Ah I just found out that changing the screen number on the configuration changes the output of glxinfo. So if I have Screen 0 "screen-nv" Screen 1 "screen-ra" LeftOf "screen-nv" glxinfo gives me "nouveau" for both screens. But if I have Screen 1 "screen-nv" Screen 0 "screen-ra" LeftOf "screen-nv" glxinfo gives me "Gallium 0.4 on AMD SUMO" for both screens. First report was with mesa-7.11 but after an update to 8.0.1 I get the same thing. What's the output of glxinfo if you set DISPLAY=":0"? Does it list both screens one after the other?
Also, please try "glxinfo -b" with DISPLAY=":0.0" and ":0.1".
Otherwise, I think the bug might be in glxinfo itself.
Here's the code to loop over the screens:
numScreens = ScreenCount(dpy);
print_display_info(dpy);
for (scrnum = 0; scrnum < numScreens; scrnum++) {
For display=":0.1" I have a feeling that numScreens = 1 and scrnum is always zero so we're only querying the 0th screen.
I'll attach a patch to glxinfo for you to try.
Created attachment 58147 [details] [review] try to fix screen indexing in glxinfo Can you try applying this patch to glxinfo and see if it helps? glxinfo is in the Mesa demos repository in src/xdemos/glxinfo.c Ok, So when I start "DISPLAY=:0 glxinfo" I get both screens first the nouveau screen (0) then the radeon one (1). when I start "DISPLAY=:0.0 glxinfo -b" I get "33" when I start "DISPLAY=:0.1 glxinfo -b" I get "33" with the patch applied when I do "DISPLAY=:0.0 glxinfo" I get both screens listed (correctly just as before when I used DISPLAY=:0). In fact it is nearly the same output as "DISPLAY=:0 glxinfo" except for the first line where after "name of display" it shows ":0" or ":0.0" Was it intended ? (personnally if I ask for one specific screen I don't care about the other ones... but it is true that when starting glxinfo without changing DISPLAY variable it gets as default value the current screen I you can't tell if there are others, so I guess it is ok this way) -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 58132 [details] display-related file in /etc/X11/xorg.conf.d/ that sets up the multi-head After hitting #47064 I decided to play with my nvidia card and the radeon IGP I have in my new system. So I set xorg configuration up so that I have a desktop spanning both cards and when I ask glxinfo for both displays I get the same answer... I would expect one to be radeon and the other nouveau not both nouveau... I don't know if it is a bug in X in glxinfo or in mesa, if I can be of any help to find out tell me.
