I have a system with a Magtrox Millennium G450. The start of X fails if the module matrox_w1 is loaded with: [ 44926.708] (II) MGA: driver for Matrox chipsets: mga2064w, mga1064sg, mga2164w, mga2164w AGP, mgag100, mgag100 PCI, mgag200, mgag200 PCI, mgag200 SE A PCI, mgag200 SE B PCI, mgag200 EV Maxim, mgag200 ER SH7757, mgag200 eW Nuvoton, mgag200eH, mgag400, mgag550 [ 44926.710] (++) using VT number 7 [ 44927.037] (EE) mga: The PCI device 0x525 at 01@00:00:0 has a kernel module claiming it.

I have the feeling that there was no conflict between matrox_w1 and X11 with older linux versions.
(In reply to comment #0) Hi Juergen, I have some points to consider: 1.) Did you follow these instructions: http://en.gentoo-wiki.com/wiki/Matrox_Card? In the case your answer was yes, please attach in this bug your xorg.conf and your Xorg.0.log (/var/log/Xorg.0.log). 2.) Please check if your kernel framebuffer interface is enabled in the device section of the xorg.conf. Option "UseFBDev" "true" 3.) If you have compiled it as a module, you should add *matroxfb* to your /etc/conf.d/modules file.
Hi Mario, it seems, that I switched from matrox to vesa framebuffer going from kernel-x86-3.4.0-gentoo to kernel-x86-3.4.4-gentoo: root@cheetah:/usr/src(49)# egrep "/kernel|[^#]append=|[^#] vga=" /etc/lilo.conf ... image = /boot/kernel-genkernel-x86-3.3.1 append="video=matroxfb:vesa:0x11C domdadm dolvm real_root=/dev/md125" image = /boot/kernel-genkernel-x86-3.3.3 append="video=matroxfb:vesa:0x11C domdadm dolvm real_root=/dev/md125" image = /boot/kernel-genkernel-x86-3.3.4-gentoo append="video=matroxfb:vesa:0x11C domdadm dolvm real_root=/dev/md125" image = /boot/kernel-genkernel-x86-3.4.0-gentoo append="video=matroxfb:vesa:0x11C domdadm dolvm real_root=/dev/md125" image = /boot/kernel-genkernel-x86-3.4.4-gentoo vga=0x31B append="domdadm dolvm real_root=/dev/md125 acpi_enforce_resources=lax" image = /boot/kernel-genkernel-x86-3.5.0-gentoo vga=0x31B append="domdadm dolvm real_root=/dev/md125 acpi_enforce_resources=lax" image = /boot/kernel-genkernel-x86-3.2.14-rt24-rt24 append="video=matroxfb:vesa:0x11C" There was any reason that I switched from matroxfb to vesafb, but I forgot the reason. I will try again with matroxfb.
Yes I removed FB_MATROX from linux-3.4.4: root@cheetah:/usr/src(7)# diff linux-3.4.0-gentoo/.config linux-3.4.4-gentoo/.config | grep CONFIG_FB < CONFIG_FB_DDC=m < # CONFIG_FB_BOOT_VESA_SUPPORT is not set > # CONFIG_FB_DDC is not set > CONFIG_FB_BOOT_VESA_SUPPORT=y < # CONFIG_FB_SYS_FILLRECT is not set < # CONFIG_FB_SYS_COPYAREA is not set < # CONFIG_FB_SYS_IMAGEBLIT is not set > CONFIG_FB_SYS_FILLRECT=m > CONFIG_FB_SYS_COPYAREA=m > CONFIG_FB_SYS_IMAGEBLIT=m > CONFIG_FB_DEFERRED_IO=y < # CONFIG_FB_VESA is not set > CONFIG_FB_VESA=y < CONFIG_FB_MATROX=y < # CONFIG_FB_MATROX_MILLENIUM is not set < # CONFIG_FB_MATROX_MYSTIQUE is not set < CONFIG_FB_MATROX_G=y < CONFIG_FB_MATROX_I2C=m < CONFIG_FB_MATROX_MAVEN=m > # CONFIG_FB_MATROX is not set > # CONFIG_FB_TMIO is not set I added it again to linux-3.4.5, but now X fails to start with both linux versions (with vesa and with matrox frambebuffer) with: [ 327.610] (II) LoadModule: "mga" [ 327.611] (II) Loading /usr/lib/xorg/modules/drivers/mga_drv.so [ 327.621] (EE) Failed to load /usr/lib/xorg/modules/drivers/mga_drv.so: /usr/lib/xorg/modules/drivers/mga_drv.so: undefined symbol: MGAStormSync [ 327.621] (II) UnloadModule: "mga" [ 327.621] (II) Unloading mga [ 327.621] (EE) Failed to load module "mga" (loader failed, 7) [ 327.621] (II) LoadModule: "evdev" [ 327.621] (II) Loading /usr/lib/xorg/modules/input/evdev_drv.so [ 327.621] (II) Module evdev: vendor="X.Org Foundation" [ 327.621] compiled for 1.12.99.902, module version = 2.7.1 [ 327.621] Module class: X.Org XInput Driver [ 327.622] ABI class: X.Org XInput driver, version 18.0 [ 327.622] (EE) No drivers available.

Hey Juergen, I'm just not able to reproduce this bug so far. But I checked this message below (Xorg.0.log) and looks like that are not compiling correctly because some modules is not enabled in the xorg.conf. [ 546.412] (EE) Failed to load /usr/lib/xorg/modules/drivers/mga_drv.so: /usr/lib/xorg/modules/drivers/mga_drv.so: undefined symbol: MGAStormSync Maybe a solution is: 1.) Download the driver from the vendor 2.) Copy it to /usr/lib/xorg/modules/drivers/ 3.) Try again README: http://en.gentoo-wiki.com/wiki/X.Org/Dual_Monitors/Matrox I saw an interesting post about this issue too, Please take a look in the link below: http://forums.gentoo.org/viewtopic-p-7101502.html
Juergen, or other people with the same issue, if you still experience then please try the previous comment 7 and let us know whether that helped. Relevant link explaining the issue: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+bug/1044797
