Default X server 1.12.1 instantly crashes on connection of HDMI monitor on 9600M GT

My Iiyama ProLite E2773HDS works perfectly on Windows 7, but whenever I just plug it in via HDMI on Linux (x64) the X server immediately crashes, regardless of my xorg.conf present or none at all. If I try to log in from ngetty (to xmonad) the desktop sometimes flashes for less then a second, then it's back to ngetty again.

The same crash will happen one time after X is started without this second monitor, thereafter at least the primary one works again.

Aside from the memory positions, the backtrace in Xorg.0.log is always the same.

xorg-server 1.12.1, nvidia 295.40, glibc 2.15 (w/ Arch Linux patchset -10), kernel 3.3.2, 9600M GT
Occurred also with previous versions.

Attached nvidia-bug-report created with no xorg.conf present (used X server 1.12.0.902, kernel 3.3.1).

Any comments, devs? This situation is really lousy, I'm doing most of my work with Linux.

edit: Explicitly disabling composite changes nothing.

Explicitly disabling Xinerama doesn't change anything either.

However, the display works fine with nouveau. Thus I'm tempted to say that this indeed is a bug in your driver, or at least the interaction between it and xorg (d'uh).

(Won't use nouveau though since I need vdpau/etc. acceleration and power management. But sweet goodness, KMS makes the console look so much nicer on a FHD display.)

edit: With no relevant source changes, same for X server 1.12.1 and kernel 3.3.2.

With both (and only both) RenderAccel set to False and the first Metamodes "1920x1080,NULL;" the X Server will at least properly start (and still crash if the HDMI cable is plugged in/out).

However, it shows a corrupted oversized image (example) if there's another metamode given, and nvidia-settings will not detect the second display in "X Server Display Configuration", though it does list it as DFP-1 under GPU 0. Also, that monitor will remain in standby.

edit: RenderAccel may remain true, apparently.

Correction: The monitor is listed properly in Display Configuration, I just had to actually select it in "Model:". The crash then occurs once it's enabled, regardless of the chosen resolution (eg Auto).

If just tried it with a DVI:HDMI (monitor:laptop) cable, and while the crash is exactly the same if the cable if plugged in/out with X running (same with the different monitor it belongs to), this way the display at least works.

I do not want this workaround to become permanent, though.

Yay, thanks.

Is it possible for unprivileged users like me to check that bug id's progress?

Gone with 302.07 (using a fresh X Server compile from git). Hotplugging works fine, too.
