    Thanks for posting your specs. It appears to be the same as mine except for the wireless which I also changed out from a broadcom 4313 to a broadcom 4312 (very poor performance). I will test 13.04 and post the results.

    I verify that 13.04 (build from 20130311) running from a live USB does fix the backlight dimming problem on my system. Now we'll have to see if it still works when doing an upgrade from 12.10, once 13.04 is released.

    I just upgraded to the latest kernel and other updates to my 12.10 system using software updater and the problem appears to be fixed!


    Code:
    jweber@nardis:~$ uname -a
    Linux nardis 3.5.0-27-generic #45-Ubuntu SMP Tue Mar 19 23:38:37 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

    I think you might get 3.5.0-27-generic #45 if you enable quantal-proposed (as I have) in the software updater. Look at the info on

    Thank you for this thread. I wanted to learn if this computer was compatible with Ubuntu. A review on Amazon said the graphics didn't work well. Though this thread didn't actually say it had poor graphics or good graphics, the absence of comments about it gave me confidence to buy one. Knowing that one problem with the brightness has been sorted out with 13.04 is good news.

    I hope the other features like Bluetooth and WiFi work well. Though Acer says it works only with a maximum of 4 GB RAM. I've seen an expert tech say on a video that this model will accept 8 GB and work even better.

    Seeking an Aspire One A0725-0600 soon.

    I just ordered an 8GB upgrade based on what I read in various reports. We'll see!
    Is there a better, more preferred thread for the ram and WiFi and other topics...like a general forum or thread for this particular laptop?
