The logs attached to this bug indicates an error originating in the Nouveau video driver on startup, which has nothing to do with Compiz (other than the video driver does not then offer required functionality for Compiz to run) or the Intel video driver.
[ 8.553] (EE) NOUVEAU(G0): Failed to initialise context object: 2D_NVC0 (0) If the problem occurs only with certain versions of the Linux kernel, it's likely the problem is either in the Linux kernel or in the Nouveau video driver and not Compiz. The original description of this problem indicates an error originating with the Intel video driver, which has nothing to do with Compiz (other than the video driver does not then offer required functionality for Compiz to run). If the problem occurs after upgrading the video driver or kernel or only with certain versions of the kernel but not Compiz, it's likely that the video driver or kernel is the cause of the problem and not Compiz. It is not clear from the logs and the description of this report it two separate and unrelated video driver problems or kernel problems are being combined into one bug report. It's fairly clear it's not a problem that can be solved by the Compiz package. ** Changed in: compiz Status: New => Invalid ** Changed in: unity (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
