I have an old HP dc5000 SFF and I updated the BIOS from 1.00 to 1.43. Before that update, I install Ubuntu 11.04 Natty Narwhal and flickering and tearing occurs everywhere. So I reinstalled Windows and flashed the BIOS and installed Ubuntu 11.10 Oneiric Ocelot. The flickering was gone for some weird reason... Before that, I upgraded from an Ubuntu 10.10 Maverick Meerkat to Ubuntu 11.04 Natty Narwhal and the flickering was also gone. Did that BIOS update fix all this?
My specs are:
HP dc5000 Business Small Form Factor, Ubuntu 11.10 Oneiric Ocelot 32-Bit, Intel Pentium 4 2.40 GHz, Intel 86865g Integrated Graphics, 0.99 GB RAM
Just tell what happened. Just out of curiosity.
