Ubuntu 12.10 (Unity) - window resize stopped working

[ArlieS]

Yesterday I decided to reboot my system and install the latest patches. (Alas, Ubuntu isn't stable enough that I can keep it up for months at a time.) I had last rebooted 21 days previously. I don't remember for sure, but I had probably installed the latest patches at that time.

I used the "Software Updater" GUI to do the update yesterday; IIRC, it took me to some GUI interface that presumably wrapped "shutdown -r now" or similar. In any case, I definitely rebooted after the update.

It came back up without problems, and I was able to resize some windows, but within a few hours (4 or less), I became unable to resize windows. There's a yellow outline still stuck on my screen from the first resize attempt that failed. Immediately after that, I believe I couldn't even get the resize cursor, using the method of grabbing a window corner. Later I got the cursor back, but it's a no-op. Right clicking on the window title bar and selecting resize gave me a resize cursor, which had no effect.

My laptop was not unusually loaded. It does however have a history of issues like losing its monitors, getting confused on suspend, etc. (I blame this on lenovo )

Is this a new bug, or an old one? Where would I find any diagnostics which Unity might be producing?

Thanks for any insight.

Try upgrading to the latest ubuntu version, or get the LTS version. That (sometimes) fixes problems.

Be sure to read the Release Notes.
