If you installed Ubuntu yourself and haven't intentionally replaced your video driver with the ATI proprietary one you are probably using the built in one. I skimmed the thread and saw that it could be related to your shared memory size and/or kernel version. Shared memory can be changed in your BIOS, kernel can be upgraded to with synaptic / apt but first you will want to compare the version you are on the the version that supposedly fixed the problem for one of the forum posters.<br> <br><div class="gmail_quote">On Mon, Sep 20, 2010 at 11:42 AM, Stephen Nichols <span dir="ltr"><<a href="mailto:ChinnoDog@lonesheep.net">ChinnoDog@lonesheep.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> I think they are talking about the restricted drivers are on the System menu on the Administration submenu called "Hardware Drivers".
