This bug is killing me. It started around 11.04 and is still present in 12.04 for me. I'm running the binary nVidia driver (Machine has a Quadro FX1600m). Something seems to have changed as recently this has started dumping my session (Cinnamon 2D) out to login rather than just locking the machine solid.
It used to be that only the Second Life (SL) viewers were affected by this (I use the firestorm viewer that can be downloaded from http://www.phoenixviewer.com). A curiosity is that the screen generally flashes to black before it crashes and returns with textures from other windows (like title bars) baked into the 3D environment within Second Life. When you quit Second Life, it save a copy of your current view as the "last location" photo. If I quit before it crashes while the stolen textures are on the screen, they are saved as part of the photo. This might have various implications. Unfortunately, the change isn't all positive as now (since 12.04) the lockups are happening when using normal desktop apps instead of just Second Life. This is happening on a daily basis and is becoming very annoying. I tried installing Fedora 17 on my other HD and it seemed to run fine without this problem. Another strangeness which I don't know if it relaed is that since 11.04, my Second Life frame rate is going down. If I run it in Ubuntu, I get <10 FPS (often <1 FPS) but when I tried Mint Maya Cinnamon I get 25FPS. In Ubuntu, I tried Unity, Unity 2D, Gnome, XFCE and LXDE with only LXDE producing vaguely acceptable frame rates. This makes me ask the question "What is it that has changed on Ubuntu that is common to Unity, Gnome and XFCE but isn't in LXDE?" I got the following dmesg from the lockup I just had: [28068.719328] NVRM: Xid (0000:01:00): 6, PE0001 [28088.780505] ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4] [28088.780509] ecryptfs_readpage: Error decrypting page; rc = [-4] [28107.454335] delay: estimated 133, actual 0 I use an encrypted home folder and swap. Could this be somethign stupid like a bad block in my swap file or home where the SL cache is stored?
