When now feature of mousetweaks is enabled, the mousetweaks process normally does not run; so it should not be responsible for the problems that you see.
Considering your remark about gksu, I wonder whether at-spi is not the root of the problem. In fact, at-spi is known to be incompatible to gksu and the incompatiblity shows up when there is a program actively using at-spi. (This might explain why mousetweaks seems the culprit.) Since version 2.31.3, mousetweaks does not need at-spi anymore. In lucid, you can install a version that does not need at-spi from the following PPA: https://launchpad.net/~frafu/+archive/ppa?field.series_filter=lucid If you do not need at-spi for something else, you could try disabling at-spi and use mousetweaks from the PPA indicated here above. Please, let us know if the problem continues to occur when at-spi is disabled. -- mousetweaks went to 100% cpu load and X system is frozen https://bugs.launchpad.net/bugs/384754 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
