In fact, I'm pretty sure the problem comes from there as screenshots are garbled and so does a few more things. I may have time to dig this up, where should I start, is there some documentation on the NVS 140M ? Where is the gart2vram code located ? Do you have any idea of where could be the problem ? If you really think that's UTS/DFS, edit nouveau_exa.c and disable them (change the UTS/DFS functions to return FALSE, that'll trigger fallbacks to sw copying). Stephane In fact, following your advice triggers a lot more corruption. So, the problem comes from elsewhere. My corruption problem seems like there is a codepath that copy a pixmap with wrong height and width. I'll dig into it. I'll keep in touch.

[Nouveau] uevent support in nouveau DDX
Hi, uevent support was added to the nouveau DDX in a recent commit. A test is made in configure.ac for libudev being present but there is no minimum version. I have had problems with this as I am using Fedora 11 which has udev-141 in it. This version does not support all of the functions required by the DDX and will crash Xorg. At least this function is missing: udev_monitor_filter_add_match_subsystem_devtype I don't know when this was added to udev, but it was definitely after 141. In the mean time, I will endeavor to fudge the configuration so that it doesn't think that udev is installed. Hopefully this will result in a DDX that doesn't crash. I'm also going to try setting up a partition with Fedora 13 to see what happens with that.

[Nouveau] [Bug 27832] New: Early versions of libudev cause crash
https://bugs.freedesktop.org/show_bug.cgi?id=27832 Summary: Early versions of libudev cause crash Product: xorg Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: critical Priority: medium Component: Driver/nouveau AssignedTo: nouveau@lists.freedesktop.org ReportedBy: rjgle...@bellsouth.net QAContact: xorg-t...@lists.x.org Created an attachment (id=35286) -- (https://bugs.freedesktop.org/attachment.cgi?id=35286) Patch to configure.ac to check libudev version = 142 It appears that at least version 142 of udev is required to properly support the recently added uevent code. Haven't tested with 142 because I don't want to mess up my distro Fedora 11. This only has 141. However, everything is usable if the driver thinks you don't have udev at all. Hence the attached patch.
