<1> ati's multihead is somewhat different from xinerama
<1> which is what system-config-display will set up
<0> http://pastebin.ca/125521
<0> i want resolution on both things to be 1280x1024
<0> and i want big desktop mode
<0> the only problem is, the old big desktop mode screwed up when you hit "maximize"
<0> it did it across both screens
<0> which i DON'T want
<1> yeah, that's annoying
<0> does it still do that?
<1> i think so, though i haven't tried multihead
<0> :(
<0> that's one of the reasons i had ditched ati before
<0> that's the most annoying thing ever
<0> and makes multi head useless
<1> well, back up your current xorg.conf and just change the Driver fields from radeon to fglrx
<1> though i don't think that'll work :/
<0> ok
<0> let me install epic console irc:)
<1> i don't think fglrx can emulate xinerama
<1> but i could be wrong
<2> Actually it does have pseudo-Xinerama in the last two versions
<1> oh, cool
<0> is fglrx's performance far better than radeon driver's?
<1> with opengl, yes
<0> Albatorsk: really?
<1> 2d is probably on par or worse than the oss driver
<0> the opengl with radeon, at least for this card, seems to be very slow
<1> yeah, it's mesa unaccelerated
<0> hey straw
<0> so what do i do, restart X now?
<1> reboot
<0> wait, do i change xorg.conf to use fglrx first?
<0> then reboot?
<1> make sure you have a backup xorg.conf so you can boot to a console and get X running again if you have problems
<1> Ediehow: yes
<1> change *just* the Driver entries to fglrx for now
<0> ok, it seems to be working
<0> but my glxgears performance is HORRIBLE
<1> try fglrxinfo
<0> 653 frames in 5.4 seconds = 121.682 FPS
<0> 684 frames in 5.3 seconds = 127.935 FPS
<0> 570 frames in 5.1 seconds = 111.810 FPS
<0> 586 frames in 5.3 seconds = 110.532 FPS
<0> 700 frames in 5.8 seconds = 120.634 FPS
<0> 708 frames in 6.0 seconds = 118.160 FPS
<0> Xlib: extension "XFree86-DRI" missing on display ":0.0".
<0> display: :0.0 screen: 0
<0> OpenGL vendor string: Mesa project: www.mesa3d.org
<0> OpenGL renderer string: Mesa GLX Indirect
<0> OpenGL version string: 1.2 (1.5 Mesa 6.4.2)
<2> Ok, I think I see the problem ;)
<0> and the display on second monitor is screwed up
<0> and the mouse pointer when on second monitor is screwed up too
<0> i need resolution on both screens to be 1280x1024
<1> try Xorg :1 -scanpci
<1> and paste the first line containing 'ATI Technologies Inc'
<0> the second monitor is samsung 914v syncmaster
<0> (1:0:0) unknown card (0x1002/0x0602) using a ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]
<0> (1:0:1) unknown card (0x1002/0x0603) using a ATI Technologies Inc RV370 [Radeon X300SE]
<3> Lastly, and remember you heard it here, AMD is strongly considering open-sourcing at least a functional subset of ATIs graphics drivers. Its time for X Window System, OpenGL, and client virtualization for which ATI binary drivers arent available to escape the ghetto of the 1980s-era framebuffer. And what a boon for PR. If AMDs graphics cards were the only ones with open device drivers, it might affect a buying decision or two.
<1> Ediehow: open your xorg.conf and add BusID "PCI:1:0:0" to the Videocard0 device section
<0> done
<1> Ediehow: and Screen 0
<0> straw: the screens are lined up right
<0> this is already under videocard1
<0> BusID "PCI:1:0:0"
<0> dont i need to set the refresh rates somewhere?
<1> in Section "Screen", Identifier "Screen1" change Modes "800x600" to Modes "1280x1024"
<0> k
<0> ok, that's it?
<1> we want to use the same busid for both sections
<0> should i comment out horiz rate and stuff?
<0> so to use ddc?
<1> actually, yes
<0> ok
<0> restart X now?
<1> you may want to add Option "PreferredVRefresh" "60" to both device sections as well, since they look to be lcds
<0> both are lcds
<0> but is that setting too low?
<0> they are not same monitor
<1> 60 is usually the desired refresh for an lcd
<0> ok
<0> restart X now?
<1> yes
<0> hi
<0> yay
<0> how do i fix gl now?
<1> export LIBGL_DEBUG=verbose
<1> and run fgl_glxgears
<0> Using GLX_SGIX_pbuffer
<0> Xlib: extension "XFree86-DRI" missing on display ":0.0".
<0> X Error of failed request: BadMatch (invalid parameter attributes)
<0> Major opcode of failed request: 142 (GLX)
<0> Minor opcode of failed request: 5 (X_GLXMakeCurrent)
<0> Serial number of failed request: 30
<0> Current serial number in output stream: 30
<1> i'll bet accclerated ogl isn't supported with xinerama
<0> hmm
<0> man, the performance when playing mpgs is horrible
<1> aticonfig --overlay-type=Xv
<0> how do i determine what it's using now?
<1> aticonfig --overlay-on=0
<1> or aticonfig --overlay-on=1
<0> aticonfig --overlay-type=Xv
<0> Warning: Option 'VideoOverlay' doesn't affect running session.
<0> Warning: Option 'OpenGLOverlay' doesn't affect running session.
<0> Using /etc/X11/xorg.conf
<0> Saved back-up to /etc/X11/xorg.conf.fglrx-4
<0> aticonfig --overlay-on=1
<0> Warning: Failed to set hardware overlay to head 1 immediately.
<0> Using /etc/X11/xorg.conf
<0> Saved back-up to /etc/X11/xorg.conf.fglrx-5
<0> do i do it for 0 and 1?
<1> no, pick one
<0> i ran it for 1
<1> then Xv will work on that display
<0> glxinfo says drm is not running
<1> restart X
<1> accelerated ogl will probably not work with xinerama
<0> i cant have it on both?
<0> i mean i can't have xv on both?
<1> no, i don't think so
<0> holy cow
<0> that's why i ditched my ati card last time:O
<1> though i'm not very familiar with multihead and ati
<1> Albatorsk, care to comment?
<2> Sorry, wasn't paying attention. I'm cooking dinner :P
<2> How about a quick recap?
<1> is Xv limited to one head?
<2> Yes
<1> and will accelerated ogl work with a xinerama layout
<2> Yes, as long as you're using the "big desktop" feature, and not real Xinerama.
<2> Big desktop with pseudo-Xinerama should be just fine.
<1> does big desktop still maximize a window across both heads?
<0> ok, so as of now, i should have xv on display 1?
<0> is it possible to get gl on one head and xv on another?
<2> straw: No, not if pseudo-Xinerama is enabled. And I think it is enabled by default.
<0> Albatorsk: how do i determine if i am using pseudo xinerama?
<0> yeah, i need maximize to not go across both heads
<0> here is my xorg.conf
<2> Ediehow: Check your Xorg log. If you can't find anything, post it on pastebin.com and we'll have a look
<0> i have xinerama set to on
<2> Ok, post your entire xorg.conf and log.
<2> If you're using the "real" Xinerama method with two screens, two monitor sections etc. it's normal for OpenGL not to work.
<1> well, i've got to go out for a bit. good luck, Ediehow
<2> At least that used top be the case.

<0> i usually watch mythtv on screen 1
