I have recently upgraded to Maverick beta from Lucid. I thought to wait until the final version is out, but I gave in to the excellent reviews I read so far about this new version.
So, here is how things are for me. The upgrade was Ok, I rebooted and then surprise! I cannot click my mouse on anything. The icons do not even "light up" on hover.
I can move the cursor on the screen, though. I thought it might me just a known bug that will solve after a few updates. But here I am a week later and still no resolution. I searched this forum and Google but I did not find a similar problem. My system is on 32 bits.
I also installed the xubuntu-desktop package and on that DE everything works.
My mouse is an A4tech X-718BK, if it matters.
Now I am at work, but later in the evening I will be available to answer your questions, if any and try solutions.
So what happens on the ubuntu desktop that my mouse is not working?
