Created attachment 143972 [details] /etc/X11/xorg.conf This /etc/X11/xorg.conf has to be readed carefully about one point. You will have to focus on head called Screen_1_-1_scr that is using the device MGA_450_s2. You will read that I am using driver vesa for the second head; this will lead to the first coming Xlog. In this configuration, you will see that X does not report anything about the VESA head. That's the point making the bug close to bug 194515 . Since the card is a simple PCI brige, the card SHOULD be usable with vesa driver; and it fact, using the vesa driver works perfectly well with head 1; but not at all with heads 2, 3 and 4. - no message about why it's not used at all *** NB: this is the 6th (4th I report) bug I meet with X-1.4 where a feature is broken and it does not say why, and not even the fact that the feature is disabled. I still ask for hard mask against X 1.4: - too easy to crash - does not respect conf file (video layut, keyboard and mouse config: see for example bug 204128 that is easily met with X 1.4, and not with 1.3) - never say or warn it will behave a different wat than asked in the conf - breaks back compatibility, and does not say it - breaks many things in xinerama - breaks many things in DRI/DRM (even on single head) Created attachment 143973 [details]

log when using vesa driver
Created attachment 143974 [details]

When using tis section:
Section "Device"
Identifier "MGA_450_s2" # head 2 is VGA
Driver "mga"
BusID "PCI:2:4:0"
EndSection
instead of vesa, the problem is différent: X loads the 5 heads asked for; second MGA45x get loaded, and is part of the desktop. When I specify 1280x1024 as desktop, the monitor claims the frequency is out of range (using the same monitor and conf on any other card produce a nice result) (happens the same wat on any monitor I will put on any heads 2, 3 or 4 when I activate them). With lower resulotion, the screen starts, and shows light gray image, with vertical dark lines. In the best case I can get the cursor on it, and the mouse appears as a very big black square: image does not reflect at all the desktop background, does not vary when trying to put windows in ...
So, in the best cas, I can get monitor show garbage, not related in any way with what should be on (it's not a shuffled image based on any things it should show as happen on old box mixing several video cards, or AGP NV driver bugs of the old time).
And, I remind that this happens exactly the same whay even when the G45x4 is the only video card in the machine: this is NOT an interaction with other cards.
I complain against 2 points:
- feature broken
- X not reporting that feature is to be broken (missing error message)
