Nightwulf|work: hi all
girrr: I've been experience som rendering anomalities on the HD4850 since switching from two older monitors connected through vga to a pair of new ones using dvi.
girrr: Se picture: http://picard.hgo.se/~kristian/anomalities.jpg
girrr: I've also noticed that one of the monitors picture can walk a pixel or two to the right or left
Soul_keeper: girrr, make sure you have the right sync ranges
Soul_keeper: don't wanna fry your brand new monitors ...
girrr: Soul_keeper, how can I assure this?
Soul_keeper: girrr, go to the manufacturer's website and look up the specs
Soul_keeper: put the proper horizontal and vertical sync ranges in your /etc/X11/xorg.conf file
girrr: Soul_keeper, Ok, found them... thanks
Soul_keeper: np
girrr: Soul_keeper, Btw, are the radeonhd driver using these or will it replace them with values read from edid?
Soul_keeper: the safest bet is to specify them yourself
Soul_keeper: that way you don't have to rely on code trying to guess them
Soul_keeper: specially with a new monitor
girrr: Soul_keeper, That's true...
girrr: I'm going to restart my X session and se if the anomalities disappears
girrr: brb
girrr: It didn't seem to help
girrr: The monitor says that the horz freq is 74.9kHz and vert freq 60Hz
girrr: The specifications says 30.0 - 92.0 for both horizsync and vertrefresh when connected through dvi
Daemonik: What's the status of the RadeonHD driver, is AMD supporting their own hardware by having one of their people work on the RadeonHD driver? If not, why not?
adamk: Well, they are definitely funding development of the driver. I do not know if anyone from AMD is actively working on it.
Daemonik: adamk, What are they doing to fund it?
Daemonik: Right now I have to make a decision to buy 30 motherboards for diskless workstations that will boot a Gentoo system over the network. Intel's GPUs are excellent (as you can actually use the damn things), are AMD's chips usable?
Daemonik: I would think a company as large as AMD would know better than to lock themselves out of the corporate desktop consolidation market.
yangman: AMD doesn't fund radeon/radeonhd efforts directly, but they've thrown resources behind things that make it possible
adamk: All r100-r500 GPUs have quite usable open source drivers. 2D + 3D.. modesetting, textured Xvideo, RenderAccel via EXA (and XAA on r100-r300 GPUs).
adamk: xrandr1.2 support.. I think tv-out might be problematic.
Daemonik: adamk, But all the motherboards I'm seeing here on NewEgg are RadeonHD 2200s and up.
adamk: r600 has 2D modesetting only at the moment. The specs are still under NDA, but are actively being vetted for any IP issues. Rumor has it that 2D/3D acceleration will be available soon (within months) but I can't say if that's accurate.
yangman: realize that if you're talking about the state of things right now, you need to be running snapshot code from development tree to get good support
adamk: Well I'm not sure I'd call Mesa 7.1 "snapshot code"
Daemonik: yangman, So I should put very little faith in any AMD hardware right now, and continue to tell clients to buy hundreds of intel motherboards with Intel GMA X3100s and hundreds of Intel processors to go with them when they want to consolidate their desktops.
yangman: mesa isn't relevant at all. there's no 3D
adamk: yangman, For r100-r500 there is.
yangman: adamk: but aren't we talking about HD2200 and up? ;)
yangman: Daemonik: depends on the need. does your client really need mid/high range 3D support in all the workstations?
adamk: yangman, Just a few seconds earlier, I had been talking about r100-r500 and you didn't specify what you were talking about. It is not unreasonable for me to not realize you were being specific to r600.
Daemonik: yangman, Compiz for every user. Shift Switcher, Expo, Scale. Compiz runs locally, apps run remotely. This is one of the major points of user experience.
Daemonik: adamk, Nope.
yangman: adamk: fair, but I was also refering to the drivers specifically; what I said is true for radeonhd
adamk: Daemonik, The the 2200s are out of the question if you need them now, and you can't/won't use fglrx.
