Today, in our post we added a brief, elemental guide to fix a particular inconvenience that sometimes happens with new kernel versions on Ubuntu. In fact, every time I decide to upgrade the kernel I have big problems with my graphic card (NVidia) and when rebooting I am not able to see my screen. I think that one of the possible problems is the AWN (a -MAC style- bar) I have installed on my PC. After many wasted hours trying to fix this matter I find a very fast solution. I start my Ubuntu 8.04 in the safe mode (sometimes using the previous kernel version) and I launch EnvyNG (Applications - System Tools - EnvyNG) to automatically reconfigure my video card. I know that probably this is not the most advanced way to fix my kernel problem but you can believe that it is very fast and effective. Try it if necessary!
