Created attachment 73298 [details] Log file containing backtrace Hi, On a fresh install of Ubuntu 12.10, using the (default) nouveau graphics driver, I am able to crash the display manager by moving any window outside the screen area. Using other graphics-drivers (nvidia proprietary), there are no problems with having windows outside the screen area. I've attached a the Xorg.0.log logfile which contains a backtrace. My graphics card is an NVidia GeForce GTX 660 Ti Amp Edition. Please let me know if you need any other log-files from the system. Thanks
There is no backtrace in this file. If it crashes in NVRefreshArea, then this is already fixed in xf86-video-nouveau 1.0.3 (you are using 1.0.2)

you're right, I must have chosen the wrong file. Sorry about that. This is what I'm referring to: [ 52.829] (EE) Backtrace: [ 52.829] (EE) 0: /usr/bin/X (xorg_backtrace+0x36) [0x7ffc28073b76] [ 52.829] (EE) 1: /usr/bin/X (0x7ffc27ecb000+0x1ac9a9) [0x7ffc280779a9] [ 52.829] (EE) 2: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7ffc271f1000+0xfcb0) [0x7ffc27200cb0] [ 52.829] (EE) 3: /usr/lib/xorg/modules/drivers/nouveau_drv.so (0x7ffc24cd1000+0x102b1) [0x7ffc24ce12b1] [ 52.829] (EE) 4: /usr/lib/xorg/modules/libshadowfb.so (0x7ffc23c69000+0x3af3) [0x7ffc23c6caf3] [ 52.829] (EE) 5: /usr/bin/X (0x7ffc27ecb000+0x51a4b) [0x7ffc27f1ca4b] [ 52.829] (EE) 6: /usr/bin/X (0x7ffc27ecb000+0x55a91) [0x7ffc27f20a91] [ 52.829] (EE) 7: /usr/bin/X (0x7ffc27ecb000+0x4456a) [0x7ffc27f0f56a] [ 52.829] (EE) 8: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xed) [0x7ffc25e7676d] [ 52.829] (EE) 9: /usr/bin/X (0x7ffc27ecb000+0x448ad) [0x7ffc27f0f8ad] [ 52.829] (EE) [ 52.829] (EE) Segmentation fault at address 0x7ffc23c70000
Adding to the information originally posted. The crash only occurs when moving a window down below the bottom of the screen area, not right or left. My graphics card is produced by Zotac. I intended to write: Zotac GeForce GTX 660 Ti Amp Edition, as the graphics card. I've been trying to install a version 1.0.3 driver to see if that fixes the issue, but so far I can't find it (nouveau.freedesktop.org responds with a HTTP 503 Service Unavailable). Let me know if I can do anything to give a better backtrace. I've tried to install the xserver-xorg-video-nouveau-dbg package, but that didn't seem to give any better backtrace. Thanks
I should note that the problem is with the 64-bit version only. I've installed a second test-system using a 32-bit system, and I cannot reproduce the crash there. If you wish, you can close this. I no longer have a problem. Thank you for your time
Ok, let's assume it's fixed. Please reopen if you can reproduce it on xf86-video-nouveau >= 1.0.3.