Daemonik: adamk, These are business machines. No blobs.
adamk: Then you have your answer.
Daemonik: AMD doesn't sell hardware, it sells paperweights.
adamk: Daemonik, If you are going to troll, take it somewhere else.
adamk: No one here can do anything about AMD's speed at producing specs or funding, or do anything about your opinion.
Daemonik: adamk, Why should any one here be doing anything about it? It's AMD shooting itself in the foot.
Daemonik: adamk, Perhaps I should rephrase: They make/sell the hardware, they have a responsibility not to blackmail the people they sell it to.
adamk: And they appear to be doing pretty well at fulfilling their responsibility. The amount of open source support for AMD GPUs has grown tremendously in the last few months since AMD has started releasing specifications.
adamk: But bitching about the fact that they are apparently going slower than you'd like in a channel full of people who use AMD hardware (and many who develop drivers for AMD hardware) isn't tactful (and that's me trying to be tactful) :-)
Daemonik: adamk, Why aren't their own engineers working directly on it?
adamk: How should I know.
marcheu: because engineers cost money
agd5f: Daemonik: I work for AMD and I'm working on open source support
Dead2: Remember that this driver was (and correct me if I'm wrong) not AMD's work from the start.
Daemonik: Dead2, Under the presumption they want their hardware to be relevant, they really, really, should get involved.
Dead2: Daemonik: They are cooperating and helping this 3rd party driver, and they should not take over the design of it.
agd5f: It takes years to design chips and back when the current chips were being designed, open source wasn't in the plan, so now all the due diligence has to be done to get specs written and out.
Daemonik: Dead2, Why aren't they working on it directly? agd5f They don't have their own specs? "IP"? They can't buy their own hardware so they can actually sell it?
adamk: Daemonik, They don't necessarily own every bit of IP in their chips.
adamk: They may have licensed some of it from other companies and can't legally distribute the specs without first removing those parts.
Dead2: Daemonik: Of course they have the specs. But likely not in a public-friendly format. So they have to hire technical writers that can put the specs into a presentable format that will inspire and help developers. Also they have to make sure they dont release specs for things that they do not own or have the rights to release.
Dead2: Those things take a lot of time and effort
Daemonik: Dead2, They're paying these people a lot of money to do this right? Hey marcheu, don't engineers cost money?
Dead2: Daemonik: correct, so that should answer your question regarding whether they are helping develop this driver.
marcheu: Daemonik: what they're doing is the right long-term solution
adamk: Releasing the specs is much better than paying internal developers to work on a driver that only they can work on :-)
Daemonik: marcheu, With the long term result of a fully open fully functional driver with full 3D acceleration for _all_ cards, right??
agd5f: Daemonik: that's the plan
Dead2: Good documentation is the single most important thing you can have when developing drivers for hardware. Not even the hardware itself comes close to being as important.
Daemonik: agd5f, According to them or their implications?
agd5f: Daemonik: according to AMD. I work for AMD and am doing most of the work on this
Daemonik: agd5f, Good. Well then I'll be indirectly sending a ton of money in your direction in the future.
agd5f: Daemonik: great!
adamk: Woohoo.
adamk: How come no one sends me a ton of money, either directly or indirectly?
Daemonik: I'm not an Xorg developer (obviously), but as far as I understand Intel produces the driver without being completely open about the specs. The driver works great, but if AMD matches intel with not only a working driver but completely open specs (or less closed, thus less evil)
Daemonik: I'll be buying AMD.
Daemonik: adamk, Participate in replacing the proprietary NX server, freenx is way behind, there are companies that want this (one being a friend of mine wants me to help him start).
Daemonik: It's all about the "vertical market".
Agiofws: hi
Agiofws: could someone please tell me if this is a hardware or software problem ? www.imagebin.org/25756
Agiofws: the strange thing is that IT HAPPENS on on my lapis LCD on the second screen everything is ok
Agiofws: my card is ati 2600HD
