Oh man, I totally forgot to confirm what I had said a few weeks ago. IT IS a hardware issue. I opened up the laptop multiple times to check various settings. Anyway, long story short, bending (pressing hard on) the keyboard makes the keyboard plate (which acts as a giant heat sink) touch the ATI chip, and the heat quickly vanishes, and so do the symptoms stated above.
So if you cool well your ATI chip, that fixes it. At least for me. -- Display corrupted with red pixels, eventually freeze, IBM A31 https://launchpad.net/bugs/44611 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
