Ubuntu version 13.10 – update from 13.04 hints
Sunday, November 3rd, 2013
Ubuntu version 13.10 is available for download and update. If you uses earlier version of Ubuntu and just plan to update from version 13.04 to version 13.10, the Fortune is with you. You are the Lucky Boy/Girl (select your own). You may read this post 1st, and then, you will be ready to install this 13.04 to 13.10 update.
Unfortunately I was not ready so good as you could, and spent the couple of hours digging Internet to find the right decision for 3 little problems I met after my computer with updated operating system successfully rebooted. The 3 problem, little but critical, as anyone could stop your work as a Web developer.
It would be honest to say, that the troubles, which I will describe in this post, are not related neither to the operating system Ubuntu itself, nor to its version upgrade process. There are no bugs and no crashes. I may talk about my case of course.
You will meet the real problems in case you are the developer and have Apache/PHP installed at your desktop/server with a lot of virtual web servers defined. Add our popular and lovely WordPress here. Otherwise all update process took, of course, some time, but was fulfilled smoothly and without any headache.

Terminal window size and position in Gnome Ubuntu
Sunday, July 10th, 2011Me do :).
Are you tired doing this not too much smart job instead of making something useful? My patience is finished today. After about 1 year of every day clicks to change terminal window size and position to more convenient for me I finally turned on my curiosity and “googled” the subject. Success! A lot of people met this problem, asked about it on forums and of course decision exists. Thanks to Ubuntu community for sharing that with us.

Remove Old Linux Kernel from Ubuntu Bootloader Menu
Sunday, October 3rd, 2010GNU GRUB version 1.98-1 ubuntu 7
Ubuntu, with Linux 2.6.32.25-generic
Ubuntu, with Linux 2.6.32.25-generic (recovery mode)
Ubuntu, with Linux 2.6.32.24-generic
Ubuntu, with Linux 2.6.32.24-generic (recovery mode)
Ubuntu, with Linux 2.6.32.25-generic (recovery mode)
Ubuntu, with Linux 2.6.32.24-generic
Ubuntu, with Linux 2.6.32.24-generic (recovery mode)
These additional menu items for older Linux kernels make available recover option in case of any accident with your current Linux kernel. It is right. We should to have at least 2 Linux kernels load options: current version and previous one. But with every Linux kernel update quant of such bootloader menu items grows. What to do with it? How to exclude unneeded Linux kernels from the bootloader menu? Yes, that’s possible and (don’t wonder) quite simple.
