wobbly windows
vincent__: the pannel cant be that smart ^^
vincent__: I could try that.... ill write it down
maligor: using dvi or vga?
maligor: you could also try vga to see what happens if you have a cable
vincent__: yeah i have one
vincent__: ill try that too
vincent__: but the same 16bitt stuff happens when I switch to desktop effects in kde4 with a compaq non-ati pentium3 desktop crappy thing
vincent__: only way worse
maligor: oh, basic 2d doesn't do it?
vincent__: yes it does too
vincent__: not on that compaq machine but it does on mine
vincent__: tried fluxbox
vincent__: and same stuff happened
maligor: you haven't enabled weird options?
vincent__: I originaly thought the problem on the compaq was due to the small amount of ram on that onboard crap card
vincent__: just installed the driver
vincent__: same for xp
maligor: the specs says it can do spatial/temporal dithering for 24bit displays to show 30bit images
maligor: but beats me why that would be enabled
vincent__: specs of my ati card?
maligor: err? a non-ati machine does it too?
vincent__: yes and no
vincent__: nvidia doesnt do it
vincent__: onboard crap card of a compaq pentium3 only does it in 3d and ati does both :P
vincent__: but I didnt had that problem with my older ati card on this monitor now that i remember it
vincent__: that was with dvi too
vincent__: and i dont think that not just enough or not enough causes 16bit-like stuff
vincent__: i made a screenshot
vincent__: ill upload it and give you the link w8 a sec
vincent__: omg thats a thumbnail -_-
maligor: I can't see any dithering
vincent__: thats the correct one
vincent__: you can see it in the reflection under the windows
vincent__: and the wallpaper
vincent__: its a 1680x1050 image so make sure your browser doesn't resize it for you
maligor: you mean banding?
vincent__: http://en.wikipedia.org/wiki/Image:Colour_banding_example01.png <- that 78bit image
vincent__: in the middel
maligor: I can't see anything wrong with it
vincent__: you need to click the image for full screen
vincent__: on that website
maligor: the only thing it means is that the issue happens after the framebuffer tho
vincent__: do you look at it with a crt screen or a flatpanel
vincent__: i can imagine you cant see it with a crt
maligor: a flatpanel
maligor: you could see dithering justaswell in a flatpanel as a crt
maligor: mine is a S-PVA tho
maligor: dunno why it'd be limited like that tho
maligor: I mean specific to cards and use
vincent__: a crt? well it uses magnetics to bend 3 light sources to pixels... so i can image pixels going over each other
vincent__: yeah i don't know either
vincent__: from what i have seen nVidia cards produce better images than ati tho
vincent__: altho ati has a reputation of better images :S
vincent__: now wait... more correct images
maligor: it's non-relevant on dvi
vincent__: yup thats digital
vincent__: but from a rendering perspective... nvidia seems to get it more... right somehow
vincent__: ati cards render some things a little incorrect so it seems
vincent__: not as in artifacts but
vincent__: i cant really explain it
vincent__: for example... if you have motion blur in a racing game... the blur seems a little wierdish on ati cards and correct on nvidia cards
maligor: I'd have to say it's caused by the lcd tho
maligor: oh, shader program differences
vincent__: i guess
vincent__: but that could be because some devs used nvidia cards to design the game and then later on build in workaround for ati cards
vincent__: that produces somewhat crappy effects
vincent__: it mostly shows in Doom3, but id software uses nvidia for everything :P
vincent__: but is there a way to check if I have 8bit dithering or 24bit gradient stuff enabled?
vincent__: some kind of command or something?
vincent__: im still kinda newbish when it comes to linux :P
maligor: vincent__, you mean if you have depth 16?
maligor: cat /var/log/Xorg.0.log | grep Depth
vincent__: (**) fglrx(0): Depth 24, (--) framebuffer bpp 32 (--) Depth 24 pixmap format is 32 bpp
vincent__: I think i figured a way out
vincent__: to check it
vincent__: by changin my resolution
vincent__: and see if the dithering happens per pixel on my screen or per pixel onm the image send to the screen
maligor: just make it small enough, like below half
vincent__: no dithering on lower res
vincent__: when i press the button on the screen for the main menu it shows the menu in full ress and no dithering there
vincent__: that menu is transparent
vincent__: and showed dithering when on native res
vincent__: but not on low res
vincent__: and it can't be the graphics memory being too small because its 2 gb
vincent__: I took a look at the back of my screen
vincent__: its an LG Flatron Wide L226WTQ-SFS
vincent__: manufatured okt 2007
vincent__: it apears to be 24bit(16.7 milion colors) and DVI-D
vincent__: and it is a TFT active matrix
vincent__: or PN panel
vincent__: after zooming in on mu screenshot I saw that something was just rendered wierd
vincent__: and the some pixels are rendered dithered
vincent__: when zoomed in
vincent__: ok i nailed the dithering
vincent__: i HAVE a TN pannel
vincent__: and in order for it to display 24bit is to dither
vincent__: it can dither by quickly cycling pixel or by FRC(frame rate control)
vincent__: and I happen to NOT have that
vincent__: it's also combined by crack kde4 rendering
vincent__: which officialy sucks balls
vincent__: especially when it comes to svg
vincent__: which is all over the plasma desktop
Milyardo: So Deanjo: What do you think of the new Open-Suse community elected board?
Deanjo: They have some good peeps in there. Kind of sorry to see Andreas retire but some new blood will be interesting
Deanjo: I guess retire would be the wrong word, just took himself out of the race for this election.
Milyardo: How long until Deajo runs for a positon :)
Deanjo: Ahh it will be a while before I run for that
Deanjo: When you have guys like Pascal running, I'm a relative unknown :D
