hi, is this still an issue with up-to-date 12.04?

[Nicolas Delvaux (malizor)]

@Chancellor: Yep, I just had this crash (apport directed me to this bug report).

[LinuxPusher (linuxpusher)]

My Compiz also just crashed, Fresh install.

[krikit (wdean84)]

Just installed XRDP and attempted to use terminal services from a windows box to connect - Compiz crashed a few minutes into attempting to load the desktop of the RDP session. The RDP session did not fail, is not hung, mouse moves but no icons or dashboard shows up, just the background that I had configured. Leaving the session for 5-10 minutes (had to register Launchpad to post) has no change.

Fresh 12.04 install from torrent tonight. System using terminal services to connect is Windows 7 Ultimate.

Chose to relaunch Compiz, and it seems to be working fine. No full system crash.

same issue login using xrdp, but no launcher icons nor the top bar. I intend to use this computer as media/VM server without any devices connected to it. Currently trying to set it up with display, keyboard and mouse connected, compiz crashes when logging in from another PC using xrdp.

Same symptoms on a remote login using NX Nomachine.

I have had the same bug. I have a dual nvidia card (2 or 4 monitors) ge 440 and gt 550 ti. The problem is only when I try to use xinerama mode in unity 3d with dual card. gone 3 does not work. unity 2d and kde+kwin works. I laso have xrandr error about missing parameters (when I use unity 2d)

[Paul Graydon (twirrim)]

Affected me last night, spawned off a tightvncserver instance, connected and got no launcher or icons.
