    Some questions about eyefinity

    Hi all,

    A bit of background to begin, i currently run 2 LG W2252(1680x1050) 22" LCDs via twin-view on a 7600GT. I'm looking at upgrading my PC specifically upgrading to a ATI 6xxx card to take advantage of triple-head(I will be also purchasing another LG LCD). For software i'm running a gentoo ~amd64 system with xfce 4.7.

    I like the way twin-view works, it allows me to have a spaned display for my desktop and lets my WM know where the monitor borders are. It also allows me to turn off one of the monitors(selectively via meta-modes like 1680x1050, NULL or NULL, 1680x1050) if i need to run a game or other full screen application on just one monitor. Generally i do this in a separate X session while keeping my spaned desktop session running.

    Is eyefinity a similar technology to twin-view? Can i selectively turn monitors off to run just a single monitor for something like xbmc to run on the central screen? (An after thought was that i could possibly just use a second x configuration file that only turns on the center monitor as i almost always load xbmc into its own X session, this is messy however and i'd prefer the option to control it via xrandr or similar. even if i could just change from 5040x1050(l+c+r) to 3360x1050(l+c) to 1680x1050(c) and then smaller 4:3 resolutions on the center monitor via xrandr i'd be happy)

    I assume eyefinity allows full 3d acceleration across the whole span? So i can run ultrawide games in wine?

    Does eyefinity like twin-view let x know that it is creating a span, so that x is able to inform the WM where things like monitor borders are?

    Cheers,
    Novae

    11.2 was better, i was able to play LoL @ 5040x1050 at a decent(although not great compared to windows) frame rate. However i am still completely unable to play EVE. Ultimately i have no idea if this is an issue with the blob driver or some other competent of my system however EVE was happy to run with the current software configuration on a NVIDIA based system which makes me suspect its something to do with the driver.

    I've decided to try the latest version of the OSS driver as it has just been given S3TS support which should allow it to run EVE with proper textures.

    Here's a link to the gentoo forums details my current issues, http://forums.gentoo.org/viewtopic-p...7.html#6587067

    Are you experiencing the known audio bug in wine? See the page on winehq.org for eveonline client for a workaround (I just disable audio altogether, remember to also disable eve voice AFTER logging in but before choosing a character!). Not resolving this results in a hang at some point after choosing a character. There's also some help from ati users in the EVE-O linux thread.

    It could also be related to the new char portraits failing. See this workaround.
    I dont think it was related to either of these, as disable sound made no difference and the workaround for the portraits also did not help.

    Anyway, i've been gaming in windows for the past few weeks, waiting for 11.2 to come out and hopefully fix some of my issues as i hot a brick wall. Just building it now and we'll see how it goes.

    Heh. So far, they've been able to limit the mouse to the visible area (good) but desktop icons can still be moved outside (bad). Apparently, the latter is a WM issue and should be fixed downstream.

    I think this bug was first reported back in 2002 but noone really started working on it until Ubuntu users started complaining...

    This can be useful for some but of course the ultimate is to have a properly unified desktop.
    I have to do this at work with my two quadro cards and four monitors (2 twinview, 2 mirrored separate X screens). There's simply no way to have accelerated desktop with more than 1 nvidia gpu. AMD is miles ahead on this front.

    I had problems with amdcccle initially not writing to /etc/X11/xorg.conf, despite proper root auth. I ended up just saving the amdcccle generated config to a user dir, then manually replacing /etc/X11/xorg.conf.

    I was able to get WoW to run, albeit in a separate X session, at 5040x1050 with highest settings and it seemed to run fine. But i have been completely unable to get EVE to run correctly, with it generally locking up at one of the login screens and often causing my system to become completely unresponsive requiring a hard reset.

    Can anyone point me to any good guides about the fglrx driver, preferably not ubuntu based guides as they rarely do want i require under gentoo?

    Yes, I like those "full screen applications" too.
