i just updated from x11-base/xorg-server-1.6.5-r1 to x11-base/xorg-server-1.7.6 on amd64, and besides the keyboard stopped working (which i could fix by re-emerging x11-drivers/xf86-input-evdev manually) my dual monitor setup (xinerama, nvidia drivers) suddenly has some problems. my screens are not of the same size (1440x900 left of 1280x1024 aligned to bottom), and when i move the mouse to the secondary 1280x1024 screen, in the upper region (presumably in the upper 124 pixels), the mouse get invisible and also appears on the buttom line of that screen - which is a really wired behaivor.

Sounds like the bug i reported today: http://bugs.gentoo.org/show_bug.cgi?id=315985
Maybe also related to bug 291620
meanwhile, i found that i could workaround this problem by aligning both screens to top and setting relativ ("Left Of") positions instead ob absoult ones. however, it's still a bug, since it limits funtionallity and renders a valid xorg-configuration unusable. ( i also found out that i have a flicker problem upon (suspend to ram + ) resume, which did not occur in xorg 1.6 - but this is another bug. )

(In reply to comment #3) > Maybe also related to bug 291620 I doubt it, this bug is a little older, while this one seems to be related to 1.7.6 Please file a bug upstream [1] and paste the URL here so we can track the issue directly.
